Deeane just comes back from her daily workout and she's still wearing her gym outfit. She doesn't notice the bunch of tiny people on the floor right in front of her. She accidentally crushes all of them while just walking through the room - they're so tiny she doesn't even feel them!
Deeane is a professor at the local university and she noticed this student checking her body out all the time. She's going to give him more than he asked for! She shrinks him to doll size and duct-tapes him to her leg - with his head touching her pussy. Now she can walk around and gets her wet pussy massaged by his tiny head - and no one can see him under her skirt!
