The stepfather saw him masturbate, things got out of hand and then the other stepson added

Surreal. first the stepfather catches his stepson jerking off in bed and things get heated and they end up fucking. so far more or less it is something that can happen although it is still a very morbid situation. well, after that stepfather and stepson opened the season and that great fuck was repeated on other occasions, until the other stepson caught them on one of them. things are starting to get stronger but it's even stronger when that stepson joins the party and they end up having an incestuous threesome between the stepfather and the two brothers.
