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!
This lady knows how to have sex. I see she picked a stallion that's fit, and he's got a nice dick. Of course, lush-breasted already fucked, but all because she's appetizing, and her holes need a daily shake. A whore like that can't refuse a thing, so I'd give her a hard-on first to show her who's boss, and then I'd give her a mouthful. But the kid's young, he'll eventually learn how to put a lady like that in her place.
