Introduced by a coworker, personal trainer Yuu Konishi's workout sessions are packed with the exact kind of naughty training everyone's been talking about. She rides the exercise bike with her legs wide open, sucking the cock with each bounce, then mounts in cowgirl position, grinding her hips like rodeo sex before finishing with creampie after creampie. Yuu has a special condition—she can't hold her bladder when she gets too excited. While using the ab machine, she constantly leaks urine, and on the leg press, she orgasms with involuntary peeing. During yoga lessons, she performs gentle bridge blowjobs, and once fully penetrated, she reaches climax in acrobatic positions, drenching everything with her massive peeing. This is truly an extreme, erotic training experience.
