Wife vs. younger sister in law

[Naughty69M2M]

I have an idea for a story where a wife gets into a series of arguments with a much younger...like 10 years, sister in law. Eventually the sister in law finds a way to dominate her older brothers wife. Can't decide if they should fight or if some other blackmail angle should be in play. Also can't quite decide why they are always fighting. Any suggestions would be appreciated.

The always fighting bit is easy: Sister-in-law got divorced, is kicked out by her parents, is job-hunting, etc. and moves in with her brother and his wife.

Blackmail is one way to go, she discovers wife had an affair at some point or lied about where some money went.

Alternatively, wife is sexually frustrated. She used to just go home, rub one out, and then maybe charm her husband into bed. Since sis-in-law moved in, she can't get much tie to herself and her husband is making love to her less often.

During one fight, sis-in-law snaps and pushes over the kitchen table. She spanks her bum red and then, after she calms down, she leaves for a couple days. Wife meanwhile keeps the incident a secret but can't help but remember how it felt and even fantasizes about being taken by her sister-in-law.

She invites her back and they talk about the incident. Wife tries to dance around things but sister-in-law sees through her bullshit and starts teasing her. Wife reluctantly admits to her attraction but doesn't want to give herself fully over. Sis-in-law comes up with a deal: wife stops complaining about her staying with them and keeps things a secret...and sis-in-law will become her dom. She further incentivizes her by telling her that there's a lot more to being dominated than just the humiliation and spanking. The frustrated wife relents.

Over the course of the story, the affair either remains consensual on both sides or maybe the sister gets her to fuck someone else and records it.

The ending could be that the affair continues, the wife is caught and has to decide what to do, the sister ruins her marriage and life while making her a complete slave, or maybe the secret is revealed to the brother and he allows it to continue, either by his own choice or because he can't say no to his sister.

Thanks SB. the sister in law moves in after college and other job.......wife's now unable to rub things out and doesn't feel comfortable having the plain sex with her Hubby. Tensions arise after the little sis discovers her sister in laws toy collection, knowing her brother would not approve. They argue and the wife gets spanked by the sister inlaw. Kind of like your idea of her leaving too and the wife thinking about it over and over.

Ahhh...the younger sister in law goes home to visit the parents afterwards.....

Sounds hot.

Maybe things get interesting at a holiday party. That's where the sex happens, in private of course.

Maybe they don't agree because the wife is super busy with her career, and the in-law feels that the wife isn't paying enough attention to him, or she's accusing the wife of cheating.
