It was a quiet night tonight, the only signs of any activity coming from the dim glow of a computer screen, the silences broken only by quiet moans.
Blaze the cat was sitting alone in the dark, watching erotic videos on her computer.
Her fingers rubbed her clitoral hood, occasionally slipping a few fingers inside her vulva, while the others pinched and teased a nipple.
She quietly panted as she watched the actors on screen perform, this wasn't your normal pornography mind you.
In this video, a well endowed mobian male had his female partner bent over and locked into a guillotine, one hand on her ass, the other on the release lever.
The woman was blindfolded with her hands bound behind her back.
As she cried out when she came, the man pulled the lever, the blade severing her head with a meaty thunk. 
He then popped his dick out and moaned loudly as he spurted all over her spasming body.
The sight of it all caused Blaze to cry out as she climaxed, squirting as she orgasmed to her darkest fetish. 
Exhausted, she closed her eyes and fell asleep with a soft purr, not even bothering to pull her pants back up.
Silver was staying with her for the night and had heard her, the door flew open, nearly banging into the wall.
Any intentions of asking if she was okay were immediately wiped from his mind when he saw her reclining in her chair, pants around her ankles, breasts exposed, her cooch still soaked from her earlier activities.
He felt his face grow hot, and it only grew hotter when he saw the kind of porn that was playing back on a loop on her computer screen.
Grinning, he powered down the computer and covered Blaze with a blanket.
Quietly closing the door behind him, he went out into the night and gathered several materials. He had no idea Blaze was into snuff like he was, but now that he did, he decided that he would work hard to surprise her with something they'll both enjoy. Too bad they could only enjoy it once.

The next morning, Blaze woke slowly, feeling very refreshed. She quickly noticed the blanket covering her, and that her pants were still down.
Her cheeks turned a deep red as she quickly deduced that Silver most likely had heard her last night and came in to check on her, which meant he saw, well, pretty much everything.
Casting the blanket aside and pulling her pants up, she quietly walked into the kitchen for some breakfast. Silver was there too, serving a plate of scrambled eggs and sausage. She seated herself at the table, only meekly saying "Thank you" to Silver, her face getting even redder.
They both said nothing to each other as they ate, the silence growing more awkward by the minute. After taking a sip of juice from his glass, Silver cleared his throat and said to her "I didn't know you were into snuff."
Blaze paused just as she was about to take another bite of sausage. So he did see her last night. Silver chuckled as she stared at him. "You're not the only one into the kind of stuff ya know." He confessed, his own face turning a shade of red.
She blinked. That was not what she was expecting, but it was welcomed none the less. "I-I see..." Blaze stammered a little, trying to regain her composure.
Silver gulped and opened his mouth, his face turning brilliantly red as he tried to work up the nerve to ask her what he'd be dying to ask since last night now that he knew what she was into.
"H-hey...I was thinking...th-that m-m-maybe...we could...I-I-I-I mean we can only d-do it once so if you didn't want t-to I'd understand, but since we're b-both into s...s...s-snuff..." Silver stammered.
Blaze's eyes widened, and her heart raced. "S-silver...a-are you asking if I want you to snuff me?" Her voice shook a little, and she started to get aroused.
"O-only if you wanted to of course!" Silver assured her. "And...I'd snuff myself too..." He clarified, again turning red.
Blaze went quiet for several minutes, thinking it over. Finally, she smiled and nodded.
Beaming, Silver stood up and kissed her on the forehead. "Leave everything to me, I'll get everything set up in the guest bedroom." 

Over the next few weeks, Silver was hard at work putting everything together.
Blaze had no idea what he was doing, and despite offering to help numerous times, Silver asked her to let him do all the work himself, he wanted it to be a surprise he said.
Throughout the weeks, the sound of hammers banging, saw blades whirring, and occasionally, Silver cursing whenever he hit his hand with a hammer, Blaze grew more and more anxious. There would be no going back on this, and as crazy as it was, that's what made it exciting. 
To sate her appetite, her and Silver sexed each other up, her favorite moments being when he would tie her hands behind her back and fuck her from behind while they watched various snuff films. 
Each orgasm was intense, but they would pale in comparison to what she'd experience during their final romp.
Finally, construction was complete, and their last day on earth was here at last.

