write me a porn story about NAME_1 finds a tape and watches a video where he sees somebody fucks his beloved NAME_2 and she moans like a whore begging to be raped. He is shocked but somewhat aroused to watch, admitting he enjoys cuckold experience. Strangely he can't find NAME_2, but finds another tape with similar content, but now much more hardcore. NAME_2 whines for violence and NAME_1 is somewhat annoyed about her whore behavior. In result when he watches NAME_2 being tortured he feels arousal, he masturbates and feels pleasure and satisfaction when he cums. Eventually he receives a tape where he watches NAME_2 being mutilated to near death and admits it was best orgasm in his life. Next night he finds himself kidnapped and appears in the room where NAME_2's tortures were filmed. He sees her head applied into guillotine and (to his satisfaction and erection in his pants) she begs him not to save her, but to do her as he pleases. It was all her plan from very beginning to direct NAME_1 into enjoying the tapes to join her in that grotesque pervert act.
