Four months after the first time she tasted himâreally tasted him, tongue pressed to the shallow slice on his chest while his pulse hammered against her lipsâshe would look back on that night and realize it had rewired something in her brain. The memory lived in her mouth. The copper-salt bloom of his blood. The way his breath had stuttered when her lips sealed over the wound. The guttural sound heâd made when she swallowed and kept swallowing, like she was trying to drink the ocean through a straw, and still wanted more.
But the thing that stuck with her mostâthe image she conjured on cold nights in roadside motels when Deanâs snores rumbled through the paper-thin wallsâwas the moment Samâs hand found the back of her head. Not gentle. Not tentative. His fingers twisted into her hair and held her there, and his voice came out wrecked: âLook at you. Just look at you.â
She could still feel the vibration of those words against her skull.
She could still taste the salt at the back of her throat.
That night changed things. It changed the way Sam looked at her across the breakfast table, eggs going cold on his fork. It changed the way he said her nameâsofter now, like the syllables had been sanded down. And it changed the geography of her body. Her mouth, which had always been a weapon, a hunger, a thing to hideâsuddenly became something Sam reached for in the dark.
But the story of how they got there didnât start with his chest wound.
It started two weeks earlier, with a lie sheâd told so many times it felt like truth.
---
âHunting accident.â
The cut on her forearm was fresh. Three inches. Clean. Dean squinted at it over the rim of his coffee mug and made a sound that was half-skeptical, half-impressed.
âWhatâd you do, fistfight a werewolf?â
âWendigo.â She tugged her sleeve down. âGot me with a branch.â
Sam, seated across the library table with a book open in front of him, didnât look up. But his eyes had stopped moving across the page.
That was the first thing sheâd noticed about Sam Winchester. He didnât need to stare at you to see you. He watched from the edges of his vision. He catalogued. He waited.
Sheâd been staying with them for six weeks by then. Long enough that Dean had stopped offering her the âyou donât have to hunt aloneâ speech and started handing her a beer without asking. Long enough that the bunkerâs corridors no longer felt like a labyrinth designed to swallow her. Long enough that Samâs silence had gone from polite to something heavier.
He was the one who found her digging through the hospitalâs biohazard disposal three towns over.
Sheâd thought she was being careful. Late shift change. South entrance. The night nurse took her smoke break at 2:15 a.m. like clockwork. Sheâd been inside for four minutes when the door swung open and there he was, silhouetted against the fluorescent hallway light, a gun in his hand.
Not pointed at her. Not yet.
âTell me youâre not what I think you are.â
His voice was steady. That was the terrifying part. Sam Winchester, all six-four of him, voice like a cello string pulled taut, and his eyesâGod, his eyesâwere doing that thing where they saw everything at once.
The blood pouch was still in her hand. Still cold. Still sealed. She was gripping it so hard the plastic strained.
âIâm not a vampire.â
âThen what are you?â
She could have lied. The lie was right there, pre-packaged, ready to go: Iâm a nurse. Iâm stealing supplies. Iâm a junkie. Iâm a medical student with a weird kink. But Sam Winchester was looking at her like he already knew the shape of the truth and was just waiting to see if sheâd have the decency to hand it to him herself.
So she told him.
âI eat people.â
The gun didnât move. Neither did his expression.
âNotââ she amended, ânot people people. I donât kill anyone. I donât hurt anyone. I justâŠâ She held up the blood pouch like it was a hall pass. âI need it. To survive. My body doesnât make something itâs supposed to make. Iron. Hemoglobin. I donât know the science. All I know is if I go more than a month without it, I start falling apart.â
Samâs jaw tightened.
âAnd your arms?â
She blinked.
âThe cuts. Dean mentioned them. You said they were hunting accidents.â
A pause stretched between them.
âSometimes,â she said, quieter now, âwhen I canât get to a hospital, I use my own. It buys me time.â
Sam lowered the gun.
Not fully. The barrel tilted toward the floor, but his finger stayed curled around the guard. He was still deciding whether she was a threat, and she could see the machinery of his mind turningâall those hunter instincts colliding with something else. Something that looked almost like pity.
She hated pity.
âYou can shoot me if you want,â she said. âBut Iâm telling you the truth. Iâm not a monster. Iâm just⊠not normal.â
The fluorescent lights hummed overhead. Somewhere in the distance, a door closed with a pneumatic hiss.
