"Why don't I stay with Grandpa?"

I never thought that such a simple, innocuous question would set up a chain of events that would completely change my life.

My name is Jenna and I was 21 years old. It was the summer after my sophomore year of college and I was spending it at home with my mother Katie. Juniors were no longer given on-campus housing, so we were discussing possible options. My grandfather lived in the same city where I went to school, so I figured I might be able to save some money by staying with him.

So I offhandedly asked that fateful question. "Why don't I stay with Grandpa?"

"NO!" my mother snapped. "No!"

I was startled. Why was my mother so frightened by the prospect. My mother and I had always had a good relationship with Grandpa. I'd always seen him as a loving, typical grandfather.

"Mom, what's wrong?" I asked. "Why shouldn't I stay with Grandpa? We could probably get a good money on the rent."

My voice faded away as I saw the pain and shame on her face. "Do you really want to know?" she asked.

I wasn't sure that I did, but I nodded.

"Okay, but promise me you won't mention this to anyone, especially not your grandfather."

"O-okay..."

Mom took a deep breath. "You know my mother died when I was a teenager. I took over as the mom of the household, helping your grandfather do the housework, take care of my siblings, and everything else. I became like a wife to him. Then, when I was about your age, he said he wanted me to become even more like a wife to him."

She paused again, gathering her thoughts. "He said he was in love with me. Romantically. Incestuously. His own daughter!"

I couldn't believe what I was hearing. "Y-you mean he...molested you?"

"No," my mother answered. "He never touched me. He respected my rejection and never brought it up again. But still, it was traumatic. It sort of tainted everything. Every hug, every kiss. I had to wonder what sick thoughts he was having whenever we touched.

"Please don't tell him you know this," Mom continued. "We both worked hard to get past that and heal our relationship. It'll never be perfect, but it's better."

That was the end of the discussion. I got an apartment and life went on as normal. I worked through my junior year, but the truth of my grandfather kept nagging away at my mind.

I thought back to my 19th birthday party. I could remember Grandpa taking a dip in the pool. When he came out, his swimsuit clung to him, creating a bulge that was at least seven inches. As he walked, the head of his cock peeked out from under the leg of his suit. It was the first penis I'd ever seen in real life.

The truth is that incest was always a fetish of mine. Incest porn, erotica, and roleplay were all guilty pleasures of mine. I'd called more than a few one-night stands "Daddy." But I'd only ever fantasized about men who I pretended were family, not actual family. Incest had always just been something abstract that I read about but now I knew that someone in my actual family had these same urges and had tried to act on them. I had a chance to try and join those rare, lucky few who had actually experienced it.

I knew there were a lot of people out there who shared my fetish. Lots of them are probably reading this right now. If you knew someone in your family was willing to try incest, would you take them up on it?

The next few weeks was a war between the angel and the devil on my shoulder. I kept making plans to go over and chickening out.

I opened the closet and selected an outfit. I put it back.

I got into my car. I got out and went back inside.

I drove halfway to Grandpa's house and turned back.

I went into his house. We had a platonic visit and lunch together.

I was a mess! I needed to get these sick fantasies out of my system! So finally, I stamped down my fears and, before the angel on my shoulder could stop me, I gave him a call.

"Grandpa? Can I come over? I know I visited not too long ago, but it's important. And don't tell Mom. Thanks."

I was committed. Not only was Grandpa expecting me, he was expecting more than just a normal visit. No backing out now.

He opened the door before I rang the bell. "Hey, Jenna. Everything okay, honey?" he asked. I could see his eyes momentarily drop to my chest, clad only in a tight white T-shirt I'd once worn to a wet T-shirt contest.

"No Grandpa," I answered. I hugged him as he shut the door. "The truth is, Mom said something to me that's been bugging me for a long time."

"Oh, what's that?"

I took a deep breath. "Mom said you were in love with her. Like, romantically. Sexually."

I saw the fear in his face and I quickly said, "Don't worry! I'm not angry at you or anything."

"Then why are you here?"

I stammered for a bit. "Well...I guess I just wanted you to know that I know. And that it's okay."

We sat down on the couch together, staying silent for a minute as everything sank in.

"Thank you," Grandpa said.

"Thank you for what?"

"For telling me you know. And that you're okay with it. I've bottled it up for so long, it's good to have someone who knows."

I put my hand on his shoulder. "Do you want to talk about it?"

My grandfather smiled. "After my wife died, things were hard. I had four kids to feed and had to take extra hours at work. Your mom stepped up. She did the cooking and cleaning. She picked the kids up from school and helped with the homework. But she did more than that. She became like more of an equal partner than a daughter. I consulted with her on big decisions. I was able to confide my pains and fears with her. Sometimes we'd even fall asleep together on the couch. That was how intimate things got between us. I remember waking up and seeing her sleeping beside me, her head on my shoulder, just like my wife once did and at that moment I realized I was in love with her. My own daughter."

