Of this not a word to your mother

The father warns his son that it is better not to talk about what they are about to do. and it is that while his mother thought that father and son worked together and taught him the trade, in reality what they did was fuck. as soon as the man went in there with the boy his cock grew hard as if he were 18 years old again, and he owed it all to his son. so they always went when no one else could see them. the boy was quite obedient and did everything the father told him to do. if it had been work, he would have been a good worker, but he only wanted him to fuck.
