Inside

I immediately released into Dawn's cunt. I've never come twice in such a short time frame before, yet despite that I released what can only be described as a flood of molten white lava up into the beautiful woman riding me.

I continued pumping cum into Dawn's repository for a spectacularly long time. Her pussy began to over flow and I could feel my sperm dribbling down all over my sister's hand and onto my balls. By the time I stopped cumming, my ejaculation had been accompanied with sharp jerks of my entire body and I was exhausted.

Dawn leaned forward and kissed me as the spunk in her cunt continued to leak out around my cock shaft. I kissed her back passionately, our tongues intertwined.

Then I felt my cock get pulled free of Dawn's pussy. Dawn rolled off me and collapsed on the deck.
