Bella was reaching out to touch herself under the sheet, trying to be quiet as a mouse as she shared the room with her brother. The room was dark but the moonlight hit some of the forms and many times in the past she stood quietly for hours, waiting to hear his deep breathing before she could finally have a "private" moment.
Tonight was no different, she opened her legs just a bit, shot a glance at the bed across the room, and felt her way down her clitoris that was emerging between her swollen lips. She kept her eyes shut as she started to rub harder and fell into her fantasies.
John was not asleep. He was waiting. Two weeks ago he had accidentally seen his sister, legs spread open, touching herself. He couldn't remember what had woke him up but as he turned, the sight of her pussy in the half light of the moon and the lamp of the street gave him a shock. He stood there, unable to think, unable to move, unable to even swallow. He thought of making noise so she d pull the sheets and cover herself, to save her the embarrassment. He would be mortified if he was in her shoes. But he couldn't do anything. And then horrified he realized he had an erection.
Guilt and fear overcame him.
He turned the other way and tried to reason with himself. He didn't jerk off today, the penis has a mind of its own. He focused on his sister. The same sister that was always antagonistic, making fun of him, defying him. The same person he saw crap, burp, fart.
"She is not a woman" he thought.
"Its fucking Bella for crying out loud".
But that didn't help.
"I need to get laid, fast" he thought to himself. At 18, he wasn't very experienced. He was a very good looking man and girls were throwing themselves at him but he didn't notice, he was too inexperienced to read the clues.
Two weeks of agony passed. Two weeks of avoiding eye contact, of self doubt, of excruciating guilt.
Two weeks of abstinence.
Every time he reached for his cock, that shiny wet pussy was burned in his mind. He was obsessed and suffering, but as days went by, and as he kept bumping into his sister, he realized there was no escape, those feelings were here and they were real. He was attracted to her. And with acceptance came release, and plotting.
Each night, when she would fall asleep, he would crawl on all fours till he reached her bed. He would then lift the sheet up with one hand while have a torchlight in the other. It was Spring and Bella was wearing only a cotton short nigthy. And as far as he could remember she was a heavy sleeper who even occasionally snored.
For two weeks, every night, he would lift the sheets, and watch her curves as the nighty would be up to her waist. Different positions allowed him to scrutinize her breasts, half popping out of the material, or the crack of her ass if her legs were spread.
He would never touch her, just shift positions around her bed while on his knees, engulfing her beauty and stroking himself while the torchlight was held between his teeth.
Once he would have his vision filled with her flesh and semi hidden secrets, he would rush to his own bed and jerk off. Sometimes, more than once.
One night Bella woke up and saw her brother playing with himself. She saw his back and his hand moving. It wasn't hard to understand what he was doing. She felt amused and for a moment felt like embarrassing him. But something about his back, the way it showed, the muscles and the width of his shoulders, made him look older...manly. Not the young idiot she liked to tease. She decided to respect his privacy and felt ashamed for witnessing such a private moment, so she turned around and smiled. Still the sight of his back and the realization he wasn't a boy anymore but a desirable man made her feel a bit strange.
Three nights ago, John waited for her to fall asleep as he did every night. Lately he had expanded his voyeurism and watched her through the keyhole of the bathroom. He couldn't see much but just the idea was enough to send him riding to heaven. He moved closer to her bed, lifted the sheets and gasped. For some reason, Bella had taken off her underwear. It was down on her ankle. Her legs were slightly spread, one up against the wall.
He squeezed and pushed his cock downwards at the sight. He positioned himself closer and tried to inhale her aroma, but he was too far away. He stood there in a daze, mesmerized by that sight, the full lips, the curly trimmed hair, that gorgeous clitoris who was looking like a tiny little bud. He wondered how lovely her pussy would look when it would be engorged and swollen. Just the thought made him squirt a little bit of pre–cum in his pants.
He threw caution to the wind and decided to jerk off right there and then. He grabbed his cock from the slit of his boxers and set it free. His cock and hand were partially underneath the bed and he reached out with his free hand to lift her nighty just a little bit, just where the fabric stopped and hid the beginning of a gorgeous nipple. His hand was light and he succeeded in freeing her pointy nipple, feeling he could faint from delight at the sight.
He couldn't stop himself, he came and his semen hit the mattress from underneath.
He quickly went to the bathroom and brought toilet paper to clean his mess.
He was still hard and his heart was beating fast.
As he tried to clean up the proof of his sin, he looked up to check on his sister. She was still asleep but had changed position. She was on her back, hugging her pillow, one leg bended, the other one spread, offering him a full view of her two holes and the perfect mounts of her ass.
He got up and stood in front of her.
He coughed. No reaction. "Bella?"...
No answer. Her breathing was as deep and as rhythmical as before.
With a trembling hand he touched with the tip of his fingers, the skin of her ass. Ever so gently. She didn't move.
He let her finger slide, light as a feather, between the cheeks, at the beginning of the crack.
Felling brave he lifted his hand and went the other way, stroking her lips gently, moving onwards to her asshole.
His cock was throbbing so he changed hands. He started pleasuring himself as he repeated the same movement, again and again till the lips opened slightly and he felt she was moist.
He almost fainted from desire. He wanted to shove his tongue in that slit, to roam he holes but he kept his cool. He knew if she woke up it would be a disaster. It was his sister and he was taking advantage of her. He was a pervert all the way, but at this moment in time he didn't care. His lubricated finger kept stroking her pussy and ass hole ever so lightly, but it was enough for him to feel her loosening up, opening. His finger stopped at her anus for a second and he pressured just a tiny bit, just to see...and he felt she was opening. Not too much but enough. He resisted his urge and it was fortunate cause at this point Bella moved and groaned and started waking up.
John stood on top of her, cock in hand, panicking. He hit the floor and crawled to the end of the bed where she could not see him. His erection was killed, his fear had overcome every desire.
Bella wanted to pee like hell and John was in the bathroom for ages. She knew he must have been doing his business but still, she had rights too. She banged on the door, but got no answer.
She heard water.
"Are u in the shower?"
