Amanda grinned as she peeked out the window, watching her mother's car disappear into the night. She let her curtain fall down and left her room, eager to put her plan into action. After all of her preparations, getting her mom tickets to a resort a state away, talking her aunt into going with her, convincing both of them that Amanda and her sister, Jenny, would be fine by themselves for a week (After all, Amanda was 20 and Jenny was 18. They didn't need a babysitter.)

On her way out, she stopped to look herself over in her full length mirror. She wore a black tank top, which hugged her body nicely. She ran a hand under her shirt and up her toned stomach, glad she had decent muscles without the full on abs, something that turned her off on a woman. Her hand continued on up to her modest b-cup tits, pinching a nipple. She also had on a pair of black basketball shorts, a size too large so the baggy fabric would hide a hard-on, but the waistband tightened so they didn't fall off. She wore no underwear underneath, her dick twitching against the shorts and her nipples clearly visible through the tank top.

Tonight was going to be perfect. She walked into the hallway and saw her sister coming towards her. Amanda smirked at Jenny as she passed her in the hallway. Jenny met her eyes and scowled, like she always did. Amanda couldn't help but notice Jenny's eyes glance downwards, towards Amanda's crotch, before brushing past her and entering the bathroom, the lock clicking.

Amanda had plenty of practice keeping herself from getting stiff around Jenny, since the younger girl had taken joy in calling her out on it ever since she learned what Amanda had that made her different from the other girls.

Walking into the living room, she sat down on the couch and turned on the TV. Her anticipation was replaced with anger for a moment. Memories of Jenny telling the kids in their school about Amanda's extra part fueled her rage, which had been building for years. Amanda let that anger burn, knowing this was the night she finally got her revenge.

Slipping her hand into her shorts pocket, she pulled a USB drive out and twirled it in her fingers, listening for the sound of the shower. Their house was nice, but some of the walls were thin. She turned the volume on the TV down low so even from there, she could hear the rushing water start as Jenny bathed.

Her heartbeat sped up as she waited a couple minutes, to make sure Jenny didn't come back out to get something she forgot. Quietly, Amanda stood up and tiptoed back towards her bedroom, passing the bathroom. She passed her own door and went to the end of the hallway, where Jenny had closed her door as she left it.

She opened her sister's door and went inside, glancing around. She rarely saw in here, since they hadn't gotten along in years. To be honest, the only reason they still spoke to each other at all was because Jenny was still a few months from graduation, and Amanda was taking classes at the local college.

Looking around, she quickly spotted Jenny's Xbox, hooked up to her tv. Amanda darted over and plugged the USB into the back of the Xbox. She grabbed the controller and turned the console on, turning the tv on before she sat down on her sister's bed.

She browsed through the menu and selected the USB drive, quickly opening the video she had put on it. She paused the video before the sound could start, and she sat the controller on her lap. She couldn't help but put a hand down her shorts and grabbing herself, instantly hardening, eager for Jenny to finish her shower.

Amanda didn't have to wait long. Jenny never took long in the shower. Soon enough, she heard the water shut off. She released a breath she hadn't realized she was holding. She could just just picture Jenny, stepping out of the shower and drying herself off with a towel, running the fabric over every nook and cranny...

Amanda was almost drooling at the thought, and jumped a little when the bathroom door opened. She pulled her hand out of her shorts, which hid her semi-erection, and picked up the controller. Jenny's footsteps came closer, until the door opened.

Jenny froze in the doorway, wearing nothing bu a towel around herself. Amanda had fantasized about that body, a foot shorter than her own 6 foot 2m and tits on the verge of being d-cups. The shock showed on her face, quickly becoming anger.

"The fuck are you doing in here, freak?!" Jenny yelled, and Amanda just smiled at her.

"Come on, sis, I just wanted to show you a video I found." Amanda hit play and the video started playing on the tv. Jenny ignored her, though.

"I don't give a fuck! Get the hell out of... my.. room..." Her yelling dropped off as she heard the video playing. Her eyes widened in realization and terror as she turned to her tv. Playing on the screen was an amateur video, clearly filmed on someone's phone. The video showed two people having sex on a bed, the girl moaning loudly.

Amanda didn't have to watch the video - she'd seen it enough times, had jerked off to it enough times. She just watched Jenny's face as she recognized her own voice in the video, watching herself take a stranger's dick. Another man entered the frame, and the angle changed, moving to look at her from the side as the second man took her in the ass. This new angle clearly showed Jenny's face.

Jenny moved quickly, shocking Amanda. The controller was ripped from her hands, and Jenny hit the power button. The sound died, leaving the two girls in silence. Amanda recovered, laughing.

"That must have been a wild birthday party your friend threw you, huh?" she asked, and Jenny gave her a death glare. She reached behind the Xbox, holding the towel in place with one hand and retrieving the USB with the other.

