wow 70s porn music to start playing. Not just one or two buttons but ALL of his buttons just happen to release? Now I will say that if his shirt was silk or satin, I guess it's possible. I just think this is one of the times they should have gone the cookie cutter route and had them arguing, he says something insulting to her, she goes to slap him and he grabs her arm--they stare at each other for 2 seconds and then kiss.
They are consenting adults. Clearly they both had some pent up aggression and this is how they chose to release it. I haven't watched today yet but Nina can't have anymore children so unless he has super sperm, this isn't going to be a ONS. It's going to happen again. I bet my bottom dollar.
