Wow, this was well described. I wish all wanna be Cucks would read your post and ask themselves, “Are you ready for this to happen and feel this way ”. If you can, then go into it with no regrets but don’t be upset when it happens.
I would be considered a BBC (not huge but well endowed) and I feel like I’m very good at sex (physically and mentally) but even I know I can get outdone by a bigger dick with more experience that can make my gf feel things she has never felt before. I’m no dummy, although I know she would want to have sex with me, I know when a person makes you feel a certain way, you yearn to feel like that again and there is part of you that wants that again.
I don’t want my girl feigning for another man as we have sex. I’m not feigning for another woman as we fuck so why do I want her doing that with someone else.
