kek this is the most level headed writing in the entire NTR history. While the writing isn't particularly good (it's fucking appetite), the conclusion is so sensible it made me laugh. At the very end MC got his karma back, the girls knocked him out and tied him onto a chair, letting him watch them tribbing really hard while constantly professing their love to each other. At the end, they counter-threaten the MC with filing a police report for sexual abuse and rape if he proceed to leak their lesbian sex photos to the public.
While his sister isn't particularly a good person because she kinda took the chance and ntr MC's girlfriend, the MC is not particularly a good person either. The gf here is only doing the right thing by dumping him at the end lmao. It is so fucking funny that he thought his actions would bear no consequence and thinks his gf will eventually goes back to him for his dick after raping and blackmailing her multiple times.
In another ending route, it is just your usual cliche ntr ending where they become his bitches. Nothing funny or amazing happen here since there are a lot of ntr eroges with the same endings that have better writing than this trash.
