My father remarried and I suddenly had a cheeky gal sister. Without even a word of greeting, she started teasing me, a virgin, with her defenseless panty shots from the moment we first met! Damn! Even virgins have human rights and sexual desires...! Unable to resist, I took the plunge and fucked my big-assed sister right away! I rubbed her big, round, fair peach ass and made her cum over and over again with my desperate piston-like thrusts! Then I came inside her until she changed her attitude! My dick has completely rehabilitated her!
