Trained Step Sister pt.1

Allison came home from school to an unwelcome surprise. Her step brother Mark had returned home for the summer from college. Their parents had gotten married when she was fourteen and he was fifteen. He always struck her as a bit of a creep. As she went through puberty, she could tell he was always checking her out. She had blossomed into a lovely young woman, big full breasts, a tight ass, and a tiny waist was set off with pale blonde hair and big blue eyes.
Summers were the worst, she would be out by the pool in her bikini, and he would come out and try to talk to her, all the while ogling her tight young body. It got to the stage that she would instead go to friends houses to avoid being around him.
She had tried to explain things to her mom, but she had just brushed it off as an over-reaction.
Once he graduated and left for college, it was a lot more comfortable around the house. Now he was back for the summer. Great.

As she walked into the house, he was seated on the couch, watching tv and drinking a beer. She snorted.
“It’s not even 2 in the afternoon, and you’re already drinking?”
He turned his head in her direction. “It’s how we do in college.”
“Yeah, if you can find someone to buy for you. You aren’t even legal yet.”
He smiled. “It don’t matter, it’s college.”
“And if mom and dad find out that you’re drinking their beer?”
He chortled. “They won’t know. It’s from the fridge in the garage, it’s been there since Christmas, they’ll never even realize it’s gone.”
“They will if I tell them.”
He cast her a sidelong glance. “Naw, you’re cool, you won’t rat me out.”
She was overpowered by the stench of stale beer. It practically radiated off of him.
“Jesus, you smell like a brewery!!! How much have you had?”
He cocked his head to the side. “Maybe two or three…”
“Bullshit! You’re fuckin’ drunk!!!”
“C’mon Allison, don’t be like that, it’s cool….”
“No it’s not! I come home from school to find you drunk in the middle of the day!! It’s so ….. cheesy!!!!”
He laughed at her indignation.
“You’re such a tight ass. You need to loosen up.”
“Fuck you!!”
His eyes narrowed.
“You shouldn’t talk like that, your mouth is going to get you in trouble.”
“Oh, like you’re gonna fuckin’ do something!” She rolled her eyes. “You’re pathetic!!”
Mark glared at her. She always thought that she was too good for him, ever since she was a kid.
Prancing around in her string bikini, flaunting herself in front of him, then acting all offended when he would look at her.
Fucking bitch. Fucking tease.
He would fix her.
He pulled his hand back and slapped her across the face. Not hard, he didn’t want to hurt her, but enough to let her know to knock off the attitude.
Her eyes widened and she flung herself at him, flailing her fists around. She caught him right beneath the eye with a punch while screaming insults at him. He grabbed her arms and spun her around, wrapping her up. She flailed around as he held her tight against himself. His crotch was pressed right up against her ass, and the way she was wriggling around started to give him an erection.
He had always been horny for his step sister, even though he knew it was a little twisted, and this wrestling match was getting him aroused.
He turned and shoved her face down into the couch, wrapping his hand around her wrists and pinning them above her head.
“You’ve been a bad girl Allison, and I’m going to teach you a lesson.”
“Fuck you!!” She screamed at him.
“You’re only making it worse for yourself, you know.”
He knelt beside her, driving his shin across the backs of her calves, pinning her legs in place.
She was now trapped face down, against the couch.
She wriggled to no avail.
“Mark, this isn’t funny, let me up.”
“Nope, not until you’ve learned your lesson.”
He took his free hand and brought it down, open palmed against her ass, hard.
She let out a howl, and renewed her efforts to break free.
He brought his hand down again and again, bringing tears to her eyes.
“Mark!!! What the fuck is wrong with you?!?!? I’m going to cut your fucking balls off!!!”
He shook his head.
“You just keep digging yourself in deeper and deeper, don’t you Allison?”
He reached for the waistband of her shorts and wrestled them down to her knees.
Her white thong panties contrasted nicely with her bright red ass cheeks.
She screamed.
“Mark, what the fuck!!!!?????!????”
