I'd let my wife get fucked too. Just to make sure she's a bitch. Any chick's just waiting for that. That blonde doesn't mind being fucked all over. That dog with the rubber band ain't her husband, that's for sure. And the hubby, as the owner of the chick, fucks her without too much precaution.
Those who think it's not normal, think about it, these are strangers to each other. That's why there's nothing wrong with it. Two adults of different sexes are at home alone, hormones are splashing in both of them. So the skinny blonde was not at all against caresses from her stepbrother, she only broke down for show, but with his insistence his brother showed the seriousness of his intentions, and that this will not go beyond their bedroom. Both are happy at the end!
I'll take a porno.
