Riley slowly saunters over to the scientist, and seductively rubs her naked upper body up against him,as she dumps a healthy dose of formula in his coffee.
"Do you have a lab coat I can borrow to cover myself, so that I don't have to stand around exposing myself to the world in just a diaper?" she whipsers seductively as she nibbles his ear."I do just so love scientists, you guys get me so hot! If you'll just clear the lab, I'll make it worth your while after changing."
"Uhhhh, yeah...yeah...uhh, sure whatever you say,"he gasped excitedly.
Grabbing his coffee he slugged down the contents, and shewed everyone out of the lab.
When Riley returned, she found a 3 month old baby on the floor.
"Ooooohhh, just as I planned," she purred, and proceeded to gather up any and all bottles of the various formulas as she could find and head on out.
