Chapter 1: The Morning After: Best Friends on the Edge
Her brain, still sticky with sleep, fumbled for context. Movie night. Too much cheap wine. Passing out on Kevin’s stupidly comfortable king-size bed because her apartment’s AC was broken again. She’d worn an old Sleep Token t-shirt and cotton shorts to bed.
She glanced down. Her breasts were bare, pale and full in the muted light, nipples pebbled in the conditioned air. Shit. The t-shirt was gone, twisted somewhere near her knees. She must have wrestled it off in her sleep, a habit from her own sweltering apartment. A flush of embarrassment warmed her chest, but it was just Kevin. He’d seen her in every state of disarray for over a decade. He was probably still asleep on his side of the vast mattress, orderly and quiet.
She started to shuffle, intending to tug the shirt back up, when the line of heat at her back shifted.
A heavy arm slid across her waist, pulling her firmly against a body that was very much not wearing pajamas. Every muscle in her body locked. Her ass pressed against a firm, hot length that could only be one thing. It was thick, already half-hard, and nestled in the cleft of her rear. Kevin’s breath, slow and even, stirred the hair at her crown.
Oh, god. Oh, fuck. He’s naked. He sleeps naked. I knew that. Why did I forget he sleeps naked?
Her heart hammered against her ribs, a frantic bird. She should move. She should extricate herself. But a treacherous, curious part of her mind, the part always hidden beneath her self-deprecating jokes, focused on the feel of him. The solidity of his chest against her back. The way his cock, even in its semi-hard state, felt monumental. A strange, liquid heat pooled low in her belly, completely at odds with her panic.
Kevin stirred behind her. His arm tightened, his hand splaying possessively across her bare stomach. A soft, sleep-rough groan vibrated against her spine. He was waking up. And he was waking up with her.
His thoughts came in a sluggish, warm haze. The familiar scent of her shampoo—something coconuty and cheap—filled his senses. Soft curves fitted perfectly against him. Ashlee. A dream, maybe. A good one. He nuzzled into her hair, his body reacting instinctively to the press of her bare skin. He was hard now, fully, the blood rushing south with a predictable, morning urgency. His hips gave a slight, involuntary roll, sliding his length against the soft cotton covering her ass. So good. So warm.
Then his consciousness caught up, sharp and cold.
Her shirt’s off.
His eyes snapped open. The city lights. His bedroom.
His bedroom. Ashlee. In his bed. Half-naked. His cock was pressed against her, achingly hard, a traitorous demand against the small of her back. Every instinct honed by years of brotherly protectiveness screamed at him to recoil. To laugh it off. To make a stupid joke and defuse the nuclear tension now crackling in the air between their skin.
But he didn't move. He couldn't. Her skin was so soft. The scent of her, sleep-warm and familiar, was doing something catastrophic to his higher reasoning. He felt her heart thrumming against his forearm.
“Kev?” Her voice was a tiny, shattered thing in the vast quiet of the room.
“Your shirt,” he managed, the words gravel in his throat. “It’s… you’re…”
“I know.” She swallowed audibly. “I get hot. I’m sorry. I should go.” But she didn’t move either. Her body was rigid, then melted slightly backward, a minute press into him. A question.
That tiny movement broke him. The last fragile thread of restraint snapped.
His hand on her stomach slid upward, palm rough against the smooth plane of her skin, until his fingers brushed the underside of her breast. She gasped, a sharp intake that hitched into a moan as his thumb swept over her nipple. It was already a hard peak against his calloused skin. Perfect.
Perfect. The sound of her moan, that broken little sigh, was a match thrown into a room soaked in gasoline. Kevin’s hand froze on her breast. His brain screamed one last, coherent warning.
This is Ashlee. Your best friend. The girl who cried when she scraped her knee at your tenth birthday party. The one you buy weird soda flavors for. Stop.
But his body, all of it, throbbed in unanimous, aching rebellion. Her nipple was a tight bud against his palm. Her ass pressed back against his erection, a silent, answering plea. The heat between them was a living thing, smothering the voice of reason.
