I walked in on my little brother wearing my ex's panties again. He was eighteen, just like me, but he looked softer, smaller, with that smooth shaved body and the way his dick strained against the pink lace. "Fuck, Jake," I said, shutting the door behind me. "You stealing my shit now?"
He turned around, face red but eyes daring me. "They feel good on my ass. You want them back or you gonna do something about it?"
I didn't answer with words. I grabbed him by the hips, spun him to face the mirror, and yanked those panties down just enough to expose his tight hole. "You been practicing with that dildo I found in your drawer?" I spit on my fingers and shoved two straight in. He moaned like a slut, pushing back.
"Yeah, big brother. Every night thinking about your cock."
I worked him open rough and fast, no lube except spit and his own pre-cum. When he was dripping and begging, I pulled my dick out and slammed in balls deep. His femboy ass took it like it was made for incest. "Fuck, you're tighter than any girl," I growled, pounding him against the dresser. The panties were still around his thighs, stretched and soaked. Every thrust made his cheeks jiggle and his voice crack.
He came first, shooting all over the mirror without touching his dick. That squeezed my cock so hard I filled him up, pumping thick loads into his guts. We didn't stop there. I flipped him onto the bed, ripped the panties off completely, and made him suck me clean while I fingered the cum back into his hole.
"Swallow it all, you dirty little brother slut." He did, eyes watering, throat working. Then I bent him over again for round two, this time slower but deeper, making him feel every inch. "Tell me how much you love your brother's dick in your femboy ass."
"Love it," he gasped. "Fuck me harder. Breed me again."
We spent the whole afternoon like that, switching positions, using his mouth, his ass, even jerking off onto his face while he wore nothing but thigh-high socks. By the time we were done, he was leaking cum from both ends and smiling like he'd won the lottery.
Next morning he came into my room wearing nothing but those same ruined panties. "Round three?" he asked, crawling onto the bed and spreading his legs.
I didn't need asking twice. I buried my face between his cheeks first, tongue-fucking his used hole until he was shaking. Then I flipped him and fucked him missionary so I could watch his pretty face while I wrecked him. "You're mine now," I told him, choking him light while I pounded. "No more hiding. We do this every day."
He came again, untouched, clenching around me. I pulled out and painted his flat chest and stomach, rubbing it in like lotion. "Lick it off my fingers," I ordered. He sucked them clean, moaning.
From then on it was constant. Shower sex where I'd pin him to the wall and rail his ass until hot water ran cold. Late-night visits where he'd sneak in wearing lingerie and ride me reverse cowgirl, that smooth femboy body bouncing on my cock while he whispered filthy shit about how wrong it was and how good it felt.
One night I had him on all fours in the living room, pounding him while our parents were asleep upstairs. "Quiet," I hissed, covering his mouth. "Or they'll hear their sons fucking." He bit my hand and came anyway, ass milking me dry.
We got bolder after that. Car sex on the way to the store, quickies in the laundry room with him bent over the washer. Always raw, always deep, always with him in some piece of feminine shit that made his ass look even better. He started buying his own panties, thongs, even a little skirt he wore just for me so I could flip it up and fuck him without taking it off.
The best was when he let me film it once. "For us," he said.
Watching the video later, seeing my dick disappear into his stretched hole while he begged for more, got us both hard again instantly. We watched it together and fucked to the sound of our own moans.
It never got old. Every time he walked past me in those tiny shorts or bent over on purpose, I knew exactly what he wanted. And I gave it to him hard, dirty, and often. My femboy brother was the best fuck I'd ever had, and the fact it was forbidden only made it hotter. We kept it going for months, sneaking, planning, and ruining every pair of panties he owned with cum and spit and sweat.
Eventually we stopped pretending it was just sex. It was ours. Raw, constant, and exactly what we both needed.
