Dana was getting uncomfortable during her workout session. Her clothes were too tight, and she was afraid that she was going to pop out of them. But it didn't seem to bother Kelly. As their workout session continued, she seemed to get more and more excited. It seemed like the spell was making her more attracted to Dana as time worn on. Soon, she would ask Kelly back to her apartment. Very soon, in fact, as she didn't know how much longer her clothes would stay intact.
Kelly was enjoying her workout session with Dana even more than working out herself. The small girl's body was really responding to the exercises. Each lift and pull seemed to cause her muscles to grow and expand before her eyes. And as her body blossomed, Kelly was getting more and more excited. She eagerly pulled her from one machine to the next, eagerly awaiting the effect each machine would have on her muscles. The squats and leg presses expanded her thighs and calves. The bench press caused her pecs to swell. The shoulder press expanded her deltoids, and caused her back to stretch wider. Crunches made her abdomen tight with prominent abdominal muscles. And, of course, the barbell curls caused her biceps to grow. There seemed to be no end to her growth potential, and each change seemed to arouse Kelly more and more. He would have to get this girl's number and track her down later. She was unbelievable.
Dana couldn't believe how hard Kelly was working her. It was like she was obsessed. She was more surprised that she could keep up. She didn't realize she had that much stamina. She didn't feel tired at all, and the workout was actually making her muscles feel very good. She would have enjoyed it even more if her clothes weren't so tight. She desperately wanted to go change into something else in the locker room, but she didn't want to disappoint Kelly. She hoped that Kelly would get the hint when she took off her shoes. Her shoes pinched her swollen feet, and she had to remove them to relieve the pressure. But Kelly didn't seem to notice, and kept working her in her bare feet.
The final straw was Dana's top. As her chest continued to grow wider and thicker, it began to stretch tightly across her chest, making the fabric thinner and weaker. Small tears had developed unnoticed during the vigorous workout, and they finally yielded to Dana's growing body. With a loud snap, Dana's top popped off of her body and across the room. Embarrassed beyond belief, Dana covered her bare chest and ran to the locker room.
Kelly was surprised, and a little embarrassed himself. He had pushed the girl too hard. He went to the locker room to apologize. The girl was just too attractive to let her get away. When he entered the locker room, he was shocked by the sight before him.