Ashlee’s mind was a white-noise hum of panic and want. He’s touching me. Kevin is touching my tit. And he’s so hard. Oh my god, he’s huge. Every insecurity she’d ever confessed to him in the dark came rushing back. Her average face. The gap in her teeth. Her soft stomach. But his touch wasn’t disgusted. It was hungry. It made her feel powerful in a way nothing ever had.
“Kev,” she breathed again, not a question this time. A statement.
He moved. In one fluid, powerful motion, he rolled her onto her back. The white sheets were cool against her bare skin. He loomed over her, braced on his hands, his face shadowed in the dawn light. His blue eyes were almost black, pupils blown wide with a conflict she could physically feel. His cock, thick and ruddy and veined, curved up towards his stomach, an obscene exclamation point to the tension in the room.
“We can’t,” he said, the words strained. “Ash, fuck, look at you. We can’t.”
“Why?” she whispered, her eyes darting from his face to his cock and back. She reached a hand up, trembling, and let her fingertips brush his chest. The muscle there jumped under her touch. “Because we’re friends?”
“Yes!” He laughed, a harsh, disbelieving sound. “That’s the whole fucking reason! You’re my best friend. I don’t… I can’t screw this up.” But he didn’t move away. He stayed there, caging her in, letting her touch him.
“It doesn’t have to screw anything up,” she said, her voice gaining a sliver of her usual quirky bravery. She let her hand trail lower, over the defined ridges of his abdomen. He sucked in a sharp breath. “It’s just a thing. A weird, horny, morning thing.”
His resolve was a dam with visible cracks. He watched her small hand with a kind of horrified fascination as it descended. “Ashlee, no.”
Her fingers touched the hot, silken skin at the base of his shaft. He jerked as if electrocuted.
Just the tip, she thought, her own pulse hammering in her ears. Just to see. She wrapped her hand around him. He was so thick her fingers didn’t meet. The skin was like hot velvet over steel. A drop of moisture beaded at the tip. The sheer, visceral reality of him, of Kevin, in her hand, short-circuited something in her. A giggle, born of pure nervous delirium, bubbled out of her.
“It’s so… solemn,” she whispered, her eyes wide.
A startled laugh burst from him. “It’s a dick, not a judge.”
“It’s judging me right now. It’s all, ‘I am the mighty cucumber of justice.’”
He groaned, dropping his forehead to hers, his body shaking with a mix of lust and laughter. “You’re impossible.”
The playful break was all she needed. Her other hand came up and dug into his ribs.
“Hey!” He flinched, a true, involuntary spasm.
“Tickle fight!” she shrieked, scrambling beneath him, both hands attacking his sides with a ferocity born of a thousand past couch-skirmishes.
“Oh, you’re dead!” he growled, the dynamic shifting instantly, beautifully, into familiar territory. He captured her wrists in one large hand, pinning them above her head on the pillow. He was so much stronger. He leveraged his body, knees coming up to straddle her hips, then her ribs, shifting up until he was sitting squarely on her chest, her head trapped between his powerful thighs.
She was laughing, truly laughing, breathless and squirming. “Unfair! You have a gravity advantage!”
He looked down at her. Her vibrant red hair was fanned out around her head, her face flushed, that little gap between her teeth visible as she gasped for air. And his cock, fully erect now, jutted out just inches from her mouth. The juxtaposition was brutally erotic. The laughter died in his throat.
Her laughter faded too, her eyes locking onto the thick head of his cock, so close she could see every detail, smell the clean, musky scent of him. Her breath hitched.
“Say uncle,” Kevin said, his voice rough. He gave his hips a slight shift, letting the heavy weight of his balls brush her chin. Then, with a deliberate, slow control, he lifted his cock and brought it down, slapping the shaft against her cheek. It wasn’t hard. It was a taunt. A hot, velvery smack that made her whole body clench. Thwack.
