"What? The cause of cheating is his big dick?" When Izumi was consulted about her husband's cheating habit, which has not changed even after marriage and is getting worse, she was shocked by the unexpected reason for the cheating. That can't be. Izumi was furious at the lame excuse. "Then why don't you show me your cheating dick that you are so proud of?" It was obviously a lie to get out of the way.

Izumi was Kokoro by the shining black cock and started to devise a plan to relieve her frustration.
