Ben looked over at the sexy, topless doctor and reminded her, “Yank our nipples for me Doc. I am ready to blow my load again.”
Dr. Williams gripped her long nipples with her glove covered fingers and began twisting and rubbing them as she reminded him, “Remember to ejaculate in the test tube. I want to capture the full amount of your ejaculate to measure how much your production decreases with every ejaculation.”
Ben moaned as he watched her playing with her nipples; nothing turned him on more than watching a woman play with her tits. Miss Williams was doing a nice job, plucking and pulling her thick nipples, making them swell to full erection as Ben watched. Ben kept pumping his cock quickly and he could feel his orgasm beginning as he grabbed the tube to ejaculate his 5th load of sperm into it.
He told her, “I will cum even more as things go along. I always come more on the last one than the first one." True to his word he brought himself off and pumped his load into the test tube, almost filling it to the top. His cock was a long, thick purple hose in his hands. Long veins pulsed up and down its length, and the fat apple sized head dripped a steady stream of jizz from its piss hole. It had swelled even further as he neared ejaculation and the long streams of cum that shot out of it were thick and white. Miss Williams had never seen a human male ejaculate such a massive amount. Then Ben said, “You had better get a bigger container or I am going to overflow it on the next one."
As Miss Williams watched he kept pumping his erection and it swelled even bigger before her eyes. Miss Williams was very horny herself as pulling on her sensitive nipples while watching Ben pump his horse cock created a level of sexual excitement that she had not know in some time. She knew she had to work at it to keep her sexual desire from compromising her results. |
