Peter always loved Star Trek. He grew up watching it with Uncle Ben and it wasn’t until he met Ned that he really got into Star Wars. So when he gets invited to go on a treaty mission with the other Avengers on another planet, he geeks out a little bit. 

Peleca Four is a gorgeous mostly water planet with beaches and vivid vegetation as far as the eye could see. Hot water pools and fresh springs were everywhere, people splashing and lounging. The people here sort of looked like mermaids without tails, pastel colored and pretty. 

Thor called it a pleasure planet and Peter had seen enough Star Trek to know that meant a lot of nakedness but it wasn’t actually that bad. There was a weird undercurrent of sexy everywhere, even though people were clothed. Maybe it was just the fact that everyone was hot and Peter was horny. Something that one of their guides seemed to pick up on quickly.

“Come with us,” Melica giggles, tugging on his head. She’s quite literally, the princess, married to the leader of the planet. The one that Tony and Steve were talking to now. Peter hadn’t really left Tony’s side, not wanting to get in trouble and he looks at him now for assurance. 

“You can go,” Tony smiles encouragingly. “Have fun. Learn something. Just try to keep him in the castle, huh Mel?”

“Okay,” she giggles again, her voice bubbly and light. “I won’t take him far, don’t worry.”

Before Peter can even really decide if he wants to, she and a gaggle of girls take him away. The gender dynamics on this planet could only be described as stereotypical. The men were huge, super soldier sized and muscly and broad. The women were tiny with curvy hips and tiny waists that they seemed to love to accentuate. They hadn’t seen many kids but they’d seen some teenagers and even though they were slightly less mature, they had the same typical traits. 

Naturally Peter in all his twink glory confused them.

“We’ll show you the pools!” Melica says excitedly. “And oh I’ve got the most perfect outfit for you!”

“He needs pearls Mel!” another one chatters, adopting the nickname that Tony had given her. He’d been handing them out left right and center and they all got a good giggle out of it. 

“Wait, outfit? Pearls?” he asks in confusion. Was the translator working right? “You-you want to dress me up?”

“Of course we do! That’s what’s fun around here!” another girl giggles. “We all spend time at the pools and get pretty for the husbands.”

There’s a weird warble on the word husbands that lets him know it’s a correct translation but not perfect. “And you want me to join because…”

“You are a wife, no?”

Another warble. Maybe husband and wife were the closest the translation spell could get to their gender identities. “Uh, no?” he questions. “I mean I don’t- I don’t think I’m like you.”

“Well let’s find out!” Melica laughs. 

They lead him into an atrium and his face flushes when he sees the entire room is full of naked girls. Tiers of fresh hot water springs stack through the space like a tiered fountain. There are girls lounging on the edges, swimming through the water, combing each other's hair. It’s like the universe's biggest mermaid sleepover and somehow he got invited. 

His little group drags him over to a fairly empty pool and then starts to strip him. He yelps a little and they giggle but then he realizes no one is taking their own clothes off, another girl does it for them. Okay, so maybe it’s just a thing. 

“Uhhh, can we just be careful with that!” he panics when they try to take the web shooters off his wrists. 

“Did your —- make it for you?”

He blinks at the missing word the translator skipped over. “Who?”

“Tony!”

“Oh! Yeah he did,” he nods. Then he points to the IronSpider casing and his clothes. “And he made that and bought me those.”

They all let out soft sighs and then suddenly they’re treating his things like they’re precious. “Such wonderful gifts!” one of them sighs dreamily. “Tony must be an amazing — “

“Uhhh, yep,” he nods. Smile and wave right? “He sure is.”

They all burst into excited squeals and giggles and then finally divest him of his underwear. They’re all immediately interested in his cock and he doesn’t really know what to do about it. When he tries to cover himself, two girls grab his wrists and hold him with shocking strength, while the other ones investigate and touch his dick and balls. 

“Oh it’s so pretty!” Melica declares and he relaxes slightly. “You’re so lucky there’s a party tonight. You’ll be the prettiest wife there!”

“Are we sure he’s a wife?” another girl asks skeptically as she hefts his balls in her palm. “These are husband parts.”

“He’s from Terra silly, maybe sometimes wives have husband parts there! He’s too pretty to be a husband!”

“Yeah! Get him in the water already!”

He squeaks, his spider senses tingling just before they all drag him into the pool. The water is blissfully warm and he tries to relax into it. It’s just swimming right? Then he notices a weird tingle all over his body. “Uhhh, what’s happening?”

“We’re making you pretty, duh,” Melica laughs before pushing his head under so his curls get wet. He comes up spluttering and once more he’s surrounded by girls, their hands touching him everywhere. He tries to protest but Melica stops him with a hand on his chest. “You wanted to learn about us, right?”

“Well, yeah,” he nods.

“Trust me,” she giggles. “This is more fun than whatever the husbands are talking about. We’ll teach you the good stuff.”

“Well… okay,” he nods, trying to establish some agency over his situation. “Pretty me up or whatever! I’ll be a good sport.”

“Yay!” they all cheer. 

The pools, he’s figuring out, are like a Roman bath situation. Several girls swim to one of the edges and pull out little vials and objects that look like loofahs. More of them attach to his arms and hold him there while the others start to wash him. He squirms and blushes as their tits rub against him. He’s got a heavy preference for men (okay for Tony) but he thinks you’d have to have an iron will not to find this whole thing slightly erotic. 

“Oh my god!” he yelps when soapy, slender fingers push into his ass. 

“Oooo, his pussy is so tight!” the girl giggles. There’s a lot of chattering and suddenly he’s got alien girls taking turns fingering his ass, despite his protests. 

“Ooo, he’s tight up here too!” Mel declares, rubbing her thumb over the tip of his cock, right over his urethra and he shudders at the sensitivity. 

“Oh! I’ve got just the things!” the girl who had declared he needed pearls cries and she quickly swims away. His spider sense tingles but these alien chicks are surprisingly strong. She comes back holding, shocker, two strings of pearly orbs, one small and one much, much larger. “He’ll look so pretty in these!”

“Uhhh.”

“Oh you’re right! Quick! Lay him out!”

They manhandle him over to a ledge and lay him out on his back, spreading his thighs apart. His breathing quickens as more vials appear out of nowhere and suddenly a light blue sticky liquid is being poured over his cock and then worked into his ass.

“Oh god,” he groans, panting as his enhanced senses make him want to cum really bad all of a sudden. “Um, this really isn’t— humans usually ask first.”

“Ask what? To groom each other?” Melica asks curiously. 

“This isn’t really- it’s not- oh fuck!”

Someone had hit his prostate and he gasps as tingles light up his spine. A bubble of pre-cum squirts from his tip and he flushes with embarrassment. How is he going to explain this to Tony and the others?

“Why isn’t he getting wet?” a girl huffs. 

“Maybe husband-wife humans don’t get wet?”

“Well they should!”

“Ooh he’s got a special button in here! Hand me the gel!”

“How does Tony even fuck you if you don’t get wet?”

Peter chokes on the words. “What?!” Oh god he’s done it now. They thought Tony was his fucking mate or something! 

