Yuki Mamiya (Yuki Masuda) nude scenes in The Key – Professor’s Pleasure

Yuki Mamiya is one of the most reliable actresses in Japan when it comes to nudity.

The star has spent a decade or so doing both nude shoots and nude sex scenes in movies, both low-budget sexploitation and more mainstream erotic films.

Examples include The Crawler in the Attic, Sweet Whip, Chotto Kawaii Iron Maiden (aka The Torture Club), and Wet Woman in the Wind.

She used to perform under the name Yuki Mogami and now apparently goes by Yuki Masuda, which is how she is credited for The Key – Professor’s Pleasure.

We missed it at the time but this erotic, which came out in Japan in 2022, has several nude sex scenes with the lovely Mamiya/Masuda.

It is adapted from a Jun’ichi Tanizaki story and also stars Mone Akitani, who recently gave us her own nude debut in a sweaty sex scene in Futon.

In the The Key, Mamiya plays the horny thirtysomething wife of a man in his forties who is unable to satisfy his wife’s sexual desires.

Mamiya has several nude scenes, all confined to a conventional bedroom setting. She has sex with both her older husband and a younger, more virile lover.

Mamiya/Masuda is still only 33 years old and we hope has many more years of acting in movies like this ahead of her. We have always found her lips and mole super sexy.
