Knot.

As you try to grab his cock to keep him from trying to shove the knot in, your hand keeps loosing grip with how wet it was. You didn't realize how wet you had gotten.

You weren't going to last long as you try one last time to stop him as he seems to get **** on getting it in. He bites your shoulder, not drawing blood, but as a warning .

You drop your hand quickly as the next thrusts were harder as he tests what he could do. Each thrust pushes more of the knot inside before there was an audible pop as he pushes it in you

You scream out as your stretched even further, and the tip of his cock pushes into your womb. You cum hard around his cock and knot, your walls milking his cock as you feel a sudden warmth filling your insides as he begins to cum straight into your womb.

You collapse and rest the top part of your body on the cool grass. Your hand moving over your belly, swearing you could feel it starting to bulge with how much cum he was putting inside of you. You would be lucky if you didn't get pregnant from this.
