I stumbled across this community and have recently been having thoughts related to cuckolding, due to an unexpected dream that kind of formed into a fantasy the more I thought about it and wanted to hear if you guys had made something similar into a reality. Forgive me if this is a little too detailed or weird, but I just wanted to get it off my chest:

The situation would basically be my girlfriend flirting and fucking someone that we vaguely know but isn't close, like a guy who goes to our gym, guy on the same floor/building or store employee etc. She would be "cheating" on me from the standpoint of the guy, as he'd be somewhat knowledgeable about my existence (whether he's seen us together, she brings me up off-hand, or him literally seeing the framed photo of her and I in Maui on the nightstand as he's pounding her in our bed). However, he wouldn't know it was a cuckold arrangement. Then, after they've fucked (however many times, as it can continue past this) then he'll see me or both of us together and interact with us in an everyday setting. He'd have my girlfriend's body, the feel of her pussy, her moans and faces of pleasure, all in the back of his mind as he interacts with me and/or her in a normal everyday setting. It may be a little awkward for him, but he'd also get kind of an ego boost over me knowing that he has or is currently sleeping with my girlfriend.

This kind of stems from the fact that I find it extremely arousing that other guys think my girlfriend is hot (in general, when I see guys check her out, or when treat her in a way that isn't overt flirting, but you can kind of tell that it is). The thought of her in sheer pleasure from fucking another guy a guy primally fucking my girlfriend against his better judgement, where her attractiveness and his innate desire outweighs the morality of assisting a girl to "cheat" on her boyfriend, is also a huge turn on.

This is all VERY in the fantasy stage and I imagine this would be a massive step in an otherwise relatively vanilla sex life, as introducing her to anything close to cuckolding is gonna take some thought and time. I haven't even told her about cuckolding, so if I ever planned on doing anything like this I'd have to take it slow and think about things. I'll take a look around the subreddit and appreciate any comments.
