My dare #081 - The one where Brock nailed me

... pointy cock which lubricated its way forward with its precum. I screamed and cried when I realized that the beast had now conquered even my untouched uterus. And I was at least partly to blame for that.

Either the time had reached a standstill or Brock had slowed down his pace, but I found out that I was able to make sense of my situation. My eyes were wide open when I stared in disbelief at how Brock's whole cock had now fully disappeared inside of me. He had me impaled. I had never even thought that something could reach so deep into me. Any other time, I would find the picture in front of me erotic. Seeing the union of you and your lover would be sensual. But having my sister's dog fully and forcefully embedded himself into me was a picture of nightmares. I had 25+ centimeters of doggy cock inside of me, and I could feel every single vein of that dick pulsating against my walls.

Brock had recovered his balance. It was a pleasant surprise for him that he was finally able to feel himself fully inside the tight hole of the bitch. He had been nearing his limits for a while now.

He fucked me with such speed that I had hardly time to even see his cock when it withdrew and when it was plunged back in. But I felt every moment of it.

Now that he had pierced his way through my cervix, he did not leave it alone. I do not know if it was luck or instinct, but he never pulled out so far that he could not find a way to push back into my baby-making factory. The pain that I had felt after the initial penetration had subsided quickly. But life was throwing more hardships in my direction. There was more pressure building right at my vulva. I could swear that he was still becoming bigger. Panic started to creep into me again when I was about to receive the next lesson about how dogs mated. There was something ball-shaped forming at the base of his cock. I learned later that it was called "knot" and it was accurately named. The knot is supposed to tie our bodies together. But at that very moment I could ...
