MAMA-212 - Irresistible affairs of married women, mature ladies awakened by their first anal experience

I rented this expecting some lewd mature anal sex, but it was surprisingly average. Some of the actresses were barely pushing the limits of what I consider 'mature.' Because of the 'first time' premise, they keep saying things like 'stop it,' which really kills the mood. It's not quite a humiliation flick either; it just feels half-hearted and mediocre. I heard Chocoball Mukai is retiring from AV with this, but it's a bit sad to see such a big-name actor go out with such a lackluster performance.
