Sierra is so hot, I can't help myself but spy on her. She's also my stepsister, but that's just a small detail. She's talking to her boyfriend, they never have sex and she seems frustrated. She hangs up on him and goes to have a shower as I watch her get her teen body all wet and sudsy. Once she's done and she thinks nobody is watching her, she goes to her room and starts rubbing on her pussy. I play dumb and walk-in & she covers up quickly! I guess she was feeling insecure becasue she did open up about her relationship and how they weren't having sex. She asks me to rate her tits which makes me spit out my water. She has really nice tits, perky! Then she wants me to squeeze them, it's way too much but I go along with it. She keeps encouraging me so I start making out with her - fingering her pussy & sucking on her tits - she goes wild, she loves it! She gives me a sloppy blowjob as I f-rce my big dick down her throat. She climbs on top of me and almost starts cumming instantly as I fuck her hard, so many orgasms! I get her in missionary while she rubs her teen pussy, she keeps begging me to creampie her so I go with it and cum a big load inside her. Sierra is not feeling so inescure now!
