Teeth

Summary:

Grace makes out with Simone after a few drinks on her birthday and wakes up to few new mutations of her own.

Notes:

This is my second smut fic ever and the first was really fun so trying out some omegaverse!

(See the end of the work for more notes.)

Work Text:

Grace sits hunched over a microscope, glasses pushed back on her head, cane at her side. She’s not quite sure why she even has them. Her near sightedness had been cured two days ago. And she’d been able to stand without pain for the first time in years.

Last week was so completely normal and now… apparently she was spider man. Minus the muscles, those sadly had disappeared after a good year of two of starvation.

Last week she and Simone had recreated alcohol. It was an awful kind of wine made from a hybrid Eridian plant, modified for human consumption. She and Simone had made it their joint pet project after the teeth started growing in. She didn’t talk about how she felt often and instead buried herself in work. So, Grace said her job was to party with her for her unofficial thirty something-ith birthday. She had been so quiet lately, Grace thought getting hammered on the beach might put her in a better mood. They'd even made little ceramic “shot glasses” to mark the occasion.

They’d sat on the beach, fake moon glinting off the pitch black waves and it wasn’t even a conscious thought really. Simone looked nice, Grace was buzzed and relaxed, they were laughing. So she leaned in and brushed a kiss to Simone’s cheek. And maybe because Simone was also buzzed and relaxed and not thinking, she leaned in and kissed her in full.

Grace flushed as the memory of Simone’s tongue slipping between her lips tried to creep in. Grace had gotten to run her own tongue over the sharp fangs in the back of Simone’s mouth. When she pulled away Simone’s mouth had been covered in blood. Grace had to lean back for a second and rub her eyes.

Maybe that’s why she’s been avoiding her.

The blood sample on her slide pulsed under the refracted light.

Two days ago her body decided to completely freak out and induce cramps that felt like they were shredding her from the inside out after a week of what she thought was the flu. It started like period pain, but a few hours later she found herself unable to move. She’d thrown up twice, screaming in agony before blacking out. The fever was still raging but muscle aches and fatigue had been replaced by overwhelming new urges.

The spark notes version was that she wanted to have sex with Simone, which wasn't new. What was new was that she wanted to leave teeth marks all over her body. She wanted Simone’s claws to draw bloody lines across her back and shoulders. She wanted to fuck her while she did it. She wanted to watch come drip out of her pussy after she’d used her like a doll. Which she might be able to do given recent developments.

This last one made Grace feel a little twisted but she wanted to get her pregnant. To watch her stomach swell with her- seed?

Seed??? What the actual fuck this isn’t Game of Thrones!?

Grace sighed as she shucked her sweat soaked shirt off and face planted into her bed. She can feel the ever-present pressure building just from the contact to her bare breasts. She groaned as her hips rolled slightly into the mattress. That was a thought that had never once crossed her mind before now, what the hell is wrong with her??? The violence of the fantasy scared her way more than the sickness. Or whatever was happening between her legs. She didn’t want to hurt her, she didn’t even like stuff like that, she would NEVER!

At the same time though, Grace found she wanted to dote on her. The new possessive part of her brain wanted to own her ,yes, but part of that ownership included caring for her as best as possible. Grace would absolutely never tell her this but she lived to do things for Simone. She lived to help tie up her hair, make dinner for her, clean the house, wash her clothes. She still carried things for her despite Simone being able to lift Rocky over her head like he wasn't over 300 pounds. A selfish part of her missed dressing her wounds or helping her bathe. That part felt a lot more normal to her, it’s how she’s been in all her other relationships on earth.

Except they weren’t in a relationship and Grace needs to get a grip.

The lab results showed elevated hormone production but no concrete results as to what was happening. Grace wanted Simone to ask her to do all these things to her. She wanted Simone to do all these things to her in turn. To claim her like a prize, and fuck her like she was her bitch. Could she?

Grace had never examined anything below the belt mutations wise, if anything like this was happening to Simone she might?

