A sharp tension cut through the air like a knife. For a moment, Maddy was at an utter loss for words. It wasn’t just the pain and betrayal in Elliot’s eyes that bothered her, it was the slight but undeniable flicker of disgust, a sharp contrast to the glowing ways in which he’d looked at and spoken about her only minutes before. It was a look that made Maddy sick to her stomach.

Overcome with emotion, Maddy did the very first thing that came to her mind, almost on instinct. She dropped her towel, letting the morning sunshine bathe her naked body in golden light. There she stood, an ethereal, petite goddess, her nipples hard as they were exposed to the cool air.

“Look at me, El,” Maddy said, her voice quivering. “Look at me. Do you seriously think I could ever compete with Holly Anderson?”

“W-what?” Despite Elliot’s confusion and anger, Maddy noticed he couldn’t help but let his gaze be drawn to her tits. “What are you saying, Maddy?”

“I’m saying,” Maddy said, the words catching in her throat. Why is this so hard to confront? “I’m saying I never would’ve had a fucking chance with you if I didn’t… if I didn’t do the things I did.”

“Oh, come off it!” Elliot stood suddenly, blanket falling away to reveal his nakedness. Holly’s phone clattered to the floor with a thud. “You didn’t need to do that.”

Maddy flinched at the bitterness in his tone. Memories resurfaced of her brother slamming a door in her face, or brushing her off when she begged to spend time with him. This was more how she remembered her relationship with her brother over the last so many years. This was what she was used to.

“Don’t try to deny it, El. I saw the way you looked at her.” Maddy took a step towards her brother. “You told her she was a really cool girl. Remember?!”

“Oh, fuck all the way off, Maddy!” Elliot took a step towards Maddy, his face growing red with rage. “You don’t get to mess with my head, fucking catfish me, just because you’re insecure!” 

“Yeah, I did mess with your head,” said Maddy, growing indignant. “And I’d do it all again! Look where we ended up! Aren’t you happy?!”

Elliot clenched his jaw, silent for a moment, his eyes blazing with more fury than ever. “That’s not the point.”

“No, it is,” said Maddy firmly. “You’re welcome, little bro. Because without me you’d be fucking some OnlyFans whore.”

Maddy let her eyes drift, smiling slightly as her brother’s cock twitched. Mmmph, he’s so hot when he’s angry.

“How do you not see how fucking crazy that is?!” Elliot shouted, the vein on his neck bulging. “Why can’t you even say sorry? Even now?”

Maddy narrowed her eyes, suddenly finding herself unwilling to back down. “I don’t regret anything.”

“Well, I do.” Elliot forced his eyes away from Maddy, staring at the wall. “This whole thing was a mistake.”

“You don’t mean that,” Maddy said, a jolt of panic shooting through her. “You said you loved me!”

“That was before I knew just how fucking crazy you really are.” Elliot nearly growled, his erection half sprung with… pure rage? Maddy swallowed, her brother’s words feeling like a slap in the face.

“Bullshit,” she said, getting angry now too. And wet. She blamed it on the intense emotions of the moment, but she wondered if there was something else, something about the way her brother was looking at her. “You’re just embarrassed. An embarrassed little boy, trying to save face.”

“You want to know what the truth is?” Maddy continued, her chest heaving with what felt like years of pent-up resentment. “You’re a fucking coward, Elliot! You needed your big sister to manipulate you into actually facing your feelings. Because you’re too FUCKING pathetic to ever do it yourself!”

Elliot snapped. Maddy gasped as he rushed forward suddenly, slamming his hand against the wall behind Maddy. 

“This is FUCKED up, Maddy!” Elliot was seething, his eyes flaring with rage. “You lied to me! For weeks! How can I EVER trust you again?! Huh?”

Maddy quivered under her brother’s fiery gaze, her core melting with desire. Then, a hardness pressing against her thigh. Oh bro. You really are so easy to manipulate.

She smirked, reaching down to wrap her slender fingers around Elliot’s rapidly growing cock. He gasped, rage still plain on his face as he tried to fight his arousal. 

“Stop it,” he growled, but made no move to get away from his sister.

“I don’t buy it, bro,” Maddy said, biting her lip. “It’s obvious you’re turned on by the idea of your big sister controlling you. You get off to being lied to you. Deep down, you know that I know what’s best for you, that big sister did all this for you. This is what you need!”

