The Key that Fits

**This story won't be for everyone; it has themes that might be described as unusual. Small penis humiliation, cuckolding, cheating, voyeurism, and this story has some non-consensual elements and bullying. No part of this is to be taken seriously; it's meant to be fun and a creative writing exercise for myself. You can find more of my stories on Literotica under Runtz3 and Runtz4**

The past four years at university were finally coming to an end, and Laura couldn’t wait for it to be over. She and Henry had been together for sixteen months now, but between her loud roommate Janet and Henry’s loud-mouthed teammate Steve, peace had been in short supply.

Laura wasn’t looking for a boyfriend when she started her first year. Head down in her books, full-ride scholarship to protect, and far too aware of the way her 5'4" body turned heads. Voluptuous 34DD breasts, thick thighs that filled out every pair of jeans, long dark wavy hair, and soft brown eyes — even in modest clothes, she drew stares.

Henry had been different from day one. In first-year world geography, he simply sat beside her, funny and sweet, never leering. They kept ending up in the same classes, sharing notes, studying late. By the end of their third year, Laura was the one who worked up the courage.

“Henry?” she asked, heart fluttering. “Would… would you like to go someplace with me? Like Friday night?”

He smiled, running fingers through his thick brown hair. At 5'7", he was only a little taller than her, lean from years of soccer. “Wait… like a date?”

“Yeah… is that okay?” She smiled, her hand trembling just a bit as she brushed her hair over her ear. 

Since that time, they've been together. They shared so many interests, and they also shared one social detail... they were both virgins. Something they determined to remedy over summer break. Their first time was a bit clumsy, if not highly enthusiastic. It was fully planned and discussed ahead of time. She had gone on birth control years ago to help regulate her cycle, but insisted he wear a condom just to be safe.

That summer, they planned it carefully in her dorm while Janet was away. Candles, soft music, birth control already sorted. Henry was nervous, gentle, and patient, even though he clearly wanted to rip her top off and grope her huge tits. 

When she finally pulled his shorts down, his smooth, hairless groin and modest cock looked perfectly fine to her inexperienced eyes. Soft it was barely more than a plump little head resting on his balls, like a shy pale grape. Hard it reached a neat four inches.

It was nothing like she heard from other girls; it was pleasant and easy. He never hurt her, not once. As he pushed deep inside her, bottoming out, she laughed a little to herself. That was no big deal at all.
And in just a few short strokes, he was tensing, and then shuddered as he came inside her.

Her eyes widened as he quickly slid out, planting his face between her legs and licking her to her first orgasm ever. She had heard that most girls don't enjoy their first time, and she felt blessed to have a great memory. That night, they used 5 more condoms; his recovery time was nothing. She never came from his penis, but he took care of her each and every time with his mouth.

It was sweet. It was theirs.

Then Janet started dating Steve.

Janet was 5'8" of pale, freckled chaos with wild red curly hair and a tight 32B body that lived in tiny tops, and Lauara was convinced she had never even owned a bra. A free-spirited nympho who made everything sexual. Steve — 6'3", blond scruffy face, blue eyes, model looks, and a permanent rich-boy smirk — played striker on the same soccer team as Henry. He had a thick Cockney edge to his voice that got rougher when he was taking the piss out of people.

From the first locker-room sighting, the nickname stuck.

“Oi, Little Hank!” Steve would shout every time he saw him.

Laura thought it was about height. Until the night Steve and Janet were making out heavily on one bed while she and Henry tried to watch a film on the other.

“Steve, noooo!” Janet laughed, pushing him back. Her perky tits strained against her thin t-shirt.

“Come on, babe,” Steve grinned, his feet hanging off the end of the bed. “I ain’t shy, no need, got nothin’ to be embarrassed ‘bout. Not like Little Hank over there, yeah.”

“Stop calling him that!” Laura snapped. “He’s not even that short.”

Steve barked a laugh. “Short? Nah, love, it’s ‘cause of his tiny button dick!”

“Steve, please…” Henry muttered.

Laura jumped in to defend him. “He’s only small when he’s soft. When he’s hard, it sticks out a little past my fist.” She held up her small hand to show them.

Janet and Steve lost it, howling with laughter.

“You should see it soft!” Steve crowed, talking to Janet. “Like a little pale grape sittin’ a top of his hairless balls, innit? Smallest on the whole fuckin’ team.”

He stood up, yanked his shorts down, and gripped his heavy cock. Laura’s eyes went wide. Even completely soft, it was thick and long — easily six inches of meaty man flesh swinging in his big hand. He spun it around like a helicopter.

“I ain’t even ‘ard yet, me thick bird!” he laughed. “When you’re ready for a real man, thick bird, just say the word. Fuck them enormous top bollocks proper, I will.”

That was the first time Laura saw Steve’s cock. It wasn’t the last. He was never shy about “accidentally” exposing himself.

She’d come back to the dorm early from the library and opened the door without knocking. Janet was on all fours on her bed, face buried in a pillow, moaning like a whore. Steve was behind her, gripping her hips and slamming into her with long, brutal strokes. His thick cock looked obscene — easily twice as thick as Henry’s and much longer, veins bulging, shiny with Janet’s cream.

Laura had frozen in the doorway. For several long seconds, her eyes locked onto that massive, pistoning shaft stretching her roommate’s pussy wide open. The wet, filthy schlick-schlick-schlick sound filled the room. Steve had glanced over, caught her staring, and just smirked as he kept fucking Janet even harder.

She’d backed out and closed the door, heart hammering… but the image had burned itself into her brain.

Then there was the afternoon in the dorm when she walked in and Steve was sitting on the edge of Janet’s bed in a pair of loose basketball shorts, legs spread. His heavy cock had slipped out the wide leg hole, hanging thick and soft against his thigh — at least six inches of meat even completely limp. He didn’t bother covering it. He just looked up at her with that cocky grin.

“Alright, thick bird?”

Laura had muttered something and looked away, but her eyes kept flicking back to it. She hated how heavy and full it looked. How different it was from Henry’s tiny little nub.

The worst — or best — was the night she was already in bed, lights off, trying to sleep. Janet and Steve thought she was out cold. She heard the familiar wet sucking sounds and couldn’t help herself. She cracked one eye open just enough to see.

Janet was on her knees between Steve’s legs, greedily sucking his huge cock. Even in the dim light from the streetlamp outside, Laura could see everything — Janet’s lips stretched obscenely wide around the thick shaft, saliva dripping down onto his heavy balls as she bobbed and gagged. Steve’s hand was in her red hair, guiding her deeper.

“That's it, love… choke on that fat dick,” he groaned in his dirty accent.

Laura’s hand had slid into her panties almost on its own. She found her clit soaked and swollen. She rubbed herself in slow, guilty circles while she watched her roommate worship that massive cock. When Steve finally growled and started pumping cum down Janet’s throat, Laura came too — a quiet, shaking orgasm that left her biting her lip so hard she nearly drew blood.

She came again later that week, replaying the image of Steve with Henry’s tongue buried deep inside her.

She told herself it was just curiosity. Nothing more.

But deep down, she knew she was lying.

Janet only poured fuel on the fire, casually complaining how sore she was after Steve fucked her senseless, how many times she came on his big dick, and how teasing her about how Henry’s fully hard penis was still smaller than Steve’s soft cock.

So when Janet begged them to come on this holiday — “Steve’s dad has a little place on the islands, it’s our last proper break before graduation, you deserve it” — Laura had reluctantly said yes. It was a chance for her and Henry to have a special time together. And, one last trip before graduation.
