We were both home for the weekend, me and my older brother Jake, crammed back into the old house like nothing had changed. At 25 and 28, we still acted like horny teenagers when no one else was around. The shower was the only place with real privacy, and that Saturday night after the gym, we both needed it bad.
Jake went in first, but the water was running too long. I banged on the door. "Hurry the fuck up, man. I'm covered in sweat."
"Door's unlocked," he called back, voice echoing off the tiles. "Get in if you're that desperate."
I didn't think twice. We had shared showers before as kids, but this was different now. I stripped down and stepped in. The stall was tight, steam thick, and Jake's naked body was right there, water cascading over his broad shoulders and down his thick chest. His cock hung heavy, half-hard already from the heat.
"Fuck, it's small in here," I muttered, trying not to stare.
Jake grinned, that cocky older-brother smirk. "Then get closer. Soap my back while you're at it."
I grabbed the bar and started rubbing it over his shoulders, down his spine. My hands slipped lower, and I felt his ass flex under my palms. He pushed back a little. "Lower. Yeah, like that."
My own dick was starting to twitch, brushing against his thigh. Jake turned around, water hitting both of us now. "You hard already, little brother? Damn, look at that cock."
He reached down and wrapped his fingers around me, stroking slow and firm. "Been wanting to do this for years. You too, right? Don't lie."
"Yeah," I admitted, voice rough. "Fuck, Jake, your hand feels good."
He dropped to his knees right there in the spray, water pounding on his head as he took my cock into his mouth. Hot, wet suction, tongue swirling around the head, then swallowing deeper. I grabbed his hair, thrusting shallow at first. "Suck it, bro. Take that dick."
Jake moaned around me, one hand stroking his own thick shaft. He pulled off with a pop, spit and water dripping from his lips. "Turn around. Let me eat that ass."
I braced against the wall. His tongue hit my hole, licking and pushing in, getting me sloppy wet while his fingers teased my balls. The water made everything slicker, dirtier. I reached back and spread myself for him. "Deeper, Jake. Fuck, that feels nasty."
He stood up, pressing his cock between my cheeks, sliding it along my crack without entering yet. "You want your brother's dick in you? Say it."
"Give it to me," I growled. "Fuck your little brother in the shower."
Jake lined up and pushed in slow, inch by inch, stretching me open. The burn mixed with the hot water, turning into pure heat. He bottomed out and started pounding, hips slapping against my ass, water splashing everywhere. "Tight fucking hole. Been saving this for me?"
I pushed back to meet every thrust. "Harder. Pound me, Jake."
He reached around and jerked my cock in time with his strokes, grunting filthy encouragement in my ear. "Gonna fill you up. Shoot my load deep in your ass, bro."
We switched positions after a while. I dropped and sucked him clean, tasting the mix of soap and precum, then he bent me over again for round two. This time he fingered me open while stroking himself, adding more lube from the body wash. "Look at you, leaking for it."
When he slid back in, it was even deeper. We fucked standing, then with me on the shower bench, legs spread wide. Jake's balls slapped against me, his cock hitting that spot over and over until I was moaning loud enough to echo. "I'm close, fuck, don't stop."
He jerked me faster. "Come on my dick. Do it."
I shot hard, ropes hitting the wall and mixing with the water. Jake followed seconds later, burying himself and pumping me full, groaning my name like a curse. "Take it all, little brother. Fuck yeah."
We stayed locked together under the spray until the water started to cool.

Jake pulled out slow, cum leaking down my thigh. He kissed the back of my neck, rough and brotherly at the same time. "Shower's ours now. Every weekend."
I turned and kissed him on the mouth, tongues sliding, both of us still half-hard. "Next time I'm fucking you."
We rinsed off, bodies pressed close, hands roaming again. The steam kept rising, and neither of us was in any hurry to leave.
