Nanji no Rinjin wo Aiseyo

A young man lived a quiet life in his apartment, until one day a cute girl moves in next door. Soon after, he learns first-hand how deceiving first impressions can be. Because of the thin walls, the young man can hear sounds of pleasure and ecstasy come out of her apartment every night, each time the young woman enjoying herself with different "company." Turns out, she is a total slut!

Tired of the constant noise, and no longer satisfied with mere thoughts, the young man storms off to her apartment in hopes of finally making his nightly fantasies into a reality.