“Unnngh,” Elliot grunted as Maddy worked her hand up and down his shaft, twisting around his slick cock head. “You! You’re a f-fucking brat, Maddy! You can’t just… unnngh, use your… fuck- your body to make all your problems go away! We have to… t-talk!”

“Oh, we need to talk now?” Maddy smiled, her anger dissipating as she watched her brother throw his head back, succumbing to the pleasure. “Fine. Let’s talk.”

Maddy suddenly spun around, bracing against the wall and arching her back so that Elliot’s cock slid against her dripping wet pussy. “Face the truth. Your cock belongs to me, little bro. You needed me to manipulate you.” 

The siblings moaned in unison as Elliot’s cock slipped, sliding up Maddy’s ass crack, pre-cum acting as lubricant. 

“Just let your big sister take care of you,” Maddy continued. “And thank me for saving you from wasting your time with that slut Holly.”

At this, Elliot growled, actually, really growled, sending chills down Maddy’s spine. He reached out, grabbing Maddy’s arms in a vice-like grip, pulling them to arch her back even more and hump his fully-erect shaft against her ass crack.

“I don’t think you’re in any position to be calling another girl a slut, Maddy.” His voice was low, dripping with arousal and fury. “You wanna call me a fucking coward? You can’t even get through one conversation without trying to get your holes filled.”

Maddy shuddered with delight as Elliot took control of the situation, leaning in to whisper in his sister’s ear. “I can’t forgive you for lying to me. Unless…” Elliot paused to bite his sister’s earlobe. “You’re willing to be punished.”

Gushing. Her pussy instantly grew ten times wetter at his words. In fact, Maddy felt like she might even orgasm from her brother’s voice alone. Her pussy ached to be filled, ached to be punished.

“Mmmm.” Maddy wiggled her ass, sliding her brother’s cock up and down between her flesh. “Why don’t you take out all your frustration on my tight, wet cunt, little bro?”

Elliot used a hand to guide his cock to the entrance of his sister’s pussy, sliding it along her labia to get it nice and wet. “Actually, I had a better idea.”

He suddenly shifted upwards, aiming his cock head right at the entrance of her pink, delicate rosebud.

“El! W-wait, I’m not…“

Elliot thrust forward, interrupting his sister as the first two inches of his shaft squeezed inside Maddy’s virgin ass, the wetness from her pussy allowing him the lubricant to slide forward.

“HOLY FUCK, EL!” Maddy cried out in pain and ecstasy, adjusting to the newfound sensation of her brother’s cock partially-buried in her ass. She’d experimented with butt plugs before, of course, but she’d never had an actual, live cock in her ass, certainly not anything as big as her brother’s monster cock. And he was barely inside her.

Elliot yanked his sister’s arms back further, using her body as further leverage to thrust himself a little deeper. “You’re a fucking asshole, sis. So I’m going to fuck your ass.”

Maddy moaned, barely listening as she enjoyed the sensations that were overwhelming her body. Even with just a few inches inside her, she felt stretched to the limit. But through that pain came a deeper, sweeter sensation of desire than any she’d ever felt before. It was a feeling that needed to be sated, something that had not yet been sated before. Maddy wanted more.

Nnnnggggh. Not quite what I had in mind. But maybe this is what El needs to get over this…

“Ohh god...” Elliot moaned, delirious with pleasure. “You’re squeezing my cock so fucking tight, Maddy. I-I’ve never felt- FUCKING anything like it.”

Elliot seemed stuck with only about four inches of his cock lodged inside his sister’s asshole. Even as Maddy tried to help by wiggling backwards, it almost seemed like she physically couldn’t take any more. But there was a deep ache inside her, throbbing, begging to be filled. She wasn’t going to be satisfied until Elliot pounded her ass.

“Ffffuck- bro,” Maddy moaned. “T-Take my ass… I want you… to p-punish me.”

Maddy’s high-pitched moans only drove Elliot into a renewed frenzy. He bucked his hips harder and harder, humping his sister’s ass as he desperately claimed another inch, then another, finally lodging three-quarters of his eight-inch cock firmly in his sister’s ass.

“Aieee! Oh! Fu-fuck! ohmygod, you’re so big! Fuck… You’re gonna- FUCK!” Maddy’s squeals punctuated each thrust, sweet pain and pleasure mixing together in roiling waves of indescribable arousal.