“Aw he’s so tense. He needs something to suck on Mel!”

“I got just the thing!” she giggles and then her breast is being shoved into his mouth. She massages it and warm liquid starts to pool down his throat, a little fruity and a little sweet. Was she breastfeeding him? What the fuck? 

“Oooo smart Mel! Tony isn't going to know what to do with him when we’re done!”

“I wonder how many eggs he’ll lay in him!”

Peter groans and squeezes his eyes shut. He really should’ve asked more questions first. He tries to push them off, actually putting his strength into it but they all giggle and pin him down again. Jesus fucking Christ. The mermaid alien chicks are stronger than him. 

“Be careful with that Adrina! Humans are fragile!”

“I know what I’m doing!” Pearl girl chirps, rubbing her thumb over his slit again. “You fix up his pussy so I can put the pearls in and I’ll worry about his clit!”

“Okay,” they giggle. 

Adrina rubs more lube over his slit before she rubs one of the tiny pearls over it. She pushes and it pops into his entrance. It burns with no prep and he thrashes in pain. “Oops! Sorry! I’ll get a rod first!”

Peter gurgles his in protest around the milk pouring down his throat but that’s about all he can do. Melica giggles above him. “Silly little husband-wife. Beauty is pain sometimes, don’t you know? Your clit is going to be so bumpy and pretty! And when we’re done here I have the prettiest piercing to hang off the tip!”

They are insane, but the tiniest part of him is enjoying this. His cock, clearly is enjoying this. And when Adrina returns with a thing that looks like a wiggly but straight piece of coral he whines. She lathers it up with the light blue lube and then pushes it into his slit. He groans loudly and all the girls giggle. The rod sinks in like it was made to be there and his eyes roll back with pleasure. 

Meanwhile in his ass, the girl who had found his prostate is milking it relentlessly, rubbing something tingly and viscous into the tender spot. It’s just soft enough to not get him off and he doesn’t even know if he could cum with the rod in his dick. Also there’s a strange mental block happening inside him, like something is preventing him from cumming. 

“He makes such pretty noises,” a girl giggles. “But he’s so empty and needy! Does Tony not take care of him?”

“Maybe they just have different grooming standards on Terra.”

His mind whirs and tries to keep up. They thought being stuffed and horny was the same as pretty and well loved. Peter with his empty ass and cock looked neglected… and maybe ugly? No, they called him pretty from the start. This was like a boyfriend buying him makeup and jewelry. Oh god, don’t think about Tony being a sugar daddy right now or he’s going to-

He makes a strangled noise around Melica’s breast as his whole body spasms at an attempt at an orgasm. His eyes fly open wide when he realizes he can’t. It’s like the world’s most intense edge and he groans as all the girls burst into giggles.

“It’s the pool water,” Melica explains, tracing one sharp fingernail around his nipple and making him moan. “It keeps us from finishing. When a wife gets mated to her husband for the first time we bring her to the pools for at least three solar cycles, preparing her to be a —! When I mated with Haliven it was for seven! I could barely get through the ceremony. I needed his cock so badly!”

Oh lord. He’s going to be horny and desperate until they go back to Earth and he can jerk one out. Seriously, how is he going to explain this to Tony?! At least he’s learning.

Adrina pulls the rod out at that moment and his balls draw up again, but all that comes out is more pre-cum. He moans, breathing heavily through his nose as he has to keep suckling so he doesn’t choke. He could make an educated guess that her breast milk is probably an aphrodisiac. 

“Okay, let’s try that again,” Adrina giggles. She pours lube over his tip and he stiffens when he feels it drizzle into his cock. Then he feels the first pearl pop in and he spasms again. Holy shit, why does that feel so good? 

He glances down and his eyes widen when he sees how long the string of pearls is that Adrina is holding. It’s wrapped around her hand to stay out of the way as she presses another bead in, but it must be four or five times his actual length. How was that all going to fit inside him? 

“He’s still not getting wet!” a girl pouts. 

Because I don’t have a pussy! he mentally screams. 

“Well get the slugs then! That’ll fix him right up!”

Slugs?!?! He seizes in panic but Melica pins him down, brushing her fingers through his curls. “Don’t worry it doesn’t hurt,” she giggles. “Your pussy will be sooooo drooly, it’ll feel so good.”

He whines weakly as she starts to play with his nipples again. Adrina has got at least five pearls in his cock now and each one is slipping in faster, rolling against his insides. The girl massaging his prostate at least relents but it’s only a short reprieve because soon he feels something thick and slimy being pushed into him. Are they seriously putting a slug in his body? 

But then it starts to wriggle and oh god it really is. 

“We all use them, it’s totally safe,” Melica explains, giving him a pinch that sends him into another spasm. 

Peter groans as they shove another one in and the slugs work their way into his guts. All of May’s horror stories about idiot teenagers who stuck things up their ass and ended up in the ER are coursing through his mind. But god they had really fingered him open and the slugs don’t go too deep. Hopefully they’d come out. Then he feels a little pinch in his ass and he yelps. 

“There they go!” someone giggles. “He’ll have the wettest cunt on Terra once we’re done with him!”

More girls appear and grab his hands and start fussing over his nails and rubbing oils into his skin. He whimpers when he feels more pearls slip deep into his cock. He can feel them gathering at the base now and there’s still so many to go. Adrina puts another one and gives a good push and suddenly something pops deep inside him. What the fuck?

“Ooo perfect! They went in his chamber!” she declares and all the girls make excited noises. 

Chamber? What- oh god, his bladder? She was going to fill up his bladder? 

His ass tingles and occasionally he feels a little pinch. He wishes someone would explain what these slugs do instead of just telling him he’s going to be wet. His eyes drift shut and he just tries to breathe as all the girls around him chatter and giggle. 

His mind wanders to Tony again. What was he going to think? They haven’t even dressed him yet in whatever outfit they had planned. Was Tony just going to get mad that he let this happen? No, he’d probably get mad that they did this to him. Tony never blamed him. But what if— 

A soft moan escapes him as he imagines Tony liking it. He imagines the older man pinning him to the bed and investigating every inch. Fingering his wet hole and pulling out the pearls from his cock one by one. He imagines the rough scratch of his beard against his chest, roughing up the puffy nipples. Oh god he wants it. 

His body spasms again and the girls erupt into a fresh wave of giggles. “He and Tony must be so in love,” one of them sighs dreamily. “He spasms so pretty!”

“Melica, we should do something with these!” another voice says, pinching his other nipple. 

“Get the suckers,” she says. “He’s already sensitive and he’s a husband-wife, remember? I think his tits are supposed to be small. I have piercings that match the one for his clit we can add later.”

“You got it, your highness!” 

Right. Princess. That’s why they were all doing everything Mel wanted. 

He doesn’t want to watch in case it’s another sea creature they’re putting on his chest. Based on the wet suction that suddenly envelopes his nipples he thinks it is. He whimpers as his areola is sucked and he knows they’re going to be fat and sensitive when this is over. They’re already one of the most sensitive parts of his body. 