"If you tell anyone about this, you freak, I'll"

"You'll what?" Amanda interrupted her, instantly losing all the humor in her voice. Amanda started towards Jenny, who backed away from her until she was against the wall. Jenny's eyes widened as Amanda towered over her.

"You think that's the only copy I have? You think I don't have backups? Hell, I just need to go to that website again. So, what are you going to do to me?" Amanda stared her sister down. All of the humiliation she'd been put through by this little bitch had pushed her here, and she was ready to go all the way.

Jenny growled and slapped Amanda. The smack seemed to echo through the small room, and the two just stood there. Amanda slowly brought her eyes back to Jenny's, who seemed surprised by what she had just done, letting the USB drop to the floor.

"If you tell anyone, I'll-"

Jenny froze as Amanda's fist whipped by her head, putting a dent in the wall. Her jaw dropped as Amanda leaned in even closer, bring their noses together. Jenny started shaking as Amanda stared at her, no emotion showing on her face.

"I own you, Jen." Amanda whispered. "There's nothing you can do to me. Nobody will believe you. If mom sees that video, she'll kick you out. The kids at school know you're a stupid slut, and this will be the push they need to start treating you like one."

As Amanda spoke, Jenny paled, finally realizing the situation she was in. Amanda stepped back, giving Jenny a chance to recover.

"What... what do you want?" Jenny asked timidly. Amanda was furious, but she smiled, crossing her arms.

"Drop the towel."

Jenny looked at her, her eyes wide in disbelief.

"You don't mean-" Jenny was cut off again, but this time Amanda's hand hit her, taking the smaller girl in a light open palm slap across the cheek. Jenny cried out, covering her face with her hands.

Jenny shrunk back a little more, as Amanda growled at her.

"Drop. The. Towel." Jenny slowly let her hand fall from her face, and obeyed, giving the towel a quick yank. It fell to the ground, exposing her body to Amanda's gaze. She couldn't help but lick her lips as she looked her sister over.

Jenny was almost her opposite, slender and frail looking, with pale skin, a stark contrast to her own tanned flesh. Amanda slowly reached out, making Jenny flinch, and flicked one of the little metal hoopes that were pierced through her nipples.

"Damn, only 18 for a couple months and you've already got piercings. Gotta say, Jen, I'm liking them." Amanda grabbed Jenny by the shoulder and pulled her forwards. Jenny yelped as she was pulled away from the wall.

Amanda walked a circle around her, taking in the view from every angle. She chuckled as Jenny tried to hide her pussy and tits with her hands. Moving quickly, Amanda snatched Jenny's wrist, exposing the girl's shaved pussy, and gave Jenny another light slap.

She didn't yelp this time, just flinching in shock. Tears started to form, running down her face. Amanda pulled Jenny in close, leaning down to lick a tear off of Jenny's cheek.

"Don't worry baby sister, I won't hurt you." Jenny said, wrapping her naked sister in her arms. She made sure to press her hard-on against her sister, who tensed when she realized what it was.

"I just need to teach you a few lessons, baby. When I'm done, you'll be so happy to be with me." Jenny started crying now, as Amanda let her go and stepped back. Amanda stripped quickly,pulling the tanktop over her head and dropping it on the floor, quickly followed by her shorts. Now they both naked, and Jenny gasped at the size of the dick now pointed in her direction.

Amanda was never one to brag, but she was confident in her 10 inches. She'd heard her father and mother arguing about it, once, before the drunk had left them. She was 18 when she overheard the man complaining because her's was bigger. She knew her mother loved her, but also blamed her for tha man's loss in confidence.

Pushing those thoughts away, she put her hands on Jenny's shoulders. She pushed the girl down onto her knees, and Jenny whined as Amanda's dick slapped her cheek. Amanda put her hand on Jenny's head.

"Suck." She ordered, and Jenny needed another slap before she started, slowly licking the tip before beginning to take it into her mouth. Amanda moaned as Jenny worked. She could tell when the smaller girl finally gave in, working her tongue and taking the shaft as she could go.

Jenny's head bobbed back and forth, and Amanda put her other hand on Jenny's head. In one quick thrust, Amanda slammed her hips forward and pulled Jenny's head towards her, gagging the girl as she came.

Amanda's dick shot ropes of cum into Jenny's mouth, going straight down the girl's throat. She pulled out in the middle of one rope, leaving a decent amount in her mouth, and as her dick came free with a wet pop, she shot another one in Jenny's face, coating the girl in sticky cum.

Jenny shrieked as this happened, falling backwards without Amanda's hands to hold her in place. Amanda sighed in content, stepping back and sitting down on the edge of the bed. Her head fell back as she stroked herself, drawing forth another shot of cum, which landed on Jenny's sprawled leg.

