Desc: Incest Sex Story: Chapter 1 - Grampa is looking after his special Lil' One while her parents are out for the evening

"What's that thing in your pocket Grampa?"

I am babysitting my grandchildren, two girls and a boy, while their parents and the other grandparents, my son-in-law's mother and father, are at the prize-giving dinner at the golf club. Claire and Tony, the young twins are in already dressed for bed. Before leaving, my daughter Dawn, said that because there is no school tomorrow, Cassandra, the eldest girl can stay up until ten-thirty.

"No later than that though, Dad! I know she loves being with you, but Cassandra is a hellcat in the morning if she doesn't get her sleep. We will be home around midnight, ok? Maybe later if there is a party to go to after the club."

I tell her not to worry; they can stay out as long as they like.

When I came back to my armchair to watch TV after putting the two little ones to bed, Cassandra, Cassie, plonked herself down in my lap and she has remained there ever since. She is a budding beauty who will become one day a very lovely woman.

Cassie and I have been best buddies forever. She has always been My Lil' One. A special bond developed between us right from the time in her infancy when she came to realise there were other important people around aside from her mother; a bond that pissed her dad off quite a lot at first, because he thought he should be the number one man in her life. He slowly came to accept my special place in Cassie's affections, but it took a few years.

Tonight when I arrived she greeted me as always with a long, tight hug. Her firm little breasts pressing on my lower chest reminded me of how quickly she is growing up now. And since the others left for the golf club she has been all over me like a rash; much more so than usual. It seems as if she is coming on to me. Apart from the fact she is my granddaughter, I am not quite sure how to react. Naturally, I am flattered, but she is, after all, 'only' a high school kid and I am much more used to relating to the young women thronging the University where I am a Professor.

I work on keeping things on a sane level by discussing the mundane things, but she will keep moving around! Then comes that awkward question...

"What's that thing in your pocket Grampa?"

What would you say if you were me?

Could you tell Cassie that she has a gorgeous body and that the constant shifting of her alluring, tight butt in your lap has got your dick so hard it is throbbing with excitement?

Could you tell her that her short denim skirt has ridden so high up her creamy, smooth thighs that you can see almost all the way up to the top? And that you are imagining how silky smooth her skin would feel, if only you could stroke it?

Could you mention how sexy her soft, rounded tummy and little bellybutton are and that you can see all of that because her tee shirt has parted company with her skirt?

Could you say that her skirt is far too loose at her waist? Consequently, you can see down under the waistband to the enticing boundary between her tummy flesh and her cute sky-blue panties? Could you say you would give your eye teeth to be able to lift the edge of that blue cotton band and look right inside to ascertain without any doubt that she truly is a natural blonde?

Quite a dilemma, you must agree. But, as the infomercials on TV say, there's more!

How would you go about telling Cassie that the cute cones of her fresh, bra-encased breasts are wonderful? And that her nipples are visibly hard and so clearly defined by her tight tee shirt that you want to pull it and her bra right up and off her so that you can see them properly?

How would you say to her you are busting your balls to take those firm globes in your palms to caress them, to make her teats stiffen even more and tweak their sensitive tips until she squirms and writhes in your lap in ecstasy?

What do you think she would say if you told her you are nearly creaming your pants with wanting to spread her legs wide to lick up the honey-salty juices from her golden-fringed, pink pussy, while you inhale her sharp scent? A scent more exciting than a mere girl's, but not yet a woman's!

If you were me, how would you encourage her into saying that she feels the same way about you and then watch her slim fingers tentatively take hold of your throbbing, stiff man-shaft and guide its bulging crown to the very entrance of her tight virgin tunnel?

Would you be able to tell your delicious young granddaughter that your hard, throbbing dick is saying to you with no room for contradiction that you are a 'Dirty Old Man'?

How would you tell this teenage goddess that right at this moment you desire her more than anyone on the planet?

Of course, I don't have the courage to say any of these things. I block the dangerous, lascivious thoughts out and, ignoring the heat of embarrassment rising in my cheeks at having thought them in the first place, I say...

