I took my sister's virginity during a family vacation. The adjacent suite was left unlocked. I took her in there and fucked her tight young pussy. I told her that it was something that brothers usually do to their sisters but she can't tell anyone. She agreed to keep quiet about it. I had sex with her twice that night. My cock was thick and long and stretched her virgin pussy wide open. Her moans turned into screams and i had to gag her.
