The biology building smelled like old textbooks and bleach at night. I liked it that way. Quiet. Predictable. No one asking questions I didn't want to answer. At 20, I had built my entire college life around staying invisible. Straight As, lab reports turned in early, headphones on when I walked across campus. My attraction to men wasn't something I denied anymore in my own head, but I kept it locked behind closed doors. No apps, no bars, no accidental slips. Control was everything.
Then the professor announced semester project partners and called my name with Jake's. Jake Harlan. Twenty one. Water polo captain. Six foot three of lean muscle, golden skin that looked like it absorbed sunlight even in winter, chestnut hair that fell into his eyes when he laughed. He moved like the water still carried him, smooth and powerful. In class he sat two rows ahead, and I had trained myself not to stare at the way his shoulders filled out his hoodie or how his thighs strained the seams of his jeans when he crossed his legs. We had exchanged maybe fifty words total before that day. Mostly about buffer solutions and gel electrophoresis; polite and professional.
Our project was neuromuscular physiology. Voluntary contraction, reflex arcs, the way nerves fire and muscles respond. We needed data we could feel, the professor said. Hands on. Jake texted me that afternoon. Basement lab. 10 pm. Bring coffee.
I arrived early with two black coffees and my laptop. The hallway lights were dimmed to save energy. Jake was already there, sprawled in one of the rolling chairs, legs spread wide, gym bag at his feet. He wore navy compression shorts that left nothing to the imagination and a faded team tank top soaked dark across the chest from whatever practice he'd just finished. Chlorine clung to him, sharp and clean, mixed with the warmer scent of fresh sweat. My stomach tightened the second I saw him.
"Perfect timing," he said, standing up to take one of the coffees. His fingers brushed mine. Deliberate or not, I couldn't tell. "Ready to get dirty?"
I laughed nervously. "It's just data collection."
He raised an eyebrow. "Sure. But data feels better when its real."
We set up on the long steel bench. Diagrams spread out, electrodes and a simple reflex hammer for the patellar test, notebooks open. Jake leaned over my shoulder to point at the quadriceps illustration. His bare arm pressed against mine. Heat poured off him.
"Textbooks suck for this part," he said. "You can't really understand contraction until you feel it. I'll be the subject. You record."
Before I could protest he gripped the hem of his tank and peeled it off. The fabric stuck for a second to his damp skin, then came free. His torso was a map of hard lines. Broad pecs dusted with faint hair, nipples dark and tight from the cool air, abs carved deep enough to catch shadows under the fluorescents. A thin happy trail led down from his navel and vanished into those compression shorts. My mouth went dry.
"Jake..."
He flexed his arms casually, biceps swelling, veins popping along his forearms. "Start here. Feel the biceps brachii. Contracted versus relaxed."
My hand lifted like it had a mind of its own. I pressed my palm to the thick swell of his upper arm. Hot. Solid. When he flexed harder the muscle jumped under my fingers, rock hard. He let out a low breath through his nose.
"Good," he murmured. "Now the pecs."
I slid my hand down. His chest rose and fell faster now. I cupped one pec, thumb grazing the edge of his nipple. It pebbled instantly. He hissed softly.
"You feel that response?" he asked, voice rougher. "Thats voluntary control. Now do the other one."
I mirrored the touch. His skin was fever hot. My cock was already straining against my jeans, thick and aching. I tried to focus on breathing.
Jakes eyes darkened as he watched me. "Youve been looking at me for weeks, Ethan. Dont think I havent noticed. The way your gaze lingers when I stretch after class. When I pull my hoodie off in the lecture hall. You want to know what it feels like, don't you?"
My face burned. "I didn't mean..."
"Shh." He caught my wrist and guided my hand lower, over the ridges of his abs, stopping just above the waistband. "No lying. Not here. Not tonight."
He hooked his thumbs into the shorts and shoved them down in one motion. They puddled at his ankles. His cock swung free, thick and heavy, already thickening. Uncut, the foreskin partially retracted to reveal a flushed head already shiny with a bead of pre-cum. Veins traced the shaft like rivers on a map. His balls hung low, full and smooth. The scent hit me hard, musk and clean sweat and something darker, primal.
