At first, Marty had “trained” his daddy boi toy at home. But little by little, the young master had become more demanding. Paul would have his obedience tested outside Marty’s home, like that time in the dressing room of the local gym. In spite of his protests, the erstwhile top would have to kneel on the floor and orally service his new “boss”. Of course, Marty picked a time when nobody was around, and Paul was aware of that, but still, the mix of excitement and humiliation would get the older man as hard as a rock. He was strictly forbidden to touch himself, but Marty thought he would have to look into a suitable chastity device for his daddy boi.
