Lady Nina runs an exercise class for her domina friends, usually it's a class for females only but today she has been asked to bring along and exercise an unfit slave owned by another Mistress friend. The Mistress's attending are shocked at his laziness and set to work giving him a very special training session including: being made to do press-ups kissing their shoes with weights on his nipples; they lock a large butt plug into him and make him do a series of squats; wrestle and smother him; tie him to the punch bag for boxing training; and finish by giving him a good hard caning.
