This was less fucked up than what I was expecting (there was another oneshot with a similar setting).
Mind to share a name or link please?
I've forgotten the name (and thank god I did tbh) but the MC's sister-in-law somehow took her deceased husband's er--- family jewels and proceeded to declare ntr as she and the MC screwed each other.
To give some context, the images don't all come from the same tweet, the latter two both come from different, later ones. Apparently the author changed their mind afterwards (the tweet with the third image called it a "questionable continuation").
I never expected to see progress this early when she dreamt about the mum lmao but it's a very welcome step. I thought this was gonna get dragged out considering the short number of pages.
