[M4 f & hung bull] I’d like to do a cuck/cheating roleplay [m4f][m4m]

I’ve got some ideas but would love a group chat roleplay. I’m open as well if you have any ideas too. Something I’ve wanted to try for awhile. Even open to the girl playing my actually gf if you like that idea. Maybe something like me catching her cheating or maybe she gets seduced by another guy and wants to make me envious of him.
