The heavy cellar door squealed loudly as it was pulled open, its rusty hinges shrieking in protest. The slender fox stared down at the stairs leading into darkness below, the last vestiges of sunset casting a weak glow on the first few steps. 
“Are you sure he’s already transformed?” He asked the taller more robustly built canine beside him, ears twitching nervously. The dog glanced at the vulpine, smoking a cigarette as they both stood outside of the cellar behind his house. 
“Positive. I’ve already drugged him and got him bound up. He’s all ready to go for you.” the burly boxer said, flicking ash away from his cig. 
“And are you really sure you want to have this done? I mean, I do it all the time at the clinic but...I’ve never neutered a werewolf before...” the vulpine scratched the back of his neck sheepishly as he spoke. It was true, as a vet he had removed the testicles of many a male feral canine, but this was different. Even though the male inside the cellar was in a bestial form now, when he awoke and changed back into his normal form, he would be missing a few important assets. 
“He’s becoming too much of a handful on his moon-nights. Two ladies on this block are already pregnant with his wild-oats and several of my male neighbors have had to have their asses sewn back together after he’s knotted them. Not to mention he’s killed several neighborhood pets. He’s starting to get willful as an anthro too, and he needs to be reminded of who owns him.” said the boxer, looking up at the darkening sky. Night was fast approaching, with only the western sky showing any hint of fiery sunlight. Stars were encroaching fast from the eastern horizon. 
The fox nodded quietly. It wasn’t any of his business how the boxer and his mate conducted their relationship, but this was a once in a lifetime opportunity. He wet his lips, nervousness starting to turn to excitement. He was going to get to cut off a werewolf’s balls! 
“Well, I guess I better get started.” said Tobias, the fox. He picked up the leather case beside his feet and started to head down the stairs. 
“Bring them to me when you’re done.” The boxer said, tossing away the butt of his spent cigarette. The fox nodded, listening to the squeal of the rusty hinges as the boxer closed and locked the cellar door behind him. It got too dark to see for a long moment, but as the fox’s eyes adjusted he could see light at the bottom of the stairs faintly. He carefully felt his way down, until he reached the cold cement floor of the cellar. It was lit by a single bulb, and contained only the large furry form of the werewolf he was there to unman. The huge beast was slumped against the wall, curled up around himself. Tobias was intimidated at first, staring at the huge lupine creature in front of him. The werewolf was at least three times the fox’s size, with thick shaggy black fur all over him. His paws were big enough to cover Tobias’s entire head in their padded palms. Tobias swallowed, his heart pounding as he wondered just how big this beast’s wolfhood was going to be! 
Excitement bested fear as the fox moved forward, watching the huge drugged monster sleep on the concrete floor. The boxer had told him that the drug would make him sleep as long as he was alone, but when the fox was there and had him awake, it would make the werewolf pliable and obedient. He knelt down beside the big wolf and set down the leather case that the boxer had given him. “God, he’s so huge!” Tobias thought to himself, seeing that even curled up in a ball the massive lupine beast was bigger than Tobias was tall. 
“Hey...hey there, big guy...time to wake up...” Tobias whispered, reaching out a trembling paw and touching the top of the werewolf’s head. He rumbled sleepily, making Tobias shake even more as he scritched the top of the werewolf’s skull between his ears. One round amber-colored eye slid lazily open, fixing a beady black pupil on the nervous vulpine. Tobias bit his lip, fighting the urge to run screaming out of the cellar when that eye locked onto him. He thought for sure that the huge beast was going to pounce on him and rape his legs out of socket or worse. But instead the big creature just yawned cavernously, slobber-sticky red tongue curling out of his mouth. He stretched out, kicking out his long muscular legs, rumbling in his barrel-chest the whole time. He laid there, though, like an enormous house dog expecting belly rubs. Tobias however wasn’t interested in rubbing his belly. His eyes were locked on the fat furry sheath that dangled between those stretching legs, and the pair of massive musky wolfnuts that sagged behind it, pooled against those powerful beast thighs like a pair of tennis balls in a velvet bag. The werewolf rolled onto his back completely, tongue lolling out of the side of his mouth. He was still very drugged, obviously, but Tobias didn’t care. His fear was fast subsiding, chased away by the rushing arousal that was heating his blood like a wildfire from his groin. 
Tobias leaned forward, grunting as he felt his erection scrape against the stiff fabric of his scrub pants. He buried his nose alongside that fat wolf-sheath between the drugged moon-lupine’s thighs and breathed in deep. A rush of pure pheromone-laden musk poured into his nostrils, nearly scrambling his brain with the scent of male beast. His paws curled around that lolling sheath, squeezing it and feeling the hot dormant masculine flesh within. The werewolf snorted, feet kicking lightly as his huge head flopped toward his chest, looking down the length of his body. Tobias froze, wondering if the drugs were wearing off for a tense instant, until he saw the goofy tongue-lolling expression on the werewolf’s muzzle. He was still deep under the influence, his mixture of feral lupine and anthro features showing nothing but half-stupefied lust as the fox fondled his sheath. Tobias gasped as a searing heat pressed against his cheek, and he looked to see the tip of the werewolf’s cock poking out of his sheath now, the sheath itself thickening up under his fingers. The werewolf groaned in that contented canine fashion and let his head flop back onto the concrete floor, legs spreading wider. Apparently he was eager for the fox’s attention! 