Blaze was sitting on the sofa in the living room, Silver snuck up behind her and wrapped her arms around her. She jumped, but she purred as he held her in his arms.
Slipping a hand down her pants while toying with one of her breasts, he nibble at her neck."Everything's ready Blaze. You sure you wanna do this?" Silver whispered lovingly in her ear.
Her purrs became louder, and with a moan she replied "God, yes. I've been waiting for this for too long Silver...".
Silver gave her one last peck on the cheek. "Take off your clothes lovely..." He purred.
She did as she was told, removing every article of clothing. Pulling out a pair of handcuffs, he restrained her arms behind her back, then led her to the guest bedroom, his cock becoming firmer by the second.
Upon entering the room, what Blaze saw almost made her come then and there.
Silver had constructed a guillotine, but it wasn't just a normal one. The weight on top of the blade was far bigger, and attached to the blade was a rope, guided through some hooks, a noose fastened on the other end.
Now she understood fully what Silver had in mind. She would be beheaded, and Silver would be hanged.
The two lunatic lovers walked over to the guillotine, their hearts beating feircely in their chests, aware that this was the end.
Silver lifted the lunette and guided Blaze's head, locking her in underneath the blade. She shivered as she looked at the mirror across from her, giving her a good view of the two of them. Hands shaking, he put the noose around his neck, his manhood throbbing madly as he eyed the purple feline before him, her beautiful neck waiting for the blade to drop, her pussy now dripping as it yearned to be penetrated.
Silver placed both of his hands on Blaze's hips and slowly teased her entrance with his tip. "A-aaahhh...S-Silver..." Blaze moaned, practically begging him to take her.
Grinning, he pushed himself all the way in, earning a mew of approval from Blaze. He gently traced her fingers up and down her back and sides before leaning down to nibble at her neck and massage her breasts.
As he picked up the pace, Blaze's moans grew louder and louder, to the point she where she was practically screaming. "S-Silver! S-Silver! SILVER!" Her tongue was hanging out of her mouth, her eyes were closed, and she felt she was in heaven as Silver rammed into her, his length filling up her vaginal walls. "Y-yes. yes! That's it big boy, empty those big, beautiful, heavy balls in me!"
Sweat dripped from Silver's face, his cock swelling more and more with each passing minute. Feeling that he was close, he reached up to the release lever ready to drop the blade when they orgasmed. Seeing Silver getting ready to drop the blade, she felt herself on the edge, and shouted "YES! YES! KILL US BOTH YOU SICK FUCK!"
Silver gritted his teeth and pounded harder into her, trying to get them both off before he pulled the lever. The guillotine rocked violently as he did. Finally, Blaze orgasmed, the sudden tightening of her womanhood around Silver causing him climax as well.
With a final yell from both of them, Silver pulled the lever, releasing the blade. A sudden shriek could be heard as the blade descended, the sharp edge easily slicing through bone and tissue, causing Blaze's head to part her body. The heavy weight of the blade tightened the noose around Silver's neck, hoisting him a couple of feet into the air.
"H-HOORK!!!" The only sound Silver could make, his eyes widening as his hands instinctively tried to loosen the noose. His cock popped out of her cunt, throbbing madly as it continued shooting its load. Below him he could see Blaze's now headless corpse spasm in it's final death throes, the tail stiffening as his semen leaked out of her soaked snatch, her legs kicking hard, her clawed feet leaving deep scratches in the floor. He kicked his feet and spun around, some of his come landing on her back. Just when he thought he was spent and waited for death, his cock firmed up again. He bucked his hips, humping the air, and his second orgasm hit him, this time his semen merely dribbling out, a pathetic attempt by his body to desperately impregenate a woman in his last moments. Finally his arms fell to his sides and his eyes rolled up into his head.
The final thought the two lunatic lovers had was wondering if the other enjoyed it as much as they did. Death then claimed the both of them, and they no longer had a care in the world. Silver, who was now turning slowly from the noose, still erect and oozing semen. Blaze, who's body had finally stopped struggling, her sex filled with her lover's come, and her eyes now relaxed, peaceful.
It really is a shame you can only enjoy this once.
