...My sister-in-law looks at me really coldly.
However, I am panting and suffering with mental anguish over the sister-in-law in my new family.
I couldn't stand it anymore so I decided to do night-crawling on __/__/20__.
If I am found out she will look at me even more harshly, and treat me as sheer waste.
I need to have sex with her without being found out.

My sister-in-law always berates me, saying "you are disgusting! Dirty!