Then Sam did something she hadnât expected. He holstered the gun.
âThe hospital in Lebanon has better security,â he said. âIf youâre going to keep doing this, you should know which cameras are dummies and which ones arenât. I can show you.â
He turned and walked out.
She stood there for a long time, the blood pouch warming in her hand, and realized sheâd just been given something she hadnât earned.
Trust.
Or maybe curiosity.
With Sam Winchester, it was hard to tell the difference.
---
The nibbling started accidentally.
She didnât mean to bite him the first time. They were in the library, three days after the hospital confrontation, and heâd been explaining something about a sigil in a book he was reading. Sheâd leaned over his shoulder to look, and her mouth had been closer to his neck than sheâd realized, and before she could stop herself, her teeth had grazed the curve where his shoulder met his throat.
Not hard. Barely a touch. A whisper of pressure.
Sam went still.
âSorry,â she said, jerking back. âI didnâtâthat was an accident. I wasnât trying toââ
âItâs fine.â
His voice had gone strange. Lower. Rougher. He cleared his throat and turned back to his book, but the tips of his ears had gone pink.
She should have let it go. She should have backed away, retreated to her room, and pretended the whole thing hadnât happened. But her mouth was still tingling. Her teeth were still remembering the give of his skin, the warmth of him, the faint salt taste that lingered on her lips.
So she did it again.
The next day, she bit his forearm while he was reaching for a coffee mug. The day after that, she caught the meat of his thumb between her teeth while he was scrolling through his phone. Each time, he flinched. Each time, he didnât pull away.
By the end of the week, it had become a ritual.
Sheâd find him in the library, or the war room, or sprawled across his bed with a laptop balanced on his chest, and sheâd settle beside him like a cat claiming territory. Her mouth would wander. His wrist. His knuckles. The ridge of his collarbone. Sheâd press her teeth to his skin and just hold there, breathing him in, and something in Sam would loosen. His shoulders would drop. His breathing would slow.
âYouâre like a puppy,â he told her once, not looking up from his research. âA puppy with a chewing fixation.â
âIâm a cannibal.â
âSame thing.â
She bit down a little harder, and he sucked in a breath but didnât tell her to stop.
That was the thing about Sam. He never told her to stop.
---
The first time she tasted his blood, it was an accident.
Sheâd been nibbling on the inside of his wrist while he read a book one-handed, his other arm draped across the back of the couch where she sat curled against his side. Her teeth found the thin skin over his vein, and she bit down a little too enthusiastically. Not hard enough to do damage. Just hard enough to break the surface.
A bead of blood welled up. Copper-dark. Warm.
She froze.
Sam glanced over. âWhat?â
She couldnât answer. Her senses had narrowed to a pinprick. The world had collapsed to the single ruby droplet sitting on his skin, and her mouth was watering so hard her jaw ached.
âHey.â Samâs voice was careful now. He shifted, and his wrist moved, and the bead of blood smeared across his skin in a thin line. âTalk to me.â
âIt smells different.â
She barely recognized her own voice. It was throaty. Hungry.
âDifferent how?â
âNot human. Not entirely.â Her tongue darted out to wet her lips. âWhat are you?â
He didnât answer right away. She looked up at him, and his expression had gone shutteredâthe same look heâd worn in the hospital hallway. Assessing. Calculating risk.
âDemon blood,â he said finally. âWhen I was a baby. Azazel fed it to me. Itâs been in my system my whole life.â
A normal person would have recoiled. A normal person would have asked follow-up questionsâhorrified questions, sympathetic questions. But she wasnât a normal person, and the only thought that surfaced through the haze of her hunger was:Â Thatâs why.
Thatâs why his blood called to her like a siren song. Thatâs why, when sheâd bitten him casually over the past week, sheâd felt a pull she couldnât explain. His blood wasnât just blood. It was something rarer. Something stranger. Something that sang to the broken parts of her.
âCan Iââ She stopped. Swallowed. Tried again. âCan I taste it? Just a little. Just whatâs on your wrist.â
Samâs Adamâs apple bobbed.
âYouâre asking permission.â
âOf course Iâm asking permission.â She sounded almost offended. âIâm a cannibal, not an asshole.â
Something cracked in his expression. A laugh, maybe, or something softer. He lifted his wrist to her mouth.
