I keep thinking about being kept full and pregnant, belly growing while my body is used over and over, never given a real break. The idea of belonging to someone who wants to breed me until I’m leaking and marked as theirs won’t leave my head. I don’t just want the sex I want the purpose of it, the constant reminder that I’m there to be filled and claimed.

I imagine coming home already soft and swollen, knowing another load is waiting for me the second I walk through the door. No birth control, no pulling out, just being taken whenever they want and left dripping. The thought of building a whole messy, overfilled little family like that makes me so wet it’s almost embarrassing. I need it more than I should.

I finally let my younger brother fuck me.
He’d been begging for months jerking off to me, “accidentally” walking in while I was changing, leaving his door open so I could see that fat cock of his. Tonight I cracked. We were alone in the house. I walked into his room in just a tank top and a black thong, locked the door behind me, and said, “Fine. One time. Get it out of your system.”
He didn’t waste a second. He yanked the thin thong aside, spun me around, and bent me over his bed. I felt the head of that huge dick press against my pussy thick, heavy, already leaking. He pushed in and my mouth fell open. Jesus Christ, he was big. Bigger than anyone I’d ever taken. The stretch burned in the best way as he forced every inch inside me until his balls were pressed against my clit, the thong still stretched around one thigh.
“Fuck, sis… you’re so tight,” he groaned, gripping my hips hard enough to bruise. He started pounding me, long deep strokes that made the bed slam against the wall. My tits bounced under the tank top with every thrust. I was already dripping down my thighs, moaning into the mattress like a slut.
He was balls-deep, fucking me hard and fast, when the door opened.
Our mom stood there.
She froze. Eyes wide. Staring right at the spot where my brother’s massive cock was buried in me, the black thong still hooked around my thigh. He didn’t even try to hide it. He pulled all the way out slowly, that long, glistening shaft sliding free, and held it in his fist so she could see every thick inch of it. It was still hard, twitching, shiny with my juices, hanging heavy and huge.
Mom’s eyes locked on it. Her mouth parted. She just stared wide eyed, shocked, clearly measuring how long and thick her son’s dick was. For a second nobody moved. Then she turned around without a word and walked out, quietly closing the door behind her.
My brother didn’t hesitate. He slammed that huge cock straight back into me in one hard thrust, burying it to the hilt. I cried out as he started railing me even harder, like the interruption never happened. The wet slap of his hips against my ass filled the room, the thong still half-on and soaked. He fucked me deep and rough, that fat dick stretching me open over and over while I clenched around him and came hard, soaking his balls.
He kept going, pounding me through it, muttering, “She saw how big I am… she fucking saw,” while he used my pussy like it belonged to him.
