Catholic says sex after marriage is really ok in heterosexual way. All practices, even pe e in mouth, except for the anal ones.
After marriage if other men fuck her, its adultery mistake, an small sin.
A sin that will be forgiven, hence, nothing really bad happens for enjoy cuckolding and sharing our girlfriends to the pleasure of more men.
I have broken with my girlfriend a small time ago, a filipina who was not in cuckolding. I need to find a new one.