Elliot released his sister’s arms, letting her brace against the wall as he grabbed her ass cheeks instead for more leverage.

“You. Manipulative. Fucking. Bitch.” On the word bitch, Elliot thrust forward, finally spearing himself on Maddy completely, his balls slapping against her pussy as he hilted himself inside her.

Once inside, he wasted no time in sliding himself back out an inch before plunging back in, her asshole gripping onto his shaft so tightly Elliot wasn’t sure he could pull all the way out even if he wanted to.

“Do you know why I liked talking to Holly Anderson?” Every word punctuated another thrust, every thrust got a squeal of response from Maddy, and every squeal signaled another shooting sensation of pain and pleasure that made Maddy’s mind go dumb with fiery arousal. “It wasn’t because- fuck… because she’s prettier than you. You’re perfect, sis.”

Slap. Slap. Slap. Maddy’s hole was well lubricated now, allowing Elliot to rut her virgin ass with a mind-breaking rhythm.

“And you have… the perfect fucking ass,” Elliot groaned in ecstasy, using his sister’s behind like a sex toy.

“Ffffuck,” Maddy moaned as her pleasure grew, unable to even string together words as Elliot’s cock reamed her ass, hitting places she’d only ever dreamed of stimulating. “T-take it allllll out, b-bro. Nnnggh! T-take your-ffucking anger out on me!”

Her stuttered moans only seemed to make Elliot even hornier, his cock growing even harder inside of her, if that was even possible.

“I, unngh, talked to Holly to take my mind off you!” Elliot emphasized his words with smack, leaving Maddy’s ass cheek with a faint red mark. “You. And. You’re. Sexy. Fucking. Ass.”

He gripped her asscheeks hard enough to bruise, slamming into her ass over and over as he enjoyed the impossibly tight feeling of his sister’s asshole. Maddy could barely think, she was overwhelmed with sensations. But she didn’t care, she couldn’t, she only wanted Elliot to keep fucking her, to keep thrusting with all his anger, rage, and resentment.

With one final thrust, Elliot smacked his sister’s ass as he came, rage and arousal intertwining as he punished his sister’s ass, getting back at her for weeks of psychological manipulation. And when he came, he came harder than ever. 

Maddy tightened at the same time, the waves of excruciating pleasure finally reaching their peak. Every muscle in her body seized up, causing her already tight sphincter to grip Elliot’s cock even harder. He couldn’t pull out, it was impossible, not with her ass milking his cock - forcing him to cum.

“Iloveitloveitloveloveitlovelovelove-LOVEYOURFUCKINGCOCKINMYASS!” Maddy screamed as Elliot fucked her to an anal orgasm, her core shaking and quivering with a deep pleasure.

Elliot had the longest orgasm of his life. For a full minute, cum streamed out of his cock, painting his sister’s insides. When the pleasure finally faded, Elliot’s cock was still hard and lodged inside his sister’s ass. 

It took another minute of the siblings panting in silence, waiting for Elliot’s cock to soften enough to remove from Maddy’s asshole.

When he finally slid out, her sphincter gaped a little, a fresh load of cum dripping out of her no-longer virgin hole.

“Maddy,” Elliot finally breathed. “I said Holly was a cool girl because… because I thought she was letting me indulge my deepest fantasy. Being with you.”

Maddy turned around, her eyes fluttering as she recovered from the heights of pleasure.

“Do you still?” Maddy asked, afraid to meet her brother’s eyes. “Want to be with me?”

“Don’t fucking mess with me like that ever again.”

Maddy took a deep breath. “Okay. I won’t.”

 “I fucking mean it Maddy,” Elliot said.

“I got it.” Maddy smiled. Despite what she said, she wouldn’t mind if Elliot “punished” her like that again.

“So, we good bro?”

Elliot paused for a moment, then smiled, his eyes clear of anger. “Yeah, Maddy. We’re good.”

A comfortable silence descended on the siblings as they enjoyed the aftermath of their fucking, enjoyed the quiet ease between them.

But then the silence broke, a noise from downstairs.

“Maddy?! Elliot?! Is everyone okay up there?!” Footsteps. The sound of Eleanor marching up the stairs.

Maddy and Elliot looked at each other in sudden panic.

Shit, shit, shit. Did she fucking hear us?!

