Chemistry lab

"Okay," Dana says once you reach the lab, "I need your help with this one."

"Um, why?" You ask.

"I heard that dork Tammy accidentally made a gas that melts people's clothes off," Dana said. "But chemistry isn't my thing. I need you to make it for me."

"I don't know how to do that," you say.

Dana reaches inside the teacher's desk and pulls out a notebook with TAMMY written across it. "That stuck-up professor took her notes after she nearly made the whole class naked. C'mon, tutor! Work your magic!"

You open the notebook and look through the formulas. One of them is labelled as, "Clothing Gas. Don't recreate." You ignore this warning and start making the chemical. The ingredients are left in the cabinets, which are all unlocked.

Halfway through the process, you take a look at Dana to see what she is doing. Her fingers are playing with her pussy while her other hand massages her breasts.

"Don't you dare tell anyone," she says, "but seeing a hot nerd is turning me on."

You gulp and try to think of a response. "Y-You like watching me do chemistry?"

"I like watching you do chemistry naked," she replies.

You turn back to your work and try to focus on the formula. As you are about to complete it, you feel hands grope you stomach and back. "You need to take a break."

"I'm almost done," you say. You want desperately to accept her offer, but if you do you'll never focus enough to complete the task.

"Hurry!" Dana demands.

The clear liquid begins to excrete a green gas. You rip a piece of the lab coat off the anatomy skeleton and hold it through the gas to test it. The cloth slowly unravels in your fingers.

"It works," you say. "Now we just have to wait ten minutes for full potency."

Dana suddenly grabs you and spins you around, forcing you into a hungry kiss. She throws you back onto the table and straddles you between her legs."

"You better make it twenty," she says before slamming her hips into your crotch.
