Kyran heard the knock on the door over the hum of the music. The noise was muffled by the layers of gauze and the lid of the wooden box above him, but the opossum had strong enough ears to make it out. With the wrappings covering his eyes in the pitch-blackness, his hearing was as sharp and alert as ever. His entombment had only recently been completed and the party had hardly started, so the chatter hadn’t yet threatened to drown out the smaller sounds. He inhaled deeply, trying to steady his heart’s erratic rhythm. His nose was greeted by the smell of sawdust.

“Where’s your mate?”

It was the voice of one of his friends, likely speaking to Seth, Kyran’s longtime boyfriend.

“He got wrapped up in an important project, so you won’t see him tonight,” the otter quipped in response.

“That’s rough. I can’t believe he’s going to miss the party. These decorations are great! Your costume is really cool too.”

They had opted for an ancient Egyptian themed Halloween party, and had gone all out on the decor. Lilting pipes, the rattle of sistrum, and a subtle scent of cinnamon and myrrh provided ambience to their home, which had been thoroughly transformed. Hieroglyphics etched into faux-sandstone covered their walls while styrofoam and cardboard monuments littered the room, all spray-painted with a glinting, golden sheen. Snacks were arrayed on gleaming platters and drinks were served in ornate ewers. Nestled in the center of the living room, amongst fake, giant clay pots, was the most impressive ornament: a life-size sarcophagus made of plywood, but painstakingly carved and painted to look authentic. 

It had taken them all day to get the house prepared for the party. A party that the marsupial was conspicuously absent from. He listened to his partner greet their guests. Kyran envisioned the way his lover looked in his outfit for the evening. He knew that the sexy sea otter was shirtless. Seth’s smooth pelt showed off his sinewy torso. He wore an ornate costume-jewelry collar of overlapping gold plates and lapis lazuli beads along with a matching headdress. Bands of aurum ringed his wrists and biceps. Layers of linen skirts hung low enough on his waist to reveal the the taut V of his upper-pelvis and wooden sandals were tied to footpaws. With a scepter held sensually in his paw, he looked very much the part of an ancient pharaoh presiding over his kingdom.

The costume lent him an aura of authority that made him appear much taller than he actually was earlier as the opossum had been mummified and laid to rest. Kyran remembered how attractive he looked in the regal attire and how he had asked the other male to leave it on while Seth roughly fucked him right after he had first tried it on. The opossum’s nerves calmed as he reveled in the arousing memory.

He felt himself starting to get hard, but his cock didn’t have much space to expand. A metal cage tightly encased his swelling sheath. His shaft fought a brief, fruitless battle against the steel bars before his erection was thoroughly suppressed.

Kyran could scarcely wriggle due to the tight bindings that covered his entire form head to toe. It was a unique and almost panic-inducing feeling of helplessness, laying in the oppressive darkness while immobilized. He could hear his friends all having a good time, occasionally even felt weight of someone accidentally kicking or bumping his coffin as they passed by. They had no idea that inside the prop funerary box was the submissive opossum, securely tied up by his mate.

“Let me show you my favorite bit,” Seth offered excitedly, his voice was closer to the sarcophagus. Kyran could picture him on the other side of the impenetrable gloom.

“Dude! Awesome! Did you make this?”

“With Kyran’s help of course. Actually, if I’m being honest, he did most of the work. It looks good, but that’s not the best part. Check this out! He wired it up to be even better.”

Kyran’s chest struggled to expand with his arms crossed over it with and bound tightly with bandage wrappings. The binding of his naked form was erotically slow. The otter had him assume a proper pose, then started at his footpaws, wrapping layer after layer of gauze around his legs. He gradually moved higher on his boyfriend’s body, concealing his entire figure. The opossum recalled how Seth’s erection prominently tented the skirts of his costume as he made sure his partner could barely move an inch. Finally his head and eyes had been covered and he had been carefully lowered into his tomb. The last scent the marsupial inhaled before the strong smell of freshly worked wood inhibited that sense was the heady arousal of his lover as he sealed him into his temporary crypt.

“See these four hieroglyphics? They’re actually buttons that make the prop do stuff. Go on, try one out!” Seth goaded their friends. His confident voice brought the hidden anthro back to the present.

It was nerve-wracking, not knowing what button would be pressed. How many times. How often. Kyran’s heart fluttered again as he tensed up. He held his breath.

He was hooked up to an e-stim box with four channels. The wires had been attached before they mummified him and ran under his bindings and to separate locations on his helpless form. The device was programmed to stimulate the assigned body part for each button. Each time a button was pressed both the power level and the duration of every channel increased, guaranteeing a stronger reaction as the evening wore on. The tied-up opossum was hyper-aware of his body, especially of: the wires attached to his nipple piercings, the steel chastity cage fastened soundly around his sheath, the electrodes on his fuzzy sac, and the thick vibrating plug in ass.

It was his testicles that received the first shock. Even being prepared for the pleasure mixed with pain didn’t keep Kyran from being surprised. The sharp stab of electricity to his most sensitive bits was followed by a lingering tingle. He yelped in surprise, but the ball-gag in his muzzle muffled the noise into a throaty grunt that easily carried outside the coffin.

