Considering how much they'd been drinking, I'm not surprised they had the idea to have a threesome. Especially since the mom is such a badass. Kissing your daughter in front of her boyfriend meant offering yourself up as a pussy for copulation. And the guy took advantage of that offer by banging both of them. He even shared his sperm with his mother when he came between his girlfriend's legs. Damn, that's fair!
The sexy chick has very big tits, which the guy likes to squeeze so much and then fuck the beastie with such force that she squeaks with pleasure. It immediately becomes clear that the couple knows how to have sex
