Just as Shenzi dunked her head into the troth her belly started to stretch out a little closer to the ground. It also only took a few seconds for the chemicals to produce there addicting affect, making Shenzi NEED the food.
"Oh man, this stuff is better than FRESH gazzel" Shenzi said between mouth fulls of food and continued on her gorge.

"Do you know how long in the slammer we will be in if anyone discovers our little 'experament'?"
"Yes, so why don't we drown our worries with a round of drinks, on me."
"Alright, let's just hope this dosn't go too far."

Shenzi's form began to round out even more as fold formed on her side and back while her neck plumped up to give her a large collar of fat. Her belly hung down and touched the cold metal while her rear end grew wider and wider. When she finnished the troth she was outragiously fat, sitting on her large rear end causing some of her spots to distort and get larger.
"Aww man, is that all" Shenzi complained to herself as she looked at the troth.
The troth then filled itself again, causing the still hungery Shenzi to plow into the troth and start stuffing her face.
