When I told your wife to dress like a dumb slut for our date in front of you, she giggled and looked at you as if this was nonsense. I bet you were pretty surprised, when she started to change the next day, right?
You have strong arms, so you thought it would be a good idea to challenge your bully to show your gf what a man you are. You were wrong. Your bully knew what he was doing. You paid a high price for your loss.
