She provides what I need

She stared at me for a moment and said, “Well I don’t normally do this, but we really need your sample. If I allowed you to see my breasts would that provide sufficient stimulus to achieve an ejaculatory response.”

It took me just a moment to figure out what she was offering and when I did my cock leapt to a sudden stiffness. I stood up and my boner popped out hard and stiff as I answered her, “Yeah that will work I said to her.”

She stood up and slowly unbuttoned her lab coat. I realized that she was wearing only a bra, stockings and garters and some high heel pumps under her lab coat. Soon she stood before me in just her underwear. I was pumping my cock as I took in her perfect body. It was even sexier than I had been imagining. Her legs were long and shapely, taping from trim claves to well muscled thighs. Her black garters held up her nylons and a pair of low cut black panties covered her what I could only assume was a shaved pussy as I could see the outline of her cunt. Her huge tits stuck out in her black bra. She reached behind her and popped the clasp letting her breast swing free. Her nipples were light pink against her pale skin. Her nipples were very long and already very stiff. She reached up and pushed her big tits together and pushed them towards me so I could take in the full size of her huge boobs. I increased the speed of my jacking as she showed me her assets. Her eyes were fixed on my cock with a hungry look that I was not sure how to feel about.

It took me only a few moments to get off with the stimulating visual show she was providing. I was rapidly pumping my rock hard member, stoking the fat head just right, and I could feel my orgasm starting. I grabbed the little cup just in time to spray his first long stream of jizz into it. Dr. Jones was pulling one of her long thick nipples as I continued to pump my load into the cup moaning softly in pleasure as I ejaculated for her.

I sat down in the chair spent as the last drop of sperm hit the cup. I looked over at the topless Dr. Jones and feeling kind of cocky said, “Damn that was good. What’s next?"
