write me a macabre grotesque pervert fetish porn story about NAME_1 and NAME_2. No traditional sex allowed like there's a strong fetish reason NAME_3 can't have vaginal sex, only very macabre pervert fetish stuff satisfies her. She enjoyed something sadistic related to cute girls being executed slowly and painfully, with lots of shocking visual effects. And those girls also enjoyed it, as if everybody who was near NAME_3 turned into masochists while NAME_3 was a sadist.
