You arrive home to find your girlfriend wearing a really hot new set of lingerie. She smiles and leads you to the bedroom, explaining she’s been wanting to try something new in bed. You are pleasantly surprised, and feel pretty sure you’ll be up for whatever it is. 'I just think it’s really hot watching two men fuck, or having two guys fucking me at the same time!' she says, excitedly. 'I’d love to watch you with another guy. What do you think?' She bats her eyelashes at you, encouraging you to think about trying it just this once.
