Always stretch first!

"What first?" Britney asked Vanessa. Meanwhile Mark sat down, deciding to get a good place to watch the show. He also wanted to hide his raging hard on. This was his girlfriend, her sexy friend, and the surprisingly curvaceous debutante all scantly clad, practically preforming for his private audience! Of course he found his body responding! He grinned, excited to see what was in store.

"First things first." Vanessa said. "We've got to stretch before we do any exercise."

"Too true." Said Britney.

"Alright Lauren!" Vanessa put her arm around Lauren. "Let's get started!"

Then she leaned in and whispered to Lauren.

"Play along or your fat ass is getting spanked in front of Mark." She hissed into Lauren's ear. Lauren's jaw dropped. She couldn't really mean it?! One look at Vanessa's smirk though, and she knew it was the truth. She'd have to play along with this humiliating scheme, or risk greater humiliation!

"Great!" Vanessa said, pushing Lauren into line with her and Britney. "First, touch your toes."

Both Britney and Vanessa, two limber athletes, easily touched their toes. Lauren bent, but could only reach half way down her shins.

"Come on Lauren, stretch!" Vanessa urged. Lauren tried harder. She grimaced, feeling the spandex shorts riding up farther as she bent. It was so wedged up her ass she was worried they'd get lost!

"She can't do it." Vanessa shook her head.

"Must be that gut getting in the way!" Britney laughed.
