Yes

He nodded his head, “It’s not to fill you with precum though.” He explained his cock pulsing again, “I just don’t know how much I could resist if I was fully hard.”

I moaned and ground into him a little more “I like hearing that you might not be able to resist.” I said I was about to continue but felt his cock throb again and used the opportunity to sink down just a little more, his cockhead popped into me, my lips sitting at the curve under his head. “I need a bit of a rest though, sitting up like this is hard.” I said.

His cock throbbed filling me a little more, “You want me on top?” he asked.

I shook my head before letting my legs relax, sinking onto his cock, his eyes rolled as I sank down, my cunt well lubed by his copious precum, until I was almost balls deep. Then I felt resistance as he bottomed out in me. “My God Dad, and you’re not fully hard.” I felt another pulse. I lent forward and lay on him his cock throbbing in my cunt stretching me with each slight movement. Every once in a while I felt a warm rush as he continued to throb with arousal and add more precum to my already drenched cunt.

I whispered into his ear, “I have felt at least eight strong pulses of your precum fill me since I mounted you.” He pulsed again, and I moaned. “How much before you knock me up?”

There was another pulse as he signed, “Are you really fertile?” He asked.

“If I said no would you fuck me?” He nodded his head, “Even though you would know it was a lie?” His cock pulsed again and he nodded. “So you really want to fuck your fertile little girl? But you want to have justification when you knock her up”

I felt his cock swell and lengthen as well as feeling yet another hot gush. “So Dad? Are you fully hard yet?” I asked him again.

As if strained her said, “If I say no?”

I pulled myself along his body and slid myself back down slowly fucking his mammoth cock, “I think I would need to take more drastic measures.” I moaned as I repeated the process. “All you have to do,” I sighed through my motions, “to not knock your fertile daughter up,” He grunted and I felt another hot spurt, this time more significant, “is get fully hard.”

I rocked back and forth fucking his cock for quite a few minutes both of us breathing heavily almost every motion I could feel hot gouts flood me. “Kimmie,” Dad groaned after a little while.

“Yes Dad.” I moaned speeding up.

“If I was to cum in you would it make me a bad father?” I felt him shudder again, I could tell he was trying to hold back.

“Cum in me Daddy, cum in your fertile little girl.” I begged him, I heard him groan and then started to feel him filling me, hot cum filling my cunt, “Yes, Daddy, help my belly and tits grow.” For the first time he thrust into me, pushing against my cervix he shot his cum against my fertile entrance. I came with him in a long shuddering embrace of my father as he filled me, there was so much but he was so thick he stopped most of it flowing out of me. After several moments I pushed myself up slightly and looked him straight in the eyes, “How much of that were you fully hard for?” I asked him honestly.

He gave a short laugh, “Pretty much all of it, but it was part of the game, like you being fertile.” He said.

I gave a laugh back, “I am fertile Dad.” I said. I hadn’t finished my words when I heard another groan escape him and felt him cum in me again.
