Man Realizing How Kinky/Submissive His Female Relatives Are

[FantasySharer1]

I keep thinking of a multi part story where a man is shocked at how depraved, submissive, and perverted his mother, sister, and wife are. And all in relation to his own best friend.

He finds out his mother is in a piss-slave relationship with his best friend (along with a full romantic, loving relationship). She ensures that her man never pisses in the toilet, only in her own mouth.

He finds out his sister is also his friend's lover, and is in a BDSM relationship where she submits to his friend constantly.

He is eventually cuckolded by his friend and his own wife and learn that his wife his a cum dumpster for his friend.

Eventually he walks into a foursome where his best friend pisses in the mom's mouth for her to swallow, is slapping the sister's ass hard while fucking her, and then ends up ejaculating multiple times in all three of the wife's holes. And he realizes he enjoys being a cuckold.

Hard to believe that all that comes out at once and he never had a clue. But maybe he stays with his wifes family after being just married and finds out about his inlaws.

Yeah I wouldn't imagine it happens immediately. It would be a slow finding out about how kinky everyone is.

I'd start it with a bit of oddness, a visit to his mom's. His friend already there, a funny excited look on his mom's face, an odd small stain on her blouse? A whiff of something when he pecks her cheek on leaving and her nervous laugh? We the reader let into what happened via a flashback perhaps as his friend leaves with him?

How about this?
The man catches his best friend and mother fucking. He's quite shock, but after they talk, he's ok with it. He wants his mother happy and who better than his best friend. Later on, he then catches his best friend fucking his sister! He's even more shock. They talk again, even stating that mom is ok with it! He realizes he can't control their actions as they are adults now. He tells his lovely wife who says it's gross that his mother and sister does this with the best friend.
Wife's involvement:
Either
One day the man comes home early, hears strange noises with multiple voices coming from his marital bedroom. He stealthy goes in and catches his wife getting plowed by his best friend! But not only that, his mom and sister are there too also joining in the fray. Husband watches in awe and has a massive erection. After the wild foursome, wife confess how she loves being dominated by best friend and being his cum dumpster.
Or
They get a visit from mom, best friend and sister or they go over. Maybe they drink and get a little loose. Best friend seduces man's wife. She tries to act as if it's unpleasant, but she's obviously turned on. The man just watches in awe and is also turned on. He keeps teasing and Mom and sister gets persuasive, wife lightens up. Best friend ask the bold question is she wants to fuck with husband's approval, of course. Wife kindly ask if husband is ok with it. A long pause but the man finally says it's ok. They make out and tease each other with Mom and sister joining in. They strip and make their way to the bedroom where the best friend fucks the three women for hours.
