Yoshihiko now lives with a couple of old friends, a married couple, Ryosuke and Aya. They share a past in several senses. It was Ryosuke who walked off with Yoshihiko’s girlfriend Aya. In doing so, Ryosuke broke up with his own girlfriend, Reiko. Now they are all back together again and old feelings begin to surface.
Yoshihiko reunites with Reiko and Aya and fucks both of them separately several times. Aya is his ex who left him to marry Ryosuke, while Reiko is the girl that Ryosuke dumped to marry Aya. Reiko has a current boyfriend. The sex scenes, especially the 2nd or third time with each female, are surprisingly quite intense.