"It's nothing."

Cassie wriggles her bottom again; "It doesn't feel like 'nothing' to me!"

"Stop doing that!" I say, trying to sound as if I mean it and failing miserably.

She looks at me archly, "Why, Grampa? Don't you like it?"

I feel my face flush hotter. Of course I like it, but I cannot say so.

"I know what it is anyway ... it's your dick! Can I see it?"

"No you can't! And how come you know that's what it is, Smarty-pants?"

"Come on Grampa, we have been having sex education classes at school since I was Tony and Claire's age! I know how boys are built and what a dick is! And, anyway, Gavin has shown us his."

"Oh yes ... who is 'Gavin' and who is 'us'?"

"Me and Megan, my best friend ... Gavin is her older brother..."

"And he shows you his ... dick?"

"Only if we let him look at our pussies ... Grampa, why do boys call girls' vaginas 'pussies'?"

I resist the temptation to say, "Because they are hairy and they purr when they are stroked." Instead I ask, "Why don't you just tell me about that boy Gavin ... you're getting quite grown up now ... So, Gavin gets his dick out while you take your panties down? How often does he do that?"

"At first it was only every couple of months or so. Then he persuaded us to do it more often and now we do it twice a week ... sometimes three times ... whenever I go to Megan's after school."

"How do you feel about him doing that?"

"I didn't like it much the first time, that was last year, but Megan had done it with him before as a dare and she said it was really cool ... It is sort of exciting 'cos we know we shouldn't let him look at us like that."

"Do you like looking at his dick?"

Cassie blushes and looks uncomfortable; "Yes ... it's a lot different from the drawings in the books at school though..."

"And, how about Megan's pussy ... do you look at that as well?"

"I've never really seen it ... we always keep our skirts on while he's looking at us..."

"Not even when you go to the bathroom together, like all girls do? And surely you two have slept over at each other's houses and seen each other undressed at bedtime?"

Cassie shrugs, "I've never thought to look."

"Has Gavin ever touched you on your pussy?"

"Noooo... !"

I am now so aroused my cock feels as if it's about to burst. I press on with my questions; "Does he do anything else at all?"

"Well, we sit on the floor with our knees drawn up and he sits opposite us quite close and looks up our skirts so he can see everything. And he ... then he rubs his dick ... and he goes all red in the face."

"Do you like watching him do that?"

"He looks kind of funny sometimes..."

"Does he ever ask you to rub his dick for him?"

"He did the other day."

"Did you do it?"

"I didn't, but Megan did it. Afterwards, she said it was really neat and that I should try it next time. Gavin also went to her bedroom that night when their parents were asleep and got her to do it again. He put his hand in her pyjamas as well, but she wouldn't say what he did."

"Does he cum?"

"What's that?"

I decide to bypass that question and just mutter, "Oh, something boys do."

She wriggles her bum against me again and whines, "Oooooooh, pleeeeze Grampa, let me see your dick! I'll let you see my pussy..."

Despite my desire to look at her, I balk. "No I can't, Missy, if anyone found out I could get into a heap of trouble."

"I won't tell! And Claire and Tony can't either; they're in bed."

My resolve weakens. There's no real harm in letting her look is there? It won't go any further than that!

"Oh, alright then. You get off me and go and stand over there." I point to a spot about two feet away. "Now, not a word to anyone ... right? Not even Megan!"

Cassie gives me a swift buss on the cheek and says, "I promise" before climbing out of my lap. Her lips are so soft and warm. She parts her legs as she climbs out of my lap and I look up her skirt to the crotch of her panties. It looks damp and I nearly shoot my load in my pants.

With trembling fingers and a thumping heart I unzip my chinos, undo the fly buttons on my boxers and release the monster from its lair. It sticks up, stiff and straight from my groin. It seems to be pulsing in the cool evening air. I raise my eyes to Cassie's face. Her eyes are round saucers and her soft pink lips form a perfect circle of wonder. Mentally I urge her to drop to her knees and press their softness to my throbbing shaft, but she is not a mind reader, thank goodness!

