"Why don't we turn into sharks?" said Connor. "They have that new shark exhibit."
"That's a good idea." said Jeremy.
"I'm in." said Ryan.
The boys ran over to the shark exhibit. Making sure no one was watching, they climbed the fence that led to stairs to the top of the fish tank. The tank itself had pathways through it so that the zoo patrons could actually walk through the tank. Luckily, the exhibit didn't open for another 10 minutes.
"We'll have to do this quickly, so that we don't get killed." said Connor. The boys took off their clothes. Naked, the brothers jumped into the tank. They swam quickly towards the nearest shark. Luckily, the sharks were trained to know the difference between people and food. The brothers placed their hands on the shark, getting the familiar tingling sensation throughout their naked bodies. The boys swam away from each other, because they were incredibly turned on by transforming and, they were teenage boys.
Connor felt his neck tingle, and felt slits open in his neck, allowing him to breathe water through his new shark gills. His neck began to thicken, until it became an extension of Connor's head. Connor felt his new shark neck with his hands, groaning with pleasure as he felt his hands begin to shrivel. They began to thicken, forming fins. Connor groaned with sexual pleasure as a dorsal fin began to form on Connor's back. Connor looked down and saw his legs lengthening, forming a single appendage. Connor could hear the cracking of bone as his skeleton began to rearrange and reform itself into a sharks'. Connor groaned again as his spine squished, extending into what had been his human legs, and was now his shark tail. Connor groaned with pleasure as his feet began to distort, flattening and extending. His toes sucked into his body, forming the tail of a shark.
Connor began to stroke his erect penis as his hair began to pull itself into his head. His pubic hair followed. Connor's human face suddenly began to extend, bones cracking as his face pushed outwards. Connor's mouth grew and grew, his teeth sharpening, and being joined by new, shark teeth. Connor's vision changed to a sharks'. Connor groaned once again as his skin began to thicken, and change, turning dark grey. Connor's dorsal fin pushed out more, as his shoulder blades disappeared into his changing body. Connor's buttocks smoothed over, as did his navel. Connor's penis elongated and turned grey like the rest of his body. His penis and testicles sucked into his body, leaving only a slight lump where they had been. Connor's arms finished their change into fins. Connor had become a shark. He began to swim, meeting back up with his brothers. They swam around, loving their powers, and loving being sharks.
