I had been sneaking into my brother's room every night for weeks. At twenty-one, I knew exactly what I wanted, and it was his thick cock buried deep inside me. That night I crept in wearing nothing but a tiny tank top, my pussy already dripping down my thighs. He was asleep on his back, the sheet tented over his hard-on. I didn't waste time. I climbed on, grabbed his shaft, and sank down onto it in one smooth motion.
"Fuck, sis," he groaned, waking up with his hands on my hips. "Ride that cock like you own it."
I did. I bounced hard, my ass slapping against his balls, my tits jiggling under the thin fabric. "Your cock feels so fucking good," I hissed, grinding my clit against him on every downstroke. "Deeper, give it to me deeper."
He thrust up to meet me, stretching my tight cunt wide. The wet sounds filled the room—schlick, schlick, schlick—as my juices coated his shaft and ran down to his balls. I leaned forward, hands on his chest, and rode him faster, slamming myself down until the head of his cock punched against my cervix.
"Harder, you little slut," he growled, slapping my ass. "Fuck your brother's cock."
I moaned loud, not caring who heard. My pussy clenched around him, milking every inch. I was close, so close, when the door creaked open.
Our mother stood there in her robe, eyes wide. For a second nobody moved.
My brother's cock was still buried to the hilt in my cunt, my juices glistening on the base.
"Caught you," she said, voice low and rough. But she didn't leave. She stepped inside and shut the door. "Keep going."
I froze, but my brother grabbed my hips and started fucking up into me again. "She wants to watch, sis. Ride it."
Heat flooded me. I started moving again, slower at first, then faster, putting on a show. Mom dropped her robe. Underneath she was naked, nipples hard, one hand already between her legs. "That's it," she whispered. "Fuck your brother. Let me see that pussy stretch."
I rode him harder, dirty words spilling out. "Watch me take his cock, Mom. Watch me come on my brother's dick." My orgasm hit fast and brutal. I shook and clenched, flooding him with fresh wetness while he kept pounding.
Mom moved closer, fingers working her own clit. "Fill her up," she ordered. "Come inside your sister."
He did, groaning as his hot load pumped deep into my cunt. I kept riding through it, squeezing every drop out, until his cock softened and our mixed cum leaked out around his shaft.
Mom climbed onto the bed behind me, her hands on my ass. "My turn to taste," she said, and leaned in to lick the mess from where we were still joined. I moaned again, already wanting more.
We didn't stop until morning.
