I was slowly building up speed. We were in a car, in a public park and it was still daylight. I figured a quickie, in this case, would be prudent. Jus... as I was developing a good rhythm and exquisite friction, my knee slipped off the center hump to the floor. I slid all of the way out of her and Kelly’s moan turned into more of a whine. I quickly repositioned myself and slid back home. I was thrusting into her sweet sex. The sensations were wonderful. Kelly began to whimper and squeak, her. “Well it feels a bit lighter.” he said, bouncing it slightly in his hands to feel the weight.“I swapped out the heavier old power supply!” Dana grinned.“The Ashanath power generators can pump out a lot more power in far smaller devices.

Together, we walked to the far back of the room, where a small bar sat against the back wall. It was unattended, since all the drinks were free anyway, and the only waitress was busy moving along the guests, handing out new drinks and refilling old ones.She gingerly sat down on a bar stool at the side and I took the one next to her, turning my front towards her so all the other guests would be in my back.

When she opened them, they looked worried. But she slowly nodded.The waiter arrived with the wine, and the appetizers, but didn't linger or make me taste the wine before he left. He'd earned that tip right then. Anna took her wine glass and emptied it."Whoa ... easy there. I want you sober for this." I said. She flipped me off, which made me very happy."Ok, ok. I'll stay sober. I just needed.
