You surgically removed 2 girls' brains, and they are somehow still alive. Now their foreheads are open, with hinges on the back of them

Girl 1: Muhhhhhhh

Girl 2: Uhhhhhhhh

*They are drooling endlessly, prolonging their noises for eternity, and staying completely and utterly still. *

You watch the drool touch the girls' breasts, and in turn, make them dumber as their breasts grow. The drool then reaches their butts, which make them grow too, ripping their clothes.