She knows Simone has something to do with it. Or rather the parasite that’s infected her. It’s the only half -cocked theory she has other than a full blown mental break. Whatever’s happening is completely and quickly getting out of her control, overriding rational thought and leaving only the base impulses.

Eat.

When Simone first got to Erid, she was down an eye, an arm, and a good chunk of skin mostly on the left side. Trying to Frankenstein her back together was terrifying given Grace had almost zero medical equipment outside of Armando. But at least predictable. The corrosive battery acid like skin damage and severed arteries were something she could look up on her computer. But the growth…?

It started with the skin around her left eye two months after she first regained consciousness. What should have turned into scar tissue similar to the burns on Grace's arm smoothed out into pale but otherwise perfect new skin. Then a month after that Simone had casually walked into the kitchen after her first night in her new room with an entirely new eyeball in what had been a previously empty socket. So far as they could tell it was fully functional but not quite human, with no visible pupil. Completely black. Like a fish.

At month four Simone had quietly told Grace how she had gotten hurt. Grace had held her shaking hand as she explained why she was there. What she did. Grace couldn’t find it in herself to be scared of Simone though. Maybe a little off put at first, but it was hard to judge someone from another dystopian reality. Riley gathered that whatever organism inhabited the “blood moon” had formed a mostly symbiotic relationship with its new “host”.

At first it was just repairing major damage albeit with imperfections. The regenerated arm ,again, was technically functional, but was slightly too long, covered in pale skin and had barbed claws instead of fingernails. That one had been a little scary. At month five Simone woke up complaining about itching and pain in her arm stump. Grace had almost gagged when she removed the stumps bandages to find the stitches broken and the end of a new bone sticking out of the flesh. The itching had been from the surviving skin breaking apart as new tentacle-like muscle fibers and raw nerve endings extended outward.

 

Simone flinched whenever Grace touched it. She said it didn’t have much feeling, like when you fall asleep in a weird position. Grace was somewhere between insanely curious, excited, and horrified. Excited because her new friend WASN'T dying, horrified because she didn’t know exactly how. She enjoyed Simone’s company once she finally relaxed. She was kinda bitchy but smart, good with tools sort of like Rocky. They’d gotten along rather well after Rocky convinced her he wasn’t going to try and eat her.

But Simone should’ve died, not even a qualified surgeon would’ve been able to save her when she was pulled out of the sub. Based on what Simone told her, she’d swallowed enough acid-blood-whatever to melt her stomach lining. So this stuff would have had to have damaged and then restructured some of her internal organs. Which was concerning enough on its own without Simone’s teeth falling out.

At month six Simone bit down on a me burger and three of her front teeth got lodged in her food. She and Grace had stared for a long moment before Simone simply pushed her plate aside, and rested her forehead on the table in defeat. Grace had placed a hand between her shoulders but could only watch helplessly as Simone started to cry. The rest of her teeth followed by the end of the week.

Grace had spotted her poking her bleeding gums in the mirror a couple of times. She got frustrated trying to speak after that and would start crying again when she couldn’t pronounce a word right. Her new teeth seemed to stress her out even worse. This new set was completely serrated, with two sets of elongated canines on each row. Several more had sprouted from her upper and lower gums like a shark. They grew right back no matter how many times they were pulled out.

She’d started shutting herself in her room a few weeks back. Rocky had tried giving her new projects like the green house, which she loved, but she still would retreat back to the room the second they were done for the day. She hadn't spoken to Grace at all since the beach incident. The last time Grace had caught a glimpse of her coming back from the greenhouse, she looked awful. Tired and extremely pale. Sweating like she had just run a mile.

Simone has no idea how to handle… this. The arm and the weird shit had been one thing. It was hideous and she wanted it all ripped off but that was sort of manageable. This mutation just made her want to die. Of all the things to change, why this???

A lot of her new adaptations are incredibly uncomfortable. Everything is too loud. Her zombie arm had muscle spasms that knocked things over. Her freakish teeth would slice her lips open constantly. She had… openings now along her ribs? Not mouths but skin flaps that fluttered when she breathed. They whistled slightly and felt cold. Her throat rumbled more so she might have more vocal cords??? She hated it. Her face she could deal with but her voice was too much. She looked and sounded disgusting even if Grace was too polite to say it.

