Yura and her husband were living a happy life until one day the husband invited two close friends over for a drinking session. They all drank a lot that day, but due to his low alcohol tolerance, the husband passed out and knew nothing, while the two friends had to stay overnight at their friend's house because it was too late. Seeing his beautiful and voluptuous wife, one of the friends sneaked over to the bed to touch her. On normal days, the husband couldn't meet the needs due to his erectile dysfunction, so when he found out about the friend's intentions with his wife, she didn't resist, just showing shyness to hide her own lust. The next day, the husband, who had set up a camera in the house, turned it on to discover his wife's affair in a very pleasurable position, but he was not angry or upset at all. Instead, he continued to invite the two friends over for another drinking session. This time, he pretended to be asleep to observe if the same thing would happen as before, but when the two friends started to make advances towards his wife, he woke up and made a very surprising decision, supporting the friends to engage in a threesome with his wife enthusiastically.
