It keeps him awake, and might lead to a second round

It was a bit later the same night - perhaps an hour, or just a little bit more -, and Zachary was still having trouble falling asleep. It was partially due to the young woman who'd insisted on nestling herself close to him of course, with his arms around her warm and lustful body - although their earlier activities should have worn him out as much as it'd done to her.

He still couldn't let go of the thought that some of the girls he fancied the most were sharing the same room as another guy tonight - even if this guy happened to be his own most trusted friend -, and it most certainly didn't get any better with the way which Heather had made him imagine it was one of them who'd been riding on top of him. Nor did it ease his mind that he could still hear the vague sound of excited voices coming from another nearby room in the building, which seemed to indicate that at least one of those girls was having a pretty good time with somebody else than himself...

At the same time it was a strangely arousing thought however - even as it fueled his envy -, and he found himself picturing what it'd be like to be in his friend's clothes right now, with the two hot blondes most likely getting it on together like he'd seen them at least twice the last two days. It seemed quite unlikely that even Gavin would be able and keep his hands away for this long...

"Hmm...?" The girl in his arms suddenly stirred a little, when he happened to slide his hand along her silky skin, and she turned her head back to throw him a lazy glance and a smile across her shoulder. "Hey...? You up for another already...?"

"Huh?" Zack just grunted in reply, as he came to realize that his cock too was starting to wake up again, and nestled firmly between her taut young buttocks. His breathing and heartbeat increased accordingly of course when she pushed herself back against him, and further betrayed his growing arousal.

"Well, yeah." He finally admitted, which may have been the most intelligible words he'd said since they entered this room together, and he found some true delight from the way they touched and stroked each other under the cover of the bed sheets.

"So, would you like to play a little game again?" She grinned at him softly, with that mischievous grin returning to her sparkling blue eyes again, and caused his shaft to throb even harder against her bottom as he was reminded once again of the very last part of their session together.

"Hmm...?" He managed a weak smile at her in return, while trying to push those forbidden thoughts about his own sister back out of his head again, and then kept exploring the girl's body with increased firmness and enthusiasm - as if to show her, and also himself, that he was truly there for her this time around.

"Mmm, I like that." The brunette purred as she flashed him another lustful little smile, and pushed herself back into his probing hands again. It really seemed like was game for just about anything tonight, and he could hardly keep from being enticed by that wicked look on her face and the tone to her voice - which seemed to be practically begging him for the naughtiest thing his mind would be able and come up with. "Just tell me how you want it...!"

"Hmm, sure..." Zachary returned with similar mischief to his voice, although he wasn't quite so certain of what could possibly pass for a challenge to the much more experienced young nympho in his arms. The situation did seem to call for something special though, and he could feel a smirk on his lips as he leaned in closer to her ear...
