Having sex with your sister in law is completely deranged, right?

It probably depends on how much you hate your bio parent and stepparent. If eg I was a Chadly 16 year old and a drunk, verbally abusive stepdad moved into my house with me and my mom, and he brought along his hot 15 year old daughter, I could see how fucking the shit out of his 15 year old daughter might be beneficial for me and my mom.

I do but I prefer fantasizing about my non-existent step sister. I originally meant to go back to the beginning of this and add some intro that set up the pivot, but I forgot to do that.

Given the XO stipulation that we’re limiting the discussion to wife’s sister and brother’s wife is obviously off limits, it would require a wife that is truly evil and awful to justify it, and no kids can be involved for anyone. That said, it would be literally the greatest spite sex ever, if justified, and also a real life-threatening peak experience since by definition any wife awful enough to deserve to get cucked by her own sister would be fully capable of murdering both of you. So in that 1/100k scenario where you made the mistake of marrying the literal devil it’s not only justified it’s incredibly hot.

Not sure if this analysis is on point. The less it's justified the hotter it is imo

Scandal is the very foundation of the SIL Fetish

Anyone who doesn't at least understand the temptation doesn't have a hotter young SiL.

It's a combination of many factors. She's a hotter, younger version of your wife (who you were already naturally attracted to--they share the same genes).

She's often proximate to you including during revealing, semi-intimate moments--e.g., lounging around in her robe, changing adjacent to go to the beach, at the pool in her bikini, at a cabin getting dressed in the morning, casually walking into your room while you're getting dressed, asking you to pass her a towel, etc.

The SiL has a natural temptation and desire--this can be conscious or subconscious--to fuck with her sister like all good classic fucked up female relationships and one obvious way to do it is to tempt the sister's husband.

It's a toxic stew that results in you constantly having a throbbing cock around your SiL's pendulous breasts and warm luscious hairy honeypit that she semi-regularly flashes you with even as your rational mind tells you this would be the worst decision you ever made because inevitably it will come back to haunt you and blow up your life.

Thank
