Amber gives Marc something to think about.

"I'm not touching that thing!" Cheryl cried out, reeling back.

"Oh, we don't need to touch anything..." Amber said as she used Marc as a platform to climb out of the water.

"Hey, you crazy witch! What do you think you're doing?!" Marc blurted out as he buoyed from the increase in weight.

Amber steadied herself as she mounted their prisoner by the chest. She nodded to Jessi to balance his legs so that she could lean closer to where Marc could see. "You're a very lucky boy, Marc..." she said as she lower her body steadily in front of him. Her legs squeezed tightly around his shoulders to keep her still as the other girls held the two afloat. "You get four beautiful girls to admire up close and naked..."

The blonde started to gyrate her hips on Marc while she dangled her breasts over his head, "We must make you so hot and wet..." Amber chided.

"Omg, is it twitching?" Cheryl looked on in disbelief as Marc's throbbing dick came to life.

"Shit, Amber, he's ready to explode already!" Jessi laughed.

"Oh... but if you pop this early, you'll miss out on a very sexy show..." Amber teased as she ran her fingers through his hair and continued her sensuous sways. Marc merely made a weak groan in response. Amber smiled, "You know it's my birthday today? That's why I'm in by birthday suit!" she laughed, then leaned in closer, "You know what I'd like for my birthday?"

Marc looked to the side were the hot young naked girl was whispering into his ear. He raised an eyebrow to the question.

Amber whispered on, hoarsely, "I want a rock hard cock up my juicy wet pussy..." Marc groaned again. "Unfortunately, I wasn't allowed to invite my boyfriend tonight, so I was going to have to go without..." She licked his cheek and grinned devilishly, "Until you came..." Her body slithered down the bound boy's until her hips hovered over his stiff member. Amber looked up, making sure Marc could see as her pink pussy lips dipped dangerously close to his red hot prick. "Of course..." she added, "when my boyfriend finds out, he'll be very very very upset..."

Marc made a meek groan that was a mix of desire and disappointment.

"I could just let you go and we can forget the whole matter, or we could have some fun and deal with the consequences. Your choice," Amber said casually. "All you have to do is tell me who put you up to spying on us!"
