Going for three

[Rob_Royale]

Three generations, that is. Spinning off Sirhugs three generation lesbian post.
A man or woman is either dating into or married into a family. They are in their mid-thirties, and their SO is a little older. The SO has a very good-looking adult child and mature parent. The environment is sexually charged most of the time with the three generations under the same roof and before long they are fucking one, and planning on fucking the other.
Lots of ways to play this, lots of unusual settings and circumstances that could make this highly erotic. I'm leaning towards some sort of wife sharing within the family.

Not uncommon variation is that the intended has to be 'tested' or 'tried out' by the family to see if they're worthy.


Groom with Bride's sister, mother, grandmother.

Bride with Groom's brother, father, grandfather

Or whatever other combinations and relations.

One thing I've seen often in manga is the wife with father-in-law. And she's seemingly helpless before his lustful advances. He's tall and handsome and in remarkable shape for his age. The young woman marries a man in his forties, his second marriage, her first. Husband travels for work and the honeymoon is barely over before he's back on the road. After just a few days, with her father-in-law living in the same house, the flirting begins. I'd make it a slow burn story where she plays along, thinking it harmless fun, until her walks up behind her in the kitchen reaches around and grabs her breasts brazenly. She can feel his hardness pressed against her ass and she gasps. Her heart is racing and she can feel her pussy getting moist as he kisses her neck. But she politely puts him off and he just chuickles as he walks away.
After a week or so, she's horny and feeling neglected and she gives in to her alpha father-in-law. Vigorously.
When her husband returns for just a few days, everything returns to normal. But just before the husband leaves again, she's introduced to his son, who is the spitting image of the grandfather.
"Junior will be staying here during his summer break from university."
She can feel the young man's eyes undressing her and she sighs. "Wonderful, dear. He is very welcome."

I'd do this in an implausible but fun trad-wife scenario. Very June Cleaver 1950's.
