The girlfriends wanted to learn how to twerk, so they found a lesson on YouTube, dressed up like whores and started shaking their asses. And everything would have been fine, but the stepbrother of one of the girls came home just at the moment when these bitches were standing doggy style. Fortunately, the guy quickly got his bearings and fucked both of them. It's good when your sister is beautiful, but when she's a slut it's even better.
