Just let the actors do what they want to do. I think there were actually married couples here, bi guys, it would have been hotter just to see them do whatever they watned to do sexaully, whatever they watned to say, instead of scripting it. Authenticity, not fiction. Please.
It's not gay if your wife forces you to suck another man's cock, right? Because it's for her pleasure. She gets a perverse thrill from watching you demean yourself. You're supposed to make your wife happy, right? Isn't that what marriage is all about?
