Halloween
Ten Years Ago
She stared at the girl coming down the stairs from her brother's room. The girl could not have been up there for more than five minutes after they made out down here for about the same amount of time. She only heard him grunt in pleasure - he was a fast shooter, her older brother, she knew that very well from hearing him in the room next to hers with his girlfriends.
This one, who just left the house now without even noticing her boy's younger sister, had a smile on her face. Not one of sexual gratification but of being happy to be noticed by one of the hottest guys in school. The girl somehow didn't know any better, didn't think of demanding her own gratification from him.
The sister looked into the mirror next to the coat rack in the hall. She was naked, her slender body not particularly impressive, her B-cup breasts small, her hips slim. She knew she had a strength inside of her that others didn't perceive, she felt it grow as her body has changed and she turned into woman up onto this day, her 18th birthday.
When she had made the fateful discovery some weeks ago and her life and emotional state changed forever, it started to simmer. Boil. Now, on her birthday, Halloween, it was ready to break out.
She looked down at herself -- naked, except for the instrument of her rage she chose. She had skipped school today, spent the morning to drive to the City, visiting a Sex Shop to get it. She had been carded, of course - the man in the shop had grinned at her lewdly when noticing the date of birth on her ID being October 31st, 18 years ago exactly.
"Happy birthday, young lady. Couldn't wait to get some toys, hm?"
He had winked at her - she hadn't given him any more attention, just gone to the rack and picked the biggest tool they had available. He had gazed at her - not what he had excepted her to buy, but her emotionless face and staring eyes had stopped him from making any further comments.
There had been no party - she didn't have any friends in her school, hardly ever talked to anyone. Her mother had made her a cake and she dutifully blew out the 18 candles that morning and that had been it.
The REAL present for her 18th birthday she was about to give herself. Right now.
Slowly, without hesitation, she walked up the stairs, her new strap-on dildo of choice softly bopping in front of her hips.
She opened the door to her brother's room, it gave a soft creak that he didn't hear, so he kept posing in front of his full body mirror, naked. He was a football player, so he was quite trained and muscular, but her eyes wandered down to the reflection of his cock. Limp, after just a few minutes inside his girlfriend. Small - tiny, to her eyes, compared to the monster she was wearing around her hips -- "12 inches -- 30 centimetres" the package had boasted, ready for international markets. Her brother didn't pack have half of that
He jumped as he noticed her in his room and turned round.
"Michelle? Whet the hell... can't you knock? I'm naked!"
He didn't bother to cover himself, despite his less than impressive cock.
"Why are you... wh... why the hell are YOU naked? Cover yourself, you're indecent. And why are you wearing that -- thing?"
He stared at her rubber cock like he only now noticed it.
"Is that supposed to be a Halloween costume? Are you dressing up as a guy? Gotta hide your titties then, sis. They're small, but not that small."
He chuckled. In Michelle's face not a muscle moved. He frowned at her.
"What are you... Say something sis, you're being weird. OK, it's Halloween, everyone's entitled to a good scare. You got me, now get the fuck out of..."
With a swift motion she pushed him backward, he smacked against the mirror, lost balance and fell to the floor.
"What the fuck..."
Tried to rise, but she was on him in an instant.
She should not have been able to push him down, let alone pin him to the floor. He was a head taller than her, muscular, trained. All but his small flaccid cock exuded strength and confidence. But she had done it. Because she could. Her muscles and sinews flexed, hardened as she grabbed his wrist, straddling his broad chest. He chuckled at first, tried half heartedly to push her off, wriggle his wrists out of her grip.
"OK. You're in trouble now sis, I'm gonna..."
He hesitated as his attempt to get rid of her failed. He doubled his efforts and then gave his all, his muscles bugled and he groaned. Her face remained motionless, her eyes, usually already dark, looked pitch black now. He gulped.
"That's enough get the fuck off of me, you bit..."
One of he hand clasped over his mouth, while the other took hold of both of his wrists above his head. He wriggled, struggled below her, to no avail. She moved downward, sliding over his belly, then her naked pussy slid onto his limp cock. Making it twitch, despite the scary situation, despite it being his sister's lips that touched it, his cock reacted like any typical primitive male would. Pathetic. And it was still tiny, even hardening..
She stared at him from he deep black eyes. He just stared back now, unable to say a word - this was not his little sister any more. There was viscous intent in these eyes. Evil. He was now more than scared. He was afraid.
Rightfully so. She slipped down from his cock and crouched between his legs. Let go of his wrists only to grab his hips in a vice like grip, He dug his nails into the floor, tried to wriggle himself out of her grip, but she held hum unrelentingly. She fixated his strong muscular thighs with her slender arms, had him right where she wanted him. Her face didn't betray any emotions over achieving her goal of rendering him helpless, cold and merciless she stared at him as she proceeded with her plan.
She didn't bother to lube her new cock. He will give in. One way or the other. As she put the head of her huge rubber dildo against his tight sphincter his eyes widened, he shook his head.
"What the fuck are you.. No. No!"
He jerked under her iron grasp around his thighs.
"Please. You're my little sister. Don't do this. That's sick... you cannnaaaaaa...!"
With a slow, but steady motion she pushed her hips forward moved into his asshole, spread it. It felt to him like it was tearing apart, but it was more flexible than he imagined. His sphincter gave in to the intruder, spread for it, allowed it to enter him inch by inch until it filled his rectum fully and stretched his hole wide. He let out a gargling sound, unable to vocalise refusal.
His sister stared down at him emotionless, her cock buried in his ass, remaining there for a few moments until she pulled back. And pushed back into him; in a steady, rhythmical movement she began to fuck her big brother's asshole, slower, then faster, and faster, harder, merciless. His gargling voice turned into moans and screams - and as his little cock actually grew harder from the stimulation of the huge cock inside his bowels, rubbing against his prostate again and again, the moans turning from painful and resisting, strained to lustful grunts. He stopped struggling, his wriggling became a twitching and writhing in the throws of lust as his whole body was flooded by a heat running through it from his stretched rectum. Suddenly he felt something rise inside his balls -- not the hot thick cream he usually extruded, but a thin, watery stream that erupted from his small, hard penis onto his ripped abs. It was not an orgasm as he was used to but it filled him with heat and shook his body. And still his sister was not done.
Other than his, her stamina was limitless - her fucking didn't end after five short minutes - for the better part of an hour she went on penetrating him, turning him into a quivering mass of flesh, squirting the thin cum from his little cock multiple times, only pulling out when she heard the car doors in the driveway. Their parents had returned from the Halloween Party of her father's company.
She slid out of her brother's ass, making him moan again. Unable to speak a word he tried to grab onto her, not wanting this to end, not wanting to let her go, but shook him off. He was too weak to hold anything and as she got up, he drifted into unconsciousness. He had learned his lesson. Time to teach her parents. She turned around, leaving her brother a quivering, moaning, fainted mess on the floor, covered in his own thin cum.
Left his room and stepped down the stairs, towards her loving parents As they closed the door behind them, her mother looked up and noticed her. Stared at her.
"M... Michelle? Michelle!"
Her father looked up, following his wife's gaze.
"Michelle., what the hell is gong on? What is this, why are you naked. What are you... where's your brother? What did you Do to your brother???"
