Try to bet back her clothes

(chapter originally by worlddominator at writing.com)

Isabel, still clad in just her spandex shorts, marches up to Stephanie and her crew.

"I want to challenge you once again," said Isabel, " to get back for early." Isabel didn't want to risk her street clothes so, she just bared it all for the time being.

"Are you sure?" said Steph, "I don't think you have much left to bet."

"Here's the rules.

1. Outside players can't get involved.
2. The challenges can only be at this gym complex
3. The victor gets to choose one of the loser's remaining clothes. The loser must give it directly to the victor. No actions in addition.
4. The challenges will only end if the loser has no more clothes or the winner decides its enough"

"Sounds fair. Let's alternate who makes the challenges though. Since I made the last one, you get to choose it this time." said Steph coyly.

"Okay" said Isabel "let's try weightlifting. Whoever can do 5 reps of the highest weight wins."

The girls moved to the weight machines. Isabel started with an earnest 60 pounds. Since she had to use both hands, both her breasts were free and perky. Isabel also spread her legs giving a nice view of her pussy although it was covered by spandex. Steph quickly one-upped her at 100 pounds. Isabel doubled the weight to 120. She was heaving a bit after that one. Steph still outdid her at 150 pounds. Isabel tried to do 160 but, she couldn't. Isabel got up and grabbed the edge of her shorts before Steph stopped her.

"What?" said Isabel, " This is the last remaining piece of clothes on you."

"Exactly." said Steph, "but you still have clothes remaining in your locker. I want the panties from there."

"but..." Isabel stammered.

"You never specified it had to be on you." said Steph, " plus if you decide to specify, how will you get your clothes back. They're not on me."

Steph got her and looks like she is going to **** Isabel to go home naked. Isabel gave up on resisting her counterpoints and got her skirt.

Next was Steph's challenge. This time it was farthest on the bikes. Despite her best efforts, Isabel's bare breasts got in the way of her going at her max speed and she lost again. This time, Steph asked for her skirt.

"You know, " said Steph,"this might go too fast, why don't we allow Heather and Kelly to compete."
