Hello people I'm very new in this whole thing and it's getting me so Horny. I got a girlfriend we have good sex and she likes it a lot but I would love to see her getting fucked by other guys and making me a cuck or cheating like that.

But I don't know how to get her doing that. Can someone help me out or give advice to make her doing it or giving her the excitement to do it.

Greets people hope someone can help me
