“Oh no. No no no….” Luke muttered with increasing concern before turning to look at his date. “I have to go, now.”

He tried to stand only to have Stacy’s slender, tan-skinned fingers grab his forearm to stop him.

“Wait! Was it me? Was I going to fast? I’m sorry.” She stammered, cheeks flushing in embarrassment. She had been coming on a little strong. Maybe it had been the alcohol or maybe it was just that it had been a while but she had been all over Luke within five minutes of meeting up at the club. “I just really like you. We don’t have to do anything you don’t w-“

Luke cut her off. “Its not that.” When she gave him a pleading look he cringed. His inherent people-pleasing nature, not to mention his own libido, was screaming at him to stay and spend the evening with her. The other part of him, though, was the part that was worrying him. Was the part that him have to force his words out through clenched teeth. “I can’t… I have to…”

But it was too late.

The tiny muscle spasms Luke had been trying to hide became too much to ignore. His whole body twitched and shuddered as a low, pained groan forced its way from his lips and drowned out anything else he might have said. Stacy blinked in confusion when she felt the arm she was still holding onto throb and flex beneath her fingers, only to flex again and spread her grip further apart without ever relaxing. Glancing down at his arm, her eyes went wide when she saw well defined muscle that she was absolutely certain hadn’t been there minutes before stretching the skin of his arm. His shirt sleeve was now filled to the brim with a meaty, swollen bicep that made her practically salivate before the unnatural situation reminder he that it hadn’t been there before, that something was wrong.

When she turned to look back up at his face her eyes went wide when she saw his mouth hanging open in a silent exclamation of pain. But it wasn’t the pained look on his face that left her slack-jawed. It was that his teeth were now unnaturally long and sharped to fang-like points. All of them.

A sickening pop echoed through the room, followed by several more that sent shivers of discomfort down her spine as she watched Luke’s face crack and reshape in rough jerks of unnatural movement. One edge of his chin would crack outwards, followed by the opposite upper edge of his jaw, all the while his teeth were growing even longer and sharper while new ones grew in behind them to fill int he additional space his elongating jaw was creating. More of those sounds of snapping joints and bone came from the rest of his body as his back arched upwards, hunching forward slightly and causing his spine to strain against the skin of his back and his shirt over it. The loudest ones came from his legs where, below the knee, it looked like his leg was breaking in half in several places then healing back together backwards in a manner of seconds.

The sound of tearing fabric drew her attention back to the arm she was still holding, where she saw his bicep having swollen even larger to the point it was bursting his sleeve apart. Her hand jerked away as if electrocuted when she felt the thin hair on his tanned arm rapidly growing and thickening until she soon couldn’t see the flesh at all beneath a growing layer of silvery-grey hair. No…

Fur.

With a heavy thud that shook the floor Luke rolled off the bed and fell to all fours, causing Stacy to scramble to her feet and take several steps away in response. His whole body continued to twitch and spasm as if in the midst of a seizure, each quake of flesh and bone bringing more of those sickening pops and creaks as his body continued to reshape itself. His shirt split across his back as his shoulders and chest broadened and thickened far too large for it to contain. His thighs similarly ballooned with layer after layer of newfound, steel-hard muscle until his jeans split at the seams and ripped away. Even his shoes burst open as his feet nearly doubled in size, toes fusing together from 5 toes of differing size into three uniform digits each tipped with a razor sharp claw that cut into her hardwood floors like butter when they clenched. His hands retained their number of digits but each also tipped itself with a matching claw and the whole thing swelled larger until it was slightly disproportionately large even relative to the sheer size he was growing to. And growing he was.

When he slowly rose up to his feet, still in the midst of his change, he was already towering over her even when still hunching over. When she had first met him he had already been tall enough that she had only been eye level with his chin. Not that she had any complaints. She liked tall men. But now Luke, even without standing up all the way was looming head and shoulders over her so that her face was level with his chest. His thick, powerfully muscled chest. Another tearing sound drew her attention down lower and immediately her cheeks turned bright red with a hot blush. She turned her head away to keep herself from staring as other parts of Luke’s already impressive, from what she had glimpsed from its outline earlier, anatomy ballooned larger with the rest of him until the fly of his pants popped open and his underwear tore apart with the rest of his clothes.

When the discomforting sound of warping flesh finally quieted and the only sound filling the room was the deep, growl laced panting of the beast that had once been Luke, Stacy reluctantly turned to look back at him and immediately dropped her mouth open in shock.

He was still hunched over, his spine now seemed bent slightly so his natural stance was such as if he were meant to be equally comfortable on two legs or four. Despite that, the tips of his ears, because they absolutely were grey fur covered triangular canine ears on top of his head, were brushing her ceiling. Her nine-foot-tall ceiling. The rest of him was covered in the same thick, silvery grey fur that lightened in shade around his stomach, chest and…. Lower areas. A plush weave of the same fur flicked occasionally into view from behind him, telling her he definitely had a tail to complete the ensemble. Stacy was a lot of things, but an idiot wasn’t one of them. She knew it was the full moon tonight, she had thought it would make a nice night to spend time outside with someone if she could find the right guy for the evening. So connecting the dots was easy. Apparently, werewolves were real. And Luke was one.

The beast that had been a moderately attractive, if a bit lanky, regular human only minutes before stared down at her with inhuman yellow eyes that seemed to glow in the artificial light of her room. For an instant, Stacy swore she saw a look of sadness on his face. Muzzle? Though she was far from an expert on lupine facial expressions. The beast turned its massive back to her and took a single, heavy step towards the door. Before it could take a second step a familiar, though now feeling far less restraining, pressure gripped at his now fur-covered arm. When the beast that Luke had become turned to look back he saw Stacy grabbing his much larger arm the same way she had earlier.

“Wait.” She whispered, her eyes wide but her expression otherwise unreadable. “Don’t go.”

Luke considered for a moment. Then his muzzle opened, lips and tongue moving awkwardly as he tried to speak. It became immediately apparent his new muzzle was, while more flexible than a regular wolf’s might be, clearly not meant for fluent communication as each word clearly took effort to form and was as much growled out as spoken.

“But… I’m a monster…”

Stacy locked eyes with the ‘monster’, a brave thing to do considering he was now a nearly nine foot tall supernatural killing machine. A strangely tantalizing scent tickled at Luke’s nostrils, his eyes going wide when he recognized it as the scent of fear he expected but also laced with… desire. At the same time, Stacy’s cheeks visibly reddened with embarrassment as she forced herself to speak her mind.

“You’re the single hottest thing I have ever seen in my entire life.”

There was part of her that was still clearly terrified. Luke didn’t need heightened senses to tell that. But there was also another part of her that wasn’t. Either that, or simply too excited to let her fear get to her. Her voice came out in a forceful, commanding tone like a drill sergeant ordering a cadet… or someone giving their trained dog a command.

“Stay.”

It was Luke’s, the man turned bestial monster, turn to blush. No one had ever spoken to him like that, not even in his human form much less in this one. He wasn’t used to much else than screaming when anyone saw him like this. So he was both surprised and embarrassed by how much he liked being talked to like that. Being ORDERED like that despite clearly being able to rip her limb from limb if he wanted. When Luke slowly, reluctantly, turned back to face her Stacy’s mouth split into a wide grin.

“Good boy.”
