Sliding along, Lisa notices a man sneaking into an alleyway. Quickly moving after him, she finds him making some kind of deal with a younger kid. This doesn't Intrest Lisa particularly, and she sneaks up behind the man, forming herself behind a dumpster as he finished his business. As he rounded the corner, she grabbed him and pulled him face-first into her slimy breasts. Lisa hears his muffled yelp of surprise as he pushes away from her breasts wildly. Sinking him further into her chest, Lisa starts to wrap herself around the man, sliding into every nook and cranny. At this point the man is starting to melt away inside of Lisa, and she pushed his body towards the sphere of opaque green slime that was her core. The man stopped resisting, and her core started to accept him into itself, bloating it with the mass of a fully grown man. After a few minutes was stretched pretty thin over her gigantic core, which was starting to slide out of her "navel" and onto the ground. Part of it slipped inside her, returning to its place in her lower "abdomen" and the core egg took on a light blue coloration as it separated entirely and flopped to the concrete. The opaque surface cleared up, revealing a deep blue core, and it melted into a puddle on the ground.

Emerge, revealing the blue slime girl emerging. Lisa watched in fascination as the head was followed by shoulders and arms. A pair of breasts, slightly smaller than her own, followed, the core nestled safely in her left tit. Finally, the new girl finished forming, with a support which was much more curvaceous than Lisa's. Opening her eyes, she looked to Lisa. "Hello Lisa, I am Kate! Nice to meet you!" She said happily, hugging her firmly. Now, what next?
