It happened at the gym. Mike had been lifting weights, and Julie was swimming in the pool when it happened. A strange electrical surge swapped their bodies. Neither expected anyone to believe what had actually occurred, so they agreed to try and pretend to be the other until they could find a way to switch back. Mike walked cautiously into the women's restroom. He felt a little aroused upon seeing women in various states of undress. But the way his new body got aroused made him feel a little uncomfortable, so he tried his best to ignore it. He found Julie's locker and opened it with the combination she had given him. The uncomfortable feelings returned as he took off her bathing suit and put on her underwear. The heels were nightmarishly tall, but it was her dress that would prove to be his biggest difficulty. It was so tight! He struggled to zip it up over his large breasts. It was funny, but up until this moment, he hadn't noticed how truly big they were! After a few attempts, he breathed a quick sight of relief when he managed to get the zipper all the way up. His sense of accomplishment was short-lived, however, as the zipper soon burst from the pressure of his large bust.
