Tricked his wife who just gave birth to a friend to have a fuck

This is the first time, all 4 of us took turns having sex with my wife in the second round until everyone was complete. It was almost five o'clock in the evening. When it was done, we dispersed. I noticed that the bed was wet with my wife's milk until it was a big spot. My friends also teased that there was a lot of milk. The next day, I came to suck again. My wife smiled and blushed.
