Blissful Genuine Sex: Penetration! (1995)

"A sensual drama with a dry touch about a lethargic put-upon young man who indulges in a haphazard relationship with a group of women."

Shuji, an unemployed young man, has been living a haphazard and lethargic life, cheating on his wife with his girlfriends and constantly asking his best friend for loans. Then one day, Shuji takes a train and arrives at a country town. There, he meets Sachiko, a woman who never smiles, and starts working as a live-in employee at the printing house where she works. Shuji has a lot of emotionless sex with Sachiko.