She felt horrible avoiding her. Grace had leaned over and kissed her on the left side. She always sat to the left of her, leaned into her pale shoulder more often than not. She tasted like alcohol and iron. Her lips had been torn to shreds, Simone had forgotten little nips did a lot more damage when you had serrated teeth. Simone sighed at the moonlit memory all the same. The blood had painted Grace’s lips a dark cherry red, and Simone had left little lipstick like stains all over her neck. They stayed a little even after a shower the next day.

This was simultaneously the worst she had ever felt and the most worked up she had ever been. She has no idea how to bring this up without sounding really weird either.

“Hey Grace, fun new thing! I can’t look at you or I’ll get horny and cry! Cause I wanna fuck but I can’t look in the mirror anymore either. Wanna make out some more?”

Wanting to fuck Grace wasn’t really that weird. She was nearly six feet tall and stunning. It had more to do with the unnatural intensity of the feeling and the sickening new bodily reaction and the raging fever. Because of course Simone’s personal anatomy had started warping with the rest of her.

If Grace stood close enough for too long she started thinking about insane shit. The human part of her brain wanted to fuck Grace, like a normal person. The mutated part wanted Grace to destroy her. Like a fucking animal. It didn’t even make sense, because of course she didn't. Grace didn’t seem the type to be rough anyway. But it sort of did in the sense that she was sort of a … fish thing now. Animals had mating seasons. The rational part of her absolutely hated the thought of that. The other screamed at her to go find Grace and get to “multiplying “.

If it was the residual consciousness of the eel then this made horrific sense. The blood ocean was a hive. Its goal had been to grow by absorbing humans. Possibly because it had nothing else. But now its new form, in its new host, well fed and fully recovered, it could reproduce in the traditional way.

The thought made her stomach turn.

Her clit had pretty much stayed swollen the past week but around Grace things sort of opened? It was like her pussy would just instantly relax and the pressure of the teeth would disappear. She had to leave the room a few times because the second this happened she’d get insanely wet. Several pairs of pants were soaked like she’d spilled something in her lap. It felt so gross.

The stuff between her legs still looked female, clitoris and labia all unchanged. But her pussy had little barbs lining the inside of it now. She’d tried slipping a finger in to relieve herself and it came out shredded and bloody. The teeth had clamped down with a horrifying amount of force. Trying to get herself off with just her clit wasn’t working either. No matter how many times she tried to make herself come, the burning in her gut never stopped. Deep down she knows what will. Rationally she knows she can’t ask that of her. But the rationale is slowly slipping away as simpler things settle into the forefront of her mind.
Eat.
Sleep.
Fuck.
Repeat.

Simone is sitting on a table in the lab. Because of course she is! Grace wants to try and take more blood samples to figure this out and the problem is sitting there in tight shorts with no bra in one of Grace’s shirts. Her irritation falters once their eyes meet. She looks exhausted, jaw set as she grips the table's edge. She looks as feverish as Grace feels.

Simone’s human eye is blown like she's drifting away. Grace can smell her. She doesn't know how or why and she should be panicked by the fact that she can’t speak. But Simone smells like sugar and blood and salt and skin and sweat. And all that was running through Grace’s head was.

Eat.

Sleep.

Reproduce.

Grace feels like she's just taken something too strong. Looking at Simone feels like the time she ate too many edibles in college and knew the second the high set in that she was screwed.

Eat.
She's moving towards the table.

Sleep.
Simone has the smell of fertilizer slightly stuck in her hair.

Reproduce.
Simone has hooked a claw in the loop of her jeans.

She tilted her head to the side a little, eyes locked on Simone. Fear and intense arousal curling into one in her lower abdomen.

What’s happening?

Simone just tilts her head the same way, breathing a little too hard.

I don’t know.

Simone tugs her closer anyway.

