My wife [21] is turning me [28] into a cuck.

So for the last couple of months my wife is getting more and more into the idea of getting railed by other men and it is the biggest turn on to me and I am very open to the idea.

I'm not exactly sure when this began but I would have to assume it has been a fantasy of hers for a while, and the fact that I'm a relatively short guy with a penis that just about makes the average cut might have something to do with her wanting to not only humiliate me but also herself.

During sex she only ever talks about how she wants to cheat on me with a tall muscular alpha and how his cock is so big it's the best satisfaction she gets. She talks about this men by using terminology like "king" "bull" "alpha" "real men". She loves fantasising about gangbangs, eating assholes, sucking manly balls, kissing their feet, stepping on her head and so much more. She loves the idea of being so humiliated and that there's nothing I can do. Lately it has gone to another level, while jerking me off she talks about all these things and has added me as part of the humiliation. She wants other men to force me to kiss and suck their feet while they fuck her, she wants me to be up close to his asshole while he fucks her and sniff his asshole and balls. She's even said she wants his big manly cock to rub against my face and his balls to slap my face while he fucks her in her ass.

I don't think we will ever go as far as doing anything like this but I have realised lately that she has been playing an online game with another guy and he has asked her for her Instagram. She told me about this and assured me she just wanted to play online with him.

Before I finish I would like to ask if it's wrong to bring him during our session and see how she would react. Please let me know if you have any thoughts on this.
