The boy looks at his hands and sees that his flesh is darker in color, swiftly approaching black.
He steps away from his friend Jay who is slowly shrinking as a little string emerges from his leg. Jay gently floats the ceiling and makes a little bump as he hits it.
"My hands..." The boy says as his fingers melt together with the crunching squeaky sound of latex being pulled tight. His fingers flatten and his thumb merges in to them ending his arms in flippers. The dark color spreads up his arms slowly and you watch from your shadowed corner of the room as the boy grunts a little and wrapps his strange arms around his chest.
"Ungh.." is all he says as his back arches. You see a hump forming under his shirt, pressing upward and pointing toward the ceiling. Its tip is being mashed down by the boys t-shirt, but it continues to swell. The boys chest appears to be swelling too and his shirt is having a hard time standing up to the stress.
RRRRIP!
The shirt splits down the sides and falls to the floor revealing the boys upper torso. His body is dark grey, turning black and shiny as it swells a little. At his back a huge pointed fin is growing from his spine. It is shiny and black becoming see through as it grows taller.
The boys arms on the front are turning white, and his chest is starting to lighten. A white belly for the killer whale he is becoming. You watch in fascination feeling yourself becoming a little aroused too, tenting your speedo gently in the front. You pay no attention to yourself though, rapt attention on the boys change.
His pants bulge in the back and the boy grunts a little feeling the pressure of them as they tighten. He fumbles with his button and zipper but he has no fingers and his flat fin like hands just squeak uselessly against his crotch. You can see the front of his pants is bulging too, but its being smashed back as his tail emerges.
RRRRIP!
His pants split in the back as his flat tail pushes outward. The waistband now torn he pulls his pants down entirely and steps out of them now standing naked before you.
Mush like his friend did before, the latex of his tail is reaching under his legs and spreading up his crotch and on to his belly. His genitals are slowly coated and the boy grabs them and sighs feeling the heightened pleasure.
Behind him, his thin tail swells and bulges on the sides right and left becoming a long tail fin. His arms are no longer able to reach his crotch as they shrink inward and he paddles the air with them helplessly.
Face now black latex, and white colored markings, his nose pushes foward and you hear a moan escape him as his mouth seals shut and his neck swells to hold his large orca head.
His legs are the last to go, smooth and black they shrink in to his swelling body as he is now a huge orca balloon filling the room. A small string emerges from his tail, and the boy stops moving.
Shrinking occurs quickly with a squeaky rasp as the balloon changes size, and then floats helpless to the ceiling.
You let our your breath, realizing you were holding it the whole time. That was amazing, but its time to go make a new friend you think. Its time to head over to Jack and get a personal tour of the island, and with some luck a personal tour of Jack.
You turn to leave the hall of mirrors.