Meanwhile, his stomach is starting to feel heavy and full like he needs to pee. When he shifts he can sort of feel the rolling of the string of pearls inside him and it’s not an unpleasant feeling. His ass feels sticky and wet as promised and he wonders if it’s just the slugs secretion or they really did something to make him create his own lube.

“Aw, look he’s finally relaxing,” Adrina coos as she pushes more into his dick. “He was so stressed, poor thing.”

“I know,” Melica giggles. She pulls her tit from his mouth and he sucks in a deep breath of air, but then she sticks the other one in and as a fresh burst of milk slides down his throat he realizes he’s drained the other one dry. “He’s so thirsty! Poor humans, their life must be so hard!”

He can’t help but hum in agreement and they all giggle again. 

“Annnnd done!” Adrina declares. He moans and looks down as she takes the last few pearls hanging out of his cock and loops them around the base, somehow tying them off. Then she takes her hand and strokes his entire length and he seizes. Fuck, that feels good. Every pearl runs and teases at his insides, and all he can think about is how Tony’s hand is so much bigger. “You girls ready for me back there?”

“Think so!” someone giggles, wiggling their fingers into his ass and pulling out the slugs. “Get him in the water so we can rinse.”

He whimpers as they scoot him down the edge so his lower half is in the water again and fingers start to pump into him, letting the water rinse away the slug slime. But then after that there’s the lingering sensation of dampness that feels like lube. They keep fingering him for a moment and Adrina even strokes his cock. When he spasms again he feels something burst, and then it’s like someone dumped a shot of lube in his hole. 

“It worked!” they cheer. 

Jesus Christ they gave him a pussy. 

“Let’s get these in!” Adrina says, pushing the others out of the way. “We don’t have all night!”

“No, that’s for Tony,” another giggles. 

Peter groans. This is going to be so embarrassing. 

He’s so open that the big pearls in his ass just feel nice. They glide into his slippery hole with no issue, and there’s way less of them. It’s like his ass is sucking them in one by one and he moans when Adrina ties them off by bringing the string between his balls and attaching it to his cock, leaving one pearl out and rubbing at his perineum.

Once that’s done, they pry the creature off his chest and Mel takes her tit out of his mouth. He just manages to take a deep breath before they dunk him under the water again. Everything is moving and rubbing inside him and he sort of dissociates as they clean him again, his body occasionally spasming in a denied orgasm as they wash his hair. 

“Gently now,” Melica coaches him when they get him out of the water. He groans as his body feels heavy and they let him lay on something soft as they oil his skin. By the time they’re done, he’s a little more with it and aware. “Wrap him and take him to my chambers to finish. And take his things to his and Tony’s room. Be careful with them!”

They get him to his feet and he has to lean on two girls as they bundle him up in what’s basically a towel and make him walk. Her chambers are apparently attached to the pool room so at least he’s not showing off his bits to the whole world. Then they make him sit on a stool and he gasps at all the pressure it puts on the beads inside him. 

Makeup is applied to his face and when he looks in the mirror he’s stunned. He looks amazing, and also straight out of a porno. His lips are slightly swollen and his eyes are glassy, every high point on his face shimmering with sparkle. He’s so distracted he doesn’t even notice them pushing needles through his earlobes until he feels the tingle of his enhanced healing as they slip dangling pearl earrings into the holes. 

“Uhm, I don’t know if—“ he stammers as they move to his nipples next. They pierce through them before he can finish his blabbering and he moans at the pain. Okay so maybe he’s always wanted that done anyway, it’s fine. And the little gold hoops with pearls are really cute. 

But then they’re grabbing his cock and he freaks. 

“Relax,” Melica soothes, putting her hands on his shoulders. “It doesn’t even hurt you, right? You didn’t flinch at the others. Do humans not feel pain?”

“Oh I felt it,” he says deliriously. “I just handle it better than a lot of people.”

“Trust me,” she says, moving around so he can see that she has a piercing dangling from her clit and it makes him blush. “He’ll love it.”

Oh. He whimpers, knowing Tony won’t see it but imagining his reaction anyway. It would be fully healed by the time Tony got to touch it. He could play with it, make Peter go mad with pleasure while he couldn’t cum because he has so many pearls in his dick that they’re in his bladder. Speaking of, he has to pee so bad he thinks he might explode. 

“Okay,” he whispers. 

They hold him down and he spasms when the needle goes through, bumping against the pearls inside him before going back out behind his glans. He has to lean back against Melica as they thread the piercing through, breathing heavily. It’s a gold bar with a pearl near his glands and a dangling little set of pearls that match his earrings hanging from his tip. They look like little drops of cum, frozen in mid air as he spills and it’s so erotic it makes him feel insane. 

Tony is going to be so mad at him. 

“Now you can get dressed!” Melica giggles. 

The outfit involves a corset, because of course it does. They make him brace on the vanity and he gasps as they lace him in tighter than his male body should allow. His cock bobs with every movement and he whimpers when he sees how the garment pushes his pecs up to look like real tits. 

Then comes the dress, white silk that flows around him like water. It’s a halter top and they tie the bow behind his neck with a flourish before fussing with the top edge so just the barest curve of his pecs are showing. He’s starting to realize why there’s not naked people everywhere you see here, it’s because they keep it all under the surface. The skirt is short but not lewd except for the fact that his cock keeps pushing it up and the girls aren’t happy about it.

“What do we do?” Adrina huffs. “This isn’t going to work!”

“Oh! I know!” a girl gasps. Most of them had gotten distracted with dressing themselves and Peter had ignored how many phallic insertions seemed to be involved in the process. She comes back with a white ribbon and then grabs his cock, pulling it backwards. Because it’s hard, it makes him shudder and groan, feeling every little pearl inside him. She ties a bow around his shaft and then ties another bow around the string between the bead in his ass and the one against his perineum, keeping the front of his crotch flat. 

“I can’t walk like this!” he protests as every little movement tugs and sends shivers up his spine. “Or sit!”

“Yes you can,” they giggle as they slide his feet into sandals that lace up his calves. At some point they’d polished his toes. “We’ll help you practice!”

He groans as they hold his hands and walk him in circles sound the room until he can do it without sounding like a dying elephant. Then they make him practice sitting, finally finding a kneeling position that is semi-comfortable. He complains a little and Melica just smirks at him. “Just think about Tony,” she says and he shuts up. 

He’s set to the side for a bit as they all finish getting ready. It’s a bit of a reprieve and the girls actually hold a conversation with him, happy to talk about how they make nail polish and makeup here. He doesn’t ask about the slugs or the suckers. He doesn’t want to know anymore. 

Melica looks beautiful in an outfit that mimics his but in soft pearly pink instead of white. Once all the girls are ready she tucks his elbow into hers with a grin. “I’m so excited you’re here tonight!" she says as they exit into the halls of the castle. “It’s a full lunar!”

“Why is that special?” he asks weakly. 

“There’s a substance in the air called Pelium. When the lunar is full it charges and it makes you horny!” she giggles. “More horny than it normally does anyway.”

