The liquid Mary just drank began to work slowly on her. Probably because it didn't have much to change. Mary felt her body grow larger by a good number of inches. She also felt a new strength come as some of her soft fat hardened into new muscle. A tingling sensation started on her lower jaw, and Mary felt two teeth push their way up and over her upper lip and snout. Looking down, Mary could see two large tusks on either side of her pink snout.
Mary was having a sinking feeling about these changes. It wasn't a sinking sensation that Mary felt, but a pulling of her genitals. She felt a growing snake of flesh under her and attaching to her lower belly. It gave off wave and increasing wave of pleasurable feelings.
With a guttural grunt, Mary knew she was no longer female, but a definite male. Mary could use this to her advantage, she reared over to face Jess, a mere cat, quivering on the top of the couch. Mary grunted and gave a show of her tusks.
Jess was not liking these changes at all. She had to do something, and quickly.
