She knows exactly what happened

May only took one look at Steve's inhuman cocktail and Chris' foot-long tongue before her face dropped. "Ah. I see."

Steve looked at her with an expression that read somewhere between incredulity and relief. "You're not... grossed out by this?"

"Nae, laddie. I would be if I hadn't seen it all before." She moved closer with a hesitancy, like approaching a wild animal. "And I ain't gonna say anything about it, either. But you're gonna need a way t' get out of here without anyone seein' ye both. I've got me car out the back, so just tell me where ye need t' go-"

"Hold on," Steve interrupted, pulling himself upright. "Why exactly aren't you freaking out? What did you mean by you'd seen it before?"

May sighed. "I suppose I'll have t' show ye."

Slowly, she unbuttoned her pants, letting them fall to the floor and reveal two hairy, muscular legs that were certainly not human. If anything, they looked more like a cow, with the cloven hooves and tail poking out from behind. The crowning jewel, however was the huge bull's cock that jutted from her crotch, her tenis-ball sack hanging to her knees. Chris' mouth lolled open.

"Ye see, me boyfriend took some pills t' grow his penis, got it from some sketchy site. Railed me one last time in bed before he became me girlfriend. Started feeling some cramps in my legs, and what d'ye know, I'm a minotaur, just like that. Now I get to plough his fields, if ye know what I mean."

Steve cocked his head. "But Chris never took any of the pills, or at least I don't think he- she did."

Chris was lucid enough to shake his head. "Got like this... big woman... huge dick..." he mumbled.

"Oh, that's not good." May shook her head. "If that was someone who took a pill, that's three people changed without losing any potency. Ye didn't leave any cum lyin' about did ye?"

"Possibly?" Steve blushed. "It was just in our flat, though."

May didn't look convinced, but waved him off anyway. "Does nae matter. We need to get ye out of here fast, before people start seein' ye. Get dressed, ye comin' with me."

In no position to argue, Steve quickly pulled his jeans up, but pause as they rubbed against his tail. Frowning for a minute, he placed his hands on either side and pulled, feeling the fabric rip under his new, strong muscles. The large, fleshy appendage fit well in the hole. Then it came to Chris. He was still out of commission, rolling on the floor with one hand on his belly, unable to move. Gently, Steve pulled his clothes back onto his body and scooped him up in his strong arms. Chris made no move to protest, instead snuggling deeper into his warm, muscular chest. Quickly, the three of them hurried through the carpark and piled into May's beat up old van.

Once inside, May breathed a sigh of relief, giving one last check at Chris, who had been reluctantly extracted from Steve's arms and laid down on the back seat, before driving off. Steve couldn't help but stare out the window with a twinge of fear as they passed by people on the street. Every now and again, his tail would twitch, and he'd give a worried glance to see if anyone had noticed. The eighth time it happened, May laid a placating hand on his thigh. "Lad, you best be calming down a bit. The more ye worry and get all twitchy and nervous, the more people are gonna think something's up."

He took a deep breath. "Yeah, you're right. You're right." He sighed. "It's just so... overwhelming, y'know? I mean, just a few days ago, Chris and I were two normal guys, who liked going to the beach and hanging out as friends. And now, well, look at us! There's not going to be a 'normal' anymore."

"I understand, lad, I do," May replied. She sucked in a breath, her hands tensing as she gripped the steering wheel. "An' I know this is hard t' hear, but I suspect you ain't out of the woods yet."

"Excuse me?"

"Look, I went through the same thing as ye. I did nae become a bull in a single day, an' I'm guessing it took a while for ye lassie to be fully... well, a lassie, aye?"

Steve eyed her suspiciously. "Yes?"

"What I'm sayin' is whatever is causing this-" she gestured to all of him, "-takes time to pick a form it likes. An' with you, it ain't gonna stop until ye fully transformed. Ye might want to stay indoors until that happens, if I'm right about ye."

"Right about what?"

"I've been takin' a stab in the dark about what you'll be. Best guess - incubus. With that tail an' all."

"Shit," Steve breathed, resting his head back against the chair. His tail curled around, nestling into his lap as the realisation sunk in. "Shit."

"Aye, lad," May nodded gravely. "I hope I'm wrong, but I rarely am. Which leads me to the final problem."

"God, how much worse can it get?"

"That's just it, I think it can get a lot worse." She pulled up to the apartment complex, leaving the car running as she turned to look Steve in the eye. "I think that every time whatever this plague is claims another victim, it gets stronger. Think about it. Taker o' the pills is transformed a little. The next person they fuck is transformed even more. You're the third one on the chain, an' yet ye have the most drastic changes yet. Lad, if this goes on, we could have something real bad on our hands, real quick. As long as ye don't fuck anyone else, apart from those transformed already, we'll be fine. But ye have to promise me. Swear it."

Steve numbly crossed over his heart. "I... I swear."

"Good, now get ye lass and get inside, before someone sees the two o' you." She clicked her fingers in front of his face. "Quickly!"

That snapped him out of his stupor. Hurriedly, he tucked his his tail underneath his shirt, and rushed around to help Chris. Luckily, Chris didn't seem to have heard the dismal prophecy, or if he did, hadn't understood it enough to be scared. He allowed himself to be scooped up into Steve's arms, his eyelids drooping as his body began to shut down completely, all energy focused on absorbing every nutrient from his protein-rich meal. Unfortunately for Steve, this meant that Chris had become a human equivalent of a ragdoll. The rotund femboy kept rolling about in his arms as he sped across the parking lot, giving a last thankful wave to May as he ducked inside. Giving up on carrying his partner gracefully, he slung Chris' prone form over his shoulder.

Skirting through the halls, Steve was careful to dodge the busiest halls, quickly slipping up the stairs to his room. It wasn't until he slipped inside, though, that he realised his tail had fallen out. It will be fine, he thought. No-one saw us anyway.

Too tired to deal with much else, Steve gently laid Chris down on the sofa, before moving to the bedroom and collapsing. He was quick to remove his clothing, suddenly finding it too restricting, and let his tail lash free. He just laid there for a while, staring up at the ceiling, finally letting everything May had told him sink in. It was hard to digest, the fact that his body might be so irreversibly changed that he couldn't hide it, or that whatever this thing was, it would keep spreading and infecting people like the plague, yet only grow stronger as it did so. When he transformed fully, would he be as sex-crazed as Chris? Or worse? The idea chilled him to the bone.

But slowly, the thoughts of the eventual sex apocalypse made way for the haze of tiredness. His eyes drifted shut, and he fell asleep.