Oh dear god, that’s why it’s a pleasure planet. They’re all breathing aphrodisiac air! Do the others know that? Fuck. Fuck. Fuck. 

Before he can panic about it they’re bursting into a grand entrance hall. The castle is on a beach and this part must be underwater because the ceiling is a dome of moonlit ocean with coral and fish swimming between the moonbeams. There’s already hundreds of people swarming around and when Melica and he enter, they curtsy and bow to them. Right. He’s the princess’s special guest. 

At the front of the room are a few grand but low chairs with cushions in front of them. Melica points him to a lilac one on the floor and he sits without questioning it. She sits on a pink one across from him with a grin. He glances around and notices that most of the room is set up like that, with tables full of food scattered between the chairs. He swallows hard when he sees men sitting on the chairs and women sitting on the cushions. But there are also gaggles of women sitting in little circles of chairs with no men in sight and vice versa. Then he looks at the chair next to him with wide eyes. Was this a mate thing again? 

Before he can ask her, there’s some sort of fanfare and everyone faces them, or rather something behind them. There’s a lot of footsteps and then in a low tone, he hears. “Do you see Peter?”

At the sound of Tony’s voice, Peter’s whole body spasms again. He bites down on his lower lip with a gasp, trying to keep himself contained. Melica smiles at him knowingly.

“Tony! Please, come sit as my guest of honor,” Haliven says in a booming voice. 

“I’d love to, but I really should find—“

Peter lifts his head and turns to look at Tony, having no idea how he’s going to react. 

★★★★★

Tony was honestly having a great time. A pleasure planet was right up his alley, but he’s also a businessman and doing trade negotiations with mermaidia is fun. Steve and the others had found their own interests, and they’d spent the entire day soaking up information like sponges. 

He’d missed Peter though. He hadn't expected the boy to be gone all day but when asked where he was, Haliven, the ruler, laughed and clapped him on the shoulder. “Let the wives have their fun, Tony, and we’ll have ours tonight, huh?”

That wouldn’t have made a ton of sense if Tony hadn’t already figured out that the translator could only use husband and wife as a closest approximation to their words for gender identities. Peter had greatly confused them in this walking porn world, though Tony thinks they’re missing out by not knowing the enjoyment of a good twink. He tried not to worry, but he’d still felt like not having Peter as his little shadow was a loss.

They’d given them rooms and new clothes for a welcome party. The fabrics here are incredible and Tong makes a note to hype it up. They’d make big bucks on earth and he wants to take a few bolts home to make Peter some clothes. He’s sure they’d feel amazing to his delicate senses. 

Now he’s walking into a fancy party, in a slightly pirate style shirt in soft silky blue and makes him feel hot, even if the cream pants hug his ass and dick a little too tightly. They didn’t have bright or dark colors here. Everything is pastel. His eyes scan the room for Peter and he frowns when he doesn’t see him. 

He leans over to Steve with a soft murmur. “Do you see Peter?”

“No,” he murmurs back.

“Tony! Please, come sit as my guest of honor,” Haliven says loudly, gesturing to the seat beside him. Melica sits on a cushion at his feet and beside the other chair is… another girl? 

Tony gets a weird feeling in his gut, hoping they haven’t tried to give him a prostitute or something. For whatever reason, they had deemed Tony the leader of their little crew and kept treating him like royalty. He clears his throat, not wanting to be rude. “I’d love to, but I really should find—“

His voice dies in his throat when the girl turns, but it’s not a girl. It’s Peter. His curls have been artfully scrunched into ringlets and there’s makeup on his face. He looks pinks and flushed and horny. His eyes are slightly glazed over even though he’s looking at Tony like he’s afraid. 

He’s wearing a dress and his chest heaves as he exhales shakily, showing off his cute boy tits. The white silk halter tied around his neck in an artful bow makes him look like a present made for Tony to unwrap. Pearls drip from his ears and he’s holding himself a little bit funny. 

“Peter?” he whispers in shock.

“Hi,” he says in a soft voice, looking shy. 

Haliven and Melica both laugh, looking smug. “Sit, Tony,” he chuckles. “You can admire your — while we eat.”

“Uh- my what?” he asks, the word not coming through. He sits though, not sure what else to do. “That didn’t translate.”

“Oh, did it not?” Haliven asks curiously. “Hmm, how do I explain? Melica is my —-, my life partner, my everything. She submits to me and I care for her.”

Oh dear god. Peter makes a tiny whimper at his feet, and Tony can’t help but wonder what he’s been through. Still he panics, and he pulls up a little holo screen, adjusting the translators he’d made that they all had tucked in their ears like comms. “Uh, okay, so the translator needs adjusting. Let’s try that. Your word for man or woman is coming across as husband or wife which is uh, actually our word for that. Whatever you said.”

“Excellent! Enjoy the party with you wife, Tony. Let us show you the pleasure of our planet! The lunar is full.”

“Peter isn’t my—“ A hand on his knee stops him and he looks down to see Peter looking desperate. 

“Tony,” he whispers. “I already tried. They don’t get it.”

He flounders for a moment but then music starts and everyone starts talking and laughing. He looks over at Steve but he and the others haven’t even witnessed the exchange. They're talking and laughing, enjoying themselves as they should be. 

“Okay, okay,” he whispers. He slides his hand over Peter’s, trying not to let it show how much his white pearly painted nails affect him. “Are you okay?”

He whimpers, cheeks turning a darker shade of pink. “Uhm, sort of,” he whispers. 

Tony is about to ask what that means when a glass of something is shoved in his hand and Haliven is asking him about Earth again. He takes it and puts on his best press smile, keeping his hand firmly over Peter’s, rubbing his thumb over the soft skin on the back. After a minute he feels more pressure, and he looks down to see Peter resting his cheek against his knee. He seems almost drunk. 

In a move that’s probably a bad idea, he moves his hand from Peter’s to his curls, running his fingers through them and scratching at his scalp. The boy spasms and then moans, like he fucking came. What the hell is going on?

While Haliven talks to him, Melica is at his feet happy as a clam. Tony has dabbled in everything sexual, and he’s been to enough sex parties to pick up on the vibe. There’s almost a buzzing in the air and similarly where there’s a man in a chair, there’s a girl on a cushion, nuzzling at their partner and a little bit glassy eyed. Maybe the better words for their marital relations were dominant and submissive. 

He’s trying to have a “when in Rome” attitude and Peter doesn’t seem to be freaking out, so he plays along for a while. When Haliven drinks, Tony drinks. When he eats, Tony eats. He expects him to hand feed Melica, but that never happens and he worries slightly about Peter’s enhanced metabolism. He’s about to try and say something when Melica pushes up more on her knees and nuzzles at Haliven’s crotch. 

“Are you hungry, my love?” Haliven chuckles. Then he pulls his cock out, and oh boy it’s weird. “Take your fill.”

Melica licks her lips and then leans forward, sucking down his length. Tony’s breath hitches and he looks away, making the mistake of looking down at Peter. His stomach clenches when he sees the boy staring at his bulge with hunger, his breath a little ragged, his pupils dilated so much his eyes are almost black.

