Chapter Three: Breakup
Sasha’s mother was happy to surrender the money her daughter needed, in exchange for Sasha taking the cars to get washed. It took two trips in order to do it, but that part wasn’t important. Only the money was important. Only the tape.
On her second trip back, with her mind on her cunt, Sasha passed by the soccer field for the college campus. It was the college that Megan and Mark attended, and the same one that Sasha was planning to go to at the end of summer. It was a reflexive thing to look over at the field. Sasha’s hatred of Megan was always there, and catching a glimpse of the bitch just kept the hatred hot.
Sasha slowed as she passed the field and scanned the players coming out of the gate. There she was. Fucking Megan and her petite little tits, wearing a soccer jersey and shorts. Sasha pulled to the curb to watch the stupid cunt, imagining those lean, muscular legs wrapped around Mark’s waist.
Megan wasn’t alone, though. There was a guy with her, a hunky one. Not like Mark. No one was like Mark. But the guy was hot. He put his arm around Megan and leaned in to kiss her neck.
Sasha gasped. Was Megan seeing someone else? Was she cheating? That… that cunt! Cheating on Mark? Her skin burned at the idea that this ungrateful tramp with her little tits and sculpted ass would even consider such a thing. She had the perfect man, and here she was with some fucking loser’s arm around her waist and lips on her neck, like she belonged to him.
Sasha put her hand on the door handle, then stopped. No. Confronting her here wouldn’t do. But there was one thing. She pulled out her phone and quickly opened the camera, then zoomed in and hit record. Megan giggled on the camera and stopped walking. She turned to the guy and leaned up to kiss him on the mouth. Their hands touched, lingered, and then he let her go. They parted.
Sasha quickly turned off the recording and drove away before Megan could spot her. Her stomach lurched. She should tell Mark, expose Megan’s treachery. How, though? The thought of his pain and humiliation was the weight of a cross. If she told him, she’d be responsible.
She agonized over it all the way home, and by the time she pulled into the driveway, she had a plan. But there was something else to handle first. With thirty-five dollars from her mother, she went out to the ATM and made the deposit. Now she had it all.
Sasha’s hands were sweaty and her heart raced as she pulled up the browser and opened the bookmark for the tapes. Her hands shook so much that she could barely type in her information. There was no hesitation when she placed the order. Once she had, though, a new screen appeared.
“Customize your Rape Tape,” the message read, and a red button prompted her to begin.
Sasha glanced at the door, went and locked it, then returned to the chair. She rubbed her bare, wet pussy and clicked the red button.
“Enter your first name,” the screen prompted.
Sasha.
“Do you have a fixation on a particular individual?”
Yes.
“What is the individual’s name?”
Mark.
“What is your relationship with Mark?”
Brother.
Just typing the word made her pause to push her fingers into her warm cunt. She’d told Rape Tape the secret. They knew that she wanted the tape to train herself for her own brother. Slut. Dirty, perverted little slut.
“As best you can, describe your desired outcome.”
Sasha knew the outcome well. How did she put it into words, though? It was mostly fantastical images in her head. Mark pushing his tongue into her mouth. Mark holding her hair and guiding her mouth to his cock, telling her she was his precious pet, his perfect sex doll. Mark thrusting into her depths as she lay prone, her fists wrapped in the sheets as he whispered hotly into her ear that her pussy was made for him.
Every filthy fantasy she had flashed like a movie montage through her mind as her sticky fingers probed her pussy. She just needed to put it into words. She needed to type the dark secrets into the computer, give them to a stranger, and she could have it come true. With an effort, she pulled her wet fingers from her cunt and typed.
I love him. I don’t know if he feels the same, but I want to be for him. I need to be everything he wants. His pet. His dirty slut. I want to be made for him, to belong to him, to have him fuck and use me at his whim. Every fantasy, every want, every desire that he has, I want to fulfill. I want to be his perfect slave and have his will become my own.
If he wants to slap me, I want it. If he wants to share me or show me off, I want to want it. When he needs a warm hole to pleasure himself, I want to be that for him. Make me his brainless fucktoy.
She hit send before she could think about the words she’d typed. A green checkmark appeared, followed by a new prompt.
“Click to continue when you have a microphone attached.”
Sasha put on her headset and flipped down the microphone, then pressed the button.
