No one was saying anything for a bit, but Zack asked "This time how about we drink one at a time? The changes seem fast and it may be more interesting."
Cody nodded and said "Should work fine. I guess I'll go first." and knocked back a tube he grabbed from the pile after mixing. He then felt the gurgling and tingles as his body went through a few growth spurts and got a little more hairier as the 16 year old climbed into adulthood, and now could legally drink alcoholic shots.
Tony said "Cool, now let's see what I'll get." and then selected another shot and knocked it back. She then got a sense of vertigo as her limbs and torso elongated a bit as her somewhat curvy figure got stretched out into more of a stick as she grew half a foot.
Zack whistled and said "Woah foxy momma! Looks like your tall enough for me."
Tony sighed and said "I'm a dog not a fox remember? Bitch?"
Zack chuckled and went to get his shot and drank it as he said "Now ready for..." and then he found himself looking upwards as he shrank back down 6 inches.
Tony chuckled and said "Easy come easy go, right shorty?"
Jeff said "Hopefully I'll be a guy or a teen again." as the tween walked over to the box and remixed the already mixed box of tubes and plucked one out. One sip later and Jeff felt herself shrink further, but more than that. At 11 her chest was undeveloped, but there were some buds. She wasn't getting shorter as she could feel what little hips and chest she had completely undeveloped. Jeff upset blurted out "No Fwair! Me big boy!"
Cody and Zack were chuckling, but Tony grabbed Jeff and put the little girl on her lap and said "Come on, and calm down. You're one of us. So all you need to do is drink the cancellation potion and things will go back to normal."
Jeff angrily said "Me no Qwuittwer! Me go again!" and thrashed a bit in Tony's lap.
Cody said "Another round then!" and gathered the vials that were refilling and started shuffling them some more. "Whose up first?"
