Kinky older neighbor introduces two young males to sex

This lecherous daddy has called on his nephews to train them in the pleasures of sex, and sodomy in particular. After some physical training to get them in the right mood, it's in the uncle's living room that the hostilities begin. First, they have to suck a cock, with delicacy and application. Next, it's their assholes that will be exercised, as the two nephews get fucked by the uncle.
