Em shrank and shrank, moaning as she went. Mary continued to kiss her and bend further and further down. Soon, Emily stopped, the size of a female chimpanzee.
"Wow." Said the arroused, tiny Emily. "That was so intense! I need more!!"
Before Mary could react, Emily grabbed the eye dropper, retrieved the largest amount of potion yet and drank it down.
"Em!" Said Mary, worried as to what would happen. "That was a lot, you might go microscopic and then I wouldn't be able to find you!"

"You'll see..." Said Emily.
Emily ran towards Mary's giant form. When she got to Mary's huge, wet pussy, she quickly crawled inside it, making her way to the womb. Mary screamed with surprise and pleasure as Emily poked at the inside of her sensitive pussy. She continued up the shaft until she reached a wider space, which had to be the womb.
