DESCRIPTION
"Reverse of an earlier piece you did.
Cute scientist girl shrunken down and naked inside a cage with a cute mouse girl. The scientist is smaller than the mouse girl by about two heads so the mouse girl is easily able to playfully pin her down and straddle her.
Mouse girl is grinding herself on the scientist while blushing in arousal while the scientist has a bashful expression."
