Tony pushed his arm in up to his shoulder and contorted his wrist painfully to begin the process of shutting off the water.
Above him the sounds of the muffled grunting and squeaking as his friends face founded and stretched had been totally replaced by the steady hiss of the shower pouring more water in to him.
With a final and painful lurch, Tony felt the handle on the wall cease it's spinning and lock tight. Sure enough the hiss stopped, and the water had certainly ceased to flow. He looked up at his friend, and saw that what remained of Chris was now just a huge semi transparent balloon that was roughly flesh colored but a little paler.
"Are you still in there?" He said tot he huge sphere. No response came, and Tony recalled what it was like when he had changed. The feeling of being totally immobile but totally aware of his surroundings. He knew inside Chris was indeed trapped in his new form, and could probably feel him.
Tony pulled back, trying to free his arm from where it was pinned against Chris and the wall of the shower. His friend had swollen so much he was wedged in tight as a drum, and pushing his hand against the tight skin of rubber just made his hand sink in a little and only cause his arm to become more pinned with the new pressure.
"Damn" Tony said giving up his struggle. "I think I'm stuck..." He looked down and realized that after his shower and balloon body swap experience he was still naked. This was extremely awkward, and what he was going to do next was even more so.