She was making this noise in the back of her throat. It sounded like something between a growl and a purr. Grace felt the same thing move up from somewhere in her chest in response. Their faces weren’t more than an inch apart.

“You're different too.” Simone whispered. She sounds frightened. Grace nods. She’s frightened too at the lack of control but, nothing that’s happening feels all that bad. She likes Simone. All she wants at the moment is to make her feel good. Grace would, is, okay with them being intimate. Nervous maybe that it’s happening this way but fighting it just seems to make things worse. She tries to think through the hormonal fog that was clouding her judgement. They can't just-go at it. Simone is tense and scared. Grace is unsettled by it even in an altered state. She clears her through and focuses on producing words, like a person.

“I-I would…like to have…sex…with you.” It felt horribly awkward. But Simone smiles just a little.

“I know. I can, uhh, smell it. If that makes any sense?” Grace swallows hard. “You sure that's what you want?”

“Yes,” they were barely whispering, “what do you want?” Simone searches Grace’s face carefully before she answers.

“I would also like to have sex, with you.” She's hesitant.

“Do you want… this ? Is this ok?” Grace hates to see her so distraught.

“I… think so? Idon’t k-know what’s going on-It’s all so blurry and-! I’m sorry-” She looks close to tears but she hasn’t let go. Something about her distress makes Grace want to die.

“Neither do I but. Simone,” Grace really doesn't want her to even think about it , “I will lock myself in my room, this second, if you don’t like this.” Simone closes her eyes for a second and casts her gaze to her lap.

“…it’s not that I don’t. I don’t. Know exactly what will happen. “ Grace hums in understanding. It barely registers above the purring.

“Can you look at me?” Simone does reluctantly. Grace doesn't blink. “Do you want to hurt me?” She never had, even when she’d first woken up and threatened it out of fear. Simone could, easily, and in any number of ways. She had abnormal physical strength. She's shaking her head before Grace even finished the sentence though.

“No! Grace-“

“Ok. Then you won’t.” Grace was absolutely certain of that. Simone was so stubborn her will didn’t even bend to an angry God. “Do you think I would hurt you?” Simone looked taken aback a little.

“What - NO no! That's not-!”

“Sorry, I just. I need you to understand. I will not do anything you don’t like, because I do not want to hurt you. Physically or otherwise. Ok?” Simone nods.

“Ok.”

“And you would do the same for me?”

“Of fucking course!” Grace never doubted that was the case.

“Good. Now. Ignoring this has just made it worse, right?”

“Way worse.”

“So maybe if we just give in to what we want it’ll stop. So, what do you want?” Simone takes a deep breath and says it slowly.

“ I want you to fuck me, but…” Grace puts her hands on Simone’s knees.

“But..?”

“We-You kissed me. Was that before this?” Grace's face scrunches in mild confusion. Simone swallows and a tear slips out. “Did you kiss me because of this?” It was Grace’s turn to look startled.

“No! No, babe, no. I just,” Grace shrugged, “wanted to.”

“…Why…?”

Grace wasn’t completely unaware of how Simone viewed herself. But this. This hurt.

“Because,” Grace’s left hand rose to thumb away her tears,” I’m a scientist who studies aliens, and a very hot alien was laughing at my jokes.” Simone cringed then dissolved into exasperated laughter. “So to answer your question, yes, I thought you were very sexy and smart before this.” Simone huffed through her nose and her shoulders slump down in defeat. “And that your boobs were great-“

“Grace-“

“-and that your ass was so big ~!“ Grace can’t keep it together.

“-you are so not funny-“ but neither can Simone.

“Ok ok BUT. The point is. Whatever is happening, I’m okay with it. If it’s okay with you, I’d like to have sex. Preferably, a lot of it. What do you say?” Simone sighs but she’s blushing all the same. Grace rubs light circles into Simone’s knee with her thumb, while her other hand cradles Simone’s face. Simone’s purrs deepen and she leans into her palm.

