Kelly alters the shirt while she's waiting

Kelly took a step back from the apparatus so she was out of Isabel's line of sight. As the unaware girl kept lifting the weight, Kelly executed the next part of her plan. She took out her scissors and began cutting Isabel's t-shirt. First, she removed the sleeves, and then removed nearly half of the material from the bottom of the shirt, making it into a crop top. She placed the altered shirt in her back pocket and resumed watching her prey. It didn't take very long until the sabotaged bra straps snapped, and Isabel looked at her shoulders and gasped.

"My bra straps just snapped!" Isabel whined.

"So?" Kelly asked, suppressing a smile.

"If I sit up, its going to fall, and I'll be topless!" Isabel cried.

"Look, let me take it off. I'll give you back your shirt, and it should be fine." Kelly said.

Isabel nodded. She acted like nothing was wrong as she lifted her back off the bench. Kelly unhooked the bra and removed it, finally rendering her naked. She admired her handiwork, seeing Isabel naked and ****. She could just leave her like this right now, but then she would be aware of what she'd done. If she gave her the shirt, she can possibly have more fun at her expense...
