Cucked Moment

I felt incredibly cucked when my femboy friend I knew jokingly made a comment about my gf, basically saying shit about tying her down and knowing she’s a bigger perv than I and I shouldn’t stop her… I told him to stop and he did and said sorry but I got a weird boner from it and i feel weird— now having thoughts of him fucking her which is getting even worse and I don’t know how to feel

comments are appreciated
