It's fall and time is perfect for doing outdoors exercise.  Mrs. Maryu is always excited to do some jogging especially during the end of the year holidays.  After jogging she goes back into her apartment to find the slave slacking and loosing time.  He knows he has cleaning duties so she gets upset and orders him to lay on the floor for him.  She will continue her workout on him with her sexy Nike airmax sneakers and running pants with sweatshirt.  She repeatedly stomps the slaves balls and cock and grinds them under her ribbed soles as she fully presses, making a strong effort and toning her legs.  This of course means more pressure on the slave's cock and balls.  He feels her power and begs for mercy but she is in no mood for it.  She trample him while ordering him to stroke his cock for her.  When she is pleased, she comes back and continue stomping and kicking his balls.  He is later ordered to the cockbox where she intends to fully step, full weight, on his cock and balls until he cums for her.  The slave endures about 10 minutes of pain until he can't hold it anymore and shoots a massive load under her sneakers, which she of course crushes and walks away to take a shower.  Now the slave has to clean his juices from her sneaker soles and shoeprints on the condo.  Don't miss this video since it was shot with two cameras, one with a special rig attached to the mistress, showing you her full POV of the entire action and the other from the slave's POV.
