CRS-004 - The Wife Who Became My Puppet: Retribution for Infidelity

A happy ending in this series is unexpected. Even if he can't be too harsh on his own wife, the second half just fizzles out into a normal marital sex scene before you can even tell if the punishment is over or not. Akari Minamino, playing the wife, gave such half-hearted responses that she didn't even feel like someone involved in an affair. Honestly, I applaud Natsumi Kato for working hard to play the weird role of the woman brought in just to have sex in front of the wife.
