Things seem to be going well between her mother and Ruby Moons's new stepdad, Filthy Rich - but she is curious. She wants details! How is their sex life!? Have they done anal yet!? Rich is taken aback but decides to bond with his stepdaughter and tells her about some of the more intimate details between him and her mother. No, they haven't done anal yet but they've messed around with some sexy play ass. As her stepfather dishes out the dirt, Ruby secretly begins to touch herself and drift off. She imagines herself sitting on her stepdaddy's lap and telling him that he can have her ass. Rich pulls down his stepdaughter's panties and begins to eat her asshole ravenously from behind - she moans in pleasure as her pussy drips from the tongue in her ass. Her stepdad offers up his fat cock for her to suck. Ruby chows down on her stepdaddy's thick penis and then he thrusts himself into her anxious little pussy. Ruby can't help but cum on her stepdad's stiff dick and thinks she is ready to take it in her ass now. He puts it inside her butt gently and begins to stretch her out. Once she is nice and opened up, Rich pounds the fuck out of Ruby's tight hole - making her cum hard from anal with her stepdad. Ruby even cleans her stepdaddy's big cock off with some intense ass-to-mouth. Once this horny stepdaughter has cum several times, she lets her stepdaddy dump his load on her face. Did she just fantasize that whole thing!? Did her stepdad see her touch herself too!? You'll just have to watch to find out!
