I've noticed you've been stealing my panties and cumming in them as well as taking sneaky naked photos of me and to be honest, it's been turning me on. So when mom and dad leave for the weekend, I come into your room while you're masturbating and make my move. I grab your cock and start stroking, sucking and giving you a titjob, telling you what a naughty little brother you've been. Your cock's getting really hard so I sit on your lap and ride you hard and rough, telling you to spank me. You're nervous at first but soon start fucking me back, which gets me turned on even more. You admit that you fantasize and watch sister, mommy, auntie porn so I decide we should roleplay. I'll be the mommy and you be my son, and I want you to keep calling me mommy until you fill my pussy with cum!
