Later that day, Jessie got home, had dinner with her Dad, and ran to get a bottle. She'd decided to try 'Muscle'. It smelled different this time, more like a man's deodorant. "Weird", she thought.
Getting out of the shower, she felt very hot all over her body, and gasped, reaching for the sink to steady herself. Her hands! They looked larger, and her forearms were getting more muscular before her eyes!
Looking up, she watched as she got several inches taller, her frame adding bulk in the form of powerful muscles! "Holy shit!", she exclaimed, as she now had a bodybuilder's physique. She didn't look grotesque, just really buff, but when she flexed, muscle she didn't even know she had made their presence known. She felt fantastic, and had the urge to go work out in the garage!
She was forced to walk to her bedroom naked, careful to not let her Dad see her, as her clothes no longer fit her. Luckily, the laundry room was on the way, and she got some of her Dad's clothes to wear, which fit snugly on her body.
She then walked by her Dad on the way to the garage.
"Oh hey honey, going to work out? We're going to have to buy you new clothes if you keep bulking up!" He chuckled. "My old things are starting to look small on you!" He waved and smiled.
"Wow, he really doesn't think anything is wrong", Jessie thought.
In the gym, she started working out with her Dad's heaviest weights. It felt amazing, and she didn't even care that she worked up a sweat. She took another shower before bed, and as she lay there, she thought about what she would do in the morning.
