Pretty young Marilyn Crystal is very excited about her date. She and her boyfriend have a sexy night planned and she has even bought some new underwear to make it special for him. She looks the new outfit looks good, but really needs a second opinion. The only person at home is her shy stepbrother. He is sitting alone when she comes into the room in her heels and revealing lingerie. She has his attention immediately and asks if he thinks her boyfriend will like it? Does it show off her ass nicely? How about the shoes? Are they too slutty? He is speechless, but the bulge in his pants tells sister exactly what she wanted to know. The outfit is perfect and shy brother wants some. It turns her on to have him staring at her that way and she decides that seducing him is the perfect warm up for her big date. She sits in brother's lap and takes his cock out. He is embarrassed at first, but her soft hands on his shaft relax him as she compliments him on his big, hard boner. She starts sucking it and notices that he can't take his eyes off of her tits. Slipping his dick between them, she rubs up and down, begging for him to fuck her long and deep. Before he has a chance to tell her how wrong it is, Marilyn is on his lap, wiggling her sweet pussy down around his cock. He pumps her hard, but she stops him before he can cum. She can't have her boyfriend noticing so she sucks his hard dick until brother explodes into her mouth. Marilyn swallows it all and promises to do it again if he can keep it a secret.