“This process will take approximately thirty minutes. You will repeat the words on the screen. Click to begin.”
Sasha clicked the button and began to repeat the words.
“Pussywillow. Comeuppance. Fuck. Continue. Cream. Grape.”
The words went on, seemingly randomly, and by the time Sasha finished, she still didn’t understand the purpose. When the checkmark appeared again, the final screen appeared.
“Thank you for your order. We are processing the information. Your product will be expedited to the address you supplied. A tracking number will be sent to the email address you provided within twelve hours.”
The screen went blank and then returned to the main page. A moment later, an email appeared from Mega Mix Tapes. Transform yourself through the power of music! The sender was RTOrders@DomCo.MMT.com.
The temptation to just give in and continue rubbing her twat was strong, but there was still the problem of Megan to attend to. She shoved her fantasies aside and downloaded the video file from her phone. Using a VPN and a new email address, she attached the video to an email and typed in Mark’s address. Her finger hovered over the send button.
This would hurt her brother. It would also let him know the truth. Megan was a slutty, stupid, cheating cunt. She didn’t deserve him. Sasha deserved him. A moment of pain, followed by so many moments of pleasure. If she could just admit the truth to him.
The truth, though, was frightening. She didn’t know if Mark liked the things she liked. Did Mark ever look at her and fantasize? Did he want to do things with her? Would he use the tape on her? She pressed the button.
***
At dinner that night, Mark showed no sign of having read the email. Sasha kept her eyes down on her plate, nervousness knotting her stomach. Would he know, somehow, that it was her that had sent the video?
Their parents were talking, discussing their upcoming trip to Europe. For the rest of the month, they’d be away, leaving her alone with Mark. But that was still days from now.
The implications of her plan hung heavy in her mind, adding to the worry, but the obsession was stronger.
Sick little pervert slut.
If Mark used the tape, and it worked, what would she be like after?
She’d watched the video of Mallory and her brother dozens of times now, but there was never any mention of what Mallory’s day-to-day life was like after the tape. Was she her normal self most of the time? Would there be a compulsion, a trigger, like a hypnotic compulsion that turned her from normal Sasha to slutty Sasha?
There is no normal Sasha, you dumb slut. Normal girls don’t want the things you want. You’re a fucking pervert. A sick, stupid, slutty pervert.
Her hand strayed toward her cunt, but she stopped herself. Mark smiled across the table and she practically melted in her seat. She actually let out a little moan and he quirked an eyebrow curiously. Sasha blushed and looked at her plate again.
“You thought about what kind of car you’re getting, honey?” her mother asked.
“What?” Sasha asked, snapping her head up. “Oh. No. Not yet. I’ll just wait until I see the right thing.”
Her father nodded and said, “Just land a part-time gig first, so you can handle the payments.”
“Thanks, Dad. I will.”
“Any leads?”
Sasha shook her head. A job was the last thing on her mind right now. What kind of job would Mark get after he graduated? He might move out. Would he take her with him? The thought was another frightening one.
She glanced across the table, where Mark was scrolling through his phone. Sasha’s heart stopped. She held her breath, her fork trembling in her hand, poised above her plate. Mark’s brows furrowed, and he tapped at the screen.
For a few seconds, he watched the screen, his expression darkening. He’d found the video. It had to be. Mark tapped the screen again, cleared his throat, and picked up his plate. Without a word, he took it to the trash, then stalked out of the room.
“He okay?” their mother asked.
Their father shrugged.
Sasha said, “I’ll go check on him.”
She pushed her plate away and shoved the chair back, a little too hurriedly, but her mind was moving a mile a second. Once she was out of the kitchen, she hurried to catch her brother. He was halfway up the stairs as she followed.
“Mark,” she hissed, and he stopped.
When he turned, there was anger in his eyes, and hurt that broke her heart and made it soar at the same time. He knew Megan was a cheating skank. He knew, and he was hating her right now. Sasha bounded up the steps.
“You okay? What is it?” she asked.
Mark looked toward his bedroom door and said, “Nothing.”
He turned to go, but Sasha caught his arm.
“You can tell me,” she said and looked into his eyes, projecting all the sympathy she could muster.
Mark sighed and said, “Come on.”
Sasha followed him to his room, where he shut the door and sat on the bed. He swiped open the phone, tapped, and handed it to her. Sasha took it, played the video, and feigned shock.
