Hey guys need help finding a doujin I read a while back
Sorry for bad details but what I remember is that the wife and husband agree that [,through hentai logic,] a bunch of guys need to sleep with the wife in order to help their marriage and she's recording it and talking to the husband throughout the video. The sex acts escalate until the final part where she's sitting on a bench and there's a line of guys leading to her who will creampie her (which they didn't earlier until that point)
She had shoulder length hair (I believe) and was busty and such

here's a pic in thanks already for the help