“Wicked!” His friend said, obviously pleased with the prop. “It sounds like there’s really a mummy in there. What does this one do?”

Kyran heard the click of a button the split second before he felt the sensation. Powerful vibrations emanated the plug lodged firmly in his cleft. The pattern came in intense waves. The toy was pressed firmly against his prostate, and each buzz caused him to squirm and wriggle violently in his cramped chamber. His bound form shuddered and smashed against the inside of the sarcophagus with each pulse along his pleasure center, causing the entire coffin to knock about. He moaned loudly as he writhed. His sheath started to swell, but the erection was stifled by the metal cage locked tightly around it, and he felt a damp patch spread on the cloth in front of his cage as he liberally leaked pre.

To anyone outside, it must truly seem like an ancient mummy was trying to rise from his dead and take vengeance on those who have disturbed it’s eternal slumber.

The trembling of the plug ceased as abruptly as it began, leaving its victim horny and unfulfilled.

“Kyran worked hard on that, so make sure it gets plenty of use. I’m sure he wants everyone to play with it as much as possible,” Seth said. The opossum could hear the smirk in his lover’s tone.

Without warning, one of the anthros outside the sarcophagus must’ve tried another switch. Kyran bit hard into the silicone gag as he grunted and groaned. It started as a light hum scintillating across his chest, but quickly accelerated into a stabbing pain as invisible lightning first caressed then attacked his nipples. His fur bristled while electricity was conducted through his barbell piercings and into his sensitive nubs. The tightness arced across his torso. He snarled, but the pained sound was muffled by his gag. The torture was agonizing and erotic, and it was only the unyielding bars of his cage that kept him from getting fully erect.

His member fought a losing battle against the cold metal. Though he couldn’t see the flow of pre leaking from his captive length, he felt his pubic fur get matted with it. He uttered a needy whine, too soft to be heard outside the sarcophagus.

Kyran’s breathing was growing ragged with nervousness. There was only one button that had yet to be pressed, and the marsupial knew his friends well. There was no way they would be able to resist pressing the final button soon, and at least a couple dozen more times before the night was through. He was also well aware of how the voltage would ramp up with each activation until it crested at the upper end of what Seth knew he could withstand. The power was already harsh and the opossum knew where the next shock would come.

He almost whimpered in anticipation.

The restrained anthro’s yowl of anguish was garbled by the gag locking his jaw in place as power danced across the steel contours of his chastity cage and into his sheath. He spasmed with the intensity of the shock. If it weren’t for his tight bindings, he would have broken free of the prop coffin due to the burst of lighting to his groin. The sensation brought with it a flood of endorphins and the opossum felt himself spray a jet of precum, soaking his wrappings.

“How did you guys make this?” Their friend queried, clearly impressed.

“I’ll let Kyran tell you next time you see him, just enjoy it for tonight. And make sure you encourage everyone to try it out! Don’t want my mate to be disappointed.”

Over the next couple of hours the partygoers seemed to enjoy the sarcophagus and provoking the mummy within. His nipples, tailhole, sheath, and balls were continually abused. Sometimes there were only seconds between jolts. Other times there were minutes. Everytime the marsupial grew close to drifting off due to boredom or inactivity, another anonymous fur was curious about the hieroglyphic buttons on his tomb and gave one or more a press. Throughout the ordeal, his arousal never abated.

The inescapable bondage, the wonderful pain, and the pressure against his prostate from the vibrating plug kept bringing him closer and closer to orgasm, but the cage smothering his maleness prevented that from occurring. Kyran mewled impotently as his torture continued endlessly with no way for him to gauge the passage of time.

Eventually, once the hidden anthro was dazed from hours of overstimulation, he distantly made out the sounds of the party winding down. His struggling had grown weak and his voice hoarse from groaning with the excruciating pleasure. His unfulfilled arousal had not ceased trying to achieve climax as the toy stuffed in his ass trembled with wild abandon, but his hardness was unerringly squelched by its confines.

“Everyone’s gone now. Ready to get out?” Seth inquired, lightly rapping his scepter on the coffin lid.

His boyfriend thumped his body against the inside of the casket a couple of times in response, unsure that he could vocalize a response.

There was a prolonged pause.

“Sorry, Kyran. I can’t find the key-” a hefty padlock had been affixed to the sarcophagus to prevent any curious furs from peeking inside. “I knew I should have worn something with pockets,” the sleek otter snickered. “I’ll have to buy some bolt cutters to get you free. Unfortunately, I had a few drinks during the party and I don’t think I should be driving, so you’ll just have to hang out in there until morning.”

The opossum's throat was parched from all of the groaning, and his muscles were stiff. He ached for release in more ways than one, and didn’t know if he could take another several hours of imprisonment. He whined meekly.

“Don’t worry, though. I thought something like this might happen when we were building this, so to make sure you didn’t get bored in there I took the liberty of making some modifications when you weren’t looking. I’ve programmed in a timer. You’ll get to keep feeling the shocks all night. Isn’t that great!? Anyway, I’m going to bed. Have fun!”

Kyran felt static in the air as a button clicked on its own.
