Set up all nice and exposed on the gynecology chair, Hinako's sub is in for a world of pleasure/pain when she busts out the sounding tool and sticks it in his urethra. She later yanks it out with her medical tools. Next is the other hole, of which Mayuri, Hinako's shemale friend, assists in shoving a big dildo into. The technique was impeccable, causing the sub to ejaculate profusely.