“Oh, shit! That… that cunt! For real?”
“Looks that way,” Mark grumbled. “Cunt is right. Fuck. I treated her like gold, too.”
Sasha sat next to him and handed back the phone.
“You did,” she said and touched his arm.
The heat of him made her cunt hot.
“I don’t get it,” he said. “The whole nice guy thing works for a while, and then? What the fuck? What is it with women?”
Sasha shook her head and said, “She doesn’t know what she’s giving up. Some girls just aren’t in it for the long haul, you know?”
“Yeah, I guess. Or maybe I’m just missing something.”
“From what I hear through that wall, you’re hitting a lot more than you’re missing,” Sasha said and then clapped her hand over her mouth.
Had she actually said that? Mark quirked a brow, then reddened.
“Shit! I should have known you could hear that crap. I’m so sorry. I didn’t even think… you must think I’m some kind of pervert.”
Sasha shrugged, her pussy hot, and she said, “No more so than the rest of us.”
It was a lie. She was worse. So much worse. Disgusting slut. Brother-lusting pervert.
Mark laughed and said, “Right. You’ve been with, like, one dude. Trust me, the shit in my head would make you look like a nun.”
“Are we comparing now?” Sasha asked.
Her hand was clammy on his wrist as she asked the question. Was this really happening? Did she actually suggest that they should tell each other their sexual fantasies? Mark didn’t look at her like a weirdo. He grinned.
“You don’t want to know what your big brother thinks about,” he said, and his hand covered hers.
Sasha bit her lip. Her cheeks burned and her head was light, buzzing with excitement as her fantasies began to spin out of control. She should stop. If she opened her mouth, she’d say something slutty and then Mark would know. He’d know the secret, her obsession, and then he’d… she didn’t know.
“Maybe I can guess from, you know, what I’ve heard.”
“Why would you want to guess?” he asked and glanced at the door.
Sasha followed his gaze. She stood up, adjusted her little shorts for effect, and went to the door. The lock clicked. She returned and lay on the bed, then patted the space next to her. Mark eyed her suspiciously, but a smile played at his lips as he lay next to her.
“Call it… something to take your mind off that bitch,” Sasha said. “Like a game.”
“I like games. What kind of game?”
Sasha thought a moment, then said, “No judgment. I tell you one thing that I think makes me a bigger pervert than you. You tell me if you’ve thought of something dirtier.”
“Okay? What’s the point of this game?”
His eyes flicked to her cleavage, and Sasha suppressed a moan.
“To prove which of us is the bigger pervert, of course.”
“Maybe I’m not getting it. Why do you want to know which of us is the bigger perv?”
“I don’t want to know,“ she lied. “It’s just a way to get you to stop thinking about her and think about something fun. What’s more fun for dudes than fantasizing about sexy stuff?”
“Doing sexy stuff?” Mark suggested.
“Okay, yes. Doing sexy stuff. But guys stop thinking about what’s bothering them when they’re thinking about sex, and that’s the point.”
“And girls?”
Sasha shrugged and said, “Yeah. It works for us, too, mostly. Are we going to play or not?”
“You’re serious?”
“Serious as a limp dick at an orgy.”
Mark laughed and said, “That’s pretty serious.”
“Okay. I’ll go first,” Sasha said. “Giving blowjobs to your friends.”
Mark’s brows furrowed and he asked, “You think about giving my friends blowjobs?”
I think about you making me blow your friends
“Sometimes?” she said aloud.
“Okay. That’s not really that perverted,” Mark said. “Try this. I think about Megan giving my friends blowjobs, while I make her wear a leash and collar.”
Sasha’s face reddened with arousal, which Mark mistook for offense, and he said, “Too much?”
Sasha blew out a breath and shook her head, saying, “No. That’s… that’s really hot.”
“Does that mean I’m the bigger pervert?” Mark asked.
“That was only the first one. You wanna keep going?”
Mark motioned for her to continue.
“I… sometimes… I play with myself when I listen to you and Megan fuck.”
Mark’s eyes bugged and his mouth worked.
“Damn,” he whispered. “For real?”
“Just sometimes,” she said.
Every fucking time.
“Okay. That’s pretty hot, too. But again, not all that perverted. I jerked off to Mom and Dad fucking once.”
Sasha giggled and said, “So did I!”
“I’m beginning to like this game. Why haven’t we played this before?”