Elliot and Maddy were frozen with shock for a moment. They stood completely in the nude, cum and other bodily juices still coating their skin, their faces flushed with the aftermath of arousal.

“Hello?!” Eleanor’s shrill voice sounded in the hall, snapping the siblings out of their shock.

Spurred into frantic action, Maddy practically shoved her brother onto the bed, gathering her bundle of comforters around her into a nest. Elliot curled up behind her, obscured by the blankets, while Maddy wrapped the rest of them around her to cover her nakedness, or at least give herself the plausible deniability that she’d just been sleeping in her underwear.

“Maddy? Are you in there?” A knock at the door. She couldn’t delay anymore, Maddy knew. Their mom would have no qualms about barging in if she suspected anything was amiss with her kids.

“Come in!” Maddy called.

Eleanor entered the room a half-second later, her eyes sweeping the room intently. “Is Elliot up here? I thought I heard… screaming.”

Maddy yawned and stretched, pretending as if she was just waking up, even as her heart was beating out of control.

“Uhhh,” Maddy grunted. “He’s not in here, Mom.”

Eleanor crossed her arms, her eyes narrowing. “So, you weren’t talking to anyone up here?” 

She started pacing around the room, eyeing the corners as if suspecting to catch something incriminating hidden behind her desk or in a pile of laundry. God, if she comes too close…

“Where is he then?” Eleanor finally said, coming to a stop in front of Maddy, peering down at her with a piercing scrutiny.

“Elliot? Why would I know?” Maddy said as incredulously as she could. “It’s not my job to keep track of him!”

Eleanor clucked her tongue. “You should care about your brother. I know you two don’t get along so well, but… you set an example, Maddy. I’m counting on you.”

Maddy couldn’t resist rolling her eyes. Sure, Mom. Act like you care.

“If attitude is what you’re going to give me, then I’m sorry I even came up here,” Eleanor said, her voice laced with condescension. “I just wanted to celebrate the good news with you.”

Behind Maddy, Elliot shifted slightly. Maddy resisted the urge to punch him and kept her eyes fixed squarely on her mom, trying to hold her attention.

“Good news? What good news?”

“A letter arrived from Yale today. They’ve confirmed your acceptance and your new living quarters in the dorm. You’re set to move in next week.”

Maddy gasped, half in shock at the news, and half at the sensation of Elliot’s fingers sliding up her thigh. What are you doing, El?!

“I admit,” Eleanor continued. “I’m surprised after your… less than stellar performance at the end of the year. But I suppose they still want to give you a chance.”

Beneath the covers, Elliot’s hand shifted upwards, his fingers sliding between Maddy’s soaked pussy lips. She held back another gasp as he rubbed in slow circles up towards her clit. Though she’d just orgasmed from Elliot’s anal “punishment,” her pussy was still aching and ready to be touched. Even with her mom standing two feet away, it took everything in Maddy not to grab Elliot’s hand and shove it deep inside her dripping cunt.

“Hello? Earth to Madeline?” Eleanor raised an eyebrow at her daughter. “Are you going to say something?”

Maddy took a deep breath, trying to ignore the growing pleasure in her core as Elliot’s fingers massaged her clit. “I’m just, uh, really happy, Mom.”

“Hmph,” Eleanor said. “That you should be. But you’re going to have to step things up. You won’t be able to sleep in until nearly noon and flunk all your tests if you want to last more than a month there. Understood?”

“Understo-ahhh!” Maddy clapped a hand over her mouth in horror. The surprise of Elliot sliding his middle finger into her cunt had been too much to bear. *Damn it, Elliot! You’ve made your point!”

“Are you alright, Madeline?” Eleanor peered down at her daughter, puzzled.

“Fine… just tired,” Maddy said vaguely, trying to pass off her little moan as a yawn. But behind her indifferent facade, Maddy’s core tightened with desire, her body involuntarily clenching around her brother’s finger, eager for the pleasure of penetration.

“Right,” Eleanor said dismissively. “Well, you’re going to have to get to work. Start packing. I’ve already booked you a flight for Monday.”

Another finger slipped inside Maddy’s pussy, squeezed tight by her pussy walls. Elliot’s fingers curled upwards, scraping that bundle of nerves that made Maddy want to scream with pleasure. Holy fuck. I need to get Mom out of here now!

“Yes, I’ll start packing, Mom!” Maddy said with a little too much urgency. “Can you let...