"It's much bigger that Gavin's is," Cassie says in a small voice.

"That's because I am a grown up ... his will get bigger as he gets older ... come on, it's your turn now." I can't wait to see what her pussy looks like!

She tricks me. One! Two! Three! Four! Cassie lifts her skirt; pulls down the front of her panties; lets go of them again; and lets her skirt hem fall. I catch the merest glimpse of golden curls and the start of her gorgeous crease before it is gone again.

I laugh, knowing that I've been 'had' and move to tuck my dick back into my pants.

"Aren't you going to rub it like Gavin does?" Cassie asks me.

I laugh again; "Well you didn't show me your pussy properly did you?"

She blushes a deep pink. Realisation hits me. Come on Man! She is shy with you! Probably if she had the 'moral support' of her friend Megan now, it would be different!

"Okay, Sweetheart! If you don't really want to..."

"I will, but promise you won't laugh."

"Why should I do that?"

"'Cos you're a grown up and you've seen grown up pussies..."

Well it's true that I haven't lacked for hot willing pussy in the last few years or so since my wife died. Many of the new female students go wild as soon as they get out from under the watchful eyes of their parents and I unashamedly use my position as their Professor to take full advantage of the opportunities on offer!

As for that prick Gavin! These young chicks are the closest to real pussy he'd be getting or he wouldn't be so anxious to do what he does with them.

Without thinking about the fact that my dick is still sticking out of my pants I reach out and pull Cassie to me. I hug her tight and tell her that I would never, ever laugh because she is much too beautiful. Then I realise that my tool is pressed against her soft, smooth thigh and I nearly lose it there and then. Hurriedly, I let go of her and she takes a step back. Cassie doesn't appear to have noticed anything unusual, but I can see a glistening smear of my pre-cum on her leg.

She smiles happily, "Okay, I'll do it."

Cassie undoes the buttons at the waistband of her skirt and lets it fall to the floor. Jeez, her legs truly are beautiful! Maybe it's because her panties are so tiny, but Cassie looks a lot taller without a skirt on. I lick my lips and my breath catches in my throat as she hooks her thumbs into their waistband and pulls them down. She hesitates just above her pubic area, and then with a determined look she pulls her panties right off. My pounding heart feels as though it's going to come bursting thorough my ribcage at any moment!

Cassie looks at me with uncertainty on her face and then relief when she sees the dazzled expression in my eyes. I hold out my hand to help her balance as she steps out of the discarded garments. She steps close and cuddles me again. My rampant cock is nestled in the valley of her thighs; its head is only millimetres from her virgin slit. Surely she can feel it! I want to slide my hands down her back and cup her delicious rounded little buns and pull her onto my dick. But I don't dare!

"Last time," she says in a shaky voice, "Gavin took his jeans right off."

'This must be really getting to you young lady, ' I think as I undo my belt and the clasp at my waistband, 'I wonder how far you'll let me take it?' I put my hands on the chair arms and challenge her; "You do it!"

Cassie steps back a pace, staring hard at my erection and biting her lower lip with uncertainty. I make her look up at me and hold her eyes in a steady gaze. I clench the cheeks of my buttocks, making my abdomen and rampant cock jerk in her direction. She drops to her knees in front of me and starts to tug my pants down. Cassie's face is so close to my throbbing tool I could easily clasp her head and lead her to take it in her mouth! But once again I chicken out.

I lift my ass off the chair and she pulls my pants from me. Then she pulls down my boxers. Cassie's look of wonder returns as she stares at my thick black pubic thatch and my balls dangling in their sac between my spread legs.

"Are you going to rub it now?" she asks again.

I want to. But more than that, I want her to do it for me. "Do you and Megan rub your pussies when Gavin does it?"

She looks at me as if I have suggested something seriously weird.

"Don't you ever rub your pussy?" I ask.

"I touch it sometimes in bed..."

