MEL: Kneel back down in front us both and pick up the black felt tip pen, I want you to write "WANKER" along the shaft of your cock
CARLA: Do as Mel say's it will be a reminder of what you are......giggle
MEL: The pen is permanent ink so it will be with you some time, unless you can take the pain of scrubbing your cock........ouch!!....giggle
CARLA: Just think your girlfriend will get to see it, especially when she sits on your face and looks down your naked handcuffed body like last night......
