More teasing.

Pushing you up against the boulders, Kristi sandwiches your leg between hers and starts breathing heavily in your ear. You're barely aware of her hand creeping up your chest while she starts nibbling on your ear lobe. "You did very well to not fall for my trap," she coos, using her knee to coax blood into your cock. "I think you deserve a bit of a reward." You close your eyes and swallow as you feel her grip onto your chest and her lips start suckling on your neck.

When she's got you half-hard, she whips your cock out of your shorts, traps it in the crook of her knee and starts to flex. It's an odd sensation to say the least, but still strangely pleasantly stimulating with her now sucking on one of your nipples as well. You groan quietly and grab her ass cheek in appreciation. But there's a nagging feeling in the back of your head that you have to address. "May I cum this time? Please?"

"You want to cum? How about no?" she purrs, releasing your cock and stepping back down. You begin to sigh in disappointment, but she turns slightly, squeezes your cock between her thighs and starts to rub along it, making your groins meet. You groan again before she takes your cheeks in her hands and forces you to look at her. "Do you want to know why you're not allowed to cum?"

Unable to look away, you nod.

Kristi starts moving a little faster, the sunscreen mixing with your pre-cum, making her thighs slick and sticky at the same time, and a barely audible thumping noise against the boulder. "Because I want you to give me the biggest, thickest load you've ever had later tonight," she gasps. "I want all that hot, sticky, white juice you can make when I milk it out with my dripping, tight pussy. Do you want that? Or would you rather cum here and now with my thighs, and waste all of my hard work?"
