You're working with your coworker Alexa in the lab late one night when a terrible accident happens - she spills a new chemical all over your lap, coating you in this new mystery substance that is supposed to have warming qualities. "I don't know what it's going to do, just take off your pants!" Alexa says panicking, grabbing a pair of latex gloves and some special cleaning stuff to rub all over the afflicted area. You strip while she handles the clean up, rubbing this slick, wet cleaning gel all over your legs and crotch. "Oh no, it's starting to swell!" she cries. She starts cleaning more vigorously and uses both hands to rub up and down the shaft of your cock where the chemical spilled. Hot from the upper body workout, she strips off her lab coat revealing the tiny lingerie she was wearing underneath - "I'm going on a date later, okay, don't judge!". She gets on her hands and knees to make sure she's cleaning the whole thing off, tits jiggle from the motion of her determined efforts. "We're almost there, we can do this," she says looking up at you, completely unaware of how pleasant this whole experience is for you.
