"Eh, better just start with one and see what happens," she thought to herself.

So she stripped to her underwear so as not to ruin her already incredibly tight clothes. She then popped the cap off the bottle, grabbed a pill, and ate it. What happened next was astounding.

Almost instantly, Hillary could feel a tingling sensation coursing through her entire body. It felt really good, too. As the tingling grew stronger, she started to swell with new fat. Her impressive belly grew wider and larger, lowering itself slightly more towards the floor and pushing her growing boobs upwards, partially blocking her lower field of vision.

Her ass began growing at a slightly greater pace then the rest of her, making her already overly tight panties feel more like an undersized thong with each passing second. Her thighs followed suit, quickly becoming as thick as whole people, and then some.

Her breasts did receive a good portion of the new weight, but not nearly as much as her monumental ass had gotten. Her breasts grew until they were about the size of basketballs, blocking a good portion of her lower vision.

After about a minute and a half, it stopped. Hillary took a moment to feel her new body. She was absolutely elated that she had reached such a size! But she wondered how much she weighed after just one pill, so she waddled over to her industrial sized scale in the next room, and it read.....600 pounds. A gain of 100 pounds from just one pill! This was great, Hillary still had about 2000 pills left to take! But how to go about doing it?