“ I say you have weird ass taste.”, Simone mumbles. Grace grins and deadpans,

“Oh yeah, I’m so strange for wanting to bang a super buff lady who literally fell out of the sky.” Simone smiles despite herself and Grace feels a rush of relief.

“You can definitely try,” holy shit, “but I’m not sure you even can, anymore.”, she says without humor. Grace tilts her head in confusion, yet again. Simone moves to stand and hook her thumb into the waistband of her shorts.

Simone was leaning back on her hands on top of the table with her knees drawn up. Her face feels numb and the base of her skull is buzzing. The sweet sound of the synchronized purring mixed with their heartbeats is so soothing. Grace is sitting on a chair staring between her tensed inner thighs. Simone had said she was uncomfortable. Grace had said the same thing. So Grace had naturally said she would examine her. And afterwards they would come up with a treatment plan. Just like for all of her other mutations. Simone thought Riley’s attempt at foreplay to ease into, whatever was going to happen, was cute.

She can’t remember what had seemed so scary a few minutes ago. Simone simply had a new mutation for Grace to study. At first everything looks normal. Besides the fact that Simone was very obviously turned on. Everything was so damp Simone’s thick black hair was slicked down around the lips. Simone’s clit looked uncomfortably swollen along with her labia.

Riley can fix that. It's the only clear thought she has at the moment. Simone watched as Grace’s eyes trailed down to Simone’s cunt. It flutters and drips clear fluid onto the table.

That's when she saw Riley notice the sharp new set of teeth glinting from within.

Grace looked drunk, mentally heavy and slow, while her body thrums with energy. Without warning , her finger tip traced around the edge of the entrance. As if on cue Simone’s vaginal opening spasms and relaxes enough for Grace to get a better view of the white shark-like teeth that lined the inside and more liquid dribbled out. Simone squirmed.

“Does that hurt?”

“U-um no. You touching it doesn't hurt.” Sort of. It actually feels so good it almost does hurt.

“But you can’t get anything in?”

“I tried and it- bit me.” Grace swiped her thumb over the opening, gathering slick on the pad of her finger. Simone watched a string of clear fluid stretch between them as Grace brought her thumb up to her mouth. She felt a small gasp escape her and her cunt flexed a little wider. “What’s it look like?” Grace pops her thumb out of her mouth and creases her brows in thought.

“More like mailable cartilage than traditional teeth really…”, she looks up at Simone and raises a brow slightly.

“Mind if I try?” Simone purses her lips.

“You lose a finger, don't say I didn’t warn you.”
Grace hums before slowly pushing the tip of her middle finger into the mess and Simone braces for pain. But the hole instead seemed to instantly relax, sharp barbs feeling more like little bumps.

“Interesting. Retractable teeth.” Grace giggles at the sensation as she reaches farther to feel around the inner walls to see how far back the growths extended. Her finger curled up, and Simone's legs fell open a little more.

“Doing ok?” It was like the tension had disappeared from her frame. Her pussy was still leaking heavily. She was staring down at Grace's hand.

“Mhm.” It was barely audible. Something is happening. She feels…

“Simone?” Grace goes to take her hand out and Simone tightens. The teeth latched on the second she tried to pull back.

Grace purrs louder.

Riley brings her other hand up and spreads her lips further to the side to see how the teeth hooked into the flesh. It made perfect sense, the haze made everything clear. She doesn't want to just get off. She's in heat. She needs to mate. Grace could do that for her. She just needs to relax. Grace smiles and pushes in deeper like she can read her mind.

This was good. She’d need to be open for later. She doesn't specifically know for what.

A little spurt of liquid actually comes out this time and Simone whimpers but the purring never stops.

There's so much slick it’s like she wet herself on the table. Simone vaguely remembers her shorts being almost soggy when Grace helped take them off. She seems to be contemplating something from her little “doctor” chair as she slips a second finger inside without resistance. Simone groans.

“This explains it…”, Grace murmured.

“What?” Grace kept her eyes on Simone’s pussy as her fingers slowly scissored open and closed. It sounded like her fingers were swirling in water.