“You’re too busy fucking Megan to notice me?” Sasha suggested and bit her lip in what she hoped was cute.
“No way. Sasha, do you really think I’m, like, neglecting you or something?”
“No,” Sasha said and shook her head. “It’s just, since she started coming around I don’t get to see you as much. We used to do stuff, but now you spend your time at school or with her. I guess I just kind of miss it. Sometimes.”
“Uh, well, I’m guessing spending time with Megan is sort of off my agenda now. Shit. I should probably call her and tell her it’s over.”
“So, you’re done? Just like that?”
“Oh! No. I was getting into this. Let’s keep going. That bitch can wait,” Mark said.
Sasha’s heart hammered.
That bitch. That cunt.
“Your turn,” she said and swallowed a lump in her throat.
“Alright. I’m gonna win with this one.”
“Winning means you’re the biggest pervert, remember?” Sasha reminded him.
“Um, yeah. No Judgment, right?”
“No judgment.”
Mark nodded and said, “I fantasize about having a sex slave. Like, a real one. A hot girl that loves being told what to do.”
Sasha almost drooled but shut her mouth and clenched her fists.
“Was Megan into it?” she asked.
Mark shrugged and said, “Not like that. I mean, we did some kinky stuff, I guess. Blindfold, some of those fuzzy handcuffs. You know, that shit. But she wasn’t really into it. No. I’m talking about the real deal. Someday, I want to find a chick who’s really into it.”
Sasha looked away, her cheeks flushed and a sheen of sweat shining on her skin.
“You okay?” Mark asked. “You look a little warm.”
“Mark,” she whispered. “Do you really think that? Like, really, really, for real?”
“The sex slave thing? I guess so. I think most guys want that to some degree. Who wouldn’t?”
He chuckled, but it died quickly and his look turned to one of concern.
“What? Is that too much? Shit! I shouldn’t have said that, Sasha. I’m sorry. Can you just forget about it?”
“It’s not that,” she said. “It’s… can I show you something?”
“Okay?”
She slid from the bed and said, “Come in my room.”
Mark followed. Sasha opened the door, feeling as if she was floating down the hall to her room.
I’m going to show him. He’s going to know. Oh, fuck! He’s going to know. Fucking slut. Horny pervert. Depraved little bitch.
She opened the door, looked both ways down the hall, and then nodded for Mark to follow. Mark shut the door. Sasha turned on the monitor and sat in the chair. Her hand shook so much that she could barely move the mouse.
“Sasha, you okay?” Mark asked.
“I just… I want to show you,” she said. “And I don’t think you’re going to win the game.”
“I’m intrigued.”
Sasha opened the browser and clicked the bookmark on her bar for the Mallory videos. The page loaded. There was no going back. She clicked the play button on the video.
Mark stood silently behind her as the video of Mallory played. The girl in the video, collared on her knees before her brother, repeated the lines that the tape had placed in her head.
“My mouth is a wet hole for my brother to fuck.”
Mark whispered, “Holy shit. Is this, like, the real deal?”
“I don’t know,” Sasha admitted. “But it seems like it.”
Mark turned the chair around, forcing his sister to face him. Sasha lowered her eyes, refusing to meet his. He cupped her chin and she trembled. The touch was exactly what she’d dreamed of. It was gentle but dominant, and when Mark tilted her head up, Sasha couldn’t resist.
She met his eyes and Mark asked, “Is this what you watch? This is what you like?”
“Yes,” Sasha whispered. “I… I like it.”
“Do you touch your cunt when you watch this?”
Sasha whimpered and said, “Yes.”
“You still haven’t won the game,” Mark said and smiled.
“No?”
“You think a little incest porn makes you the bigger pervert?”
Sasha couldn’t help but grin as she said, “Incest sex slave porn.”
“I think I have a better game,” Mark said and his thumb slid across her chin and touched her lower lip. “Tell me about the tape in that video.”
Sasha’s tongue flicked out to lick at his finger. He pushed the thumb into her mouth and his sister’s lips closed around it. He grinned as she sucked at it, then pulled it away and repeated, “The tape.”
“It’s called Rape Tape,” she whispered. “And I can do better than tell you.”
“Oh?”
“I… I bought one,” she said.
“You bought one? Why?”
“I… I wanted to see if it was, you know, real.”