“You better feed your wife, Tony,” Haliven chuckles. “The pelium is fully charged now. It affects them first and they get so hungry.”

“The pelium?”

“Aphrodisiac,” Peter croaks, licking his lips a little. “In the air.”

Oh Jesus Christ. Tony’s going to hell, because if Peter needs it, he’ll give it to him. He won’t even hesitate. And he should really hesitate. 

He leans forward, getting in Peter’s face and resting his elbows on his knees, cupping his chin. “Talk to me,” he murmurs, knowing his hearing will pick it up over the din. To anyone else, they’d look like two lovers sharing secrets. “What happened?”

“I’m so horny,” he breathes out, eyes fluttering shut. It’s like Tony’s touch is blissful relief. “They- they- they made me pretty.”

And that’s not really an explanation but he can work with it.

“They sure did, bambino,” he murmurs, stroking his jaw. “You’re so pretty, but I need some consent here, kid. They drug you up?”

“Not exactly,” he whispers. “It’s the stuff in the air.”

“Yeah, I feel it, too,” he says softly. 

“M’sorry,” he whimpers. “I didn’t know- I didn’t understand until- until they already- please don’t be mad at me.”

“Shhh, you’re not in trouble, sweetheart,” he soothes, kissing his forehead. “Everything’s okay, but I gotta take care of you, okay? You need it?”

“Mhmm,” he whimpers, nodding as best he can in Tony’s grasp. “Please.”

“Okay, shhh, shh,” he soothes, leaning back and taking Peter with him. He lets him rest his cheek against his thigh as he gets his dick out, rock hard and ready to go. Peter moans and then spasms again. Tony grabs him by the curls and slowly pulls him forward, giving him time to back out. “Slowly, baby, there’s no rush. Take your time.”

Peter opens his lips and his eyes roll so fall back Tony sees white as his dick slips into his mouth. His mouth is way softer than it should be and when his tongue flicks up the underside Tony almost loses it. He exhales sharply, tugging him a little further, and getting his sensitive tip in the back of his throat so he can’t tease it. 

“Good boy,” he murmurs and Peter spasms again, whining weakly. He’s got little tears of overwhelm in his eyes already. “Shhh, just keep me warm, baby. Does that feel good? You can relax. I got you.”

He moans and his jaw goes slack, suckling softly on Tony’s cock in cute little pulses. It seems to calm him down a bit, especially as Tony pets his hair. He sighs softly through his nose and leans back in his chair, sipping at the wine. 

“Uhhhh. Tony?” Steve asks. 

Tony looks over and sees him also looking flushed, staring at Peter between his legs. Tony shifts his thighs so the boy is more covered, feeling a wave of hot possessiveness. “There’s an aphrodisiac in the air,” he explains. “Just- don’t judge me Steve, okay? We’re all flying by the seat of our pants right now.”

“I- yeah, okay,” he nods, looking back at Barnes with lusty eyes. Tony wonders if they’re going to cause a planet wide gender role and sexuality crisis when they eventually end up making out. “Just be careful.”

“You too,” he murmurs, before looking back down at Peter. He lingers like that for a little while, petting Peter’s curls and chatting away. He shifts a few times, his balls feeling more full and heavy than normal. It must be the shit in the air. It gets to the point of painful, and he hesitates before sighing and tugging on Peter's curls. “C’mon, bambino. Suck Da- suck me off.” 

Peter moans and starts to suck in earnest. He’s been drooling and his mouth is so wet it feels like a cunt. Tony groans softly, trying not to make a scene. Haliven is holding himself very composed and Tony thinks this isn’t the time to make big displays of fucking. The idea is that he’s feeding him, not fucking him, whatever the fuck that means. 

His orgasm rolls over him surprisingly quickly and softly, a pleasant warmth rolling up his spine. He tightens his grip in Peter’s curls and pulls him all the way to the root as he shoots off. The boy moans and spasms again, nuzzling his nose against Tony’s pubic bone. It’s precious and sexy, drawing out his finish as he fills up Peter’s belly. 

“Good boy,” he sighs softly, slowly loosening his grip. Peter stays right where he is, holding all of Tony’s softened cock in his mouth and he lets him. He takes a sip of wine, trying to keep himself pulled together both for practical purposes and erotic ones. It’s really hot to have Peter falling apart at this feat while he dines like a king. “So Haliven, you better give me a crash course on how this night works.”

The alien chuckles, having heard Tony say that phrase several times today and now knowing what it means. “Do you not have these rituals on your planet?”

“It depends on the social circles,” he explains. “But the common human would probably be… shocked to find this scene.”

“And yet you seem perfectly at home,” he smirks. Then he gestures at the ocean dome above them and the slightly purpley moonlight streaming in. “Pelium is a mineral in the crust of the planet. It permeates everything and under the light of the moon it awakens our mating instincts. Very popular with other species, it’s our greatest export. On the full lunar we gather together to celebrate our wives, their fertility, and many who aren’t mated find companionship. Our adolescent cycle is much shorter than yours I believe so there’s always plenty of people looking for new mates.”

“Fascinating,” he murmurs, glancing down at Peter. “Sex and mating are generally more private for the common person on our planet.”

“Ah, but you are not a common man, Stark,” he chuckles. 

“Well, you got me there,” he laughs, raising his wine glass in a mock toast before taking a sip. “So are we talking full blown orgy?”

“I’m sorry that didn’t translate.”

“Ah. Group sex. Everyone stays here and mates.”

“Oh, I see,” he laughs with understanding. “It is optional. Hence why we gave you rooms. But yes it’s very common to stay and partake of each other in the company of friends. Things will devolve as the night goes on, but for now we eat and we drink.”

Tony looks down at Peter to see what he thinks of that, and his breath hitches at the expression on his face. He’s looking up at Tony like he’s a god, pure awe and devotion in his eye. It makes him feel heady and his cock starts to harden again. His balls still feel heavy and he’s sure the pelium in the air means he can go all night long. 

“What do you think of that, bambino, hmm?” he murmurs, petting his cheek with his knuckles. “You wanna stay here the whole night?”

Peter whimpers and shakes his head.

“No, you wanna go to our room, huh?” he coos. He nods, and Tony smiles. Whether it’s because Peter wanted privacy while Tony gave him relief or he just wanted this to be over, it didn’t matter. He thinks its the former, based on the way he’s still attached to his cock like a vice. “Okay, when it’s time. Shh, shh, just relax, tesoro.”

“You use strange words sometimes,” Halvin remarks. “They come through as sounds.”

“Mm, yeah it’s Italian,” he explains. “Another Terran language that’s regional. I grew up speaking it and I use the pet names on occasion.”

“How fascinating. Tell me more about this region.”

And oh Tony doesn’t need to be asked twice to chatter on about Italy. It’s a nice subject to pass the time though Haliven can not grasp the concept of pasta. It’s sort of hilarious actually. They seem to eat a mostly natural vegetation and fish diet here so he doesn’t blame them, but the fact that spaghetti is the thing they can’t comprehend is pretty funny. 

