When I call a no-intercourse escort service to my home, the woman at the door is Momozono, the plain and quiet office coworker I see every day. She panics and begs me to request someone else, giving me an idea: from now on, she will be my perverted pet. Exploiting her secret, I maul the enormous breasts hidden beneath her modest clothes and fuck her bareback, unloading deep inside her pussy. Her sobbing face and bouncing tits fuel my twisted desire, and that day marks the beginning of her training as my breast slave.
