Idea discussion while fucking.

“Come here Kimmie,” Dr Duggan said as he stripped off. I stood up and walked towards him as he sat down naked and patted his lap. His cock was shorter but quite thick. “Now I do believe that I am the one who writes your scripts for the pill.” He grunted as I mounted him, his cock was thicker than Dad’s but no so much as to be trouble. “And I don’t believe I have given you any scripts for a while.”

“No sir,” I said as I started to ride him.

“Frank, let’s start with the hormones, could you grab the tablets and needles from the bag?” Duggan asked him. As dad pulled some stuff from the doctor’s bag I looked at it, one needle seemed quite large, another was not, then there were two bottles of tablets.

Duggan took the large needle from my father, “This is a once a week injection, it will stimulate breast growth and hormone production, increasing your fertility and in rare cases starting lactation without pregnancy.” I moaned as he unceremoniously shoved the needle into my tit and squeezed it home. “This,” he said putting the big needle down and picking up the smaller needle, “is a daily, three weeks on, one week off, fertility enhancer,” He injected it into the other breast.

As he withdrew the needle I started bouncing more, then I felt Dad close behind me. “The tablets,” Duggan continued, “are a slow-release aphrodisiac, which should increase your libido constantly and some immunosuppressants so that, in the event, the group want to modify you, you won’t reject the surgery.”

Dad started to feed his long cock into my arsehole, making me feel so stretched between the thick cocks. After he managed to get a couple of inches into me he asked Duggan again, “So what kind of modification do you think would be nice?”

“Go slow Frank, I can feel you pushing inside her and it’s making her feel particularly tight, I don’t want to cum yet. My family doctor said. “Well, I would love to do another breast graft, Welcombe looked so nice with the four tits, maybe we could one-up it and give Kimmie here six.” They were slowly fucking me while they talked, almost acting as if I was not even there. “I have also been looking, and I think we could do a horn graft, one on each side of the head just above her ears so we have handlebars to hold onto.”

“I’ve already found she can deepthroat,” Dad said, “But we could open her throat up more, make it easier.” I shuddered as I came over Duggan, “Oh and you spoke about that trachea valve so she could deepthroat and still be able to breathe.”

Duggan groaned, “Yeah but **** her is part of the fun with deepthroating, maybe we can do some extra implants, you know, silicone ridges in the lining of her throat or cunt to give us extra sensation.”

That did it, I came hard and my vision blurred as I screamed in ecstasy.
