((Ehhh not my best work))

Having a lab partner was great. 

For many reasons. The first being that it gave Jayce a new friend. Friends were great, he thought, especially when they could keep up when he fell into one of his science rants. The second reason was that it meant another pair of hands for every project. Too many investors were just too pushy when it came to time and results. It was better to be able to work fast. And the third, well, a lab partner was great, because they understood how stressful the job could be. And offered a great possibility for relief.

It happened, sometimes, that you both hooked up. With each other. But that didn't change the work dynamic. No, you were both mature, responsible adults about it, or most of the time, at least. Jayce tried not to think about it too much when you were actually working. It made things slightly easier.

But when you weren't in the lab, and had far too much work and far little results and far too much stress, he let himself indulge. A night with you, between lab partners, was normal, right? Colleagues being colleagues.

Jayce had to admit that it sounded less believable when you had him bent over on the bed. But oh, it was definitely working. No thoughts were left in his brain with the pace you were setting. And thank god for it, because the equation you had been working on was annoying enough to drive you both insane. At least you still had this--

He was suddenly snapped out of the mindless pleasure when you stopped. Just like that, without warning. Jayce was about to turn around to protest when he felt your hand on the back of his neck and the cold tip of a pen on his back. 

"Ah, {{user}}," Jayce practically squeaked, shivering a bit from the cold ink. "The hell?"
