Stepsis obsessed with my dick

My 21 y.o. sister is a slut and that's why she is the best! Not only did the not freak out on me when I started filming her half-naked, but she even let me eat her pussy. Next day she offered me a blowjob and she must have really enjoyed sucking my dick cuz the day after we did it again, only this time I also fucked her. My stepsis is the best! She has a tight pussy, she swallows and she loves big messy facials. Now I feel ready for college life!
