I catch you perving on me whilst I study... I'm so angry at first! Threatening to tell everyone how much of a dirty perve you are,spying on your sisters friends! I give you the option to either show me your cock or I tell... You hesitate but agree... I can't believe how big your cock is and I become so horny and wet , that I just have to show you my perky breasts and little pussy. I'm super shy at first as I've only ever seen pornstars perfect pussy and hope that mine is just as good! I bend over and allow you to rub your cock against my ass for a little while and then we start to both masturbate together. I then countdown from 10 and we orgasm together... you swear to never tell anyone our dirty little secret!
