Endless cum

"Well, the surgeon said I'd have a bottomless supply of cum. I should be able to orgasm as often as I want. Let's see if she was right, Betty."

"You're disgusting," Betty said, but she continued to stroke me, the sticky strands of my cum adding a delicious lubricant to her motions.

Hmm, interesting, I thought. I felt aroused, but I could tell that her limp handjob wasn't going to cut it this time. I wondered if my penis would communicate that to her or if I'd have to tell her myself.

Spectacularly, the enhancement seemed to work precisely as advertised. Betty's body could tell that my penis needed more stimulation, so she grabbed me with both hands and started working my shaft furiously. Apparently, she needed to be able to see what she was doing, so she opened her eyes to get a better look, her frown further deepening.

I came again, shooting my load all over her arms and further adding to the mess I had made.

"Keep going," I said, wanting to see what would happen next.

Betty was literally crying by now, but she was working hard at pumping my cum-soaked penis. Again, I could feel that the stimulation she was offering wouldn't be enough, and I waited for the pheromones to kick in.

And kick in they did! Betty bent over me and started licking my balls, tenderly at first and then with more ****, as she continued to work my long shaft with both hands. The warmth of her mouth on my testicles was delightful, and a few minutes later, I came again, my load shooting all over her full red hair.

"More!" I shouted, and Betty whimpered.

"Please, Martin, let me go. Put it away!" she begged.

"One more ejaculation, and I'll let you off the hook, Betty. Just make sure it's a good one."

I saw her eyeing my large, sticky penis and considering how to proceed. I'd have welcomed any additional stimulation - her mouth, her boobs, her legs or pussy. I wondered what her body would tell me I needed.
