Okay so first off I love that this sub exists secondly here are the details i remember about the story. It starts off with a couple deciding to let a guy watch them and they go online to a craigslist type place to find the guy. When they get him to come watch them he sits and watch and strokes while the couple plays. When the BF leaves the room to use the restroom and get a drink the wife and guy have started playing without him and rather then get angry he gets turned on and watches. I remember the guy CP’s the girl and the husband cleans it up but I am running out of places to look. I think the story title is something like “unintentional first time cuckold” the writing one it is top notch so if the story has alot of errors it is not the right one. Thanks in advance for the help!