Peter is mostly content, though as the night goes on he starts getting more restless. Tony pulls him off his cock at some point, tucking himself back in. When Melica finally ends up in Haliven’s lap, Tony is glad because he wants to hold Peter desperately.

“You want to come up here, sweetheart?” he asks, hodling his hands out. 

He looks torn, biting down on his lower lip. “I- I don’t know if I can,” he whispers, his voice a little hoarse. “Physically.”

Tony looks at him in confusion. “I don’t give a damn if your dick is hard, Pete,” he murmurs. 

“It’s– ugh, okay,” he whimpers before getting to his feet. He sways slightly, looking a little dizzy. Tony puts his hands on his waist to steady him and gasps when his fingers almost touch. What the hell? Was he wearing a corset? Peter whimpers. “Do you hate it?”

“No, no, baby, I love it,” he whispers, pulling him into his lap. Peter straddles his thighs, wincing as he kneels down and arranging himself so his groin isn’t touching at all. “Are you hurt?”

“No, just– stop asking,” he hisses, cheeks pink with humiliation. “You’ll see later.”

Later. Oh fuck. Okay cool. Later was happening. 

“Don’t spoil their surprises, Tony,” Haliven chuckles. “I’m sure he’s been thoroughly dresssed up for your enjoyment under there.”

“He has,” Melica giggles. “He’s soooo pretty.”

Peter whimpers, eyes squeezing shut and clearly embarrassed. Tony rubs his hands up his thighs, making him moan. “He’s gorgeous,” he says, his voice a little more vulnerable and honest than he should probably allow. “My perfect boy.”

He sucks in sharply and then spasms again, letting out a pathetic little whimper. Seriously, it’s like he keeps cumming. Or more like he’s being deined cumming. Like something is preventing it from happening, no matter how much he wants it. 

They don’t make it twenty minutes before Peter is suddenly putting his hands over Tony’s and looking at him desperately. “Tony,” he whispers. “Please. I can’t– I need– I–”

“Oh, he’s gorgeous,” Haliven chuckles. “You’re in for a fun night, Stark, if he’s already begging. Go. Enjoy. I shall entertain your friends for a bit before I enjoy my Melica.”

“Uh-huh, yep, thanks Hal,” he says, helping Peter off his lap. He looks ready to explode. Tony takes his hand and the boy presses against his side tightly, going as far as to engage some of his sticky. 

“Wait,” he gasps raggedly in the hall. “Sorry, sorry, can we just– slow down a little–”

“Shit, sorry,” he winces, slowing his pace. “Do you need me to carry you?”

He shudders and then nods. “Please,” he croaks. “But like– princess style.”

“Of course, baby,” he murmurs, getting one arm around his shoulders and then gets his other arm under his thighs, lifting him up without any struggle. Peter violently twitches that time, winding his arms around Tony’s neck and clinging to him with a little sob. “Oh, Pete, what did they do to you? Why do you keep–”

“Cumming. I’m cumming, Tony, so just–” he gasps, burying his face in the crook of his neck as Tony walks. 

“Jesus Christ, okay,” he whispers, walking a little quicker. “You’re okay, baby. I’m right here. Gonna make it all better.”

“You’re gonna be mad,” he whimpers. “They did stuff– I should’ve stopped them but it sort of felt good and now we’re in this mess and oh god Tony, I’m so sorry you have to deal with this but I can’t do it by myself.”

“Shhh, calm down,” he soothes as he gets ine one of the elevator things. They work on hydro power. They’re really cool and he wants to tell Peter how they work but now isn’t the time. “Everyone does dumb shit in their twenties, baby boy. Letting a bunch of mermaid chicks on a sex planet use you like a Barbie doll is honestly not that bad.”

“You don’t have to keep calling me that, they’re not here,” he mumbles. 

“Calling you what?”

“Baby.”

“Do you not like it?” he frowns.

He whimpers. “I love it.”

Oh. For being a genius, Tony is really dumb sometimes. He’d thought Peter had grown out of his little hero crush but maybe he’d just gotten better at hiding it. No wonder he keeps going on about Tony being upset. 

“Listen to me,” he says softly, wanting to get this in his head before they get to the room and all hell breaks loose. “When this is over we’ll have a long talk about when I fell in love with you and pray it’s not too inappropriate, but I’m not doing this out of the goodness of my heart kid. I’m a selfish mentor who wants to pull you apart with my cock before putting you back together again. You got it?”

Peter lets out a wet laugh, nodding against his neck. “I love you, too,” he says, his voice thick with tears and arousal. 

“Oh bambino,” he sighs, kissing his shoulder because that’s all he can reach. “I don’t deserve you, kid, but I’ll pull the self-loathing card when you’re not ready to explode. Seriously, what did they do to you.”

“There were these pools and everyone was naked,” he mumbles. “And then I got in the water and– and I guess somehow it stops you from cumming. It lets you edge and you like twitch and stuff but you don’t actually finish. Except I think its starting to wear off and the spider– I can cum a good three times in a row on a normal day, this is–”

“Shh, okay,” he soothes as they finally reach his room and he bumps open the door with his shoulder. “I can work with edged your brains out.”

“I’m so embarrassed,” he whimpers.

“Good.”

Peter whines and lifts his head, looking at him in confusion. “What?”

“It’s hot when you’re embarrassed,” he shrugs, taking him over to the bed and gently laying him down. He moans softly and Tony is dying to get his hands on him. “What am I gonna find under here, Petey-pie?”

He laughs, almost delirious. “So much,” he moans.

Tony hums, eyes roaming over his slender body. He doesn’t understand how everything is seemingly hidden under the scrap of fabric they’re calling a dress. “I’m gonna kiss you,” he murmurs, putting one hand on the bed and then his knee so he’s hovering over him without touching. Then he drags one finger across the neckline of his dress. “Then I’m going to unwrap my baby boy and you’re going to tell me everything. Understand?”

“Yes,” he whimpers, tilting his head up a little.

“Yes, what?”

“Yes, Daddy.”

Tony groans and kisses him as promised. Peter’s ragged moan is the most beautiful sound he’s ever heard. He twitches again and Tony grins against his lips. “Good boy,” he praises, fully leaning into the experience. “Such a good boy cumming with a little kiss. Does it feel good, baby?”

“Yeah,” he moans breathily. “Thought about you everytime. Came when I heard your voice, when you fed me. Your cum tastes so good, daddy.”

“Yeah? Little spider needs his protein,” he teases, kissing him again. He tongue dips into the soft heat of his mouth and he groans. “Why are you so fucking wet and soft in your mouth? Is that standard? It doesn’t feel… human.”

“I don’t think so,” he pants. “Mel– she– she breastfed me? Um– it probably did things.”

Tony’s brain totally shorts out at the idea of Peter suckling at a girl’s tit, imagines his throat bobbing as he swallows down mouthfuls of milk. He kisses him heavily again, both of them monaing. “That’s so fucking hot,” he growls. “You were drooling so pretty for me, baby boy.”

“Ngh, Daddy, please,” he whines.

“Shh, shh, where should I start? Here?” he asks, reaching for the tie of the dress. 

