With Zack in the cabin

"Oh, god..." Zack found himself thinking, while feeling like his brain was swimming in syrup, and his eyes kept following every fine line and curve of Heather's sensual body - all the way from the back of her neck to tips of her lustrous brown hair, where it was cut not far above the small of her back, and then further down to her rounded buttocks and slender long legs.

Most of all he couldn't keep from staring at her crotch however, which was clearly shaved clean of any pubic hair, and currently just barely visible under the tiny front of her thong. And he could still see her fingers as they continued working her ever closer to the inevitable climax - having picked up in both pace and persistence since the time he arrived.

"Nnnnuuh...!" He could hear her groaning softly into pillow, and watched as both her feet and bottom started rising slightly into the air. Soon her calves were touching the back of her thighs - her heels almost resting against her ass -, and her back swaying low while her buttocks pushed up to reveal even more of what was hidden between.

It was obvious she would come any moment now, and Zack was transfixed by the sight of her writhing body, until he suddenly realized she'd been turning her head to look out into the room. Her eyes were just barely open yet, but he could feel his heart almost stopping as they slowly gained focus and glanced right back into his face.

"Hnnn...?" She suddenly froze up - with her blue eyes growing wide for a moment in shock -, and Zack could barely breathe as he knew that he was screwed. But Heather just laid there and watched him for a couple of moments - which he felt like they lasted an for an eternity -, before giving him a lazy wink with one of her beautiful eyes.

"Are you just going to stand there...?" She asked him gently, and surprised him even further by spreading her soft thighs. The gesture and look on her face were not just inviting, but almost demanding him to somehow take advantage of the situation - no matter what way he decided to do...
