On her back

I am about to cum into Sophia's sweet ass, but I determine to cum into someone more familiar. My sister, Cindy, was probably a virgin and would be the perfect receptacle. Never mind, I thought, as I spotted her being double-teamed by both my grandfathers, Arnold and Joe. Joe Doe screamed out in ecstasy as he came into my sister, possibly robbing me of a future **** child. I pull out and almost immediately cum in large globules all over Aunt Sophia's back, some even having deposited in her ass and leaking down and out.

More than a regular human man can cum, I look well at the large pools of semen on her back, ass and the surrounding patio. She looks back and smiles, "Should I get up?" I wave my head no, and she stays in place.

I look curiously at the line leaking from her ass and into her pussy, before leaking onto the ground. She probably can't have kids, but if she could, would that be enough? I reach into her pussy, and massage some more of my spunk into there, as she gently moans. "Hazel," I call out to the nearby cousin as she is performing hand jobs on her father and another cousin. She quickly let's go, to their disappointment, and stands by my side.

"Yes, sir?" she asks, to my bemusement.

"Do you think if I put this fresh cum in you, that you'll get pregnant?" I took a scoop off of Sophia's back and felt a tingly sensation, as if the sperm were especially hyperactive.

"Probably. Spermatozoa from a Phalarsenasthenian is highly motile and considered to be the most fertile reproductive transmitters in all known science. Most sperm last a few minutes in the wild, but yours could last several hours. Scientists have actually ran many tests and the results baffle even the top biologists and..."

I told her to shut up and push the sperm into her pussy with my right hand. She winces at the coldness and stands there, non-reactive, as I massage it in. I stare at her face long enough until she fakes a smile, not seeming to notice as I rubbed her clit while placing my splooge in there.

I leave her to go back to her father as I walk around our small pool. Mom is enjoying herself with her brother-in-law. Newly impregnated Alex is now making out with her mother Diane, as I reached the diving board where Cindy is being fucked by the two old men.

I glance between Cindy's nethers to see the remains of her virginity, forgotten by all as they clearly enjoy themselves. "Still at it, Grandpa Joe?" I ask, slapping my paternal grandfather on the back.

"Viagra, my boy. It's a blessing and a curse." He said, as he begins cumming into Cindy a second time.

"I hear that," all four of us laugh, even though I will never need viagra in my current state. I enjoy watching the family orgy, the Does and Smiths united as one large crew, linked together in the closest way imaginable. Everyone was here. Everyone, but...

"Well, well, well... this is my kind of party!" came the gruff voice from behind me. I looked at the slightly disheveled face of the grifter that I hadn't seen since I was very young, and then only in passing. "And we have to thank you, my boy, for the reunion!" He smiles, a set of misshapen teeth surrounding one gold-capped one as I spin and catort myself in surprise.

"Dad?!"

"In the flesh. Although it appears I am... overdressed." He smiled wider as everyone nearby looked on in surprise.
