Blissful ignorance followed by horrified realisation

Lauren let out a sultry moan as she ran her hands over her small mounds, the nipples fully erect and pointing straight at Mark.

"Look at me baby, I'm the hottest girl in town and I'm all yours... and you're mine," she gasped out, beginning to rub herself against Mark's groin again.

Lauren became lost in her own world as she moved her hips faster and faster, completely forgetting anything more she might have hoped to do with Mark as she became lost in her own pleasure.

For his part, Mark couldn't believe what he was seeing! Lauren - THE Lauren - naked and writhing in front of him, but not at all what she'd advertised. His eyes roved up and down her body, again and again taking in the meaty thighs, the small paunch of a stomach, the puffy, clean shaven crotch and of course, those tiny tits! Perky and slightly cone shaped, with small, puffy, pink (and currently rock hard) nipples, it looked like the chest of a girl in the early stages of puberty had been transplanted onto the adult woman he'd gone through school with, without ever suspecting a thing.

It's not that he wasn't still a little turned on, Mark mused to himself. There was still a naked woman his own age grinding on him after all... but fuck did she look different! Mark was into big titted, fit girls and seeing her now, Lauren clearly wasn't his type. A grin crept on to his face as he stared at the body in front of him as Lauren continued to rub herself into a frenzy. This was one of the funniest things he'd ever seen! Wait 'till he told everyone! Mark was just wondering if he could grab his phone and get a picture to corroborate his story, when Lauren arched her her back, let out a half screamed, half gasped 'Yes', as her body shuddered and she squirted a large amount of her female juices onto his crotch.

As Lauren began to come down from her orgasm, her head began to clear and she could feel the aphrodisiac finally leaving her system. That had felt fantastic. She hadn't realised quite how much she'd needed a good cum. Lauren smiled down at Mark as he lay between her naked thighs, only to see him looking back at her with an amused grin on his face. She felt a moment of confusion; what could possibly be funny? Wait... between her NAKED thighs?? Lauren ran her hands across her legs and stomach to confirm. Oh god, she had - she'd taken off her spanks in front of Mark! He'd seen what she really looked like down there and he found it funny. She frantically looked around for the spanks so she could cover up again, even if the damage was now done. There they were, right next to... her bra. Oh god.

Wrapping her arms around her bare, tiny chest, Lauren looked down at Mark again in horror, only to realise he was now openly chuckling.

"Well Lauren, I've definitely seen a lot more of you than I expected tonight - or should I say a lot less!"

Mark laughed at his own joke, as Lauren sat there with her lip quivering.

"I mean, I know all girls have their secrets but damn! Everything's just so... well, not what I expected," he continued.

"P-please... I... please. D-don't tell anyone ab-about this... about me," Lauren stammered out.

"Oh, I don't think it's me you should be worrying about," Mark replied, still grinning, as the car door behind Lauren was wrenched open.
