I never planned on fucking my sister. But when you're both adults sharing a cramped apartment after our parents' divorce, things get messy fast. I was twenty-eight, she was twenty-four, and we had always been close. Too close. One humid summer night, after too many drinks, the truth came out.
We sat on the couch in tank tops and shorts, legs touching. "I've always wondered what your pussy tastes like," she blurted, her voice low and direct. My heart slammed. Instead of pulling away, I spread my legs and pulled my shorts aside. "Find out then, sis."
She dropped to her knees right there. Her tongue hit my clit without hesitation, licking hard and sloppy like she'd been starving for it. I grabbed her hair and ground my cunt against her face. "That's it, eat your sister's wet pussy," I growled. She moaned into me, fingers sliding inside, pumping fast. I came hard, soaking her chin, but we weren't done.
I yanked her up, stripped her, and bent her over the arm of the couch. Her ass was perfect, round and firm. I spread her cheeks and buried my tongue in her asshole first, then dragged it down to her dripping slit. She tasted sweet and forbidden. "Fuck me with your fingers," she begged. I shoved three in deep, curling them against her G-spot while my thumb worked her clit. She screamed my name as she squirted all over the cushions.
We moved to the bedroom. I strapped on the harness we bought as a joke months ago and fucked her from behind like an animal. The thick dildo stretched her tight cunt wide. Every thrust made her tits swing and her voice crack. "Harder, sis, wreck my hole." I pounded until she collapsed, shaking through another orgasm.
Later she rode me, grinding her clit against the base while I sucked her nipples raw. We switched, and she fucked me with the toy until I squirted across the sheets.

We fell asleep tangled, sweaty, and covered in each other's cum.
By morning we were at it again in the shower, soaping each other's bodies and fingering until the water ran cold. No guilt, just raw need. We knew we'd keep going. Sisters who fuck stay sisters who fuck.