"Does it feel nice?"

"Oooo, yes!"

"Do you give yourself an orgasm?"

Cassie's eyebrows crease uncertainly. She hasn't learned how to masturbate properly yet! I want to show her how. I say, "I want to show you something. Will you let me rub your pussy?"

She looks at me doubtfully for a moment, and then nods her head.

I tell her to stand up; then I reach out and slide the tip of my 'social finger' along her slit and in between her legs. She is very soft and warm, and very dry. I withdraw my finger and wet it in my mouth. I catch a brief sense of her sex odour and taste. When I insinuate my finger between her legs again it slips into her crack easily. I find the entrance to her tight hole and rub it gently. She releases a little rush of slick moisture. This is what I am looking for. I collect it on my fingertip and move it to where I know I will find the hard tiny button of her clitoris. She gasps and tries to move away when I first touch it, but I follow her and she allows me to give her pleasure.

I suggest to her that she will be more comfortable if she leans on my leg and I guide her to half sit half stand with her bare bottom resting on my thigh. She reaches out to steady herself with a hand on my shoulder. Placing her in this position makes Cassie open her legs naturally, which allows us both to watch my busy finger doing its work. She is fascinated at the sight and with the sensations I am inducing in her.

"Is that nice?" I ask her. She nods her head with a dreamy smile on her face. I tell her to put her finger where mine is, "So that I can rub myself like Gavin does."

"I could rub you, if you want ... I know how to do it"

My cock leaps with anticipation. Of course she does, she has watched Megan do it to Gavin. Throwing caution to the winds, I say: "Go to it!"

The feel of Cassie's inexperienced fingers circling my shaft almost sends me over the edge. She hesitates for a moment - probably surprised at how hot my dick is – then she starts running her hand slowly up and down its length. A bead of pre-cum emerges from my tip.

"Am I doing it right?" she asks.

"Just perfect!" I gasp, getting closer and closer to an explosion.

I find her little hole again and slip the tip of my finger inside; she is wet enough, although very tight. Cassie guesses that I want to put my finger right in her. She is afraid, but at the same time, she wants to learn what my invasion will feel like. She opens her legs wider. I accept this sign of encouragement with a smile of appreciation and murmur, "Are you okay?"

Cassie nods, but winces with pain when I try to push my finger further into her channel. I keep my fingernails very short, but I may still be scratching her tender walls. Or maybe it is the sheer size of my middle digit? My index finger is much slimmer so I withdraw the one causing the pain and move to replace it with its smaller companion. I have to wet it first with her slippery juices and I touch her clitoris while doing so.

Cassie cums with a little squeak of surprise followed by sharp cries of pleasure. In the heat of the moment she grips my cock hard in just the right place and jerks her wrist. Sperm boils out of me in leaping spurts, splashing onto her belly and thighs and dripping to the carpet. All of these frighteningly new and wonderful sensations are too much for her and Cassie collapses against me. I hold her tightly while her orgasm courses through her body and my own ecstatic pulses subside.

When it is over Cassie is dewy-eyed and languorous, and very curious about the pearly white glistening slime that streaks her skin. "Is that what boys do?" she asks.

I tell her, "Yes."

"The books at school call it ejaculating..."

"I know..."

Cassie notices that my dick is slowly shrinking and softening in her grasp. I say wryly, "Boys do that after they ejaculate ... cum. Don't worry, it's normal. If you want to, you can soon make me get hard again." Cassie nods enthusiastically. Then she experimentally dabbles her fingertips in a patch of my slime on her belly. Once again, fascination takes over when she feels how slippery it is.

I have now stepped over the boundary of reason. I want to corrupt her more, to lay the groundwork for a later time. Or do I even want to set her up for Gavin to enjoy? I take hold of her hand and raise her sticky fingers to her lips. I smear my sperm over the soft pink flesh. Cassie cannot resist. She puts out the pointed tip of her tongue and licks. She may not love the taste, yet, but she does not grimace with disgust. I collect a larger gob with my finger and raise it to her mouth. She is a smart girl; she opens up and lets me slide my finger inside. Cassie tastes herself and me at the same time. I collect every drop of cum from her body and legs and she eats it in silence, staring at me all the while with trusting eyes.

