Bijin Tsuma, Ichinose Shiori (37) wa, Musume no Yuujin ni Dakareteiru

A housewife caught in a sexless marriage finds relief in the arms of her daughter's best friend... Shiori Ichinose, age 37, is a full-time housewife living in an apartment with her daughter. She's had a long-standing problem, though... Sex with her husband has become far too infrequent!

Her desires are only increasing as she's getting older, so she spends her days venting her frustrations with masturbation, sex toys, and by uploading lewd selfies and videos to her secret social media account. One day, her daughter's classmate and friend, Miyamae Akari, stumbles upon her secret. Akari confronts her on this, and while Shiori is still flustered from the reveal, she follows up with a strange proposal..."I'll be your partner, if you'd like..."

At first, Shiori thinks this must all be a joke, but one thing leads to another, and they have sex... Soon, Shiori realizes that this kind of pleasure is what she'd always been craving!

While bewildered at the prospect of having a carnal relationship with her daughter's best friend, she finds her body starting to lust after Akari more and more... Soon enough, her heart is captivated too...

Thus, Shiori, totally enamoured, surrenders her ripe body to Akari and begs her: "Akari, I beg you... Please make a mess of me..."