I have his dick on my face. The thought was surreal, filthy, exhilarating. Kevin’s dick is slapping my face.
“Uncle,” she breathed, but it was a lie. Her tongue darted out, a quick, pink flash, and licked the sensitive spot just under the head where his pre-cum had smeared.
Kevin saw it. He felt it. A bolt of pure lightning shot up his spine. “Fuck, Ash,” he moaned, his hips bucking forward instinctively. The head bumped against her lips. “Don’t. Don’t do that.”
“Why not?” she murmured, turning her head, chasing him with her mouth. Her lips brushed his shaft. “You won. Winner gets a prize.”
This is wrong. This is my best friend’s mouth. The thought was a mantra, but it had lost all meaning. It was just words. The reality was the wet heat of her breath, the teasing pressure of her lips. The taboo of it was an electrocution, every nerve ending screaming alive. His reluctance wasn’t gone; it was being incinerated cell by cell.
“It changes everything,” he tried, but his voice was weak.
“It changes nothing,” she echoed his earlier sentiment, her eyes serious now, looking up the length of his body at him. “You’re Kevin. I’m Ashlee. This is just… a new thing we’re doing.” And then she opened her mouth, took the broad head inside, and sucked.
Oh, Christ.
The feeling was catastrophic. Wet, hot, perfect pressure. Her tongue swirled. A low, guttural groan tore from his chest. His hands, which had been braced on the headboard, now came down to cradle her head, his fingers tangling in her red hair. Not forcing. Just holding. Anchoring himself to the world as it dissolved.
I have him in my mouth. The weight and salt of him was overwhelming. She relaxed her jaw, letting him push a little deeper, her mind blissfully blank of anything but sensation. The way he trembled. The little choked sounds he made. This was Kevin. She was making him feel this.
“You’re my best friend,” he gasped, looking down at the surreal sight. “I can’t believe I’m inside my best friend’s mouth.” The sentence, spoken aloud, was the most perversely arousing thing he’d ever heard. “My best friend’s throat.” He guided her head, a gentle pressure, and she took more, her eyes watering as he breached deeper. The trust in it, the absolute surrender, undid him completely.
He set a slow, deep rhythm. She met him, her hand coming up to wrap around the base of him, working what she couldn’t take. There was a whimsical, filthy joy in it. He’d gasp, “You’re a fucking natural,” and she’d hum in response, the vibration making his knees weak. He’d whisper, “Your mouth is a goddamn miracle,” and she’d pull off with a soft pop and grin up at him, that gap-toothed, wicked grin, and say, “Told you I was good at something,” before diving back down.
The playfulness gradually burned away, consumed by a gathering, urgent heat. His strokes became more possessive, less controlled. He was hitting the back of her throat now, bumping against it with each deep push. Tears tracked from the corners of her eyes, but she didn’t pull away. She gripped his thighs, urging him on.
She gripped his thighs, urging him on.
With a wet, sucking sound, he pulled his cock from her mouth. It glistened under the bedside lamp. He held it loosely, then gently tapped the heavy, slick head against her cheekbone, once, twice, a possessive little pat-pat. Then he shifted his grip, his palm open, and gave her a soft, firm love slap on the same cheek with his cock. It wasn’t a strike of anger, but of claiming. A thwack of damp skin on skin that made her eyes flutter.
“I want you to deepthroat me, sis,” he said, his voice low and raspy with need. He was using their old, sibling-like banter, twisting it into something dark and new. “Do you think you can take all nine inches? With my help?”
Ashlee looked up at him, her lips swollen, her cheek flushed from where he’d tapped and slapped himself against her. A flicker of her old whimsy broke through the overwhelming lust. She grinned, that familiar gap-toothed smile now a beacon of sinful promise. “I can try,” she chirped, her voice hoarse.
“That’s my girl,” he murmured.
He guided himself back to her lips. She opened wide, taking the head, relaxing her jaw as he pushed forward. The first few inches were familiar now. Then he met resistance. He cradled the back of her head, his fingers firm in her hair. “Relax your throat,” he coached, his own breath coming in short pants. “Just let it happen.”
