Slowly the purple horns spiral their way out of the boys forehead and you hear him gasp in horror.
He reaches up quickly to grab them, looking in the mirror, a loud squeak confirms they are real as he mooshes them in his fist. He tugs at them and they dont budge but his face makes a little wince of pain. They are firmly connected.
"Dude whats wrong?" His friend steps over and peers around his friend to see his face, and then bursts out laughing. "Hahahah you have horns! Purple horns!" His friend hasnt noticed that his balloon is also missing.
A rip comes from behind the horned one and a small point emerges from his ass, splitting his pants as it does so. The boy yells in terror and spins around trying to see it in the mirror as he feels his tail pressing outward. His friend is in hysterics laughing so hard he is turning red.
"Help me! Im turning in to a balloon like that one that guy gave me! Help! urgh..." his friend grunts as his waist swells a little. In seconds his pants are ripped clean off by the combined force of his emerging tail's little spike protrusions, and the fact that his chest swelling has torn the waist band to his jeans.
He stands there naked, with his underwear waist band still around him like a belt with tattered white rags hanging from it. Behind him his shirt is starting to rise, making him look like a hunch back. In front of him his tail is slowly blending in between his legs as it swells and the purple rubber is starting to creep forward.
"Oh shit! No! Please no!" The boy grabs his dick at the base and pulls his testicles up as if trying to keep them away from the rubber creeping up between his legs from his large purple tail. His chest is very swollen and starting to take on a purple hue as well.
"What is it? Dont wanna be a dragon balloon? I wont pop you I swear!" His friends voice comes from behind him but he is too busy to notice.
In his hands he feels the creeping latex reach his testicles and spread up them, he is powerless to stop it. They become smooth in his hand and shrink back between his legs as they receed. The same purple rubber creeps up over his shart and then closes with an audible hissing sound around the tip and it inflates a little, the boy takes a quick breath as he feels the pleasure of his touch. Then his swollen member starts to receed as well until he is smooth between his legs with his fat tail merging in to his fat belly perfectly.
His wings have torn his shirt off completely as they emerge behind him and unfold with a pop, inflating to their full extension.
He turns to his friend just in time for his mouth to seal shut, his face feeling tight as it pushes forward becoming a fierce dragon snout as his hair falls to the floor around him unable to stay on his now latex head. His hands are the last to go. Arms shrink, fingers merge to leave him with only three, the swelling stops and they are coated with purple latex.
Before the other boy stands a six foot latex dragon which takes a single step forward before it becomes translucent and motionless, shuddering a little as it does. It falls gently forward and hits the ground with a little poomp! noise, shrunken to its final size.
"Holy crap Jay... are you.. Jay?" The other steps forward to pick up his friend but as he extends his hand he finally notices the changes that have also been happening to him.
