Making a threesome with a complete stranger

The couple was manifesting their love and getting involved in a lonely alley when a mature man passed by. the uncle couldn't take his eyes off that scene, maybe it reminded him of him when he was younger and he got involved with any other boy. he passed by but could not avoid continuing to think about it until he decided to return. the youngsters had seen him and when he saw that he was coming back and that he was also talking to them, they were a little surprised, but what that mature man proposed to them made their cocks even tougher. the man invited them to his house, and once inside he told them to sit on the sofa. they obeyed and sat down while they continued kissing while the mature man watched. it was clear that the thing was going to end in a threesome with that stranger, but that made them horny. in the end you can imagine that the three of them undressed and began to fuck in a group until the mature and the other boy came over the youngest of the three.