Tobias chewed his lip, staring at the bulbous purple cockhead that had slipped out of the werewolf’s sheath. The scent that wafted off of it was nearly intoxicating, purely male and pure sex. He had been expecting a large red canine cock like the dogs he had seen at the vet’s office, but the werewolf seemed to have kept his glans and shaft.  Tobias struggled with his willpower, knowing that this werewolf was the boxer’s boyfriend, but he couldn’t resist his urges. Without further hesitation, he leaned down and started to lick and suckle at that fat knob, causing the werewolf’s toes to spread and clench as his cock hardened further, straight into the fox’s mouth. Tobias struggled to take it all, the huge lupine’s member bigger than any other cock he’d sucked. He gagged as that wide head, stretching his jaw far wider than it was meant to comfortably, probed for his tonsils, seeking to sheath itself in the tight confines of his throat. Almost in retaliation, Tobias grabbed the werewolf’s massive balls and squeezed them, making him grunt and jolt suddenly, but that huge dick only got harder, pulsating against Tobias’s tongue as the salty tang of precum started to burn across his tongue. His jaw was stretched wide just trying to accommodate the head of the huge werewolf’s shaft, too big to fit properly inside the fox’s mouth. Tobias grunted, swallowing around that huge knob as his eyes widened in surprise. He squeezed down on the werewolf’s nuts once more, and again precum flooded his mouth and the big beast writhed beneath him, toes kicking and rumbling deeply. It seemed that he could feel no pain, only pleasure. It must have been a side effect of the boxer’s drug. That would make things much easier. 
Finally, after a few minutes, Tobias came up for air, gasping as he swallowed the thick mouthful of precum the werewolf had leaked and spurted into his mouth during his blowjob. The fox stared at the hard cock on the big beast’s belly. It was red and engorged, throbbing and twitching with his heartbeat and the head of it was deep purple and capped off his shaft like a mushroom. It was so thick that Tobias hadn’t been able to get any of the shaft itself in his mouth, he had just licked and sucked on that huge head, teasing and licking it as he pumped on the shaft with his paws. The big beast seemed very riled up now, squirming as the pleasure had left his huge dick. His once-sagging nuts were tighter now, but still hanging low under his shaft but obviously ready to give up their load. Tobias whimpered, his own cock twitching inside his scrubs. He had leaked a dark stain down the front of his crotch, his own precum making a sticky smear across the fabric. He desperately wanted to see the werewolf cum, but he worried that the boxer wanted his balls to be full. As much as he wanted to see the big beast’s orgasm, he decided that now was the time to cut off his balls. 
Tobias picked up the leather case that the boxer had given him earlier and opened it. He gasped lightly at the gleaming silver blades inside it, custom made scalpels plated with platinum silver. He could tell they were exquisitely sharp, just watching the harsh light from the single bulb above play along their edge. He knew that if he castrated the big beast under him with those blades, his balls would not grow back. The little fox moved around, from beside the werewolf to between his legs. The werewolf spread them wider for him, allowing him to kneel right between his legs where his sagging nuts dangled freely, as though expecting further pleasure. He whurfled slightly as the fox took hold of his nuts, stretching and tugging down on them to get some slack in his ballsack. He massaged them until he could clearly see the werewolf’s cords against the thin skin of his scrotum. Tobias paused, swallowing as he watched those cords pulse against the skin with life and virility, the cables connecting the werewolf to all his masculine energy. And here he was, small, horny Tobias about to castrate this huge beast, about to separate him from all of his maleness. The thought made the little fox shiver and nearly blow his load in his pants. His trembling fingers selected a blade from the kit, and he leaned in close as he went to work. He started by slowly slicing along the base of the werewolf’s scrotum, delicately peeling away his pouch from his groin with the razor edged blade. It was so sharp the edge of the flesh seemed to just leap away from the blade, peeling apart so smoothly the fox could barely feel it. The werewolf, however, seemed to feel it. His legs kicked and jerked and his cock bobbed and spat precum across his belly in globs. Both he and Tobias shivered and moaned as the little fox took hold of the bottom of that furry scrotum and tugged lightly, and it slid off of the werewolf’s testicles with a wet slurp, like a glove from a hand. 
There they were. Like fat ripe fruit that werewolf’s naked testicles dangled freely and unhindered from his groin by their cords. Veins chased across their surfaces, the cords and vessels pulsing with life and fluids. Tobias swallowed, staring at the werewolf’s still warm scrotum in his paw, vaguely imagining what the werewolf would think if he knew his precious balls were hanging out in the open air. As it was, he seemed to be highly enjoying it, panting rapidly and shivering with obvious delight. The boxer had acquired one hell of a drug! 
