The shadow of someone passed over us and I slowed, biting my lip, but Dan encouraged me, tweaking my nipple, making me sigh and gasp. I wanted to tuck my hands between my legs, to rock against my palm, but I didn't dare. My clit was throbbing as I nudged myself, bit by agonizing bit, toward orgasm. My thighs were flexed so tightly that, three days later, I would still feel the soreness in my muscles — but I didn't notice it then. His cock strained against his jeans — I could actually feel it pulsing through the denim — and that turned me on even more. I longed to take him into my mouth, to make him come, too…

But he was focused on me, whispering things I could barely hear, "That's it, good girl, do it for me, come on, baby, that's so good, you're so beautiful, don't stop, don't stop…" I couldn't have stopped if I wanted to. The delicious, winding spiral that had been stretching between he and I all weekend was pulled to its maximum, taut and trembling with such force that my thighs, my breath, my whole being shook with it. I knew it was going to snap back, and the sensation would send me into orbit.

"Oh god…" I whispered it. I think I whispered.

My hips moved faster now, my thighs squeezed together so tight they hurt, my little clit rubbing over the seam of my jeans again and again and again. Dan moved his hand surreptitiously to my other breast, shifting his weight, his thumb touching my nipple and that did it — the feeling reached its limit and my whole body stiffened with pleasure and I quivered in his lap, burying my face against the hard, heated length of his shaft as I came, feeling surge after surge shuddering through me.

We didn't talk afterward. He stroked my hair as my body began to relax and the flush in my cheeks began to fade. I didn't open my eyes for a long time, too afraid of what — or who — I might see around us. Later, Dan said he didn't think anyone had noticed, and considering how busy it was, he was probably right.
