My gf (F18) is forcing me (M19) to become a gay slave

# My gf is very dominant, last week she admitted to cheating on me but she said she didn't regret it and she told me the other guy was making fun of me while they fucked and it turned her on. I cried but she said that she was growing as a person and I can understand that. Thankfully she isn't going to break up with me but she wants me to be a gay slave to another man it is a kink for her she never realized before. I asked what she meant and she said it could be virtual as long as it was on FaceTime, she wants me to cum on the floor and lick it up, do toilet stuff, or do anything else the other person wants. I told her I'm not putting anything up my ass she said it was fine. I would never leave her I have to do what she says.