Tobias reached out, taking hold of one of those massive testicles in his trembling fingers. It was warm and slick with fluid, throbbing against his fingers. The werewolf squirmed, panting loudly. Tobias grabbed the blade again and brought it up close to the cord, seeing the werewolf’s natural healing already closing the wound where his scrotum had been and leaving the cords of his balls exposed. This was it. The werewolf was about to lose his balls forever. 
Tobias touched the blade to the cord and it split. He blinked as pure white sperm welled up from the cut, dribbling down across his fingers. He cut a little more and more sperm poured out, the werewolf starting to bark and huff. His cock looked ready to explode, his entire body twitching. Tobias sliced again, nearly halfway through the cord and semen poured out steadily now, leaking across his fingers and dripping wetly onto the concrete below. The werewolf’s balls were so primed and ready that their load was pouring out of them, welling out like water from the ground. Tobias groaned, he’d never seen so virile a male. He pushed the blade deeper, shivering as more cum poured out, and the werewolf thrust his crotch upward suddenly. Tobias’s blade jerked downward accidentally, and the razor edge split the back of the werewolf’s left testicle wide open. He gasped, blinking as hot cum gushed out in a stream, splattering across his neck and chest. The hot scent of it was heady and raw, and Tobias panted as he saw he had split the werewolf’s epididymis cleanly in half along his nut. The werewolf bucked and barked, his penis twitching and throbbing like he was about to cum. Tobias didn’t want him to lose all that sperm, so he cut faster, severing off the werewolf’s left testicle. He sat it to the side, groaning and panting that he’d just half-castrated the huge beast, as he started to work on his right nut. He cut faster this time, and with the faster cutting the sperm shot out more rapidly, gushing in streamers from his cord as Tobias severed the testicle. The big beast jabbed his cock into the air, apparently about to cum just as his last nut left his body and he groaned, twitching and shaking on the concrete floor. Tobias wondered if he was orgasming, but as he watched the wound where his balls used to be seal over, he knew he had been cut just short of it, his nuts stolen before he could climax completely. He watched the big beast’s body slowly go slack, the tension of near orgasm petering off as his balls cooled on the concrete. Tobias carefully tucked the balls into the werewolf’s severed scrotum for safekeeping, so the furry pouch could catch any cum that continued to leak out of the severed balls. He stood up, ready to depart but as he did he stared at the huge beast he’d just emasculated laying there on the ground. His cock was still very stiff and very engorged the head of it still leaking precum. It was obvious he had yet to feel any orgasm, despite all the pleasure and stimulation he had received. Tobias swallowed, wanting to help him, but there was another desire rising quickly inside him too. 
The fox set down the leather case of silver blades and the werewolf’s stolen balls. He reached into the pocket of his scrubs and pulled out a simple package of normal steel scalpels, ones he had intended to use before the boxer had given him the silver ones. He knelt back down beside the big beast, wondering if he’d orgasm from what he was about to do, but not really sure if he would. But it was just too good a chance to pass up. The werewolf bucked as the fox took hold of his dick once more, amber eyes locked onto the fox and his own cock as Tobias rubbed him slowly. The fox took out his sharpest scalpel and swallowed hard, excitement pounding through him so forcefully he was shocked he hadn’t cum yet. It turned him on all the more now to see the werewolf watching what he was about to do, even with lazy drugged eyes and panting lolling tongue. Tobias swallowed and swiftly slid the scalpel across the underside of the werewolf’s cockhead, splitting his frenulum from side to side in one slick slice. The werewolf’s head snapped back, his hips jolting as pleasure shot down his shaft, the severing nerves firing off under the influence of the drug. Tobias sliced again, and pulled back in the werewolf’s knob with his fingers, spreading the cut open and peeling back on it. He cut again, shallowly and peeled more, widening the cut slowly as he delicately removed the werewolf’s cockhead. With every tiny slice the werewolf shook and shuddered, his hips shaking and thrusting. He was orgasming now for sure, the way his amber eyes were rolled back in his head as the fox shaved off his glans, every cut shocking another orgasm through his system. The fox kept working, slicing, peeling, slicing, peeling more and more until that big fat knob started to peel off on its own, and the scalpel wasn’t needed. Tobias just kept pulling slowly until that massive fist of flesh at the tip of the werewolf’s dick gradually came off in his paw, leaving a flat edged blunt scar at the end of his shaft where it used to be. This wound would heal, Tobias knew, but that was what he intended. The werewolf seemed to have blacked out after orgasming so hard losing his cockhead. Tobias stared at the massive cockhead in his paws, the huge mushroom of flesh filling his palm like a handfruit. He spent the next ten minutes slowly nibbling at that huge head, devouring the musky male flesh steadily with his small teeth, the purely male meat exciting his tastebuds in a way no other food had. He’d never done that before, but he knew as he carried his pilfered prize upstairs to give to the boxers, that he would definitely be doing it again someday.
