"Now, Sarah," Karyn started to say, but suddenly her eyes went wide. "Whoa! What are you doing, Sarah?"
"Just showing my appreciation," the girl's voice came back to her.
"Well, maybe..." Again, she stopped what she was saying. "Oh, my," she said weakly.
"What's wrong, Karyn?" Jon asked. "What's going on?"
"It's Sarah, Jon," she answered. She had back up against her locker. "She's..." She moaned softly. "She's rubbing up against me."
"Rubbing up against you?" Jon repeated. "So, what's... Oh." He had just remembered where...and what...Sarah was at the moment.
"Yeah," Karyn agreed, as another shiver ran through her body. "Oh, indeed."
"But how can she do that? She's just a pair of panties, right?"
"Remember what I said when I changed her? I said she would have 'limited' movement." She slowly slid down the front of the locker and sat on the floor. "Ooooh! Looks like she's not as limited as I'd hoped for."
Sarah's voice cut in. "Why, thank you, Karyn."
Karyn suddenly cried out loud. When she got a little more control over herself, she said, "You know, she's pretty good at this. I think she's done it before." A giggle came from between her legs.
"Karyn, get a grip on yourself. You've got to stop this."
"I'm trying, Jon. Ahhh! It's just a little hard to concentrate with her... Oooh! Well, it's just hard to think, okay. I'm not made of stone, you know."
"Well, maybe it would be better if you were," Jon said, a little angry at how Karyn had let things get out of control.
Karyn, meanwhile, could feel herself getting ready to explode. As good as what Sarah was doing felt, she still thought it was wrong to let her do it. But everytime she got ready to put a stop to it, Sarah would hit her again, and she would have to start all over.
"Believe me, Jon," she said, trying to catch her breath, "right now, I wish..."
