This was the most amazing thing I've ever experienced. There were so many things I could do...but first I had to get some friends over. I called around, and only two were able to stop by.
First there was Jenny. I met Jenny here at college, and we grew relatively close very quickly. She was 5'4", 34C, nice figure. She had straight brown hair which she highlighted with blonde, green eyes, small button nose, light skinned.
The second person was Tim. Tim was 6'4", brown hair, black eyes, relatively good looking. In his spare time, he worked out. A lot. he was probably the strongest guy I knew, and he looked it too.
Eventually, they were both at my dorm, and we talked a bit about school, and other random stuff. I wasn't really paying attention.
"So..." Jenny started. "I don't get why you wanted us to come over so badly?"
"Well..." I started, unsure of how to go about explaining this without sounding crazy. "I'll just show you." I walked to my room, and grabbed a bottle. I brought it back, and opened it. "Now, watch me. Keep looking at my body, and tell me what you notice. You ready?"
They both look confused, and nodded. I took the cap off the bottle, and took a swig, wiped my mouth off, and waited. After a few seconds, Jenny looked toward Tim. "Don't look away, you'll miss it!" I said. They both looked back, just as my body started to growing.
"Oh my..." Came from Jenny.
"Holy shit!" Came from Tim.
"Yeah..." I said, watching my body slowly gain mass, growing taller, my breasts filling up, distorting my shirt a bit, showing more of my stomach. I knew I had to be bigger than Jenny now at least, and I was about 5'9".
There was a pause as Tim sat in his seat, mouth open, and Jenny standing, a few steps back from her seat, with her hands over her mouth with a worried look on her face. "That's....amazing!" Jenny said. She took a few steps closer to me. "Mind if I try some?" She asked.
"That's what I invited you guys here for!" I said, and handed Jenny the bottle. She looked at me, then back at Tim, who was still speechless, and with a concerned look, waited for Jenny's action. Jenny took a big gulp, and handed me the bottle again. There was a pause again, and then Jenny's body began to swell, the same way mine did. Her already slightly bigger than average breasts began to swell more, filling up her bra and shirt, as she inched taller and taller.
She looked down at her breasts, as they swelled before her eyes, bulging out of her bra as the floor seemed to move farther away from her. Her ankles and stomach began to become exposed, and her growth slowed to a stop, and she was now 5'8", with about 3 inches added to her breasts.
As she cupped her breasts, I looked at Tim, and held the bottle out. "Want in on this?" I asked, eager to see, and hoped that, it would work on guys.
Tim stood up, grabbed the bottle, looked at it, smelled it, and nervously took a gulp as well. Just because Tim is already a big guy, his gulp was bigger than Jenny's. he handed me the bottle, and we all watched with anticipation, Jenny's hands still on her breasts.
Slowly, Tim began to grow as well. We both look up at him. At the start of the day, Tim was 10 inches taller than me, 11 inches taller than Jenny. Now he was 7 inches taller than me, 8 inches taller than Jenny, but this potion would end all that, as he started to inch upwards, farther away from us again. It obviously affected him differently, as we could all see his muscles were swelling larger all over his body. Everything from his calves up to his shoulders were building muscle, growing taller with his body.
His clothes tightened all around him, shortening and covering less skin around his waist, arms, and ankles. It eventually ended, with him at 6'8", but the amount of muscle he added was substantial. We all looked in awe, me and Jenny looked in lust as well. "Holy crap..." He said, almost under his breath. He reached his right hand, which was also bigger, down to his crotch, and felt around. "That even got bigger!" He said. I laughed, and Jenny smiled.
