Instinctively, she began pushing up to increase the delicious pressure. He responded by grinding his cock against her smooth skin. They had been kissi...g with a fierce, almost painful intensity. But now she changed the pace. Putting her hands on the sides of his head, she gently inserted her tongue between his lips and started moving it around like a languid snake, making slow, sensuous oral love to his mouth. They finally broke the kiss and in silence looked at one another. Both knew it was now. He slowly licked her nose and eyebrows. He reached down between her legs and pulled her skirt up as far as it would come and then slid his hand up between her tight legs. The straps forced her legs together and he didn't have time to loosen it.He laughed as he quit fondling her and pushed her cart out of the room into the lab where Luthor was waiting. He would have loved to have more time to play with her but Luthor was waiting and you didn't want to piss Luthor off too many times in one day.. Unfortunately, he remembered that I’d told him he could resume his abuse of my libido during dessert, and he did, setting the egg throbbing again. Surprising myself, I soon came hard, and I think my fingers may have left dents in the table where I was gripping it so tight, attempting to be quiet and not writhe around. I didn’t entirely succeed, but mostly, and I also didn’t much care by then.He continued to let it throb inside of me, and by the time we left, I was a quivering mass of nerve. She got back her smile, and tugged briefly at my hand to draw me upstairs. Once up the stairs, she led me down a hallway to a door, apologizing, "It's one bathroom for three girls, so sorry for the mess."I couldn't really tell. All the bathroom lights were on the same circuit as the sink outlet she'd blown so those bulbs were dark. I touched her shoulder lightly. "A flashlight would be really handy right about now."Ellen jumped to serve me, running back down the staircase. And then she was gone.
