I never planned for it to happen that way. I was twenty-two, fresh out of college, and spending a long weekend at my uncles mountain cabin with a group of friends. The place had a big wooden deck overlooking the pines, and right in the center sat this huge jacuzzi that bubbled like it was alive. Most nights we all piled in after dinner, beers in hand, laughing and splashing. But one evening everyone else crashed early, and it was just me and Derek left.
Derek was older, maybe twenty-eight, with broad shoulders and a quiet way of looking at you that made my stomach flip. Wed known each other through mutual friends for a couple years, but never alone like this. The night air was cool, steam rising thick from the water. I stripped down to my swim trunks and slid in first. Derek followed, settling across from me, the jets churning between us.
We talked for a while about nothing, the usual stuff. Then the conversation drifted. He asked if Id ever been with a guy. I laughed it off at first, but the words came out honest before I could stop them. No. Never. Thought about it though. My face burned, but the dark and the bubbles hid it.
Derek didnt laugh. He just watched me, eyes steady. What have you thought about? His voice was low, almost casual, but there was heat under it.
I swallowed. Kissing. Touching. Maybe more. The confession hung there between us. My cock was already thickening against the fabric of my trunks, the warm water doing nothing to calm it.
He moved closer, slow enough that I could have backed away. I didnt. His hand found my knee under the water, thumb stroking lightly. You want to try? he asked.
I nodded. That was all it took. He leaned in and kissed me, mouth firm and tasting faintly of beer. My first real kiss with a man. It felt electric, different from anything with girls. His tongue slid against mine and I groaned into it, hands coming up to grip his shoulders. We kissed harder, water sloshing around us. His palm slid up my thigh and closed over my cock through my trunks. I jerked at the touch, hips pushing forward on instinct.
Fuck, I breathed when he pulled back. That feels good.
Derek smiled, small and knowing.

He tugged my trunks down and off, tossing them onto the deck. My cock sprang free, hard and flushed. He wrapped his fingers around it and stroked once, slow and firm. I had to bite my lip to keep from moaning too loud. The jets kept pulsing against my back and ass, adding to the sensation.
He guided my hand to his own trunks. I pushed them down, feeling the thick length of him for the first time. He was bigger than me, hot even in the warm water. We stroked each other for a while, kissing between breaths, learning the rhythm. My nerves were still there but melting fast under the pleasure.
Derek shifted, pulling me onto his lap so I straddled him. Our cocks rubbed together under the water. He reached between us, fingers slick with the water and pre-cum, and traced down behind my balls to my hole. The touch made me tense, then relax as he rubbed slow circles.
Tell me if you want to stop, he said against my ear.
Dont stop, I answered. My voice sounded rough.
He worked one finger inside me, gentle at first, letting the jacuzzi jets help ease the way. The stretch burned a little, but it quickly turned into something hotter, deeper. I rocked on his finger, getting used to the feeling. He added a second, scissoring carefully, stretching me open while his other hand kept stroking my cock. I was panting, forehead against his shoulder.
When he thought I was ready, he lifted me a little and lined himself up. The head of his cock pressed against my hole, thicker than his fingers. Breathe, he murmured. I did, and he pushed in.
It hurt at first, a sharp stretch that made me gasp. He stopped, holding still, letting me adjust. The water helped, the heat and bubbles relaxing my muscles. Inch by inch he sank deeper until he was fully inside me. I felt impossibly full, stretched around him in a way that sent sparks up my spine.
God, youre tight, he groaned. His hands gripped my hips.
I started moving, small rocks at first, then longer slides. The pain faded into a heavy, rolling pleasure. Every time he bottomed out it hit something inside me that made my cock twitch and leak. The jacuzzi jets kept swirling around us, adding constant vibration against my skin. Derek thrust up to meet me, steady and deep. Water splashed over the edge of the tub.
We found a rhythm. I rode him, hands braced on his chest, while he reached between us to jerk my cock in time with his thrusts. The combination was overwhelming. My first time being fucked, and it was happening in this steaming, bubbling water under the stars. Every sensation felt amplified.
Dereks breathing grew ragged. He thrust harder, water churning white around us. You feel so fucking good, he said, voice strained. I could only moan in answer, chasing the building pressure in my gut.
I came first, sudden and hard. My cock pulsed in his fist, shooting thick ropes that the water quickly washed away. My hole clenched around him and that pushed Derek over too. He buried himself deep and came with a low growl, heat flooding inside me.
We stayed like that for a minute, breathing hard, his arms around me. Eventually he eased out, gentle as he could. We floated side by side in the jacuzzi afterward, the water still bubbling around us. My body felt loose and sore in the best way.
Derek looked at me, a small smile on his face. You okay?
I nodded, grinning despite myself. Yeah. More than okay.
We stayed in the water a while longer, talking softly, touching now and then. When we finally climbed out, the cool night air hit our skin, but the heat from what wed done stayed with me. It was the start of something I hadnt expected, but I already knew I wanted more.
