Part 1.
That holiday weekend everything changed when I was invited to a barbecue at my son's pool. When I arrived, my son greeted me at the door wearing swimming trunks.
"Hi Dad. Come in, make yourself comfortable and then come join me outside by the pool," Scott giggled.
After taking off my sandals and removing my shirt and trousers, I slipped into my swim trunks and followed Scott outside to the pool to meet Morgan and Allie. I was surprised to see them topless, lying face down on the loungers by the pool. As I approached them, they stood up.
"Hello, Dad. It's good to see you again," said Morgan.
"Hello, Grandpa," beamed Allie, looking into my eyes.
“Hi girls, nice to see you, I mean, to bring you up to date,” I blurted out.
My cock instantly twitched and hardened as I tried not to stare at Morgan's small, perky tits with their hard nipples and Allie's plump, young breasts. When Morgan came to me, wrapped her arms around my neck, and kissed me in greeting, she pressed her breasts and hard nipples against my bare chest.
When Allie stood on her tiptoes and kissed me, I felt her small breasts and nipples against my chest. Then she wrapped her arms around my waist, pulled me close, and began to...
Rubbing my pussy, covered by my bikini bottoms, against the bulge in my swim trunks.
I pushed her away and said, "Behave yourself, young lady."
"Dad, you're not embarrassed to see our breasts, are you?" "I hope you like them?" giggled Morgan.
When Scott asked, "Do you want a beer, Dad?"
“Yes, I do,” I replied.
“Is that a ‘Yes, I like your breasts’ or a ‘Yes, I want a beer’?” Morgan giggled.
“Both,” I stammered, glad that she couldn’t see my hard, throbbing cock.
When Scott came back with a beer and handed me one, I took a sip but spilled the beer everywhere when I heard Allie giggle: "Grandpa has a boner."
While I desperately tried to hide my hard penis in my swim trunks with my hands, Morgan giggled: "Dad, don't be ashamed." Allie has seen her father's hard penis often enough.
When Allie reached out and started squeezing my hard bulge in my swim trunks, she giggled: "Grandpa has a big penis."
I pushed her away again and jumped into the pool, but my granddaughter jumped in after me. As I desperately tried to swim away from Allie, her mother, Morgan, jumped into the pool and grabbed me from behind. She held me tight and prevented me from swimming away from my granddaughter, allowing her daughter to grab my penis through my swim trunks.
I was standing in the pool, Morgan was holding me tight, and Allie was pushing my penis through my swim trunks. I closed my eyes in disbelief and desperately tried to stop my penis from getting hard. But then I opened my eyes wide as Allie pulled down my swim trunks, put her hand around my hard, throbbing penis, and began to stroke it.
"Mom, look how big Grandpa's penis is?" giggled Allie.
“Mom, I made Grandpa come just like I made Dad,” giggled Allie.
I couldn't believe what I had just heard. That my eleven-year-old granddaughter was masturbating her father.
"Let's all get out of the pool," Scott said.
After climbing out of the pool, I sat down on a sun lounger. Morgan sat down next to me, put her arm around me, and asked, "Dad, are you okay?"
“I am completely overwhelmed,” I replied.
When my son sat down on the other sun lounger with Allie, she leaned forward, took her father's hard, throbbing penis in her mouth and began to move her mouth up and down his shaft.
“I’m so confused, I don’t understand what’s going on,” I confessed.
As I watched my son's cock explode and my little granddaughter swallow her father's hot, incestuous sperm, my soft, exhausted penis began to twitch and harden again.
Morgan giggled: "Dad, we want you to join in."
"Are you saying that I'm having sex with Allie with you?" I gasped in disbelief.
“Yes, I want to fuck, and Allie wants you to fuck her,” she giggled. Morgan put her hand around my penis and stroked it.
When my penis was rock hard again, Morgan leaned forward, took my hard, throbbing penis in her mouth, and began moving her mouth up and down my shaft. I placed my hand on the back of her head and guided her mouth up and down my penis.
"I'll be right there," I squeaked.
Morgan took my entire cock deep into her mouth as I exploded, my hot cum spurting into her mouth. After I finished and my cock went limp and soft again, Morgan lifted her mouth from my cock and kissed her little daughter, squirting some of my cum from her mouth into her daughter's mouth.
"I like the taste of grandpa's sperm," giggled Allie.
I looked at my son in disbelief and asked, "Why?"
"Because Allie asked us," Scott replied.
"I want you to fuck me, Grandpa," Allie giggled, coming over and sitting down opposite me on my lap.
With my soft cock between her legs, rubbing against her hairless young pussy, Allie began to rub her pussy against my exhausted cock. Then she reached down and lifted my hands to her young, swollen breasts. As I cupped and squeezed her breasts, Allie wrapped her arms around my neck, leaned forward, and kissed me passionately, pushing her tongue into my mouth.
As Allie and I finished our kiss, I looked at her parents. They were sitting together, snuggled up close, watching me with Allie. I wrapped my arms around my little granddaughter, pulled her close, and kissed her forehead.
"Is anyone hungry?" Scott asked.
"I want to fuck grandpa?" Allie shrieked.
“Your grandpa needs to recover, darling. He’s going to fuck you after we’ve all eaten,” Morgan giggled.
While Scott heated the grill, I sat with Allie on my lap. When Morgan took out the meat and sat down next to us, I asked, "How long has this been going on?"
"Do you want to know how long Allie's father has been fucking her?" Morgan giggled.
“Yes, that’s exactly what I’m asking,” I replied.
"Since Allie was nine," Morgan said.
I sat there for fifteen minutes, thunderstruck, unable to believe that my little granddaughter had been fucking her father since she was nine years old.
"The grill is almost ready, why don't you three go and wash yourselves in the pool?" asked Scott.
When Morgan, Allie, and I jumped into the pool, we hugged and groped each other in a group embrace. I fingered Morgan's pussy with three fingers. Then I slipped a finger into Allie's pussy and started fingering her. She and her mother took turns stroking and caressing my cock until it was hard again.
"Come and eat something," Scott called.
As we got out of the pool, Morgan giggled: "After we've eaten something, I want to watch you fuck, Allie, Dad."
I was sitting at the table, eating a burger, and couldn't take my eyes off my young granddaughter. When she saw me, she spread her knees and ran her finger over her young vulva. She pushed her finger inside her young
She opened her pussy and started fingering herself. Then she pulled her finger out of her wet pussy and put it in her mouth. My cock throbbed as I continued to stare at Allie's open labia and watch her suck.
After we had finished eating, Morgan giggled: "Dad, lie down on the sun lounger."
As I lay down on the sun lounger, Morgan held my hard cock skyward and let her little daughter straddle my lap and lower herself onto my cock. Her mother guided my cock into her daughter's cunt, Allie's cunt sliding completely into my shaft, and she sat there, impaled on my cock. With a radiant smile on her face and sparkling blue eyes, she looked up at me. She began to bounce up and down on my cock as if she had been fucking her whole young life.
