Not so much as possess, as control her

Lisa woke up after a lovely nap, feeling refreshed, if not a bit weird she shrugged and decided to go about her work. Little did she know, she wasn't entirely alone.

The slime was still just as awake and aware as it has been in Lisa's stomach, but could now see clearly! The slime could only see what Lisa saw, and it couldn't move or do much inside Lisa, but it was a start! As Lisa was stamping books, her cleavage came into view. The slime was curious about it, and wished it could feel further.

As if by puppet strings, Lisa suddenly grabbed one of her boobs and gave it a squeeze, surprising both her body's occupants.

"What the?" She uttered instinctively. The pleasure of her boob caused her to feel aroused, which somehow caused the slime to feel it to, and it wanted more.

"Well, maybe a quickie!" Lisa decided to close her book and take off her panties. Opting for a quick bout of pleasure, she stuck a finger into her pussy. It somehow felt twice as good as she was used to, and decided to continue. Using her electro powers ever so delicately, she gave her pussy a slight twinge of pleasure. She followed this up with a brief nipple-pinching, before she climaxed over her chair. Opting to hide it, she put back her clothes, dried her hand and continued her work.

Realizing it was responsible for Lisa's behavior, the slime wanted to do some more with her body. She could return to the wilds with her other slimes, or just continue work as Lisa was doing and merely just guide her into doing what the slime wanted. Or maybe masturbate again! The choices were endless
