The young Filipino beauty sensed a tingle throughout her naked body. Nicola tries hard to have a grip on her breasts and pussy, yet she's struggling to have them covered.
"Wha... what did you do to me..." Nicola slurred.
"I can't believe that worked!" Sam sounded surprised. "I'm not such a bad student after all. Look! You are really becoming a mouse!"
Hearing that, she felt some furry hair on her hand trying to cover her breasts. She slightly removed her hand, and saw short, pale gray hairs were covering them. It was expanding through her added sets of breast. The gray change went through her brests and towards to hips. Touching there, small thin flesh, not with hair came out from her spine. It soon got as long as the rest of her body, forming a tail of mouse.
At the moment, she was only about a foot, and still getting smaller. Her legs and arms got shorter either, make her difficult to stand upright with two feet(two paws, soon). Lastly her ears magnified, and head became fully mouse. Now Nicola was only 6 inches including her tail that about half of it.
She couldn't help but stand there frozen in surprise. If she wasn't surprised, she did not know how to walk or run properly as a mouse, so it would be same. "A, Am I a mouse??" She thought.
Sam was crouching and looking at her. "It... actually worked! Now you mouse lady, come to het out of here."