“How, if I may ask, did you plan on testing its authenticity?”
Sasha’s cunt was hot and in control. She’d let Mark into her fantasy, taken that first step, and he hadn’t rejected her. The opposite. He was playing along. Would he be willing to play further? She had to know.
Pervert Slut. Hot-cunted whore.
“I wanted to—“
She reached out a hand and put it on Mark’s chest, then looked up.
“I wanted you to do it with me.”
Something in his eyes went dark and cold as he stared back down at her. A smile spread across his lips, but it was not a kind one. There was menace and evil in that smile, like watching a vampire toy with its next meal.
“Then I think you’ll like my new game,” he said and put his hand over hers. “Do you really want to know which of us is the bigger pervert?”
Sasha’s eyes flicked down to his crotch, where his cock was outlined in his shorts.
“Yes,” she whispered.
Mark moved her hand to the waistband of his shorts. He slid his hand along her cheek, cupping the back of her head and curling her blonde hair into his fist. He tugged gently, forcing her eyes up.
“What is your mouth for, Sasha?”
Sasha’s pussy practically gushed as he said the words. It had just become real. Every dream, every fantasy, the long nights of wishing as she touched her cunt. In less than an hour, all the perverted desires had begun to invade her real life.
Sexy little bitch. Fuck-crazed cock-slut. Incestuous pervert.
“My… my mouth is a wet hole…” she swallowed and her breath came out in a hot rush as she whispered the last words, “for my brother to fuck.”
“Good girl,” Mark said and Sasha pressed her legs together.
Her fingers tightened on his waistband. They curled inside. Her fingertip touched his cock and she bit her lip to stop herself from moaning out loud.
I touched his cock. I touched my brother’s cock!
Mark took her hand away, then pressed it against the front of his shorts. Sasha’s fingers traced the bulge of his cock, but after only a few seconds he took that away, too. His grip on her hair released. He pulled down the shorts and Sasha was confronted with her brother’s real cock for the first time.
“Oh,” she gasped and reached for it.
Just as she wrapped her hands around it, a knock sounded at the door. the two of them jumped.
“Sasha?” their mother called. “Have you seen Mark?”
Sasha looked up, wild-eyed. Her eyes flew to the monitor, where the video of Mallory sucking her brother’s cock played soundlessly on the screen. Her brother’s naked cock stood erect, inches from her face.
“In here, Mom!” Mark called and grinned.
“Mark!” Sasha hissed.
Mark reached over to the keyboard, hit a hotkey combination, and the browser minimized. The door opened.
“Oh, hey. I was just coming to ask if you were okay,” their mother said as she poked her head around the door.
“I’m good,” he said. “Just a stupid girl thing. It’s worked out.”
“Okay,” Mother said. “Sasha, are you okay? Why are you all sweaty?”
Sasha stared at her brother’s cock, hard and hot. He hadn’t put it away. If their mother stepped into the room…
“Period!” Sasha squeaked and Mark laughed.
“Jesus, Sasha. Honesty isn’t always the best policy. Think of your brother.”
“I know about periods, Mother,” Mark said and rolled his eyes at her.
“Alright. Your dad and I are making sundaes. Come down and spend a little time with us.”
“Be right there, Mom,” Mark said.
Their mother shut the door.
“What the fuck!” Sasha hissed. “Your dick is out! She could have—“
Mark pushed his dick into her mouth. Sasha froze, unable to process the reality of what just happened. Mark’s cock was in her mouth. Her brother’s fat, rigid cock was in her fucking mouth!
“What is your mouth for, Sasha?” Mark asked.
Something in her head clicked and Sasha had her first hands-free orgasm in the chair, as Mark pushed more of his cock into her mouth.
“Goddamn,” he whispered. “Okay. You win biggest pervert for today.”
He pulled his cock out, tucked it away, and patted his stunned sister on the cheek.
“Come on,” he said. “Sundae’s are waiting.”
Sasha’s head spun with the trailing orgasmic bliss as Mark pulled her up from the chair and dragged her toward the door. Just like that, she was on her way down to confront her parents, after having her brother’s dick in her mouth.
Her heart hammered, threatening to burst out of her chest. Mark pulled her along, chuckling at her obvious discomfort, which somehow only made her hotter. He was taking control, pushing her, just like she’d wanted. And, fuck, was it hot!
