He fucks his own brother to wake him up and do him a favor

The blonde in the video needs a favor and that implies that her brother wakes up and lifts her ass off the bed. But he knows how difficult it is, so he fucks his own brother to get it. He starts touching his cock when he sees that it is hard, he sucks it and thus he gradually convinces him that if he wakes up he will have an incredible reward. The reward ends up being not only that he puts his cock in his mouth, but also that he fucks her really hard and enjoys a powder going through his little sister's tight pussy.
