I found a forum a long time ago where basically there was a post about writing a one shot story and the themes were incest bestiality and group and I remember that the second story on that list was about a football team having an orgy on the bus on the way back home. I can’t remember the website but I know it had a green background and it was in the style of a forum so the stories were all comments
