My sister is a super slut and a sadist! I can't resist her as she uses every trick in the book to satisfy her sexual desires. She even restrains me while I'm sleeping and inserts herself, sneaks into my classroom from a different grade to jerk me off, or gets into the bath with me to give me a blowjob using her breasts. There's no end to what she'll do! Even on the day my girlfriend comes over to play, she doesn't hesitate to NTR me. This forbidden relationship excites me so much as a masochist that I can't refuse!
