The scheme involves substituting fake ECGs obtained during bondage-domination leather sex. Jimmy's girlfriend complains that Jimmy in unreasonably delaying his orgasms and tries to teach him a lesson.

She massages his cock rock hard and demands he promise to come as quickly as she demands, now and forever.
He nods and she inserts him inside her sex. They pump and pump, intent on him climaxing into the ECGs. She feels her orgasm beginning when-Will there be something to celebrate at the end? Will the celebration be what Carter's wife is hoping for?
