[M4F] Size Difference. BDSM. Two characters

(In this rp, I can be a sub or a Dom. Whatever you like to play. Ideally you'd be comfortable with bi male action and kinky. I only play in first person and not into animated characters. I can be the single guy or play the couple)

A couple and the single friend that always tags along are meeting in the single guy's home for dinner and fun. They have ate, drank and played, however things went extreme as they have brought up how I'm still single. We talked and talked until my friend hits me with a comment "I doubt you're big down there". We then get into an argument and the gf would say to get naked so she can decide.

What happens next is your choice.

Some ideas:

1- I am indeed the smaller single guy, in which I'd be forced into being a bi boy submissive for you both. (You'd play both roles)

2- I am the bigger guy and your gf would submit to me while you get cucked and fucked. (You'd play the gf for the beginning and then I'll take over)

3- Your gf would not want to hurt either of our feelings, but she'd coerce us into bi play

4- your idea
