Jun Fujisawa, a divorced woman seeking work to support herself, applies for a job at a low-end brothel. She undergoes breast size checks and genital sensitivity tests by the staff, then thoroughly learns professional erotic techniques, including deep anal licking. Her first customer receives tongue kissing, ass licking, nipple play, and handjob, climaxing in intense pleasure. With younger clients, she extracts cum using tight anal licking and lotion-assisted handjob techniques. Regular customers are satisfied with her expert blowjob skills performed on all fours with her back arched. As a special service, she engages in full intercourse, riding vigorously in a wide-legged cowgirl position, driving men into convulsions and guiding them to ultimate ecstasy.
