I enjoyed this story because it features a fucked-up, sadistic nonbinary person who can read people’s thoughts and a mysterious, horny girl with unknowable thoughts. Mainly I love the how the main character is so casually cruel sometimes, and I love the main duo’s dynamic. Honestly, the sex is relatively vanilla, and the only slightly BDSM-tinged aspect is how both parties in the main couple (nb/f) consensually exert mind control on each other and battle for dominance. (I should read more switch/switch couplings, since this was so fun.)
The characterization is very good, and the writing in general is clear and strong. I feel like an English teacher grading a paper, but it’s true — the mechanics (grammar, syntax, spelling) didn’t get in the way of the purpose of reading it.
(Also, re: incest: The emphasis of this story is on two perverted mind-controllers trying to top each other, not on the fact that their father figures might be getting engaged soon. So it’s probably safe to take a look even if you generally hate incest, like I do.)
Disclaimer: I only read the first five chapters. But they were really good. I hope you have fun with it.
