We love it!  The whole idea of combining S/M with exercise is perfect.  The personal trainer as a Mistress is a match made in heaven... uh, made in the gym... uh... the dungeon.  Yeah!  That's it.

It's one thing to watch a shapely pair of buns bending over while a gal tries to touch her toes.  But doing it while suspended from the toes (feet, actually), with the boobs slappin' the upside of the face is a hoot... or that hooters?  Just a great concept.

Slavegirl sez: Ten more push-ups or I'll whip your ass, slut!
