We have to sneak back to the lab

Ming Zhao takes a deep breath and looks into my eyes. "Our spare lab coats are still in the lab. That's our only chance of decency. We can get there, grab them, and go home."

"But that's blocks away," I say. "Can't we just take one from a store?"

"I'm not shoplifting!" Ming Zhao says. "We are respectable scientists!"

I sigh. "Yeah, you're right."

"Besides," she says, "you get a free chance to watch my ass as we run. You really want to pass that up?"

"No!" I immediately say.

Ming Zhao giggles and leads me by my hand. "Alright, let's go."

We run down the alleyway, stopping by a few trash cans. Ming Zhao takes the lids to block her breasts and pussy. I look for something to cover with, but all I can find is an empty paper bag. I nervously hold it in front of my junk as we set off.

Ming Zhao takes point as we hop from alley to alley. At the first stop, she instinctively holds her hand in front of me to stop for cars. She quickly realizes her mistake and covers back up with a soft, "Eep!" I can't see her tits, but her hand brushes my chest. I can feel an erection growing against the bag.

The next few alleys pass without incident until we are within sight of the front door. It is midday and employees are leaving for lunch, pouring out of the building by the hundreds.

"Okay," Ming Zhao says. "The lobby has minimal security and employees now. Our best bet is to just go in and use our credentials to get past the doors. I know the girl at the lobby. She can buzz us through."

A strong wind suddenly rips the bag out of my hands, leaving me completely exposed. Ming Zhao hears and turns around to face me, her eyes dropping to my cock. She grows a mischievous smile before rolling her eyes and tossing the lids away, leaving herself open to me and causing a loud crash.

"Why did you do that?" I ask.

"I'm not covering up while you're left embarrassed," she says. "This is my fault, after all. Now, let's go."

"Wait!" I say. "Why don't we just sneak in through the service tunnel? No one will see us!"

"Because getting through the doors will be a pain in the ass," she says. "I'd have to hack through the security on each one. This will be faster."

"We can't just walk naked into the lobby!" I plead.
