There's only one patient at the Chrome Center of Experimental Medicine, and they're displaying very unusual symptoms - thick, gelatinous, black drool, and an unusually heightened libido. Nina climbs out of their hospital gown and onto a medical exam table, the black slime from their throat quickly becoming too much to hold back and falling on their little tits. The more they rub the goo on their skin, the hornier they get, the more they fuck their mouth with their fingers and the more spit puddles out of their throat. Before long, Nina's so overcome by lust that they have to fill up a hole other than their throat - grabbing a glass toy, with a dental gag holding their mouth open so the black drool keeps falling, they fuck themselves to an orgasm, covered in their own filth.
