Up we go

Tony breezed through setting up his computer, the guide was straightforward but written for an older audience. His generation had never had the kind of trouble with digital devices the way the last few generations seemed to, thankfully.

He took the security pass and walked over to the elevator. Time to test it. He scanned it and pressed the button for floor 5, and was whisked up. He walked out to again see Sana and Mark still in full lab gear, apparently chatting while moving some glassware (though the glass was soundproof, so we only saw their jaws moving under their mouth masks).

The larger figure (Mark?) saw him, and pointed at the window looking at the smaller one. The smaller one (Sana?) looked over too, waved again, and seemed to say something to the larger one. In front of Tony's eyes, they did a quick round of rock-paper scissors. The larger one cast Rock, the smaller unfortunately had picked Scissors. As the larger one fist pumped the air, the smaller one headed over to the airlock door. A minute or two later, a short Asian-looking woman stepped out of the other end turning the corner.

"Hi! You must be Tony," she said, extending a hand. "I'm Sana. Welcome to the team! Sorry for the delay, getting suited up is such a pain."

"Thanks! And sorry, I guess I'm going to learn the pain myself here shortly."

"Right you are. Then again, working on Sundays can be pain enough."

"I could have maybe chosen a better day for the first one, huh," Tony said. "Though I figured with school it'd be easier."

"Yeah, really. At least this way you get to learn from the real pros," Sana said turning a finger to herself. "Okay, hold on to your butt, we're going in." She turned back to airlock door, opening it again. She and Tony stepped into what looked almost like a space station's locker room. It was loud, with air from the ceiling rushing down to the floor, with round holes sucking in much of the air.

"This is the change room, which is not strictly the airlock. Keeping them separate is very important, you don't want anything not already gowned entering the airlock." Sana said loudly enough to be heard over the rush. "Now this, this is the proper airlock door," she said pointing to what looked like a submarine hatch. "The air pressure is here is lower so that positive pressure from inside the lab will keep any nasty particulates out. This room is sort of like a giant vacuum."

Tony nodded. The cleanrooms he had been in has used the air pressure trick for their airlocks too, though the change rooms he had used had been across a hall, usually.

"Only one door of the airlock can be open at any time. The doors naturally close after a moment or two. Plus, there are tools to override opening and closing the doors both inside and outside the cleanroom. That said, if the outer door was being blocked open, and you were inside the cleanroom, you would be trapped in there. Scary, huh?" Sana said, smiling nonchalantly.

"Erm, yeah."

"Ha, I'm just kidding you. The overrides close the door with enough **** to crush anything trying to hold them open. We need to get gowned up, and then we'll head inside. Okay, now strip."

Tony blinked for a moment, realizing that Sana had begun to take off her shirt. And then that the shirt was off, and she was only wearing a solid black bra up top.

"W-what?" Tony said. Sana looked up to see him blushing madly, while pulling off her shoes

"Oho, a cleanroom virgin eh? You'll have to get used to this sometimes. We've got a few cleanroom procedures, and lucky for you, today's lab requires a full clean." She pulled down her tights revealing shapely, if short legs, smooth and hairless. "It's just nudity, but if you're opposed to it, you can turn away for this. You can still hear me, which is mainly what counts."

"I've been in cleanrooms before! I thought... in most cleanrooms, the full clean suit is enough." He looked at her half-naked form petrified considering whether to look away or not. She was waiting to remove her underwear, putting the clothes she had taken off so far into a locker.

"Yeah well, today's serum is pretty unstable. You really don't want anything on you getting into it. Or... anything from it getting on you. Hey, are you going to strip or not?"
