"Lets see what happens when I blow into it," said Tiff as she snatched the water balloon away from the still shocked Katie. Tiff found the loose knot that held the water inside the rubbery orb and began loosening it with her fingernails. She was careful not to puncture the fragile latex.
As Tiff tried to undo the knot, Katie could swear that her nipples were being pulled by unseen fingers. The sensations were more pleasurable than painful, and she began to feel weak in the knees. She began rubbing the front of her shirt, which intensified the feeling of fingers tugging at her nipples. Suddenly, the pulling sensation increased dramatically! She let out a deep moan.
"I've got it!", Tiff shouted excitedly. She pinched the opening in the neck of the water balloon to prevent water from escaping. She looked up at Katie, just in time to see her friend's face flush bright red.
"God! Are you OK?" Tiff asked.
Katie just sank to the linoleum floor, breathing heavily. The orgasm had been intense enough, but now Katie had to deal with the sensation of Tiff's fingers pinching tightly on both of her nipples. Tiff dropped to the floor to attend to her friend, and Katie explained the magical connection that now existed between her body and the water balloon in Tiff's hand.
"Oh" said Tiff, a devilish grin spreading across her face, "So you're saying you can actually 'feel' everything I do to the balloon?"
Katie, looking up and still out of breath, said with a note of frustration, "Yes, that seems like the case".
At that Tiff raised the rubber nub to her lips, dramatically licked around the rim, and them blew slowly into the water balloon. She threw a cautious eye at her friend, who was again moaning on the floor.
"Please...", said Katie, reaching out to her friend, "Uhhh..iiitt'ss...toooo..ah...intense". Through the waves of pleasure, Katie noticed that her breasts had grown. She passed a B-cup and was now into the range of a full C. The rubbery sheen on her peach colored mounds had become brighter, and she could feel water sloshing around within them.
Tiff continued to inflate the balloon until it reached the size of a basketball. She cackled as she looked at her friend, whose two basketball-sized rubber breasts were now completely transparent. Tiff could see the reflections of fluorescent lights on the tops of Katie's massive breasts as her friend tried to re-button her shirt and failed miserably.
At the sound of Tiff's laughing, Katie came to her senses and stood up. She was extremely self conscious (they were, after all, still in the girls' locker-room). Anyone could walk in and see her this way; the womens' gym coach, one of her friends, or worse, one of the popular girls who teased her almost daily. If anyone but Tiff found out about this balloon miss-hap, she'd never live it down. "Tiffany Ann Tyler, Give me that water-balloon!" said Katie, sternly. She stamped over to Tiff like a soldier.
Tiff, who had been laughing on and off at her friend's predicament, broke into thundering peals of laughter as Katie goose-stepped towards her. The motion of her steps was causing the small amount of water originally inside her breasts to slosh around loudly. Not only could Tiff hear the ::slosh:: ::slosh:: of each step, but, because Katie's rubberized boobs were so transparent, she could actually see the miniature waves crash from side to side.
She was laughing so hard, and slapping her hand on her knee, that she lost her hold on the water balloon. It zoomed away, propelled by a jet of air and water, soaring over lockers. Both girls followed the wild, aerial path of the balloon. Katie was unaware that her breasts were shrinking by the second.
The balloon landed with a ::squish:: on...
