They were curious to know what a real man's body was like, and for that no one better than their father. they called him dad despite being his stepfather, and he was quite a well-muscled man. as they looked at him, the mature man noticed and told them that they were going to him. they did and sat on the couch to explain why they were looking at him. it was the man who grabbed his hands to touch his muscles and abs, you could tell they liked that. then they began to touch his stepfather's cock until one of them dared to lick it, he liked that. the other looked intrigued, he also wanted to participate and he did, they saw how he got hard and they got excited, then they showed him their small penises and the man sucked them too so they could see what he felt. then he started the game by telling her to suck each other off, until he penetrated the ass of one of the young men. the other watched as his stepbrother ate it. they liked the experience, and he told them that now they had to fuck each other, they did it while the stepfather jerked off watching them.