“I look different too. I think that’s what the teeth are for.” Oh Simone’s purring turns to high little trills. She wants to see! Simone’s body seems to just know what that means already. She wants to see how Grace has changed to fit inside her. Riley’s purrs drop into something a little deeper. She slips a third finger inside before she leans forward with her tongue lolling out. Simone whines as Grace slowly curls her fingers in and out while she lazily licks a line up her clit.

Grace moans before suctioning her lips right around the head of Simone’s clit and full on sucking the clit into her mouth.

“AAHhh-fuuuck Riley~!”

Simone’s nipples protrude from the thin fabric of the shirt she's still wearing. She’d take it off but her arms are shaking with the effort of keeping herself propped up to watch this.

Grace pops off of her clit to lap at the slick clinging to her inner thighs as her fingers thrust into Simone’s pussy harder. Simone’s head falls back as an ungodly amount of wetness keeps pooling between them. It feels so good, like Grace is massaging away a knot inside her. Instead of tensing at the pleasure her body seems to be going limp. Not a care in the fucking world.

She only jolts a little when Grace's attention returns to her clit.

“Mmmm, that's right baby.” Simone muttered, curved claws running over Grace's scalp,“You love eating my pussy don't you? So eager…” Grace moans but otherwise pays her no attention as her lips and tongue add drool to her already drenched pussy. The sounds remind her of someone sucking on candy. Simone giggled a little at the idea and Grace’s tongue pressed down harder. Her head fell forward again to watch with half lidded eyes as slick coated Grace's mouth and chin. It felt euphoric.

God she tastes amazing. Whatever is leaking out of Simone lights up some receptor in her brain and it just- she tastes soooo good. The iron and salt smell of it is filling up the room. This is so much better. Grace can't remember why but Simone had been so upset. That wasn’t acceptable. Simone was beautiful. Simone was hers. She should only feel good. Or Grace could fuck her until she did.

Grace has four fingers and her thumb working inside her now and Simone is mewling. She’s almost ready. Once she can get her pussy stretched they’ll go back to her room. The lab table will hurt Simone’s back.

“Deep breaths baby. Don't tense up. Stay nice and relaxed for me, you're almost there.”

“Grace, it feels so tight, b-be gentle please!”

“I know, you're doing so well though. Any pain?”

“No, it’s just a lot. I’m ok. Just go slow.”

Grace pushed in experimentally. Simone is shaking. Sweat was dripping down from everywhere, making the white shirt cling to her skin. Her tits and muscles were outlined perfectly, dark areolas just teasing being visible, hair sticking to her face as she breathed deep. Grace had almost managed to slip her entire hand inside. This would be bigger than what she needed to take but Grace was enamored with how much Simone’s body can actually accommodate. Abnormally strong muscle envelops her and Grace licks her lips as she watches her wrist disappear inside her pussy. Grace still has to force her own hips not to roll into the sensation as Simone cries out.

“Oh my god Simone, you look gorgeous baby. Your pussy looks so perfect. Doing so good for me.” Grace leans forward to press a kiss to Simone’s clit before pulling her flattened tongue over it. Simone sounds pained and her barbed pussy squeezes around Grace’s wrist, teeth poking lightly.

“Sorry- ah-!” Grace starts slowly curling her hand into a fist while her tongue gently plays with Simone’s clit. The position is a little awkward but Simone loosens up again.

“Better?” Simone just nods, completely focused now. If she does get tense like the barbs might slit Grace's wrist. That should be concerning but instead Grace feels a little spike of irritation that Simone won’t let herself relax all the way.Grace moves forward and feels her knuckles hit Simone’s cervix. Simone lets out another trill that layers over her moans. Grace feels her own pussy dripping and pulsing in response to that noise.

“Riley fuuck-“, Simone’s voice is pitched high with strain and warped by the trilling, “ ah baaaby please-!” The squelching of her tight, perfect cunt is hypnotic. Riley’s tongue has found the best pattern to make her squirm and she focuses on keeping it in time with the movement of her fist.

