I don't get it. The most logical move there would be to cut off his dick. It'd be fucking demented, but it makes the most sense at that moment.

Idk when I had a crush on another dude and saw him fucking his sister, I had plans to hurt her but ended up sexing her instead when I saw how irresistible her pusy was

Nah, technically it works because she is showing the other girl that the boy doesn’t have “real” feelings for her. At this point, if this nutter is smooth enough, she can swoop in and both girls can bond over both being “betrayed” and that actually, the boy doesn’t deserve either of them, and you know what fem-san, fuck boys, we got fingers and tongues, we understand the female wants better and I think you’re pretty cute actually.

Check and mate (not literally, because two holes can’t create life).
