Sister is hooked

I opened my eyes and was surprised to see little run up to the bed, and jump on it. She stood on the bed, her feet on either side of my hips, raised her skirt above her waist and excitedly pointed at her naked cunt, which was split by a slim pair of pussy lips. The mound was very chubby with fat and had sparse hair.
I couldn’t help but look with interest at her cunt which was beginning to look like a mature and in all probability fertile. This was a very odd situation, my sister had nearly shoved her pussy in the face and was saying look, look.
I raised myself from lying position on bed, with face nearly in level with sister’s cunt. The strong smell her hormones mixed with urine is what hit me first. I leaned further nearly burying my face and furrowing the nose in her cunt. It was very exciting and unexpected development. I did not want to lose the opportunity to see, touch and feel her little cunny. I turned and twisted to have a proper look and then placing my palm on her mound moved it upwards slowly towards her clit.
In her desperation for me to admit that she had matured in to a lady, she did not realise that her brother was touching her, feeling her and taking a good look at her cunt.
Now on stop calling me ‘little”.
As I fondled her cunt “very attractive kitten, and a long time to go before it develops in to a mature and lovable pussy”.
Sister blushed and blurted ‘this is not good enough?
No, the mound has to be covered with not less than 4 to 500 hair follicles.
I can help you, every so often to check on the number and growth. How's that? If you want to hasten the pace of hair growth then, stop wearing panties when at home, circulation of air around your slit will help.
I smiled to myself at the cunning ruse.
Disheartened she plopped down astride on my abdomen, feet on either side, and knees held together. Her elbows were on the thighs and rested her chin in the palms. In an effort to cheer her up I pulled her up to my chest and slowly parted her legs revealing her cunt to my gaze. Her cunt lips were thin and pink in colour but closed. Had the urge to get a glimpse of her innards, so lowered my left hand towards her cunt. With the thumb and the fore-finger I teased her cunny lips apart revealing the dark pink inners. With her cunt lips open the scent of her hormones and urine wafted through to my nostrils. It was thrilling, I had a hard on which she was not aware of. As I traced my fingers along her slit, she squirmed and soft moan escaped her pursed mouth. With my continued manipulation wetness had spread in her, her insides were lubricated by the unexpected secretion.
I became slightly bolder and ran my finger upwards towards and over her wet pussy, to her clit pressing the small protrusion as shiver passed through her body.
I had a glimpse of girl’s clitoris for the first time. He knew the place to concentrate on in future. This was exciting.
Sister herself was unable to control her excitement, she raised her hips by almost three inches off my chest, and her cunny nearly hit my nose. She quickly lowered herself and put a hand over her mouth to muffle her soft moan.
I could not remember ever seeing anything so beautiful. She was so cute the way she sat there with her eyes closed and her mouth open, lost in anticipation and pleasure.
That feels so good. She gasped “feeling like I am in heaven.
I guided her off my chest and made her lay on bed beside me.
I unhiked her skirt and eased it off her waist. Now her mound lay bare in front of me, I leaned my face over to smell her. Her sexual fragrance was very sharp God! my hormones were on fire for it! I put my face to the soft mound and kissed it. I kissed and kissed and kissed that beautiful thing, savouring its alluring odour. I began to work kisses into the moist slot between the fleshy pads of her pussy and put the tongue out to taste her feminine secretions.
She opened herself for her brother as I grasped her baby-soft hips and continued kissing and licking the tasty, scented slit between her silky legs. She gripped my shoulders, and I could sense her body quivering and hear her making the sweetest little sounds as I licked into her. Nothing I had ever done, in all my life, turned me on as much as this did. I had to have more of it!
I was trembling from the effects of pure lust. I pushed my tongue deeper into the oily-wet cleft, licking and tasting the flavour of her most personal place. The whole time she made more little squeaking noises as the thrill, of what her brother was doing to her, made the breath catch in her throat. I could tell that she liked it because of those sounds she was making and because she began pushing her pussy up, at my face, from the bed. It was wonderful! I rounded my arms around her hips and placed my palms on her breasts still inside her top and bra, fondling them, and continued licking her wetness.
Oh my god! Yes! Ohhhh, yes, that's it! Lick it for me, lick it softly for me." She squealed in pure ecstasy.

Oh, sweet baby she squealed with joy, the intense pleasure was almost driving her out of her mind, her entire vaginal area melting with heat and moisture. She was not even aware of the gasps and moans of joy that were coming from her lips, and the incredible sensations of her brother eating out her wet cunt. Her pleasure was mounting, and so was her moaning. She was quivering with anticipation and very wet as cream started streaming steadily out of her pristine depths. The pre-orgasmic sensations pleasured her body, her groans and moans became louder and louder, and she started thrashing her head on the pillow. She arched her back up and pushed her mound in my face, and then with her hand pushed my head firmly on her pussy. As she neared her orgasm she clenched her thighs around my face and tightened her cunt muscles around my tongue. And then the dam burst, and the juices spurted out from her vagina drenching my face. As her orgasm ebbed she released my face from the thighs. I wondered, if this was her first orgasm, I had accomplished the goal.

After longest time my sister opened her eyes and gazed dreamily at me, it was divine.
“Wow! it was so good when you put your tongue in. I never knew of such pleasure. But is it not Icky? I mean pee comes from there”. How can you do it?”
No, not at all. I have to say it was the best thing I have tasted and smelled. You are so sweet, so yummy, so delicious. Only thing better than this would probably be getting to smell and taste mommy between her legs.
Little still in ecstasy did not listen to what I had said but dreamily responded Will you do it again?
I was convinced this was the new beginning to incestuous pleasure.
