I can’t remember the name of the book!

Okay so does anyone know this book?... a college girl is tricked by this other girl into going to a place to get an obgyn check up but it turns out that the “check up” is actually a masturbatory study class for women. There’s multiple men in the room and they masturbate her for so long...and it keeps going like this. It got me so hot and heavy reading all of this and I’ve never had such a great orgasm from fingering myself to this. Does anyone know the name of this book or a book like this?
