Suspicion

Stephan Gregor made his way up to the fifth floor labs deep in thought. He was happy about the team that was starting to come together. They'd need a few more capable, and trustworthy hands, to really make the kind of progress his boss was asking for, but hiring was going smoothly.

The elevator doors slid open, and Stephan stepped closer to the only active cleanroom that day, Room 7. His pace slowed when he heard what sounded like retching. Was that coming from the change room? He slowed his pace and opened the door carefully.

The scene was not what he expected.

Mark was hunched over, puking his guts out. Stephan thought he could see some blood in the resulting bile. Sana was a few steps away, eyes wide open and fixed emotionless on Mark. Just... observing. Neither of them were wearing any clothes.

"What's happening here?" Stephan spoke firmly, with equal parts anger and worry.

"I assume some kind of overdose," said Sana casually.

"Assume?"

"Well, I did sneak him a few extra doses. Wanted to know what the effects would be."

This didn't calm Stephan down in the slightest.

"Do you mind telling me what you gave him?" Anger rising in his voice.

"Uh... right. We made a nootropic. Brain boosting ****. A working one. Like, a real actual useful one! And with almost no side effects. Well, I did. Mark helped. As you can see, he's still helping. " Sana grinned sheepishly, but all it did was creep Stephan out. "We've been on it all weekend, on and off. This is the first time I tried upping the dose, but well, figured it'd be safer for me if I wasn't the guinea pig. Helped that he thought he was taking a regular instead of a quintuple dose."

"Why are you just standing there, help him!"

Sana looked at Mark, who was still gagging, his face a bright red.

"I'm not sure what's wrong," she mentioned quietly with a touch of annoyance. "Neither of us had any withdrawal symptoms thus far. I've felt zero nausea myself, and after seeing him do fine fifteen minutes ago, I boosted myself up to a triple dose. The dopamine agonist shouldn't be causing it, so it's got to be part of the nootropic effect." Her hand reached down to her crotch and started idly rubbing it. "Mmm. Physical exertion shouldn't affect this either, the **** was absorbed into the bloodstream a while ago, and doesn't metabolize differently if it goes fast."

Stephan stared at her as if she hadn't explained anything. She realized some context was missing.

"Oh! Right. We fucked five minutes ago." Sana spread her pussy lips and a stream of white goo starting leaking down her thighs. She picked some up on her finger and brought it up to her face, sniffing it before flicking it aside. "It was a lot of fun! And Mark didn't mention my tits at all, for once." Her hand drifted back to her pussy and began rubbing in harder in earnest.

Stephan stared at Sana. She'd always been a bit carefree, but she was acting like a psychopath right now. Mark was now dry heaving, gasping for breath. Stephan quietly reached to his phone, entering one of several emergency codes, before crouching to Mark's side. He started on what little first aid he knew clearing the airway, shifting Mark away from the hard surfaces of the locker benches.

Wait. If Sana and Mark were making the beast with two backs that recently, the hell did Tony see up here? Stephan shook his head. Maybe nothing. Maybe everything. What a mess.

"Do you have the formula for this experiment of yours?" Stephan asked Sana.

"Sure, in my lab book. I can grab it real... unh.. quick."

"Please do, be quick." Sana nodded, and tossed on a fullbody coverall preparing to reenter the cleanroom. Stephan sighed with relief a little inside. That would buy a little time for the cleanup crew to arrive. He expected they'd make it here quickly enough to save Mark, but they would probably have to pump his system clean. Mark's eyes were rolling back in his head and his mouth was beginning to froth, when Sana walked back in minutes later.

Stephan grabbed the lab book impatiently from her, poring over the notes. Incredibly detailed notes, well written, but only that - notes. Nothing that could help Mark without further testing.

"I'm going to hang on to this," he said pointedly at Sana, who had once again stripped naked and decided to sit on a bench. Back to emotionlessly gazing at Mark's ever worsening condition while fingering herself. "And we're going to put a hold on making any more of this stuff. It might very well be useful as you say, but... you said there were no side effects right?"

Sana was gasping and rapidly rubbing her pussy now, closing her eyes. "... almost ... unh ... no ... side effects.. unh..."

Stephan rolled his eyes. "Right. Yet, you're obviously pretty... aroused, and either had no shame to begin with, or have had it suppressed. I sincerely doubt you've been this open with previous coworkers."

Sana's eyes opened in alarm. "Shit. You're ... unh .. right. Hell of a blind spot. Wow... like I knew... mmm... as a dopamine agonist there would be some loss of inhibition, but I didn't even notice it."

"So as I said, we're going to halt this ****. Depending on what happens, you're in a huge amount of trouble. And no matter what happens, we're going to have a serious talk about medical ethics. And boundaries. And consent. And safety. And, needless to say, conditions for your continued employment here at LabSy-"

"Hold on a sec." She sped up her rubbing to a rough jerk, throwing her head back as she growled her way to an orgasm. Her slick pussy spasmed a few times as she brought her hand away. It joined her other hand on the bench behind her to support herself as she twitched. A moment or two later she brought her head up, sweaty and satisfied. Mark was twitching on the ground her entirely different reasons.

And just then the cleanup crew arrived.
