I never planned on becoming my brother's sissy whore, but the moment he caught me in Mom's old lingerie, everything changed. It was late, the house quiet, and I stood in front of the mirror wearing a lacy black bra, matching panties, and stockings that hugged my shaved legs. My cock was already hard and leaking, tucked awkwardly to the side. Then the door opened and there he was, Jake, six years older, built like a linebacker, staring at me with a smirk that turned my stomach and made my dick twitch harder.
"Look at you, little brother," he said, voice low and rough. "Dressed up like a cheap slut. You want cock that bad?"
I froze, face burning, but I didn't move to cover up. Jake stepped inside and locked the door. He grabbed my chin, forced me to meet his eyes. "Answer me. You want to be a sissy for real?"
"Yes," I whispered. The word slipped out before I could stop it.
He laughed, a dirty sound, and shoved me onto the bed. His hands were big and rough as he yanked the panties down just enough to free my cock. It sprang up, small and desperate next to his. He didn't even undress at first, just pulled his thick dick out of his jeans and slapped it against my face.
"Suck it, sissy. Show me how much you need your brother's cock."
I opened my mouth and he pushed in deep, no warning, choking me on the first thrust.
Saliva spilled down my chin while he fucked my throat, calling me names the whole time. "That's it, take it like the incest-loving faggot you are. Bet you've dreamed about this, huh? Your big brother turning you into his personal cumdump."
He pulled out long enough to strip me the rest of the way, leaving the bra and stockings on. Then he flipped me onto my stomach, spread my cheeks, and spat on my hole. One thick finger pushed inside, then two, stretching me while he told me exactly what he was going to do.
"Gonna fuck this sissy pussy raw. Gonna breed my own brother until you're leaking my load all night."
When he finally shoved his cock in, it hurt and felt perfect at the same time. He didn't go slow. He pounded me hard, hips slapping my ass, one hand fisting my hair so I had to look back at him. "Tell me whose slut you are."
"Yours," I gasped. "I'm your sissy incest slut, Jake."
He fucked me through two orgasms, making me come untouched on the sheets while he kept railing my hole. The second time he came, he stayed buried deep, grinding in circles so every drop stayed inside. When he finally pulled out, he made me lick him clean, then pushed two fingers back into my messy hole and fed me the cum that leaked out.
"Keep those panties on," he ordered afterward. "Tomorrow night you're wearing a dress. And you're calling me Daddy while I fuck you again."
I nodded, already hard again, knowing this was only the beginning. Every night after that, Jake used me however he wanted. Sometimes he made me wear full makeup and heels while he fucked my throat. Other times he bent me over the kitchen table the second our parents left, pounding my sissy hole until I was sobbing his name. He loved making me beg for it, loved hearing me say filthy things like "Please breed your little brother's pussy" and "I want to be your incest sissy forever."
Weeks later he bought me a chastity cage and a bigger plug. "You're not coming unless I say so," he told me, locking my cock away. "From now on this sissy clit only gets attention when I'm balls-deep in you."
The first time he fucked me while I was caged, the pressure was insane. I came dry, shaking and whimpering, hole clenching around his cock. Jake just laughed and kept going, filling me up again and again until my legs gave out.
By the end of the summer I was his completely. Shaved smooth, always in panties under my clothes, ready whenever he snapped his fingers. He even started inviting a couple of his friends over on weekends, making me serve them on my knees while he watched and stroked himself. "That's my good sissy incest whore," he'd say, voice full of pride and lust. "Taking every cock I give you."
And every time he said it, I got harder in my cage, desperate for the moment he'd finally unlock me and fuck me senseless again. I stopped pretending I wanted anything else. I was Jake's sissy, his secret, his filthy little brother who lived for his cum. And I never wanted it to end.
