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 at the moment when stranger cuts away NAME_2's limbs. On the next tape NAME_2 has her limbs sewed back with seams perfectly visible, but during the rape stranger slits her throat and fucks her bleeding body, at the climax he cuts her head off and cums into it. Further tapes are even more twisted necrophilia tapes with NAME_2's corpse misses head or has it sewed back but sliced away at the end of tape, on one of tapes she has a horse head sewed to her corpse instead of her own head. Other tapes invest further into NAME_1 enjoyment macabre stuff happening to his ex fiancee. He searches for next tape eagerly, he makes masturbating to those tapes some kind of pervert ritual.
One night he finds himself kidnapped and appears in the room where NAME_2's tortures were filmed. He surprised to see her alive and intact but instead of asking him to save her she wonders if he liked the tapes. She drops her white dress down and NAME_1 sees her dressed into tight see-through dark latex outfit that could suit a vampire domina mistress. She laughs about his confusion, opens that the girl that looked like NAME_2 on tapes is a skilled actress that indeed was beheaded during sex. She explains that it was her plan from very beginning, she directed and manipulated NAME_1 into enjoying the tapes to make this night possible. Now she wants him to join her and do her like he saw on the tapes.