I felt my heart flutter. It was so romantic. I was almost angry at my mother for rejecting something so beautiful and heartfelt. "How did you get the courage to tell her that?"

"I remember I looked up and saw a picture of my wife on the wall, smiling down at us. It was as if she was looking down on us from Heaven, telling us how glad she was that we were taking care of the family in her absence. I felt like I had her blessing."

I wiped away a tear. "It must've been hard when she said no."

"Yes," Grandpa answered. "I was so ashamed of myself. I thought that I'd ruined our relationship. It took a long time to fix things."

I leaned my head on his shoulder, just as my mother had in his story. "I was wondering if you, um, thought like that about any other people in the family."

Realization dawned on his face. "Other people in the family? Such as..."

I crossed the Rubicon. "Me."

"Are...are you saying..."

"No. Yes...I don't know. I'm confused," I answered. "Ever since I found out, I've been, well, curious."

He kissed me on the head sweetly. "Here's an idea. I'll take off one piece of clothing. Then you take off one piece of clothing. If you want to back off at any time, you can do it and there will be no hard feelings. We'll never mention this again. Deal?"

I smile, comforted by his concern about my enthusiastic consent. "Deal."

Grandpa stood up and took off his pants. He still wore his boxers, displaying that incredible bulge.

In response I peeled my yoga pants off my ass and legs, standing there in my shirt and panties.

Grandpa's shirt hit the floor, followed by mine.

Finally, he reached for his boxers. "You ready?"

My heart pounding, my eyes glued to his crotch, I nodded wordlessly.

Grandpa took off his underpants, freeing the massive snake coiled inside. It dropped free, eight inches of thick, flaccid hose. A pair of plum-sized balls dangled in the sack behind them. He was bigger soft than any of my previous hookups were hard!

I unhooked my 32B bra and tossed it aside. My panties followed. There we were, grandfather and granddaughter, seeing each other naked for the first time.

I smiled and laughed a little, trying to break the tension. "Wow," I say. "It's huge. I've seriously never seen a cock that big before. And it's not even hard!"

He smiled awkwardly. "Um, about that...there's something you should know."

"What is it?"

"Well, I'm sixty-five years old. My cock doesn't really get hard the way a younger man's does. I can't fuck you normally but I'd love for you to suck me off or grind your ass against it. Is that okay? I understand if you want to stop."

"It's okay. Can you still cum?"

"I can, rarely. It's been a few months since I've actually done it."

I smile flirtatiously. "I like a challenge."

We head into the bedroom and he lies down on the bed, his legs spread. His flaccid cock flops onto his stomach like a dead snake. I get on top of him in a 69 position and for the first time I see his cock up close. I never realized that he was so blessed by length and thickness. He must've been over eight inches long and two inches thick! I need both hands to guide it into my mouth. I put it as far in as I can and use my hand to service the rest of the shaft. My fingers just barely encircled my grandfather's girth. If this was its size while soft, imagine how big it would be hard!

'Oh, Mom, you dumb bitch,' I think to myself when I realize that she'd turned down the chance to enjoy this cock in its prime.

"Remember," he said, "Just because I can't get hard doesn't mean I'm not enjoying this, okay?"

"Mm-hmm," I answered past a mouth full of soft cockflesh.

I gently stroked the limp shaft of his cock while sucking on the head. I could feel the slightest signs of life, just the tiniest bit of swelling and pulsing. With my other hand I gently play with his giant, warm balls.

At the other end my grandfather was doing incredible things with his tongue. I felt not the timid, reluctant licks of boys my age but the wonderful sucking and licking of a man with decades of experience. Damn, Mom, you REALLY fucked up!

I try to warn Grandpa of my impending climax, but I can only manage an "Mmmph! MmmmMMMMMPH!!" with my mouth plugged his huge flaccid monster.

"J-Jenna," he gasps out. "Jenna!" For a moment, I was worried I'd hurt him but then I felt his balls tighten in my hand. Then I felt the surge of his nut juice through his soft fleshy shaft. Finally, I felt it burst into my mouth with the force of a fire hose. Months of backed-up ball cream the back of my throat. I desperately try to swallow as much of his babybatter as I can but eventually I reach my limit and have to pull his cock out of my house. It still sprays its fertile white ropes wildly, striking me square in the face and chest, while also spraying all over his legs and the bedsheets.

Finally, soaked, I get off my Grandpa and lie down next to him, our faces inches apart, my hand in his.

Grandpa has tears in his eyes. "Been so long since I've felt that. Thank you, baby, thank you."

"No," I say gasping. "Thank YOU. Mom doesn't know what she's missing."

"I'm glad you liked it. If you only want this to be a one-time thing, an experiment, that's fine. I understand."

I put my hand on his cheek, forcing him to look into my eyes and stare right into my cum-covered face. "Grandpa, I'm being completely honest when I say that was the best sex of my life. I definitely want to do it again."

And we kissed, smearing our juices between our faces, before we fell asleep together for the first of many times.