"Touch it," he said quietly. "Get your data."
My fingers closed around the base. He was scorching, velvet over iron. As I stroked upward the foreskin slid back fully, exposing the swollen head. More precum welled and coated my palm. Jake groaned, hips rocking forward into my grip.
"Slow," he instructed. "Feel every inch. Watch how it responds."
I obeyed, sliding my fist up and down, twisting lightly at the crown. His cock lengthened to nine solid inches, girth stretching my fingers apart. The head glistened, angry red and dripping. His abs clenched with each stroke, a thin sheen of sweat breaking across his chest again.
"Fuck, your hand feels good," he breathed. "But I want more. Get on your knees."
I dropped without thinking. The tile was cold against my shins. His cock bobbed inches from my face, heavy and leaking. I leaned in and licked the slit, tasting salt and heat. Jake shuddered.
"Open your mouth, boy."
I parted my lips. He fed the head past them, stretching my mouth wide. The taste exploded on my tongue, musky and addictive. I sucked harder, swirling around the ridge. He threaded his fingers through my hair and pushed deeper.
"Deeper, Ethan. Relax your throat. Take it all."
I gagged once, eyes watering, but he held me steady. "Breathe. Through your nose. Good boy. Just like that."
He started thrusting, slow and deep, fucking my mouth with measured strokes. Drool ran down my chin, mixing with his steady leak of precum. My own cock throbbed painfully, untouched, soaking through my boxers. Every time he bottomed out his balls tapped my chin, heavy and warm.
Minutes blurred. My jaw ached in the best way. Jake pulled out suddenly, cock slick and shining, strings of saliva connecting us. "Strip. I want to see your body too."
I stood on shaky legs and yanked off my hoodie, t shirt, jeans. When my briefs came down my erection sprang free, six and a half inches, painfully hard, the tip shiny with precum. Jake looked me over like I was something he had been waiting to unwrap.
"Beautiful," he growled. He stepped behind me, chest to my back, cock sliding hot and wet between my cheeks. "Hands on the bench."
I braced myself. He spit into his palm, coated his cock, then pressed two thick fingers against my hole. I gasped as the first one breached me, burning stretch that melted into pleasure when he crooked it against my prostate. A second finger joined, scissoring, opening me up. I pushed back, desperate.
"So tight," he muttered. "Gonna feel fucking incredible."
He pulled his fingers free and lined up. The fat head nudged my entrance. "Breathe."
He pushed in slow. The stretch was intense, almost too much, then the head popped past the ring and he sank deeper, inch by burning inch. When his hips met my ass I moaned loud enough to echo off the walls. Full. Stretched. Owned.
Jake stayed still for a moment, letting me adjust, then started moving. Long, deep rolls at first, dragging his cock over every sensitive spot inside me. Then harder. Faster. Each thrust punched the breath from my lungs. The bench rattled. Skin slapped skin. His balls smacked my ass with every drive.
"You take it so well," he panted. "Look at you, opening up for me. Made for this cock."
His hand wrapped around my dripping length, stroking in perfect time with his brutal rhythm. I was leaking steadily, precum stringing from the tip to the floor. My balls drew up tight.
"Jake... Im close..."
"Come for me," he ordered. "Let me feel you squeeze."
The command shattered me. My orgasm ripped through, cock pulsing hard in his fist, thick ropes shooting across the steel bench and dripping to the tile. My hole clenched rhythmically around him.
"Fuck yes," he groaned. "Milk me."
He slammed in one final time, burying himself to the hilt. His cock swelled, throbbed, then erupted. Hot spurts flooded me, pulse after pulse, filling me until I felt it leaking out around his shaft, running down my thighs in warm rivulets.
We stayed locked together while our breathing slowed. He softened inside me, still twitching. When he pulled out a thick stream of cum followed, sliding down my leg. He turned me around, cupped my face, and kissed me slow and filthy, tongue claiming every corner of my mouth.
"Best data I've ever collected," he murmured against my lips, smirking. "And we've got the whole semester to replicate the results."
I laughed, boneless and buzzing, already craving the next session.
From now on, every lab session was going to end exactly like this.
