SUKE-127 Natsuki-san's salary negotiation turns into a hands-on lesson in ejaculation management

Natsuki, a woman said to be one of few in Japan, meets men who have sexual problems. The manager teaches sexual techniques directly, covering kissing, handjobs, nipple licking, blowjobs, paizuri, cunnilingus, and multiple positions including missionary, cowgirl, and back riding. Restraint, spanking, and a facial cumshot with cleaning blowjob are part of the session. The project documents underground professions by interviewing women and engaging in sex while discussing their work and worries.
