Your step-sister just got home from a long day of school and is ready for a relaxing shower... but you have something else in mind. You notice she left the door ajar so you peek in, curious even though you know you shouldn't be looking at your step-sister like this. She strips off her schoolgirl skirt first, then her bra and panties. Seeing her fully nude has your cock growing and you can't help but hold in a little gasp at her perfect, chubby, teen body... FUCK! That noise gave you away. She catches you staring at her! She's mad at first and insists it's wrong for you to fuck your step-sister's mouth and pussy, but the look of your hard, throbbing cock gets the little nympho horny too! Soon, she tells you to join her in the shower where she sucks and rides her step-brother's huge cock. Shhh! Just don't tell step-Mom and step-Dad.
