Big Sis Taught Me

by JerseyJ

"Tanya, can I...?" Nikki stopped in her tracks, with her hand on the silver doorknob. Her jaw dropped and her brown eyes looked as if they would pop out of her head.

There, on the red-sheeted bed, was her older sister, legs spread wide open, with two fingers inside her hole. Tanya stopped when she heard the unfinished question, but her fingers remained inside. Quickly, she lifted her head and looked in front of her.

Tanya's hair, which was sprawled underneath her head and upper back, was black and shiny. She had long legs and an athletic figure, due to her frequent jogging. Her round breasts were the size of two half grapefruits, with brown, pepperoni-sized nipples. Her face was round, with a thin nose and pouty lips. With big, green eyes, she looked at her younger sister in surprise.

Nikki was twelve years old and no more than 5'2. Large, brown eyes were on either side of her small, button nose. Her curly, brown hair had a pink ribbon holding it into a ponytail. She was wearing a pink, zipped sweatshirt with light blue jeans, and white and pink sneakers.

"W-what were you doing?", Nikki stammered, breaking the awkward silence, with her eyes glued to the glistening hole that was between Tanya's sixteen-year-old legs.

Tanya crawled to the edge of the bed and sat down.

"Come here, Nikki", she said, patting the bed.

Reluctantly, Nikki walked over there and sat on the foot of the bed. Tanya moved closer, so they were sitting mere inches apart. The mouth-watering aroma of her sister's juices filled her nose.

"You never heard of masturbation, have you?", asked Tanya.

Nikki looked up and shook her head. Being six inches shorter than her, she had to look up.

"Masturbation is when a person plays with him or herself."

"You mean, like, play solitaire, or something?"

"No," laughed Tanya, "I mean play with themselves in between their legs."

Nikki dimmed her eyes and tilted her head in curiosity.

"Here, I'll show you."

Tanya pushed herself back, against a white pillow, and laid down against it. She spread her legs, allowing her right foot to dangle off the bed. Nikki twisted her upper body to watch.

Tanya's tan-skinned right hand moved between her legs, palm down, fingertips touching the bed. Her middle and ring fingers slowly traveled up her crack, through the inside of her lips, and up to her hairy mound. She then slid her two fingers down and, very slowly, rubbed her pink clit in a circle.

Before Nikki walked in, Tanya was near her climax. When she was interrupted, she began to feel a slight disappointment. Now masturbating right in front of her, Tanya's climax was making a speedy recovery.

"Mmmmph... mmmph... mmmph", she whimpered, closing her eyes and laying her head flat on the pillow. Her chest heaved up and down with every quick, short breath, making her firm breasts jiggle a little. "Uuhhh... uhhh... ooooooooh..." Tanya grabbed the sheets with her left hand and lifted her butt a few inches off the bed. Her hips thrust up and down, meeting her right hand, which massaged her labia even faster.

Just then, a stream of clear liquid gushed out of Tanya's hole and splashed the sheets. Nikki pulled back in surprise as a few warm drops landed on the back of her left hand. She looked down, at her hand, then up, at her sister, whose hands were a blur on her wet cunt.

"Oh... my God", gasped Tanya, finally taking her tired hand from between her legs. She then stuck her pink tongue out and put her wet fingers on it.

"Eww!", Nikki exclaimed, making a sour face. Didn't you just pee on them?"

Once again, Tanya had to laugh at her sister's ignorance.

"This isn't pee", she explained. "It's cum. Cum squirts out of my cunt when I masturbate for a long time. It tastes really good." She stuck both fingers into her mouth and pulled them from her sealed lips.

Watching her do that reminded Nikki of the drops that were on her hand. Carefully, she raised her hand and stuck her tongue out. Her hand connected with her tongue and she hesitantly rolled it across, gathering up the sweet juice in one swift lick. She closed her eyes and rolled her tongue around the inside of her mouth. She was relieved that not only did it not disgust her, but it actually tasted good.

"Nice, huh?", grinned Tanya.

"Yeah. It was", replied Nikki. "It tasted really sweet. Like sugar."

"Do you want some more?"

"Yeah."

Tanya dug her fingers deep into her cunt, before pulling them out and holding them in front of Nikki's face. The younger girl swirled her tongue around the wet digits, before she wrapped her lips around them and sucked them up and down.

"Mmmm", she grinned. "Will you show me how to masturbate, now?"

"Okay", smirked Tanya. "First of all, take your clothes off."

