Mary grabbed the vial marked breast grow and wondered how much she wanted to take. "Oh well, I'm gonna go all in," Mary said to herself as she upended the vial's contents into her mouth. Walking over to her couch to await the change. In mid step the potion kicked in and sent an electric shock through her body, causing her to double over and gasp.
"Ok, it is definitely working now-OH GOD YES. A second shockwave rocked her, feeling like an orgasm as she stumbled to the couch feeling her center of balance shift. Mary gasped and moaned at each increase in cup size, feeling her t-shirt stretch with each surge.
Mary began to bite her lip in pleasure, as she grew. When she reached DD her breasts began to pull down slightly due to the added weight, creating a food in the shirt as the breasts grew. Eventually the growth stopped at an astonishing F cup, the fabric hugging the breasts giving a very clear image of her erect nipples. Mary slowly stood up checking her balance and started toward her mirror thinking that the change was finished when the second stage began, causing a pulling sensation in her nipples. Underneath Mary's shirt her nipples and areola expanded to match her breasts all the while making Mary go red in the face from the ecstasy and drove her to an actual orgasm that forced her to her knees. Panting, Mary made her way yo the mirror and tugged her stretched tee off. Her nipples had grown to 1 inch long with a half inch diameter. The areola had expanded to 5 inches across in her massive mammaries.
"Now this I can get used to," said Mary grinning, "could do with out the extra weight though. It's gonna take some getting used to, or does it?" Mary grabbed the vial case from the living room and brought it to her bedroom to lessen the effort of checking after each vial and searched for the one she needed. The case had drawers on it that when she pulled out extended much farther than it realistically should have in the case, meaning there were more possibilities than she originally thought.
Eventually Mary found it, one labeled 'MUSCLE Grow and took about half of it.
Deciding to stay topless, Mary watched herself in the mirror as the change began. Her biceps felt like they were flexing and unflexing, becoming more toned. This feeling spread throughout her body on each muscle group giving her the body of an acrobat; compact and toned but not like a body builder. The uncomfortable feeling of supporting her breasts quickly disappeared and soon Mary's mind was racing to think of what to try next......
