Ello everyone ive been searching for this book for a while now and i read it sometime last year. But what i can recall it was of a guy who signs up to film adult film with other men so he can learn to have intercourse better because his ex had said he was bad at it. The adult film company sends him to his favorite guys and there is three. An older man, and a married couple. They welcome him in and they film all weekend long. I remember at the end of the book the mc married the older man