âGo ahead.â
She didnât need to be told twice.
Her tongue met his skin before her brain caught up to her body, and the second the taste hit her, she understood what addiction actually meant. Not craving. Not dependence. Homecoming. That was the only word for it. His blood tasted like something her body had been missing since the day she was born. It was rich. It was metallic. It was laced with something dark and humming, something that made the fine hairs on her arms stand up and her vision sharpen at the edges.
She heard herself moan.
It was not a dignified sound. It was the sound of someone falling off a cliff and discovering they could fly. She sealed her lips around the tiny wound and sucked, gently, barely, and Samâs whole body went taut.
âOkay,â he breathed. âOkay, thatâsââ But he didnât pull his wrist away.
She let go. Not because she wanted to. Because if she didnât stop now, she wasnât sure sheâd be able to.
His wrist was clean. Sheâd licked every trace of blood from his skin, and the tiny wound had already started to close. Sam was staring at her with an expression she couldnât read.
âYour blood is incredible,â she said. Flat. Honest. âItâs like a drug. I could drain you dry and still want more.â
Samâs pupils had dilated. His breathing was uneven. But his voice came out steady.
âWe should probably set some boundaries.â
âProbably.â
âLike⊠not draining me dry.â
She nodded. âReasonable.â
âAnd not when Deanâs around.â
âObviously.â
âAndââ He hesitated. âYou have to tell me when you need it. No more sneaking around. No more hospitals. If you need blood, you come to me.â
Her heart was pounding so hard she could feel it in her teeth.
âSam. You donât have to offer that.â
âI know.â
âIâm not a vampire. Iâm not going to die if I donât get it. Itâs justâit helps. It makes the cravings go quiet.â
âI know,â he said again. And then, softer: âI know what itâs like to need something thatâs bad for you. Something you canât control.â He looked at her, and there was a whole history in his eyesâyears of demon blood addiction, of withdrawal, of clawing his way back to humanity. âIf I can make it easier for you, I want to.â
She didnât cry. She wasnât a crier.
But something in her chest cracked open, and she had to look away for a moment to compose herself.
âOkay,â she managed. âBoundaries. No draining. No Dean. I tell you when I need it.â
âAnd no more nibbling on my hand while Iâm trying to read.â
âThat oneâs non-negotiable.â
He laughed. It was the first time sheâd heard him laughâreally laughâand the sound of it settled somewhere deep in her stomach.
âFine,â he said. âYou can nibble. But if you draw blood, you have to warn me first.â
âDeal.â
She bit the pad of his thumb, just to seal the agreement, and Samâs laugh turned into a sharp inhale.
---
The arrangement worked better than it had any right to.
Every few days, when the cravings got too loud, sheâd find Sam wherever he was and press her face to the nearest available patch of skin. His bicep was her favorite spotâthe muscle dense and warm under her mouthâbut sheâd fed from his forearm, his shoulder, the tender skin inside his elbow. He always made the same sound when her teeth broke through: a low, bitten-off grunt, like he was trying not to let it show how much it affected him.
But it did affect him. She could tell.
She could tell by the way his pulse quickened under her tongue. The way his hands would find her hair or her shoulder or the back of her neck. The way heâd hold perfectly still, barely breathing, while she drank from him in slow, careful pulls.
âYouâre holding back,â he said one night, three days before the chest wound. She was curled against his side in his bed, her mouth working lazily at a fresh cut on his bicep. Dean was out. The bunker was silent. The only light came from the bedside lamp, casting warm shadows across Samâs face.
She pulled back. âHmm?â
âYouâre barely drinking. I can feel it.â
âIâm savoring.â
âYouâre rationing.â
She didnât deny it. He wasnât wrong. Every drop of his blood was precious to her, and she had this gnawing fear that if she took too much, heâd realize what sheâd known since that first taste: that his blood was the best thing sheâd ever had, and nothing else would ever compare.
âTake more,â Sam said.
His voice was quiet. But there was something underneath it. A command dressed up as permission.
Her mouth went dry.
âI donât want to hurt you.â
âYou wonât.â
âYou donât know that.â
âI trust you.â
Three words. Thatâs all it took. Three words, and the last of her restraint crumbled. She sealed her mouth over the wound and sucked harder, and Samâs head dropped back against the pillow with a groan that vibrated through his chest.