“Is this how you dress for school, you little tramp? Do you like to tease the boys, or do you put out?”
“Are you fucking crazy, you’re going to die for this!!!!”
“What are you Allison, a tease or a whore?”
“Fuck you!!!”
He hooked the waistband of her panties and pulled them down to her knees as well.
She screamed in revulsion.
“Let me up, you dirty perv!!!”
He peered down at her pussy.
“You aren’t a virgin, are you Allison? You slut.”
She shuddered. This was way beyond weird, this was seriously scary. The next thing she heard terrified her. It was the sound of a zipper being undone.
“Mark…..” her voice quavered. “What do you think that you’re doing?”
“What I’ve been wanting to do since our parents got married.”
She trembled. She always knew that he was a pervert, but it never crossed her mind that he would actually rape her.
Their parents were at work, and never got home before six.
No one could hear her, their house sat on a large lot.
She felt his weight shift, then her legs were free.
Before she could move, his knees were pinning each of her legs down. He was now directly behind her, running his dick up and down her slit.
She began crying.
“Mark, please don’t do this. You can’t, you’re my brother.”
“Step-brother.” He corrected.
As he continued rubbing his engorged dick head up and down her pussy, he could feel her starting to get wet.
“You’re enjoying this Allison, you’re getting wet. You want this.”
She shook her head no, repulsed by the idea, but she was aware that her pussy was lubricating itself.
Her mind was rebelling, but her body was responding.
Mark continued rubbing up and down her slit, getting his cockhead nice and wet.
“How many guys have you fucked, your pussy feels loose.”
Allison burned at this. Alright, she wasn’t a virgin, but she also wasn’t a slut.
“How many guys have you fucked?”
“Five.” Allison responded.
Mark nodded. “You had a couple of boyfriends, I know you fucked them.”
Allison nodded.
“Who else?”
“Just a couple of guys at parties.”
Allison felt him starting to probe at her pussy opening.
“How old were you when you lost your virginity?”
Allison blushed. “Fifteen. It was to Jack.”
“Your first boyfriend.” Mark popped the head of his dick into her, and Allison gasped. She hadn’t seen his dick, but he felt larger than the boys she had been with.
“When was the last time you had sex?”
“Fourth months. When I broke up with Chase.”
Mark nodded. He rocked back and forth a bit, pushing halfway into her.
“I want you to remember this Allison. If I’m number six, then I’m not really special. So I think I’ll try something else.”
He withdrew from her pussy and eyed her asshole. He doubted that anyone had fucked her there.
Well, there was a first time for everything.
He placed his dickhead against her asshole, and Allison began panicking.
“Wait, what are you doing??? No, no!!!!! Not there, oh God, Mark!!!!”
Keeping her hands pinned down, Mark began forcing himself into her asshole. At first, he couldn’t budge through, and began to wonder if it was going to work, then his head popped though the tight muscle.
Allison screamed loud enough to bring the house down.
Mark took his free hand and smacked her ass.
“Quiet, you make too much noise.”
Allison began sobbing.
“Oh my God, nonononono!!!!!! Please take it out, it hurts!!!”
“You’re just going to have to take it Allison, you shouldn’t have been such a little bitch.”
He forced Allison to inch forward, resting her face on the back of the overstuffed couch.
“Bite down on the cushion.”
He released her hands and placed both of his hands on her shoulders.
Allison was in too much pain to try and fight back, she grabbed the cushion so tight that her knuckles turned white.
Mark grunted and shoved forward, while pulling back on Allison’s shoulders.
“Nnnnnooooooooooooooo!!!!!!!!!” Allison screamed as he forced half of his dick up her ass. She bit down on the cushion like he told her, and moaned loudly into it.
“Ooooooohhhhhhhhhh!!!!!! Uhhhhhhnnnnnnnn!!!!!!”
Mark kept his hands on her shoulders, and pulled back out a bit before slamming back into her ass again.
