Stephen Hawking sat in his chair, motionless, working on the new formulae for the calculations of the gravitational pull of the many planets in the most recently discovered galaxy, when his nurse came in to his office. She walked right up to him, her low-cut top almost pressing up against the side of his head.
"I need to take your blood, sir. I hope you don't mind…" she said, quietly.
He noticed how succulent her breasts looked today. They were practically popping out of her shirt. He felt something rise in his pants, but she didn't notice.
"Go ahead, I could use a break." His robotic voice said.
She leaned in even closer, tying his arm with a tourniquet, her chest pressing against his face…
"Oh, I'm almost done… Just a little more…" she spoke, almost sensually. "There, got all the liquid I needed out of you." she finished, winking.
He couldn't find words as he watched her leave the room, her luscious legs clearly seen up until a few inches from the back of her ass. He watched her hips sway from side to side, until she left the room, closing the door as she did.
He couldn't quantify, with all his math and science skills, how hard he wanted to ram her sweet ass with his hard dick.
It was just unfortunate that he couldn't move.
