Step-Daughter Studying Fantasy

I never thought I'd be lucky enough to have a studious & nerdy stepdaughter, but that's just how Penelope turned out! She also turned out to be quite a sexy little teen, but that's neither here nor there. Until I catch a glimpse of her cute panties, it sets me off. I'm only her stepdad alright!? I start thinking about pulling out my big cock and jerking it, she responds by gleefully rubbing her soaking wet pussy. She gives me a great boobjob with her perky little tits before blowing her stepdad like a responsible young woman. I take her little teen twat from behind, watching her cute bum bounce against me. She likes it rough, so I pull her hair. I flip her around to pound her pussy in missionary and gag the little pervert, but just a little. She lets me cum all over her face. Or wait!? Did I actually pull it out in front of her? Fuck my wife is going to kill me...
