My stepdaughter seduced me

When I saw my 18y.o. stepdaughter sunbathing naked I was both mad at her and extremely horny. A thought of scoring on this fresh slut while living with her mom and comparing who's the better fuck gave me a massive boner and she noticed it. Next thing you know she's on her knees sucking my dick like I couldn't even imagine. A few days later I banged her and boy, what a magical tight pussy she has. Now I'm fucking the whole family!
