We'd always been close, but that summer after college everything changed in ways I never expected. I was twenty-two, home for good, and my older brother Mark had just turned twenty-four and landed his first real job. The house was empty most days with our parents working long hours, so it was just the two of us rattling around in the old place.
It started with stupid shit. Late-night movies on the couch, beers we weren't supposed to have, the kind of roughhousing that turned into longer holds. One night we were wrestling over the remote and I ended up pinned under him, both of us breathing hard. His body was heavier than I remembered, solid from the gym, and when he shifted I felt him hard against my thigh. Neither of us moved for a second too long. Then he rolled off, laughing it off like it was nothing.
The next night it happened again, only this time there was no remote excuse. We were in his room, supposed to be watching some dumb action flick on his laptop. The room was dark except for the screen glow. Mark sat on the edge of the bed and I was on the floor between his legs, leaning back against the mattress. His hand dropped to my shoulder, casual at first, then his fingers started rubbing slow circles. I didn't stop him. My heart was hammering so loud I was sure he could hear it.
"You ever think about this?" he asked, voice low. His thumb brushed the side of my neck.
I swallowed. "About what?"
Instead of answering he leaned down and kissed the top of my head, then my temple. When I turned my face up he met me halfway. The kiss was rough and unsure at first, teeth clicking, but then his tongue pushed in and I opened for him like I'd been waiting years. My cock was already straining against my jeans.
Mark pulled back just enough to yank his shirt off. "Get up here," he said, and I climbed onto the bed. We stripped fast after that, clothes hitting the floor in a messy pile. His body was all hard lines and dark hair trailing down his stomach. Mine was leaner, smoother. He looked me over once, then shoved me onto my back and climbed on top.
His mouth went straight to my neck, biting and sucking while his hand wrapped around both our cocks. The first slide of skin on skin made me groan loud enough that he slapped a hand over my mouth. "Quiet," he warned, but he was grinning. He stroked us together, slow and tight, precum mixing and making everything slick. I thrust up into his fist, chasing the feeling.
When he let go I almost complained, but then he moved lower. His tongue dragged down my chest, over my nipples, then lower still. He hesitated for half a second before taking me into his mouth. The heat of it was shocking.
He sucked awkwardly at first, learning the shape of me, but the sight of my brother's lips stretched around my cock was enough to push me close to the edge fast. I warned him with a tap on his shoulder and he pulled off, crawling back up to kiss me again so I could taste myself on his tongue.
"Your turn," I managed, and he flipped onto his back without argument. I went down on him slower, savoring every inch. He was thicker than me, veins standing out, and the way he cursed under his breath when I took him deep made me feel powerful. I worked him with my mouth and hand until his hips started bucking. He pulled me off before he came.
"Not yet," he said, voice wrecked. "I want to fuck you."
We both knew what that meant. I'd never done it before, but neither had he. He grabbed lube from his nightstand drawer like he'd been planning this. I got on my hands and knees, heart pounding. The first press of his finger was strange, then two, scissoring me open while he murmured filthy encouragement against my spine. When he finally lined up and pushed in it burned, but he went slow, one hand stroking my back, the other reaching under to jerk me in time with his thrusts.
Once he was all the way inside we stayed still, breathing together. Then he started moving. Each thrust went deeper, hitting something that made my vision blur. I pushed back to meet him, skin slapping, sweat dripping. Mark leaned over me, chest to my back, biting my shoulder as he fucked harder. The angle changed and I came without touching myself, spilling across the sheets while I clenched around him. He followed seconds later, groaning my name as he filled me.
We collapsed in a sweaty heap. After a minute he pulled out carefully and rolled me to face him. We kissed again, slower this time, almost sweet. No one said anything about stopping or regretting it. Instead he reached down and started stroking me again, already getting hard once more himself.
"Round two," he whispered against my mouth. "This time I want you on top."
We didn't leave the room for hours. By morning we both knew it wasn't a one-time thing. The first time had just opened the door.
