Help me find this NTR manga wife getting gangbanged
​
It was a long manga. The mc and fmc are married but they don't have active sexual life. So the mc asked the office Boss about it. Boss asked both of them to come to a inn. There were other people and their wives. They were gangbanging others wife. If the wives didn't fullfill certain condition they were punished. I remember a page where two milf were opposite to each other fucking a same dildo.
The mc has sex with other milfs while the wife first refuse but join later.
It was the first premise. I don't remember later half of the story. Can u please find the sauce?
