This is a lesbian movie starring two of the most accomplished actresses in the JAV realm. Unlike other "lesbian" movies, there are no dicks in this movie, not even limp ones.

Mariko Sada is a maid who is totally lesbian. After her breakup with her long-term girlfriend, she has to resort to making her own artificial vaginas to masturbate with.

She applies for a job as a live in housekeeper for a businessman and his beautiful wife Ririko Kinoshida.
Mariko develops a crush on her mistress and tries to peek at her nudity whenever she can. Ririko is quite open about her body and does not mind the maid seeing her.
When her husband travels, Ririko engages a paid escort to come over and fuck her. Mariko listens to her moans through the closed bedroom door and masturbates.Mariko then steals Ririko's panties and masturbates with them, and is caught. Ririko offers her pussy to Mariko if she promises not to report her extracurricular activities to her husband.
There follows an intense lovemaking between the two women.

Ririko's husband comes home to announce yet another trip. Ririko tells Mariko he is on a trip to fuck his secretary and takes Mariko to a spa. There, the two indulge in yet another super session.

Back home, having got Mariko's promise not to report to her husband, Ririko is back to her old ways and engages the escort again.

Any more would be a spoiler.

For me, the beauty of this movie lies in the two ladies who are not lesbian (based on their other movies) yet they seem to enjoy making love with each other. Their expressions of joy can be simulated, as can their orgasms.

However, the rapport between the two women cannot be faked. Keep an eye out when Ririko is masturbating Mariko and look for the eye exchanges between the two. When they are making love - I would not call it fucking - their facial expressions, their smiles, their eye contact are what makes this feel like genuine emotions.

Well worth watching again and again.

Another thing to note is how Ririko's body changed between JUL-668 when she was a BBW in 2021 and this movie made in 2023 when she has slimmed down a lot.
