*use of taboo trigger word* *virtual sex only* Your sister comes back inside from doing yoga, and you can't help but stare at her ass when she bends over to grab a snack. When she goes to shower, you peep inside, perving on her until she catches you. You run off to your room, but she confronts you about it, telling you she knows that you have been perving on her for awhile. She drops her towel and tells you that it's your chance now, to finally fuck your sister. She lays you down to ride you. She wants her brother just as much, even though it's wrong. You fuck her in cowgirl and missionary until you pump her full of your cum. She loves her brother so so much, and she definitely wants to keep doing this with you. Let's hope no one finds out ;) Keywords: brother x sister, taboo, family, virtual sex, pov, roleplay, brunette, small tits, dirty talk, confrontation, caught, creampie, tease, cowgirl, missionary
