Hitozuma Netori Sharing ~Yamete Otto no Mae de Kore Ijou wa...~

Keigo and his wife Reiko are moving from their small apartment into a huge, ritzy mansion, but they have to share it with the boss and his wife. He's isn't happy about sharing a house but figures they can move out once he succeeds, planning to let the older couple hear him and his wife being intimate until then.

When they move in, he meets the boss, Youzou – a bald middle-aged man – and his insanely beautiful wife, Yuri, who is exactly Keigo's dream woman. That same night, Youzou drops a bombshell: he can't get it up anymore and asks Keigo to "share" Yuri, so she isn't deprived.

Keigo jumps at the chance. He's thrilled to have another man's wife right in front of him, intending to possess Yuri completely – body and mind. However, behind the scenes, another kind of "sharing" and "taking" is about to begin.
