Another thread brought this story to mind.
Husband and wife are at a neighborhood party. The men downstairs watching football and the wives talking upstairs. He goes upstairs and hears the women talking. The wife then proceeds to trash his size and sexual ability. He leaves the party. Wife tries to apologize but he moves out.
He has a custom motorcycle shop and does custom work for a the head of a biker gang and is photographed for a magazine with the biker's big-titted sister which makes the wife jealous.
Eventually the get back together. At sometime during or after the reconciliation wife transforms herself into the ultimate biker babe in leather with big (non-permanent fake) tits to surprise him.