She drank.
His blood flooded her mouthâwarm, vital, electric. It tasted like copper and darkness and something that had no name. Something that made her feel powerful. Something that made her feel alive. She swallowed in long, greedy pulls, her tongue pressed to the wound to coax out more, and Samâs hand came up to cradle the back of her head.
âYeah,â he breathed. âThatâs it. Take what you need.â
She took.
When she finally pulled awayâonly because the wound had started to close and her jaw was aching from the effortâshe realized she was lightheaded. Not from blood loss. From pleasure. Her whole body was humming, and there was a warm, liquid sensation spreading through her limbs that had nothing to do with hunger and everything to do with the man whose arms she was currently lying in.
His eyes were dark. His lips were parted. His chest was rising and falling in shallow, rapid breaths.
âBetter?â he asked.
She nodded. She didnât trust herself to speak.
âGood.â His thumb stroked the curve of her skull. âNext time, donât wait so long. If you need it, come find me.â
She didnât tell him that she always needed it. That the need never went away. That his blood hadnât quieted her hunger so much as given it a target.
She just nodded again, and pressed her face to his shoulder, and tried not to think about how good he tasted.
---
The hunt that changed everything was a routine salt-and-burn in Oklahoma. A ghost. Nothing special. The kind of job theyâd done a hundred times before.
Except the ghost had put up a fight. It had manifested solid enough to swing a fireplace poker, and one of its wilder arcs had caught Sam across the chest before Dean put a salt round through its skull. The wound wasnât deep. A shallow gash that started just below his left collarbone and angled down toward his sternum. It bled enough to soak through his shirt but not enough to warrant stitches.
âYouâre gonna need a new flannel,â Dean said, surveying the damage as they packed up the Impala.
âIâm fine.â
âIâm just saying. Thatâs your favorite one.â
Sam peeled the ruined shirt off in the backseat and pressed a wad of fast-food napkins to the wound. Across from him, wedged into the corner with her knees pulled up to her chest, she stared at the blood seeping through his fingers and felt her mouth flood with saliva.
She didnât say anything. She couldnât. The craving had descended like a curtain, blotting out everything except the gleaming red line tracing down Samâs chest.
She spent the drive back to the bunker with her jaw clenched so tight her teeth ached. Sam kept glancing at her in the rearview mirrorâDean was driving, so Sam was riding shotgun, twisted around to check on herâand each time their eyes met, she had to look away.
He knew. She could tell he knew.
The question was what he was going to do about it.
Dean announced he was going to grab pie from the diner two towns overâthe one with the cherry lattice crust heâd been talking about for the past forty milesâand the second the bunker door closed behind him, she moved.
Sam was in his room, sitting on the edge of his bed, still shirtless, a fresh gauze pad taped over the wound. He looked up when she came through the door, and his expression shiftedânot surprise. Recognition.
âClose it,â he said.
She kicked the door shut behind her. The latch clicked.
âI needââ
âI know.â He leaned back on his hands. The motion stretched the skin over his ribs, made the gauze pull taut. âCome here.â
She crossed the room in four strides. Her knees hit the floor between his legsânot because she planned it, but because that was where her body wanted to be. Her hands found his thighs. Her eyes found his chest.
âCan Iâ?â
âYeah.â
She reached up and peeled the gauze away. The wound was ugly. Red. Raw. A three-inch slash that still glistened with fresh blood where the napkins hadnât quite done their job. It wasnât deep enough to be dangerous. It was deep enough to taste.
Her tongue met his skin before sheâd consciously decided to move, and Samâs entire body jerked like sheâd hit him with a live wire.
âFuck.â
The word came out strangled. His hands fisted in the bedsheets. She didnât stopâcouldnât stopâher mouth sealed over the wound and she sucked, and the taste of him hit her bloodstream like mainlined heroin. Copper. Salt. The dark humming thing that lived in his blood and sang to the hollow places inside her.
She moaned against his chest. The vibration made him shudder.
âYou have no idea,â he said, his voice scraping out of his throat, âwhat you look like right now.â
She lifted her eyes to his face without lifting her mouth from the wound. His pupils had swallowed his irises. His jaw was tight. A vein stood out in his neck.
