I try to use some form of punishment that, once the sub relinquishes control (or the attempt), will begin to feel good.. Like a finger or random (sanitary/non-abrasive) item in the bum.. Fuck gently, or rough.. Especially fun on female subs.. When they begin to drip and moan I tease them about how horribly slutty they are to enjoy such a humiliation at My hands..

Anything that you know they can enjoy once they give up their 'tough-guy' act.. Like rhythmic flogging, caning, etc. will usually get females all drippy and wet..