“Rillleyyy- fuck- plEeeAAASE please p-pleaaseee please-!” Simone’s pussy started to tighten again at the overwhelm. Grace feels the teeth dig in a little deeper this time. It should hurt but Simone is pulling her hair and she feels so good, shes going to come, and that’s all Grace wants, is for her to feel fucking amazing. She lets up on Simone’s clit for a split second to suck in air and Simone tugs her head back by her hair. Grace keens at the prickle in her scalp.

“What-“

“Grace stop! Can you not feel that!? ” Grace looked down and saw blood mixing in with the slick. Her hand was getting sliced. She can’t give a single fuck and stares up at Simone as they both pant.

“You were close?”

“Y-yes but-“

“Let me keep going then.” Simone’s face screws up , conflicted, trilling low.

“You're sure?” Grace doesn't bother to answer, tongue dipping immediately back to Simone’s clit and arm pumping in and out again. Simone’s pussy is fluttering now, blood and fluid squeezing out around Grace’s wrist. Each time she contracts the teeth catch on Grace’s hand and attempt to sink in like fish hooks to hold her there. It should feel like a meat grinder, but Grace realizes she has very little feeling in her arm at all now. Or her lips. Oooo! Neurotoxin!

Grace is actually so excited at the prospect of studying the numbing agent that she almost forgets what she’s doing to reach for a swab. Simone is actively ripping some of her hair out and it's getting really hard to move her arm the closer Simone gets.

“Grace- Riley please fuck wait aaAAAaAh ah ah aaahh- Fuuuuck, oh fuck-!” Grace lifts her head up and brings her free hand to make slow movements over Simone’s clit while her fist keeps moving.

“I told you to relax.”

“F-fuck you I ammm-!”

“No. I will not fuck you until you relax. All the way.”

“Your fucking bleeding already I-I Dont- ahhh -Riley please !”

“It doesn't hurt. You're not hurting me. So lay back and do what I told you.”

Simone snarls under her breath but lets go of Grace's hair. She takes the opportunity to finally strip off her shirt and Grace falters. Simone’s tits literally have beads of sweat running between them and they move with her chest as it heaves. The stupid little back brace harness is framing them perfectly. Every scar, beauty mark, and vein is on full display. And four new sets of gills, weeping clear fluid, flare on either side of her lower ribs.

Simone doesn't lay down. Grace stares as her right hand slides over her stomach to feel where Grace’s hand is sitting. Simone’s dark eyes roam over her before bringing her hand up to one of her lower gill plates.

“Fuck you. Put your mouth back on me and keep going. “ She doesn't sound even remotely human. Grace trilled as Simone’s fingers slid inside the gill cavity. She pushed deep enough inside that more fluid dribbled around her fingers and dripped down her hip. Grace felt her clit swell almost painfully just as Simone’s pussy squeezed around her arm again. Simone whimpers and takes her glistening hand out to start playing with one of her huge tits, both eyes completely black, fangs glinting from beneath her parted lips.

She dives back to Simone’s clit without another word. Simone’s hips squirm up as her arm starts moving again, faster now. The moans are warped as she switches between mewling and trilling loudly.

“AH-ahhh fuck, y-yes! Yes yes yes baby ooooh-!” Simone throws her head back as animalistic noises replace her moans. “Ooohhh god GrACE FUCK- oh my god YES!!! FUCK Riley pleaselpeaseohmygodpleaseeee-!” Grace cannot breathe, but Simone is so close. She drives her fist up harder, hard enough to hurt a normal person. “Ohmygod IM- yesss FUCK I can’t-yesyeSsYEsYES OH MY- AH-RILEY-!!!” Simone’s pussy spasms and clamps down so hard Grace feels a bone in her wrist crunch the same time as scalding liquid squirted around her arm and sprayed her neck. Simone is crying and shaking as she continues to spasm like that over and over, legs weakly trying to close, come drenching Grace’s chest and spilling off the table's edge.

Notes:

Leave a comment if you want part two, I love inspo/suggestions while I write the second chapter (some of you are freakier than me)
