He catches his straight guy jerking off and fucks him

His uncle was a straight man, in fact he caught him jerking off watching a totally heterosexual anal sex porn movie. that is, in which a guy penetrated the ass of a girl. however, his nephew did not seem to care too much, and as soon as he saw him with his cock in his hand he threw himself into it to give him a blowjob. the boy was naked while he was sucking him off, and his uncle was still watching the movie, possibly imagining that a woman was sucking it. but he got much more horny after that blowjob, so in the end they ended up in the room where his nephew's ass finally penetrated as if he were a little whore.