“Yeah, yeah, there,” he nods, swallowing thickly. 

Tony unties the silk from around his neck and pulls it down his front. He groans when he sees hwo puffy and pink his nipples are, sticking out from his chest like little teats, dangling with gold hoops with pearls. His areola are puffy and soft and Tony wants to sink his teeth into them. 

“Are they healed?” he croaks.

“Yeah,” he whispers, sucking a sharp breath. “Everything is healed.”

“Everything?” he asks in disbelief. 

“You’ll get there,” he laughs, arching his chest up. 

Tony groans and gives in, wrapping his mouth around the puffy mounds. He sucks, flicking his tongue over the piercing. Peter shouts, hands flying to Tony’s hair to hold him there as he gasps and writhes. Tony puts a hand on his hip to pin him down best he can. Then he bites, worrying the soft flesh between his teeth and Peter sobs with pleasure.

“Daddy!” he sobs, clinging to him tightly. “Fuck– oh god. Oh my god, yes, more more more, Tony please–”

Tony grins and adjusts his grip, bitting him in a few spots before switching to the other side. He bites down before he even sucks this time, pressing the little hoop to the roof of his mouth with his tongue so it tugs. Peter thrashes and then sobs again, clearly having another mini (or not so mini) orgasm. 

“Good boy,” he soothes, smattering his chest with kisses. “God I can’t wait to get down there and see how much cum is between your thighs.”

Peter lets out a delirious laugh. “You might be disappointed.”

Tony tilts his head to the side, his eyes darkening as he runs his hand down his hip to his thigh and then starts to push up the skirt. “Will you let me see, bambino mio? Let me see what they did to you.”

More tears prickle in his eyes and he lets out a shuddering little breath. “It’s weird,” he whimpers, sounding ready to cry and not the fun kind.

“No, no, baby, it’s not weird,” he soothes, kissing him softly and petting his curls. Peter clings to him, breaking into sobs. “Shh, I promise I’m gonna love it. Daddy’s got every kink under the sun, sweetheart. Lemme see, okay? Just rip it off like a band-aid.”

“O-okay,” he hiccups. 

“We don’t have to do anything you don’t want to do,” he reminds him as he sits back on his knees and reaches for the skirt. He pushes it up and it takes him a second to even process what he’s seeing. When he’s done, his jaw drops, getting dizzy as all the blood rushes to his cock. “Oh my god, sweetheart, look at you.”

The first thing he sees is the bow, white ribbon wrapped around his boy’s cock like he’s a present. It’s holding him flat, attached to something else between his legs that Tony can’t see at the moment. The next is the string of pearls, artfully wrapped around his cock, and when he follows the trail, down, down, he sees that they go inside. His slit is flushed and drooling around it, creamy, white pre-cum smeared over everything. That only draws Tony’s attention to the fucking piercing in the tip. The gold bar has more pearls hanging off it, making it look like Peter is permanently dripping. 

“Jesus Christ, Peter,” he breathes out. Like he’s in a trance he reaches out and undoes the ribbon, moaning when his cock springs into the air, bobbing slightly. Peter’s cock is long and thing, but so, so gorgoues. He can see every pearl inside him, disappearing down his length and looking oh so touchable. 

His balls hang heavy between his thighs, another line of pearls running between them from his shaft. He grabs Peter’s legs and slowly moves him so his feet are braced. There’s a pearl the size of a strawberry nestled against his pernieum, attached to a string that leads into his tight little hole and tied off with the other end of the ribbon that had been holding him down. The outside of his rim and the inside of his thighs glisten, like he’s leaking lube.

“Can I touch?” he whispers. 

“Yeah, Daddy,” he whimpers, eyes blown out and panting. His tits are heaving, likely due to the white corset wrapped tightly around his middle that Tony has no intention of taking off. 

Gently he puts his hands on his thighs and gives him a squeeze before slowly moving up. He’s noticing now that all his body hair is gone, his legs and pubic bone soft and smooth. He reaches behind his legs and unties the second bow wrapped around the large pearl, tossing the ribbon to the side. Then he thinks better of it and grabs Peter’s wrists, tying them together with a big bow and gently putting them above his head, forcing him to stretch out and arch his back. 

“So you can’t try to hide any of this from me,” he murmurs and Peter whimpers. He reaches for his cock, wrapping his hand around his slender length and squeezing lightly. Peter moans, his back arching even more as he tries to fuck his cock into Tony’s hand. “Tell me.”

“They laid me out on this ledge and pinned me down,” he moans, staring down at Tony heatedly. “These girls are so strong, Tony, stronger than me. And they just– they swarmed me like I was a new toy. This one girl, Adrina, kept going off about pearls. She– she used this rod. It looked like coral, felt like coral, but it felt so good. And then she lubed up the pearls and they just– they just went in. I didn’t think they’d all fit but–”

“All?” he asks in curiosity, giving the string a little tug. Peter shouts, his whole body tensing and Tony freezes. “You okay?”

He squeezes his eyes shut, breathing heavily. “They– they’re in my bladder,” he whispers. 

Tony’s jaw drops, his cock gushing slightly. He feels ready to explode he can’t imagine how Peter feels. “Oh my god, baby. Did she tell–”

“Nope. No, they didn’t so let’s just– I’m okay. I’m fine, just… you take them out and I’m going to burst,” he laughs delirously. “I have to pee so bad. All the breastmilk… god, Daddy it was so much.”

“Did it taste good, bambino?” he murmurs heatedly, lightly storking his cock again. He’s sure to squeeze the outside line of pearls against the one inside, rubbing the sensitive skin between them. “Bet you looked so cute drinking it all down.”

“It tasted like– like a pina colada kinda,” he laughs. “It made me horny.”

“Everything is making you horny,” he chuckles. Then he taps the piercing on his tip, making him gasp. “This?”

“Mel’s idea,” he whimpers. “Had to talk me into it but… she said you’d like it.”

“Oh, I do,” he groans, rubbing his thumb against it. Peter twitches again and Tony knows he should be careful. It can’t be good for him to stay this blocked up for this long. “More pearls in your ass, baby?”

He whimpers, looking worried again. “M-my pussy, Daddy. They– they kept calling it–”

“Oh of course they did,” he coos, reaching down with his other hand to tease at his rim. “You’re just so sweet, baby, how could it be anything else? A pretty pussy and a perfect clit for Daddy.”

“They didn’t understand–” he swallows hard. “Why it wasn’t getting wet.”

He barks out a laugh. “I’m sure. Did they lube you up enough?”

“No, I mean yes, but– Daddy, they– they made me wet. They-put-slugs-in-me-and-it-turned-my-hole-into-a-pussy.”

Tony blinks, not sure if heard him right. “I’m sorry. Did you just say slugs?”

“Uh-huh,” he sniffles. “And some snail thing on my nipples. I told you it was weird!”

He stares down at his baby boy, looking at the pearl threatening to pop out of his ass. “That’s all natural lubricant dripping out?”

“Uh-huh. They cleaned out all the other stuff. I can– i can feel it every time I cum.”