He pushed steadily. She gagged, a harsh, involuntary convulsion that sent tears springing to her eyes. Her body jerked.
“Shhh, just breathe through your nose,” he soothed, but he didn’t retreat. He applied relentless, gentle pressure. Her throat opened around him, a tight, hot, impossibly wet sleeve. He watched, mesmerized, as inch after obscene inch disappeared between her lips until his pubic bone pressed against her nose and he was fully sheathed, fully impaled in her throat. Her body was rigid, her eyes streaming, a low gurgle coming from her.
The feeling was astronomical. A total, constricting heat that threatened to end him instantly. He held himself there, buried to the hilt, feeling the frantic flutters of her gag reflex around the base of his shaft.
A playful, dark impulse took him. He leaned forward slightly, his free hand coming up. With his thumb and forefinger, he gently pinched her nostrils shut, plugging her nose.
Her eyes, wide and watery, flew open in startled panic. She was completely filled, front and back. No air. Impaled and captive. A wild, muffled sound vibrated through her throat and directly up his cock. He held her there for three eternal seconds, watching the blend of terror and euphoria in her expression, feeling her body begin to struggle beneath him. Then he released her nose and slid back, pulling almost all the way out with a slick, obscene pop.
Air rushed into her lungs in a ragged, wet sob. She choked, coughing, drool and tears mixing on her chin. “Fuck,” she gasped, the word broken. “Oh, fuck, Kevin.”
“You did it,” he breathed, awe and brutal arousal sharp in his tone. He was hovering over her now, his cock dripping onto her chest. “You took all of me. Every last fucking inch.”
Every last fucking inch.”
The words hung in the air between them, a testament to what she’d just done. Ashlee gasped, her throat raw, her body humming with a wild, conquered feeling. Kevin looked down at her, his blue eyes wide with a kind of reverent shock.
“Again,” he breathed, his voice shredded. “Hands behind your back. Use just your mouth. Just that spectacular throat.”
The command, and the unexpected compliment wrapped around the word ‘spectacular’, sent a new jolt through her. She obediently laced her fingers behind the small of her back, arching her chest toward him, making herself an offering. The position made her feel vulnerable, exposed, and utterly powerful.
He guided himself back to her lips. This time, she knew what to do. She opened, taking him in, relaxing her jaw as he pushed forward, past her lips, over her tongue, into the tight channel of her throat. It was easier this time, her body adapting to the violation. He set a rhythm, deep and punishing, using his grip on her hair to piston himself in and out.
“Fuck, Ashlee,” he groaned, watching his slick length disappear into her face. “I can’t believe I’m in my best friend’s throat. I can’t believe my little sister is sucking my cock like a goddamn porn star.”
The words were a chaotic mix of taboo and praise. Little sister. Best friend. Porn star. They shouldn’t work together. They ignited her. She moaned around him, the vibration pulling a ragged curse from his lips.
He fucked her mouth with a focused intensity, his hips driving forward. “You have no idea,” he panted, “what you look like. An average face, completely blissed out, taking this. Your average, soft body just yielding. But this mouth… Christ, this throat… it’s a fucking masterpiece. It’s like you were built for this. Just for taking my cock.”
The backhanded compliment—average face, average body—should have stung. It did, for a microscopic second, a ghost of her old insecurity. But it was vaporized by the heat of his praise for her mouth, by the raw, physical truth of him using her, claiming her in the most base way possible. She was built for this. For him. Right now.
His rhythm became erratic, brutal. He was chasing it. “This changes nothing, Ash,” he grunted, slamming deep, holding himself there as she gagged softly around the intrusion. “I’m gonna feed you the largest load of cum you’ve ever swallowed. I’m gonna shoot it straight down your throat and plug your nose so you take every drop. And tomorrow… tomorrow we get coffee. We’ll always be friends. I’ll always be your big brother.”
The contradiction was insane. It was the hottest thing she’d ever heard.
