You have been in contact with your ex-girlfriend and told her about your sissy fetish. Now she is offering you a chance to be her sissy cuck for her and her man. You were with her for so long, so seeing her happy with someone else is going to be terrible for you. I advise against this! You are telling me you have already accepted it? Now you are going to have to go through with it. If you back out, you might find yourself in some real danger!