“Uuuuhhhh!! Uuuuhhhh!! Uuuuhhhh!!” Allison kept grunting as Mark hammered into her ass. Tears were streaming down her face as she endured the painful ordeal. He had lost his fucking mind; she was so going to make sure that he paid for this.
As Mark continued plundering her ass, Allison began to realize that she was getting hot. She couldn’t believe it. Was she getting turned on by this rape?
Her body was responding, she could feel her pussy juicing up, and her hips began bucking of their own accord.
Mark leered at her.
“I knew you were a fucking slut, look at you starting to get into this. I should have done this a long time ago, it would have straightened your attitude out.”
Allison blushed a deep crimson.
She knew this was wrong, she knew he was a pervert, she knew that she could never tell anyone this, but…..
The way he was taking her, the way he had forced himself on her, the feeling of helplessness…. It was exciting to her.
She whimpered. “Please …. It hurts.”
But even the pain was a turn on, the way it mixed with her pleasure, it was an exquisite feeling.
His rock hard cock was pulsing in her ass, signaling that he was about to cum.
As loathe as she was to admit it, Allison wanted this to continue.
She reached down between her legs and began to rub her clit. If Mark was going to finish, then she wanted to get off before he did.
He saw her movement, and it re-invigorated him.
He grabbed her hair and roughly pulled her back, wrapping his arm around her neck, holding her in place.
“You want to cum from your ass fucking, don’t you Allison? Say it!”
“I want to cum…..”
“Like a dirty whore….. Say it!!!”
Allison hesitated.
Mark twisted his hand in her hair, causing her to cry out, and pulled hard against her windpipe.
“Say it!!!!”
“Like a dirty whore…..”
Mark sighed with contentment and shoved her head back into the couch.
He grasped her hips in his hands and drove his dick as far and as hard as he could into her ass, making her scream again.
“You’re a whore Allison, you’re my whore.”
“I’m your whore…..” Allison whispered, totally defeated.
Mark was surprised; he hadn’t expected her to repeat what he had just said, but it thrilled him. She was surrendering herself to him.
He began spurting his cum deep into her bowels, gasping for breathe as he did so.
Allison moaned as she climaxed, her sphincter clamping down on his dick.
Mark gasped as he felt the pressure. Jesus, he thought that her ass had been tight before…
He collapsed on top of her back, and lay there trying to collect himself.
He pulled his spent dick from her ass as gently as he could.
She remained face down, not turning to face him.
Mark sat silently for a few moments. He had been caught up in his lust, but now reality was washing over him.
He had raped his step-sister.
Yeah, she might have cum from it, but he had started it, forced her down, pulled off her shorts, then violated her asshole. He could hear her crying softly.
He stood and left, climbing into his car and driving off.
Allison lay on the couch for another several minutes before she pushed herself up.
Her ass felt like it was on fire. She was sure that she was torn and bleeding down there. She was in a state of utter confusion.
While it had been happening, she had been so aroused by the feeling of being taken that way, but now that it was over, she was revolted by the thought of being sodomized by her brother.
Step-brother, she reminded herself.
It wasn’t really incest, even if it was ….. gross.

She went to her bathroom and climbed into the shower. As the water cascaded down her body, she began tracing her hands over herself, reliving what had just happened to her. She reached for her clit and began gently stroking it.
The feeling of helplessness had been a turn on, the sense of not being in control.
All the guys she had dated had been kind of timid, always asking her permission before they did anything.
A couple of the jocks had just assumed that she would put out for them, and that hadn’t done much for her.
Her boyfriends had satisfied her, but they were always so … careful.
Trying not to make her mad.
Her looks had always gotten her whatever she wanted, but they had also made guys treat her like a goddess, always acting extra careful with her, so as not to make her mad.
Even when having sex, the guys had been asking her if she was okay, if it felt good, if they needed to be doing anything different.
They were so solicitous, it had gotten on her nerves.
She had to tell Chase, her last boyfriend, just to shut up and fuck her, but he had always gone back to his simpering nature, trying to please her.
