One day in Titans Tower, when Robin was fifteen and Beast Boy was fourteen, Beast Boy noticed Robin in the communal shower for the first time. They had showered together often, but this was the first time that Beast Boy had forgotten the unspoken rule and made the mistake of throwing a casual glance in Robin's direction.
Beast Boy saw soap suds flowing down a flawless athletic body. Robin wore only his mask in the shower. The soap was running down a flat belly and an 8-inch flaccid penis.
Robin had a confident smirk as he showered. He was fully aware that his teammates would sometimes look at him, and he was comfortable with his nudity and had an adolescent pride in his penis. It amused him how much his size shocked people, though he always pretended not to notice. He was aware of Beast Boy looking, but casually avoided eye contact.
Beast Boy immediately looked away and shivered. His own 3-inch flaccid penis shriveled and Beast Boy's green face paled. He covered his face with his hands and did his best not to let his jealousy show.
Beast Boy let out a little sob while Robin whistled casually and wrapped a towel around his waist.
As soon as Robin was out of the room, Beast Boy transformed into a hummingbird and zipped down the hallways of Titans Tower, going straight to his bedroom.
Beast Boy flopped face-first into his bed and lay there naked. He groaned into a pillow and tried to get the image of Robin's huge penis out of his mind. He did not come out for the rest of the day.
The next day, life went mostly back to normal. Beast Boy fought a villain with the rest of the Titans, and it felt great as always, but when it was all over and the other Titans were relaxing, Beast Boy went to his room.
He opened his private journal and wrote, "Dear Diary, I'm sorry I haven't written anything for six months, but now I need to talk about something, and I can't talk about it with anyone else. I just measured my penis and it is 3.1 inches when it is soft. I know that's not a very superheroic size. I wish I could know what it's like to have a really big one that swings around and smacks against my legs when I walk."
Beast Boy drew a crude picture of himself with a huge penis, and then closed his journal with a deep sigh.
The next day he wrote, "Dear Diary, it's still 3.1 inches. I wonder if it will ever get any bigger. Also, Raven has been giving me some strange looks. I hope she's not doing some spooky mind-reading stuff, because I absolutely do not want her to know what I'm thinking. This is just between you and me."
He continued to write in his journal every day, and days turned to months.
"Dear Diary, I had a dream about Raven seeing my penis, except it was huge. She's usually so cool and emotionless, but when she saw that, she screamed in surprise and blushed bright red. She was like, Beast Boy, what even is that thing? And I was like, it's just my thing, Raven, no big deal. But it was a big deal, and we both knew it. She just kept staring at it in shock and amazement, and it felt so good. I made such a big mess in my sheets. But yeah, in real life it's still 3.1 inches."
More months passed and Beast Boy turned fifteen, and shortly later he wrote, "It finally happened. I checked several times and there's no doubt about it. I am now 3.2 inches. I'm fully across that line, and I have never been happier. Raven is giving me weird looks again, and I almost want to tell her so I can have someone to celebrate with. Obviously that's not going to happen. Raven wouldn't read a guy's mind without permission, would she?"
For the next year, Beast Boy filled the pages of his journal with elaborate stories where he was a nude wild man from the jungle with an enormous penis, and Raven was a demon princess. They had many strange adventures, but in every story she was always drawn to him by the size of his penis.
By the time he turned sixteen, his penis was 3.5 inches.
"Dear Diary, I know it's bigger now than when I started measuring, but it's just like, not enough. You know what I mean? This isn't what I want. I want to be seriously big, and it's pretty obvious that nature is never going to make that happen. I'm going to talk to a doctor. I'll tell the others that I'm going to commune with nature so they don't ask what I'm really doing."
The doctor turned out to be a stern-looking man with gray hair and a troubled frown.
"Your penis is 3 inches flaccid and 6 inches erect. That is very normal proportions, and even slightly above average. You should understand that this surgery involves pain and risks. There is no guarantee that you will get the results you are hoping for, so no one should attempt this surgery without serious need, and you do not have serious need."
"You don't understand. I do need this! I've wanted a big penis for as long as I can remember. I've never wanted anything more than I want this. Please, doctor, you've got to help me!"
"Do you understand that if this goes badly wrong, there could be nerve damage? There could even be vascular damage. The worst case outcome is a full amputation of your penis. Are you prepared to accept that risk?"
"I understand. I want to take the risk. I need to."
"Even so, ethics regulations require you to take some time to think about it. We'll schedule the surgery for six months from now, and see if you still want it then."
Beast Boy continued fighting crime with the other Titans while he eagerly waited for his surgery.
One day, the Titans faced a new villain called Apex. He was a very handsome man with flowing blond hair, and he wore a device on his chest that artificially expanded his muscles, giving him super strength that made him a match even for Cyborg and Starfire. He wore a loincloth that flapped around and very poorly concealed a truly enormous penis that hung loose between his massive thighs, easily 14 inches long.
The team was quickly battered and bruised by the battle.
Starfire groaned. Green light flickered in her eyes as her powers failed from being hit so hard by Apex's massive fists. She struggled weakly as Apex ripped off her costume.
Apex slowly grinned as he stared down at Starfire's naked body. He licked his lips.
"Get away from her, you bastard!" Robin snarled as he charged in.
Apex slammed a fist into Robin's chest and pinned the young hero to the ground. Apex grabbed a shard of broken glass with his other hand and stabbed it into Robin's crotch. "Get over yourself, you little idiot."
Robin howled and convulsed in pain.
"No! No... No, my dick! What did you do to me?! My big dick! Please, no!"
Starfire struggled to stand, her eyes growing huge with alarm. "Robin? Robin, are you alright?"
