I already posted this earlier on a different account that got banned. I 20M have recently developed a cuckoldry kink and really want to see my gf of 3 years have sex with another man. For context I am not small or anything I am 6 foot tall and have a 7.5 inch dick, she has told me many times that she is very satisfied with me and that she would have sex with me all day if she could, she has an incredibly high libido and we joke that she is addicted to sex. About my kink I specifically want to see her with a much bigger and stronger man, I want to see him take control and completely dominate her in front of me, I also want her to humiliate me and make fun of me while he's fucking her. The problem is I am scared of telling her and ruining out relationship. I am not sure what to do and could use some advice. Also let me know your thoughts on this kink. Am I just weird?
