She accepts Ben's challenge

Dr. Francis' eyes bored in Ben's and he just smiled at her with supreme confidence as she said to him, "All right I will take your stupid bet, but you are going to regret it when I make you cry for release." She gripped his cock as she said this, giving it a hard painful squeeze.

Ben just looked at her and said, "Yeah, keep going I like it rough," and then he growled at her in mock lust. "Then he added if I make nine you have to take it up the ass."

She just laughed at him, "Sure, I'll fuck a donkey if you want. No man can ejaculate nine times in one afternoon. Now what kind of porn do you want to watch?"

"I don't need any porn, just the thought of fucking your smug face, and making you scream as my cock rips up your asshole is enough inspiration for me," Ben answered.

With that he pulled down his pants and took a nice glob of lubricant on his hand and started to jack off for them. "Remember to let us know before you reach orgasm, so Dr. Francis can capture all of your ejaculate for proper measurement."

"Yeah, I got it Ben grunted back his cock swelling to full erection as he pumped it rapidly. He focused on Sherry Francis staring at the swell of her tits below her lab coat, dreaming of how good her tits must look. He wondered if her nipples were pink, or more a dark color, he could just feel the stiff nubs in his mouth as he felt his first orgasm coming on. "Get ready," he groaned has he got ready to erupt. Sherry handed him a test tube and he pumped a nice respectable load into it.

Ben could feel his cock swelling as he finished climaxing, and his cock was twitching as Sherry called out the measurement to Dr. Moab, "Six and five eighths inches."

"That’s bigger than when he started Dr. Francis," Dr. Moab reminded her.

"Yeah, I know. It doesn't mean anything though, he is just a little more excited than before that's all."

Ben just smiled and started pumping his cock again; dreaming of what he was going to do to Sherry Francis's lovely body. Sherry just gave him an icy stare and as he erupted again got ready to measure him. "Damn, she said he is seven and a quarter inches now. His is getting bigger."

Ben started jacking again and began to taunt her, "Yeah you might want to stretch your ass a little cause when I go nine climaxes I'm going to have a foot of hard cock to ram up your bung hole.

She measured him again after his third eruption. "God damn he is eight inches now, how is he doing this," she asked in frustration.

Who cares Dr. Moab answered, "This is amazing. I've never heard of anything like this in the journals. Keep him going. Get me a girth measurement too, damn I should have thought of this before; I wonder if he is getting thicker as well as longer?"

Ben just kept jacking his cock feeling his fourth discharge not too far off. He was into hyper mode now and was ready to do some serious fucking. He moaned for another tube and ejaculated long strings of jisim into the test tube his eyes locked onto the hate filled eyes of Dr. Sherry Francis.

She measured him again, eight and three quarter's inches long, seven inches around. She stood back and waited for him to start again. Ben laughed and said, "That was four Doc, strip and start masturbating for me. I want to see the cunt that is going to be fucking my cock in a little while."

"Surely you don't expect me to keep that ridiculous wager."

"Well then surely you don't expect me to keep up the show for you either," said Ben back to her in a sarcastic voice.