They stayed there in silence for a few minutes, Amanda's cock slowly softening. She watched Jenny grimace at the taste in her mouth, swallowing the leftover cum so she didn't have to clean it up off the floor. Jenny's eyes met her sister's.

"You got what you wanted. Get out." She said hoarsely. Amanda chuckled, and fell backwards onto Jenny's bed. She took a deep sniff of the blanket, which was soaked in the scent of Jenny's favorite perfume, some fancy strawberry scent.

"Oh, Jenny, I'm not done with you yet." She stared at the ceiling, knowing her sister was still staring at her - or more likely, from her angle on the floor, at her dick, which was slowly starting to grow again.

"But you're almost right. I will get what I want." Amanda sat up, looking at Jenny with an eveil grin on her face. Amanda stood up, and motioned for Jenny to do the same. Jenny did, and Amanda took her sister's hand, leading her out of the bedroom and towards her own.

Jenny resisted a little, but Amanda was more than strong enough to pull her along. She dragged Jenny into her room and shut the door behind them. Leaving Jenny standing at the door, Amanda got down on one knee in front of her bed and reached underneath it.

Her hand wrapped around what she had hidden there, and she pulled it out and stood up. Jenny gasped as she saw the collar in Amanda's hand, shaking her head. Jenny turned to leave, but Amanda was there, her free hand holding the door shut and using her body to hold Jenny against the wood, her dick resting against Jenny's lower back.

"Either you do as you're told, or that video goes to everyone you know. Either way, I'm getting what I want tonight Jenny." Amanda wrapped her arm around Jenny's waist as she slid the leather collar around Jenny's neck.

Her hand slowly wandered up Jenny's stomach, tracing a nipple and giving the piercing a tug, before taking the other end of the collar. She clicked the ends together, the latch hidden behind the small metal heart which now rested snugly against Jenny's neck.

Jenny sob made Amanda even more excited. She picked the girl up by the waist, making her shriek. She took the couple steps to her bed and threw Jenny down face first into the mattress. Climbing on top of her, Amanda laughed.

"Come on Jen, don't cry! I know you love taking dick, so just enjoy yourself! After all, you'll be getting a lot of mine this week." Amanda picked Jenny up a little so she could position the tip of her dick against Jenny's slit. Amanda bit back a moan at the sensation.

"See? You're soaking wet, sis. You can take my dick easily." Jenny whimpered as Amanda thrusted forward a little bit, spreading Jenny open. Inch by inch, Amanda sunk her cock into her little sister, whose whimpering was starting to become moaning. With one last thrust, she was all the way in.

"See?" Amanda asked, putting a hand around Jenny's throat and pulling her backwards.

"Your slutty little pussy was made for my dick, Jenny." Amanda started fucking her, pulling halfway out and slamming back in, making Jenny moan. Her thrusts picked up speed as she railed Jenny with all of her might.

"All that teasing... that tormenting." Amanda grunted, letting her grip on her sister's throat go and grabbing a fistful of Jenny's silky black hair. She yanked the girls head back, and Jenny moan became a scream.

"All for this, baby..." Jenny's screams became louder as Amanda fucked her like an animal. The dick inside her was reaching deeper than any other she'd had.

Amanda's other hand swung back and delivered a sharp smack to Jenny's ass.

"You're my slut, Jenny!" Amanda barked, and Jenny was too lost in bliss to say anything back.

"My stupid," smack "little" smack " cocksleeve!" With one final thrust, pulled Jenny up almost into a sitting position and Amanda let loose her second load inside Jenny's sore cunt. Jenny came as well, her own orgasm triggered by the feel of Amanda's cum filling her up.

She shot rope after rope of cum into her sister's cunt, and when she was finally spent, Amanda let Jenny fall forward. The girl's face hit the bed, too tired to catch herself. Amanda collapsed on top of her, and the girls laid there for what seemed like forever.

After a while, Amanda recovered enough to shift them into a more comfortable position. Taking care not to dislodge her cock from Jenny's pussy, she laid on her side and started spooning Jenny. The younger girl was too tired to resist, letting herself be pulled into the embrace.

Amanda's hand wandered to Jenny's tits, gently playing with the girl's nipples, and she started whispering to her sister.

"See? That was amazing, Jenny. You're a great little cocksleeve. I'm gonna train you so mine is the only dick you'll ever want, baby." Jenny just nodded, her sister's words sinking in. The terror was long gone, replaced with the pleasure of her sister's dick, and the anticipation of getting it again.

"I'm gonna fill you up with my cum every day, and when mom's back I'm gonna take you while she sleeps, and while she showers, and while she works..." Jenny just moaned in response, and Amanda smiled.

"What are you, Jenny?" Amanda asked, giving her sister nipple a sharp twist. Jenny cried out, and Amanda's dick stiffened again.

"I'm... your cocksleeve." Jenny said between moans, and Amanda laughed. Yeah, this night was perfect.
