There’s this one author I remember liking a lot, but I read all of their stories in one night and never remembered their name, i believe they were either an Ao3 or Fanfiction.net writer.
They wrote almost exclusively one shots, and I remember one story involving a guy almost getting caught getting pegged by his mom (the mom wasn’t pegging him, his mom walked in on him getting pegged) and another story involving a guy getting gangbanged (by girls) in a car.