“Holy fuck,” he whispers. He should think logically, take Peter to medical on the ship or something, but he’s the king of bad choices. He grabs hold of the string and tugs. Peter moans as his hole stretches around the bead and it pops out, shiny and dripping. 

He pulls again and again, watching in a trance as each pearl comes out with a little dribble of slick. Peter is crying, sweet, beautiful tears and Tony can’t help but keep teasing his cock, holding it in the warmth of his palm and playing with his piercing. 

“Look at you, sweetheart,” he murmurs. “Look how full this little pussy is, my goodness. You’re fuckin’ dripping, Pete. You’re gonna feel so good around my dick.”

Peter sobs, fingers twitching like he wants to cover himself up. “Please, Daddy,” he begs. “I need it so bad.”

“You want me to leave your clit full?” he asks teasingly, rubbing his thumb over the tip to play with the pearl poking out. “You want Daddy to fuck you while your bladder is full and you can’t empty out those little balls?”

“Yeah,” he nods pathetically. The last pearl slips free from his ass and he moans. Tony watches in deep aroused fascination as a gush of liquid runs out of him. “Oh my god.”

“Fuck, I hope that’s permanent,” he whispers, before pulling back to take off his clothes. He nearly tears the delicate material as he chucks his shirt and then pushes off his pants. He grabs Peter’s legs and pushes them up to his chest, making the boy squeal. Then without fanfare, he shoves his cock into his hole, feeling abosltuely feral. “Shit– oh my god, baby, that’s it.”

“Daddy, daddy, daddy, daddy,” Peter chants as Tony rocks him with every thrust. 

Tony fucks him hard and fast, knowing they both need it. His insides are as soft as the fabric he’d just been wearing, hot and dripping wet. Tony’s cock fits inside like a glove, pumping in and out of him, adding his pre-cum to the slick mess. It doesn’t last long, but it doesn’t need to. They’ve got all night.

“Fuck, fuck, I’m gonna cum, baby,” he moans. 

“Yeah, please,” he whines. “Fill me up, Daddy, please.”

He groans, his head falling back as he slams in balls deep, letting go as his cock throbs. He breathes heavily as rope after rope shoots into Peter’s ass. Peter goes quiet, whimpering and moaning, but seemingly settled. 

“Good boy,” Tony finally breathes out, gently lowering his legs. “So sweet for Daddy, baby. You okay?”

“Uh-huh,” he nods, his eyes glassy again. “I think– I think I really need the front ones out though.”

“Yeah, I agree,” he murmurs. He slowly pulls his cock out, both of them sighing at the action. He sits down, pulling Peter a little closer by the legs so he can work, getting his hips practically in his lap. He unwraps the pearls from the base of his cock, holding on tightly to the little string so he doesn’t lose it. “I’m gonna go slow, okay? I don’t want to hurt you.”

“Okay,” he whimpers. Then his eyes well with tears again. “I’m not– I won’t be able to hold it.”

“I know, that’s okay,” he soothes, rubbing one hand over his corset where his swollen bladder sits beneath. “I don’t want you to. Just stay nice and soft for Daddy. Trust me.”

He swallows thicky but nods, taking a shaky breath and melting into the sheets. Tony murmurs a soft praise before grabbing hold of his cock with his other hand to hold him steady. He gently tugs, testing the resistance and is pleased to see that the pearls glide out easily. Peter moans and Tony braces his thumb aganist the underside of his length a little better so he can feel them coming out.

“You’re gonna feel so good, bambino,” he murmurs as he slowly pulls. His cock is already rock hard again. Pearl after pearl pops out and when Peter gives a little gasp, he knows the one in his bladder are moving. “Shhh, that’s it. Give it all to Daddy. You’re being so good.”

“It feels– oh god–” he moans, his head listing to the side. His curls fall against the mattress, a little damp and sweaty. He looks like a painting and Tony wants to save this moment forever. “Don’t stop, Daddy, please.”

“I’m not gonna stop,” he assures him, rubbing his thumb back and forth a little. He has to readjust his grip as the pearls pool in his lap. They just don’t stop coming. “Oh, you’re so full, baby boy. It’s gonna feel so good to be empty.”

“Mhmm,” he whimpers. Then he looks at Tony, biting down on his lower lip a little. “Then Daddy will fill me back up?”

He grins, bending down and pressing a kiss to the tip of his cock and making him gasp. “Daddy will fill every one of your little holes if you want, sweetheart. But only after you’re empty.”

“Kay,” he whines, head titlings back. “Love you.”

“I love you, too, Pete,” he sighs happily. “So much.”

He keeps pulling and the pearls keep coming. The strand has to be at least two feet, and Tony swears there must be magic or something happening because Peter is sturdy but this is insane. When Peter’s eyes go wide and he gasps sharply, Tony knows he’s almost at the end. “Daddy, daddy—“ he gaps, panicked. “I’m gonna—“

“Yeah, here it comes, bambino,” he soothes, feeling the last bead against his thumb. “Just let go. Make a mess for daddy, sweetheart, it’s okay.”

The last pearl pops free and Peter screams loudly, his back arching off the bed. All things considered, it’s not the fountain effect that Tony expected. Instead, Peter’s cock throbs in his hand and then squirts a cute little inch into the air before drooling. It’s a rush of liquid, cum and piss, but god it’s sexy. His hole is so open and watching everything leak out of it is addicting. He wants to keep this boy drooling forever.

“Oh god, oh god, oh god,” Peter babbles, gasping and heaving. 

“Good boy,” Tony croons, lightly jerking his cock to get everything out. His cute little balls are pulsing and Tony cups them with his other hand, feeling how heavy they still are. “That’s my messy boy. Let it all go, baby, that’s it.”

Peter whines, tensing up as the cum keeps pulsing out before finally slumping. His eyes flutter shut, sucking in sharp breaths of air. “Oh,” he whines weakly and then starts to laugh. “Wow.”

Tony laughs as well, still rubbing his cock and squeezing his balls in an almost soothing touch. “Feel better, baby?”

“Yeah,” he sighs softly. “Mmm, still horny somehow.”

“I think it’s impossible not to be in this place,” he chuckles. Then he smirks, rubbing his thumb over his gaping tip and making Peter whine. “You want a break?”

“No,” he moans, his hips bucking. “Don’t stop.”

“Alright, sweetheart,” he chuckles, leaning down to kiss him softly. “I won’t stop until morning.”

★★★★★

“Thank you again for everything,” Tony says, shaking Haliven’s hand. “We’ve had a wonderful time.”

“Of course, Tony! You and your wife are welcome anytime.” 

Tony and Peter look at each other with the same expression. They’d be back, but maybe not for a while. Turns out one night on Peleca Four was twice as long as an Earth night. Even Tony, ever the hedonist, had finally had to call it quits and pass out with his boy before the sun ever rose. 

“We’ll keep in touch,” he chuckles. 

Peter leans into his side as they walk into the ship, then suddenly lets out a soft giggle. 

“What?” Tony asks with a little laugh.

“I was just thinking,” he giggles. “This would’ve been a wild Star Trek episode.”
