Jess, with the Tan and Ass

“Say Jess, why don’t we take a crack at the methyl benzoate and diethyl ether?” you ask. Maybe not the smoothest line, but it’s the best you could come up with in a flash after spending a good few seconds trying to decide between the girls.

“I like it,” Jess says, picking up a syringe. “Umm.. wait, what do I do?”

“Here,” you say, shifting up close behind her. You gently clasp her hand in yours, and feeling her look back at you a little nervously, you slowly demonstrate how to withdraw the proper amount of solution. I mean, this is stuff that a ten year old could do… you think, but you’re not complaining, because you’re up close and holding hands with a real hot girl, and she seems to like the way that you show her the ropes.

Together, you measure out and form the mixture, your firm hands guiding her delicate ones, and it isn’t long before you’re done.

“So… what’s next?” Jess asks, biting her lip slightly. Damn, she looks hot when she does that.

“We’re going to need the flask with a spin vane for the magnesium,” you say, pointing to a piece of glassware to the side. “We’ll need it for refluxing later.”

“I see,” Jess says, shifting over to grab it. As she does, her ass presses against your crotch, and you keenly feel her sandwiched between you and the table. Her breath hitches a touch, and you up the slight pressure. When she gets the vial and doesn’t move back out of place, instead starting to measure out some magnesium, joyous fireworks go off in your head.

“Just like that, that’s great,” you tell her, ever-so-slightly grinding against her; she dumbly nods, trying to focus on weighing out the proper quantity of magnesium, either oblivious to the stiffening cock pressed against her, or feigning ignorance…

Chris, who’s helping Sam through the other mixtures, starts a little when his phone goes off.

"Oh shit, we should be done refluxing for our lab!” he says.

“Ah shit,” you say. Does that mean you have to head back to your lab bench? You’re really liking the feeling of your cock against Jess’ ass, and you get an idea. “Well, since these pairings seem to be working pretty well, do you want to go with Chris, Sam, and take care of our lab? I’ll stay and work with Jess until lab’s over today.”

“I’m game,” Sam says, and Chris nods enthusiastically, the two of them heading over to your bench.

“You’re a sneaky one. I like that,” Jess whispers, looking back at you again. “But unfortunately, I’m going to have to move to work with what Sam and Chris left here.”

She shifts away to the other end of the bench, to your disappointment. The two of you work well together for the remainder of the lab—although it wasn’t quite like the perfectly in sync efficiency that you had with Chris, Jess is a quick learner, and she listens carefully to what you have to say.

By the end of the lab, you’re mostly done with the synthesis, and you see that Chris and Sam are in a similar place.

“See you next week,” you say, and Jess smiles back, rushing over to Sam and whispering something in her ear. The girls giggle and head out together.

“I think we’ve got something good going on here,” Chris says, clapping you on the back.

“Oh yeah, can’t argue with that,” you say, and Chris laughs.

“I’ll catch you next week,” he says.