Obediently, Nikki pushed her right sneaker off with her left foot, then did the same with the opposite. In her clean, white socks, she stood on the dark brown, wooden floor and unzipped her sweatshirt, hanging it on the doorknob. A black training bra was underneath the shirt, which she took off and dropped on the floor. Two small mounds, complete with two, dime-shaped nipples, were revealed. Tanya propped a pillow horizontally against the white wall and leaned against it as she watched her topless sister step out of her jeans. Nikki then pulled her black panties down, stepping out of them and flinging them aside with her right foot.

The sisters were now completely nude together, for the first time in years. They used to share baths, but that was long before either of them hit puberty. The two of them looked each other up and down, comparing their bodies. Like Tanya's, except with less hair, Nikki's pubic hair was bushiest at the mound, with lighter hair surrounding the pink slit. The brown nipples on Nikki's chest were an average size, while Tanya's stuck out like hard, pencil erasers.

Nikki got into bed and sat, legs crossed, in front of her big sister.

"Okay", breathed Tanya. She was clearly turned on at seeing Nikki strip. "Let's get started. Take two of your fingers and put them here." She demonstrated by putting her own middle and index fingers on her clit. "That's your clit. It's very sensitive. You rub it like this."

Accompanied by a gasp and a shudder, Nikki learned how sensitive it was when she touched it for the first time. Carefully, her fingers went back down. This time, she was able to rub it like her sister was also doing. This feeling was like nothing she had ever experienced.

"Also, you can stick a finger or two inside of your cunt, like this." Tanya stuck her left index finger into her hole, up to the knuckle. She left it in there and looked at her sister.

Nikki stopped rubbing her clit and stuck her left middle finger up her moistening hole. They pulled their burning fingers out at the same time, both fingers warm and glistening with female juices. Nikki brought her finger to Tanya's face and stuck it into her mouth. Eagerly, Tanya's lips sealed it inside and her tongue swished all over it, tasting the delicious juice. She did the same to Nikki, prompting her to swirl her tongue all over the fingertip.

As she sucked her own sister's juice off her sister's finger, Nikki's fingers went back to her clit. She thought this was the better out of the techniques that Tanya taught her. Despite a recent orgasm, Tanya began to get another urge. She laid back, against her raised pillow and mimicked Nikki's movement. They stared in between the other's legs, clearly turned on by the presence of another nude girl.

"It... feels so... good", moaned Nikki, rubbing faster.

"Yeah", agreed Tanya.

"Uuuhhh... uhhh... uuuuhhh... I feel... funny... what's happening?"

It turned Tanya on even more to know that her sister was ready to cum right in front of her. In anticipation, she brought in her other hand, massaging her dripping cunt with two hands. One went up, while the other went down.

"Let it out!", she panted. "Keep going!"

"Oww... ooooohh... oooohh... ooooohh... eeeeeeeeeeeeee!!" Nikki's orgasm was a powerful one. It felt like a bomb had gone off inside of her and the explosion hit every part of her body's interior. Her body spasmed wildly as her fingers became a blur on her clit. She bit her lip and her face reddened. She then turned over, laying on her belly, and madly ground herself into her hand.

Watching Nikki cum so hard, and now watching her round, butt cheeks clench and unclench while she humped her hand, was more than Tanya could handle. She scooted down lower, until she was flat on her back. Her moans increased into screams of pleasure.

"Oh, God! Oooohhhhhh!! Ahhhh!!" Tanya spread her long legs as far as they could go and rubbed up and down her labia, squishing it in both hands. A gusher-- even bigger than the first-- squirted out of her cunt. It glided through the air and landed a few inches in front of her, leaving dark, wet spots on the bed. "Mmmmmmph!"

When Tanya stopped cumming, she scooted further down, where Nikki was. Nikki had also stopped cumming. They laid, a sweating heap of cum-soaked, female bodies, catching their breath. After a while, they propped themselves on their elbows and began to talk.

"That was so cool", beamed Nikki.

"Sure was", replied Tanya, stroking Nikki's bangs. "I don't think I'd ever cum that hard, right after a first session, before. You came kinda hard, yourself."

"Must run in the family", she laughed, causing Tanya to do the same. "I hope my next cums are like the one I just had."

"I doubt that. The first is always the best."

They laid there in silences for three minutes.

"Hey, Nikki? What did you want to ask me?"

"When?"

"When you walked in the room and caught me."

"Oh. Can I go to Samantha's house?"
