Stew noticed Jenny walking off by herself and asked "Where are you going Jenny?"
Jenny said "Well since I'm this big i'm going on some of those bigger water slides. I'm tall enough right?"
Stew thought "That guy just wished for her to grow. This is a transformation amusement park, it may be high tech and powerful but it's not like it can bring the dead back to life... I just wasted a wish..." then said "You know what sure, let's just be careful that we don't change into anything we don't want to be."
Jenny thought for a second and said "Yeah... I don't want to get too much bigger..." cupping her large breasts. The two however managed to get to one of the larger water slides. On the walk up they saw all sorts of crisscrossing tubes of different colors, a few slower areas in the middle, and of course the walk was pretty long.
"Well at the very least you being bigger made you complain less about the walk... Stronger legs and all."
"The more work it takes to get up, the more fun we can have coming down!" She smiled making Steve smile as well. The two got to the top where there was just a bunch of slides of different colors. Jenny excited rushed and went down a blue tube as she liked the color blue.
Steve tried to follow, but her tube was sealed so he just got into the one next to it, a pink tube.
Now Steve had to admit this was a ride for a thrill seeker. The technology made it so at the very least it seemed like he was immediately falling down the tube at terminal velocity. For the first second it seemed almost like a pure slanted fall, but then it started twisting and turning, and Steve just couldn't keep himself from screaming at the top of his lungs. As the fall ended he could of sworn his screams were getting higher pitched if he wasn't so busy being thrown around this watery hell hole. Then after a few minutes of falling down he was tossed out of the tube into the air and then fell into a large pool of water. Instinctively he swam up and took a gasp of air. Looking around Steve didn't see anyone, least of all anyone who looked like they could potentially be Jenny. There were some additional tubes to slide down in, but Steve couldn't see any blue or pink ones which left him with one question. What did the pink tube do? He already could kind of tell with how the water currents was flowing around his body, but he patted his crotch with his left hand and groped his right boob with his right hand. Looking down he saw that he was a woman in a bikini that kind of resembled her once trunks. Steve's heartbeat raised and noticed there wasn't any cameras here or any person. Jenny now probably a guy was going downhill at a rapid pace (maybe even going down a third set of tubes), and while Steve had been faithful she still had some sexual urges. For a few seconds she slid down her bikini top, and massaged her C-cups and tweaked her nipples enjoying the sight and feelings of her boobs. Then getting a bit more level headed put her bikini top back on, and then looked at the tubes she could go down and went down the....