Robin sobbed and rolled around on the floor, seeming to forget about Starfire completely as he clutched the shard of glass in his crotch and tears rolled down his cheeks.
With a furious roar, Beast Boy transformed into a rhino and charged Apex. Beast Boy's horn stabbed into Apex's crotch.
Apex screamed and stumbled backward. He grabbed his crotch with both hands and looked down at himself. "No! This can't happen to me! No, please... Help me!" His face was pale as his huge penis flopped out from under his loincloth and hit the ground with a wet thud, completely severed.
Starfire's eyes blazed green with rage. "You are a bad man, and you do not deserve anyone's help!"
She slammed her fist into the device on his chest, shattering the mechanism into countless pieces, then she hit him again and again. Apex's body shriveled as his muscles faded, and Starfire kept hitting him, her large bare breasts bouncing in her fury.
She then rushed to Robin's side. "Robin! No! What is wrong?! Please speak to me!"
Starfire hugged Robin against her bare breasts and flew him to an emergency room. She watched his sobbing with sad eyes as the doctors worked on him.
Meanwhile, the other Titans took Apex to prison. He was a weak little man with no penis.
Robin's injury had severed his penis. Even after hours of surgery, the doctors were unable to save it.
Robin was crushed. He fell to his knees and stared at his ruined crotch. The other Titans heard Robin sobbing in his bedroom, a display of emotion unlike anything they had ever imagined from him.
Robin's door suddenly opened. Starfire frowned deeply as she stared at Robin curled up on his bed.
"Go away, Starfire."
"Friends do not let friends suffer alone. When you are suffering, I suffer also."
"Please, Starfire, not now."
"Understand that your body has changed, Robin, but it is still beautiful to me. Let me show you."
Starfire dug her fingers into Robin's costume. She easily ripped apart the bulletproof fabric with her Tamaranean strength.
Robin struggled to stop her. He cried out in alarm. "Starfire, wait! Stop!"
She silenced his cries with a heavy kiss, covering his mouth completely. She pinned him to his bed and pressed her large breasts to his chest.
Starfire rubbed her hand up and down his bare belly, warming his skin with fiery green energy. She pressed her palm to the stump of his penis, grinding into his flesh until she felt the stump become hard.
She suddenly pulled back, releasing Robin so she could pull off her own costume. She exposed her large orange breasts and every inch of her orange skin, then stared at Robin with glowing green eyes.
Robin stared at her with his mouth hanging open.
"You see, Robin? You fear that you are broken, but you are not broken."
She straddled his body and pressed her throbbing clit against the stump of his penis. She rocked her hips and ground her flesh against his.
Robin held her breasts with both hands. He groaned hard, writhing between her powerful thighs.
After many minutes, finally Robin's white fluid squirted onto Starfire's slit and the Tamaranean moaned in pleasure.
The next day, Beast Boy cancelled his surgery. Seeing Robin's misery caused Beast Boy's desire for a large penis to fade.
The same day, Raven came to Beast Boy and gave him a sudden hug.
"You've finally made peace with it," she said with an unusual slight tremble of emotion in her gravely voice, "I was afraid you never would, you big idiot."
"You... know about that?"
"I knew a little. Your emotions were screaming at me. I don't know what it was about, but I felt your pain, and now it's gone."
They went into Beast Boy's room and talked quietly.
"You'll think it's stupid if I talk about it."
"It's not stupid, Beast Boy. My powers let me feel what you're feeling, and I understand exactly how important this is to you. I could never laugh at you over something this serious."
"Yeah, but... It's my penis."
Raven's eyes widened, and a blush rose in her pale cheeks. "What about your penis?"
"Like... for as long as I can remember, I've wanted it to be bigger. It's a stupid guy thing, I know. It just seemed like everything would be awesome if it were really huge."
"All this time? But your emotions... they were so intense. I thought it was something more..."
"It was important to me."
"But not now?"
"Yeah. With what happened to Robin and everything, wanting it to be bigger suddenly feels just stupid. Like, it would be nice if it were big, but I really don't think I'm going to worry about it anymore."
"May I see it?"
Beast Boy blushed, his green cheeks turning a darker shade, and then he wordlessly opened the front of his costume to expose his penis.
Raven smirked and tilted her head as she stared at it. "It's not really small at all, is it?"
Beast Boy shook his head and stared at her, at a loss for words.
Raven pulled off her cloak and tossed it away, then she leaned in to press a soft kiss to Beast Boy's lips.
He responded instantly, his hands going to her hips as his penis rose to a rock-hard erection.
She rolled onto her back with Beast Boy between her legs, and she pushed the crotch of her costume to one side as his throbbing green shaft pressed against her slit.
He groaned in excitement as he pushed himself deep into her body. His erection ached from how swollen it was. It was harder than it had ever been. It twitched with every heartbeat. It felt huge as her tight pussy squeezed it.
"It feels pretty big to me," she stammered with a blush in her cheeks.
Her back arched and Beast Boy grabbed her breasts. He massaged her chest through her costume and felt her nipples poking into his palms. He thrust into her faster and faster, carried away with his eagerness.
Raven's eyes turned black as her emotions raced out of control. Her shadow form flooded from her body. It screamed her excitement. It tore the curtains and smashed things around the room. Her shadows grew more and more frantic until she suddenly climaxed and her whole body went stiff. Her shadow faded back into her body as she groaned in pleasure.
He bit his lip and trembled. He squeezed her breasts, kneading his fingers deep into her soft flesh. He resisted as long as he could. Finally his cum squirted out of his young cock and deep into Raven's hot body.
Raven breathed slow, deep breaths. "Would you like to go again?"
Beast Boy and Raven were together all night, and Beast Boy never worried about the size of his penis again.