Cassie stands up and moves in close to give me another hug. I cannot leave her body alone. I search for her pussy from the rear; she is still very wet; the insides of her thighs are slick with moisture. Cassie wants more of this too. She moves a leg slightly to one side and pushes her bottom out to give me easier access. She loves the sinful path I am leading her down!

I find the entrance to her sex with my index finger and slide it in. I slip in deeper than I did before, much deeper, and this time she does not show pain. I fuck Cassie with my finger, pumping her velvet channel slowly, gently. Her head rests in the crook of my neck now, her trembling, gasping breath rasps in my ear.

My index finger is in as deep as it will go in this position. Slightly frustrated, I remove it and Cassie moans in protest. Her protests turn to pleasure when I replace it from the front with my much fatter, much longer 'fucking' finger. This time it slides in without a problem, deeper and deeper into her hot, welcoming little body. I encounter a small resistance at which she protests slightly, but I brush the obstruction aside and her complaints cease. I see a thin trickle of bright blood appear on her thigh.

All thoughts of Cassie not telling Megan about tonight are gone. I ask her, "Next time you go to Megan's house and Gavin is going to be there, will you take me with you?"

Cassie humps on my finger and then replies; "I'll have to ask Megan first."

"That's cool. Will you let me know?"

"Sure..."

Cassie parts her legs wider and flexes her knees, inviting my finger to take her entirely, as deep inside her as I can reach. My re-awakened shaft slips between her spread thighs and falls against my hand. The unholy thought springs into my mind. With my free hand I grasp my erection and direct the slimy bulging head against her slippery crease. My cock is so much fatter than the finger it is going to replace; yet, it will slide in so easily! I slide my satiny crown between her plump, slick labia and she moans softly.

"Do you want to fuck?" I ask her.

In a barely audible, trembling whisper, Cassie answers, "Yes... !"

I pull her onto me, dragging her on knees astride me as I sit in the chair and boring my rigid shaft into her wet slippery warmth. I strip her tee shirt and bra from her, licking her hard-tipped breasts and nipping her nipples between my lips. Cassie rubs her breasts on my face, pushing them against my mouth. Again and again I thrust and thrust. Her tight little snatch grips and squeezes my pounding cock like I have never felt before. She writhes in my lap, meeting my every lunge with one of her own. We grind together, lost in the throes of lust. I am fucking Cassie! I am fucking Cassie! Cassie is fucking me! My balls contract. I am cumming! I am cumming! Oh Sweet Jesus, I am cumming! I am filling My Lil' One's teenage schoolgirl cunt to overflowing with floods of my creamy thick incestuous sperm!


I come to with a start. God! What a dream! With my eyes still closed I shake my head muzzily.

The armchair shakes again; a repeat of what first dragged me from my slumbers.

"Why is the front of your pants all wet, Grampa?"

Cassie! God! I had a wet dream! About her! Whatever must she think of me?

I open my eyes to be confronted by a perfect vision. My granddaughter is sat on the arm of the chair with her legs dangling beside mine, almost touching. She is dressed for bed in a short, thin nightie. I remember now that she left me a while back to go and change. She has no bra on. I can see the shadow of her nipples clearly. They are hard, making sharp-tipped tents of the soft fabric. My eager gaze falls to her lap and legs. The nightdress only reaches halfway down her thighs. They are parted. I see under the hem to the pale sky blue of the panties hiding her crotch...

Desire, stronger, fiercer, more overwhelming than any I have ever felt in my life before roars through my entire being. Even though I ejaculated just moments ago, blood surges into my dick, making me instantly hard.

With my heart thumping like a steam hammer I reach and place my hand on the warm, silky flesh of her inner thigh, just below the hem of her nightdress.

I look up at her face.

Cassie smiles...