He pulled out until just the tip rested on her tongue. His body was trembling, a coiled spring. “Open wide. Show me. Show me where you want it.”
She opened her mouth, sticking out her tongue, her eyes locked on his. She looked ruined, and she knew it. Tears, drool, flushed skin.
With a guttural roar that was nothing like his usual confident tone, he shoved back in, hilting himself one final time. His body locked. A hot, pulsing flood erupted from him, jetting directly into her throat. She swallowed convulsively, the salty, bitter taste filling her senses as he kept pumping, release after release. True to his word, his hand came up and pinched her nostrils shut again, sealing her in the moment. She was a vessel, receiving him completely, her throat working to swallow every spurt as he trembled above her, whispering “yes, yes, take it all, good girl,” until he was spent.
He slowly slipped out of her mouth, soft and slick. He released her nose. She dragged in a ragged, wet breath, cum and saliva on her chin. He collapsed beside her on the vast bed, both of them staring at the ceiling, the only sound their staggered breathing and the distant hum of the waking city below.
He collapsed beside her on the vast bed, both of them staring at the ceiling, the only sound their staggered breathing and the distant hum of the waking city below.
The silence wasn’t quiet. It was full of the things they’d just done.
Kevin’s mind replayed the last ninety seconds on a brutal, exquisite loop.
I can still stop. It’s not too late. The thought had been a flashing beacon as he felt the pressure coil, unbearable, at the base of his spine. Her throat had been a wet, gripping heaven. Her eyes, wide and trusting and a little scared, looked up at him from a face he’d seen a thousand times. A face he’d teased about toothpaste smudges and bad haircuts. I don’t think I’m ready to come in her mouth yet. I can’t do that to my little sister. The title, a joke of over a decade, had never felt so loaded, so dangerously wrong. It was the wrong thought. It was the only thought. Little sister. And then her tongue had swirled, and the beacon shattered into a million dark, glittering pieces. Fuck it.
Beside him, Ashlee’s thoughts were a frantic, joyous hum. Oh my god I don’t think I’m ready for him to come in my mouth what is happening this could change everything this could ruin our friendship. The taste of him, salt and skin and something uniquely Kevin, was still on her tongue. She’d panicked for a second, the reality of it hitting her. I can’t believe I’m sucking my big brother’s 9 inch cock. The sheer, ridiculous impossibility of it. Then the warmth had flooded her throat, and the panic melted into a primal, smug satisfaction. God, the taboo is so hot.
A drop of cum, escaped from her swollen lips, traced a cool path down her temple into her hairline.
“Ew,” she said, her voice a wrecked, hoarse thing. She didn’t move to wipe it. “I think you got some in my ear. That’s a new one.”
The sheer, absurd normality of her tone broke the tension. Kevin let out a breath that was half-laugh, half-sob. He turned his head on the pillow to look at her. She was a mess. Red hair stuck to her damp forehead and cheeks. Her lips were puffy. Her cheek had a faint red mark from where he’d… well.
“Sorry,” he said, not sounding sorry at all. He reached over with a thumb, wiping the streak from her temple. His fingers lingered, brushing her skin. “Ear canal’s probably not the intended destination.”
“I think the intended destination was my spleen,” she croaked, swallowing again. “I felt that in my toes. And I’m pretty sure I saw a brief vision of my third grade teacher, Mrs. Lowell. She was judging me.”
He laughed, a real one this time, the sound rich and familiar in the opulent room. “What did Mrs. Lowell say?”
“She said my cursive was sloppy and so was my throat-fucking technique.” Ashlee grinned, that gap-toothed, ridiculous grin, and it was the most beautiful thing he’d ever seen.
“Your technique was fucking stellar,” he said, the crudeness feeling necessary, a anchor in the surreal sea. “A-plus. Gold star. Would absolutely ruin a friendship with again.”
The word ‘ruin’ hung there for a second. Her grin softened. She turned her head to meet his gaze. Their noses were inches apart on the shared pillow.
