When I awoke the next morning, I was laying on my back with my granddaughter's head buried in my shoulder. Then I felt something warm and very wet down between my legs and that something was moving, but Liza wasn't moving. A glance down revealed my daughter Helen with my cock slowly coming to life in her mouth.
"Helen! What are you doing?"
"What does it look like I'm doing? I'm sucking life back into my daddy's cock so I can fuck him before he gets out of bed."
"But..."
"But what?"
"I thought you were on your period. That's what you told me last night."
"I lied."
"You lied?"
"Yeah. And my plan worked out better than I could have ever expected. You fucked Liza and you fucked her royally. You got her cherry."
"Yeah, I know. I saw the blood mixed with our juices dripping onto the sheets before we went to sleep."
By this time, my cock was at full staff and Liza was wide awake. What Helen did next surprised the hell out of me. As I watched, she dipped her head between her daughter's legs and started cleaning up our dried spunk from the previous night's frolics. That got the attention of my little head and he stood up even straighter than I ever thought was possible.
"Oh, Momma, that feels so good. It's even better with Grampa's sperm in me, isn't it?"
"You know it, Sweetheart. The taste of both of you at the same time is driving me wild. I don't know who to go down on first...you or your grandfather."
"Eat me first, Momma."
"OK."
As she went down on Liza's gaping cunt, I swung in behind her upraised ass and pushed my cock into my daughter with one swift stroke, taking her somewhat by surprise. Helen lifted her head and said "Do it, John. Fuck the hell out of your daughter while she eats your sperm out of your granddaughter."
And that's exactly what I did. We all came in sequence: first Liza, then Helen, and then I blew a large hot wad of sperm deep into my daughter's cunt. After we separated, we took a shower together, washing each other's delicate places with gentle, sensuous hands and fingers. None of us orgasmed again, but we were sure clean after that shower.
***************************
Three months passed within the blink of an eye. Liza graduated from high school with honors and never looked prettier than the evening her mother and I took her out to celbrate her graduation. She planned to go to the local university in the fall. We settled into a routine around the house and the days started passing quickly.
While the sexual combinations were not endless, they did lend enough variety to keep us all satisfied. But, about that time I started noticing that Liza and Helen were both getting a little thick around the waist. At first I just put it up to eating well, but when each of them started throwing up first thing each morning, I remembered back to when Erica had first gotten pregnant with Helen...and I knew. They were both pregnant.
I had taken Helen into my bed as my wife shortly after that first glorious fuck with my granddaughter. Liza, of course, had visitation rights and made use of them almost every other night. She had promised to go back on her birth control pills, but obviously she had forgotten her promise. Helen, of course, had fully intended to get pregnant with my baby, after all, what else is a wife supposed to do.
It seemed that my cock never had a need for any pussy other than what was already under my own roof. I was in pussy heaven and loving it every moment of every day. We fucked in the mornings, after lunch, and in the evenings. Sometimes it was a twosome and sometimes a threesome. Every time was exciting and rejuvenating. I had never felt more sexually satisfied as I was during those three months.
Then came the confirmation of their pregnancies. Helen called a family meeting and we all sat down comfortably in the living room with me between the two loves of my life.
"John," my daughter started. "We have something to tell you."
I slowly glanced first at Helen and then at Liza before saying "You're both pregnant."
"Yes, but how did you know?"
"Well, my dear Helen, I've been through at least one pregnancy, haven't I? Yours. Your mother had the same symptoms you two have been having for the past couple of weeks. Morning sickness and a little bit heavy around the waist. Those are almost positive signs of pregnancy, aren't they?"
"So you knew?"
"Yeah, I knew. I didn't realize that I was going to be a father, a grandfather and a great grandfather at about the same time, but I knew. When are you two due?"
"It seems that you got Liza pregnant the night you took her cherry. She's due in late December or early January. I'm due a couple of weeks after she is." A glance at Liza showed a smile that went from ear to ear and eyes that were twinkling with delight. I could see that motherhood was going to be good to and for her. I smiled back and turned to Helen to see that same shit eating grin plastered on her face.
"We're going to have to add on to the house, I guess. Otherwise it'll get a bit tight around here. Besides now that Liza is a mom-to-be, she is going to need her own room so she can have enough space for the little one. I'll call a couple of contractors I know and get some estimates for building a couple of more rooms." I left to place the calls to the contractors and my two incestuous girls started to talk about exactly what they would need for the babies.
***************************
About a week after construction started on the additions to the house, Liza came into my bed and lay down beside me wearing nothing but a smile. Of course my cock rose to the occasion and I rolled over to face her bringing my mouth to hers and tasting her. I drew a line from her left ear to her tits with my tongue and suckled for a couple of minutes on her enlarging breasts that I knew would soon be filled with sweet, wholesome baby milk. This brought a slight gasp from Liza and she held my mouth tightly to her nipples seeming to want me to swallow her tit whole.
