You can't wait, get to fucking right away.

I suddenly feel like I don't want to wait anymore, there an itch, no in fact it's more like an ache and hunger that can't be sated. But all of my primal instincts are pointing to one thing and that is. _"PUT THAT COCK IN ME" _I say suddenly to Leo as I push his face away from eating my pussy. He immediately complies, readying his well endowed cock that doesn't seem to fit his position, but at this point all I could think of was how big it was.

He prodded with the tip of his dick on my entrance, almost like he was teasing. I felt a warm sensation kissing my lips and walls, I can feel it slowly parting as he pushes his head in steadily. Which caused my body to shudder followed by a loud moan that lasted the same amount of time he penetrated me to the base. "Unhhhhhhhh...haaaaaaah..ahhhhhh" I started to moan more and more and that was just one stroke.

It felt like I was being split apart in 2 as Leo penetrated me. My unused, fresh and wet inner walls clamping down on his cock like it was hanging on to dear life. I knew my pussy was going to be tight, but this was crazy. Another stroke sent me to nirvana as my moans grew more intense, my body arching upwards and my head shooting up as the tip of his cock seemed to have kissed my womb's entrance, giving my cervix a little greeting.

"Ahnn...don't stop...unhhh..FUCK!" I managed to say in between moans as Leo quickened the pace. I was laying on the table as he fucked me harder and faster (like this)

Every thrust sent Leo's cock deeper and deeper, or at least that's what my mind was thinking. Being a scientist I could comprehend what was going on inside, but only to a certain degree as being fucked like this made it hard to concentrate. But my analysis so far has been that every stroke seems to crush down on my cervix, almost as if his cock is knocking on it for permission to enter, in which I think at this point could be possible if he keeps this up as he keeps fucking me like this.

*Within Eli's body, her ovaries managed to produce 4 eggs in one spurt. They are slowly traveling down her tubes as the nano machines assist in the formation of her uterus walls in the case implantation happens. Her cervix is being pounded harder and harder but the nano machines had altered Eli's body to the point where certain impossible penetrations were ...well possible*

As Leo pumped into Eli's pussy, she felt something building within her, a sensation that she guessed was an orgasm. Along with that, she felt Leo's cock pulsing harder with every grunt and thrust. She knew "He's going to plant his seed inside my womb isn't he....this could be troublesome if I get pregnant, I'll never know what-!!!!!!!"

before Eli could finish her thoughts, the last stroke by Leo had sort of penetrated her cervix. Her second hole now clung on to his cock like a second cock sleeve. _"Shit, he's driving me ahn.... ...hnnngg..NUTS" _I thought as my body arched from the pleasure of being penetrated once more, at this point I can feel my reason's slipping. Another thought invaded my mind and it was "I wanted to get pregnant, I WANT HIS BABIES" was all my head could think off.

Knowing well that I'd regret it, my brain and body could not lie, I was going to get addicted to this sensation. At this point, my legs had locked his back in a missionary position, my head is rocked back and my tongue stocked out. My eyes were rolling upwards into whites as I feel myself being fucked silly by Leo's dick like this.

With one final thrust and pulse from his cock, a hot sensation filled me. His warm spunk was being injected deep into my womb, and it seems that he has been saving up lots of it. It was unreal as I felt an unnatural amount of cum being pumped into my womb, I feel almost full. It was like my womb was going to break as I felt a small ache, but what followed was my first female orgasm that sent me over the edge once more. I couldn't think of anything else as he came in me, the only thing I did was pull him closer with my legs and making sure that he plugged my womb and to not let a drop of sperm escape from my cervix.

*Inside her womb, all the eggs that seemed to be swimming around was bombarded with sperms all looking to fertilize it, soon all of them were fertilized and started it's division and moving towards her uterus lining in order to implant itself*

Outside, Leo finally pulls out and as he does so, her holes immediately gushed out a fast stream of cum, Leo flopped to the floor, catching his breath as he laid down.

I on the other hand was still fueled by ecstasy and pleasure. I tried to get up as I felt the cum running down and leaking from my womb, no doubt because the immense amount being pumped into me.

Then suddenly I felt something in my belly...no more precisely my womb, something had just attached to my uterus lining as the nano machines just sent information to my brain. I AM PREGNANT.
