What I saw was the guest touching Susan's nipples while they were sharing the sofa. Susan held his hand away but kept returning to the same position so he could touch again. The guest's girlfriend was watching and reaching inside her on shirt and took off her bra...as if to give permission to Susan. The guest got up and opened up to sofa into the bed mode and just as they were settling in again, Hector ran in and threw something on the sofa between them and started shouting at Susan. They quarreled back and forth for quite a while and Susan never backed down. The couple left them alone for a while to sort it out and after very long silence, Hector went to bed and left them alone. Susan thought through the moment and decided to pass and went to bed with Hector. Since then, whenever Hector senses her getting hot for the guy, he gives Susan a some very hard fucking.
