Russian girl played strip cards and ended up having sex

There is nothing to do in the evening, so my stepsister visiting me is perceived as a gift of fate. Yes, she herself is not averse to having fun, and when I offer to play twenty-one, my sister happily agrees. To begin with, I play her around and force her to undress, then give her a blowjob and fuck her properly. And even if not right away, but in the end I fuck my sister almost completely.
