The sharp heel of her shoe dug into my back as she pulled my face toward her. Her thigh lifted her skirt and I was shocked by the sight of her expo...ed pussy. A sea of thick hair was parted by two wrinkled folds. I don’t know if she removed her panties while I was waiting in her office or if she always walked abound in just stockings and a garter belt, but the site of her naked twat inches from my face made me pause. She pulled harder with her thigh, digging the heel. 'I kinda wanted to be left alone and was about to tell him bluntly when I noticed his expression - he looked almost concerned. I eased up a bit.'No thanks I'm fine just reading today.' I said.In return, he shrugged and smiled, walking off with the ball. I watched him walk off and noticed how defined he was around the face and as soon as I began to get absorbed into my book again, I was surprised by Josh once more who came back, this time without a ball.'How come you're not playing?' I asked.'Oh. The doctors hands were shaking again as he squirted a jet of fluid out of the tip of the hypodermic needle. I could sense his excitement and arousal. I don’t think he realized how excited I was feeling as well. He unfastened the waist button on Sarah’s tight shorts and pulled the zip down. He got me help roll her onto her side . She didn’t react or speak as pulled her panties down to expose the top of her left buttock. He wiped a small swab on her smooth skin and jabbed the needle in. Sam had half the dildo inside his bottom he pulled his knees up and began sliding it out then in slowly he asked me to squeeze some more gel on the dildo as he used it. I was surprised to find my hands shaking as I squirted the gel on the plastic cock. Sam had now almost the entire 8inch dildo in his virginal bottom, as he began fucking himself I was rubbing my erect cock over my trousers. Suddenly I stood and stripped off my trousers and underwear freeing my modest 5 inch cock and moved.
