I dunno what I was expecting but volume 13 is even more degenerately horny than previous. Everyone is turning yandere, I'm only halfway through the book and already we've had
>Oliver and Nanao vanilla cuddling and touching each other
>Guy's kouhai forcing him to grope her, showing off her breasts and propositioning him for sex
>Pete drugging and tongueraping Guy to feed him a paralytic drug and then kidnapping him because he was about to be NTRed from the group
>Pete trying to rape Oliver afterwards only to suffer domination loss (she cummed so hard that she turned back into a guy halfway)
>Katie getting high off study drugs and Oliver hugs and stuck in permanent arousal, Oliver and Nanao masturbating her to climax to treat her condition
