Each person has a different situation and while this guy had money to spare this couple did not have a hard time and offered a deal that after talking between the two did not hesitate. With the money they would offer him to fuck they could go on vacation and that made them want to get into the garlic and go with the boy to enjoy a well deserved vacation.
The two of them had once talked about partner exchanges, and the fact that this guy offered him money to fuck was part of their plans. The morbid idea of selling herself and being a whore made her super horny and the boyfriend watched as she enjoyed a cock that was not hers. She had to give it all and she loved to see her moan with pleasure while another guy blew her to death. Everyone left happy.
