Mei works at a men's beauty salon, where she doesn't tell her husband that her finances are tight. However, one day, the father-in-law I hate so much came to the shop and grabbed my weakness. And so the father-in-law's demand for a rejuvenating massage is too much...! Humiliating oil handjob, shameful throat without underwear, sticky cunnilingus climax, threatened NTR sex with cream... In the end, she will be treated as a sex beautician exclusively for her father-in-law, and she will fall into the vulgar scene of a perverted wife demanding to suck a cock and forgetting her husband!
