Coach hurried away from the field house after he locked the door, he headed straight for the gym, but went passed it. He unlocked the door to the Natatorium. Looked around, then went inside locking the door behind him. He stepped out of his sweat pants thereby giving Chad a clear view of the blue water sparkling in the pool. He kicked off his shoes. Then he pulled his sweat shirt off. Coach Sinclair ran toward the pool, and jumped. He pulled his knees up to his chest obstructing Chad's view, and yelled, "CANNONBALL!"
Splash!
Chad is underwater. Coach is treading water. Chad is holding his breath. Come on, Coach, I'm going to drown!
The coach seemed oblivious to Chad's screams. The coach started swimming laps. For a big man, he was still quite athletic. Chad wickedly thought that all his fat probably made him more buoyant.
Eventually, Chad realized that even though he had been human, he was now really a Speedo, and Speedos don't need to breathe. Chad suddenly felt warmth filling him. It took a second, but he realized the coach was peeing in the pool - peeing into his Speedo. Peeing into Chad, and he could taste acrid urine mixed with chlorinated pool water, and it made him feel useful. He knew it was sick for a human, but he was a Speedo wasn't he. It wasn't that Chad was forgetting he had been human, or maybe it was. Chad knew after what had happened the chances that coach would ever change him back were probably zero.
Chad hears a splash, someone else has joined Coach Sinclair in the pool.