She drew another mouthful of blood from him and swallowed.
âJesus.â His head dropped forward. His breath was hot against her hair. âKeepâkeep going.â
She kept going.
The wound wasnât producing much blood anymore, but she didnât need much. She traced the length of it with her tongue, cleaning every trace of red from his skin, and Samâs breathing got progressively rougher. His hands left the sheets and found her shoulders, her neck, the curve of her skull. He was trembling.
She pulled back to look at him. His lips were parted. His chest was heaving. And there was something in his expression she hadnât seen beforeâa hunger that matched her own.
âSam?â
He kissed her.
It wasnât gentle. It wasnât tentative. It was a kiss that had been building for weeks, ever since the first time her teeth grazed his neck in the library. His mouth crashed into hers, and she tasted her own hunger reflected back at her. His tongue pushed past her lips, and his hands twisted in her hair, and when he dragged her up into his lap, she went willingly.
The gauze pad had fallen to the floor. The wound on his chest was still glistening. She could feel the warmth of it through her shirt as she pressed against him.
âIâve been thinking about this,â Sam said against her mouth. âEvery time you bit me. Every time you fed. Iâve been thinking about what else your mouth could do.â
Her brain short-circuited.
âWhat else,â she repeated. Her voice didnât sound like her own. It was breathy. Eager. Hungry.
âYeah.â His thumb traced her lower lip. Pressed down. Parted her teeth. âYou like my blood so much. How about you try tasting something else?â
She didnât answer with words. Her hands dropped to his belt.
The sound of his zipper was obscenely loud in the quiet room. Samâs breath caught as her fingers worked the button of his jeans, his hips lifting automatically to help her tug the denim down over his thighs. He was already hard. She could see the outline of him straining against his boxer briefs, and the sight made her mouth water in a way that had nothing to do with blood.
âYouâre sure about this?â she asked. The last shred of her sanity. The final lifeboat before she drowned.
Samâs answer was to hook his thumbs in his waistband and shove his underwear down.
Sheâd known he was big. She wasnât an idiot. You couldnât share a bunker with someone for months and not accidentally catch glimpses of things. But seeing him like thisâflushed, straining, the head already slickâmade her brain go quiet in a way it never did.
âIâm sure,â he said. âAre you?â
Instead of answering, she leaned forward and ran her tongue from base to tip.
Sam made a sound sheâd never heard him make before. It wasnât a groan. It wasnât a grunt. It was a whimper, high and desperate, and his hips bucked involuntarily off the bed.
âSorry,â he gasped. âI didnât mean toâyou justââ
She did it again. Slower this time. Tracing the vein on the underside of his shaft with the point of her tongue. Tasting the salt of his skin. The faint musk. The warmth.
âGod.â His head fell back. His throat worked. âYouâre going to kill me.â
She smiled against him. âOnly a little.â
And then she took him into her mouth.
All of him. In one motion. The head of his cock hit the back of her throat, and she didnât stopâdidnât pause, didnât gag, didnât even feel the reflex that had always been there before. The blood was still singing in her veins, and it had rewritten something fundamental about her body. Her throat opened. Her jaw relaxed. She swallowed, and the head slipped past her soft palate, and Sam shouted.
âOh fuckâfuck, waitââ
His hands scrambled for purchase. One found the headboard. The other twisted in the sheets. She looked up at him through her lashes, her nose pressed flat against his abdomen, and watched his composure shatter.
âHow are youââ He couldnât finish the question. His hips twitched. The movement pushed him impossibly deeper, and she made a sound of contentment that vibrated around him.
âYouâre going to make me come,â he warned, his voice cracking. âIf you keep doing thatâif you donâtâIâm going toââ
She pulled back just far enough to free her mouth. A string of saliva connected her lower lip to the tip of him. She licked it away.
âThen come.â
She swallowed him again.
This time, she didnât stay still. She set a rhythmâslow at first, then faster, then impossibly deep. Her head bobbed in his lap, and Samâs hips rose to meet her, and the sounds he was making were the filthiest things sheâd ever heard. Broken moans. Half-formed words. Pleas that never quite made it past his teeth.
âYourâmouthâI canâtâitâs tooââ
His hand found the back of her head. Not pushing. Not guiding. Just holding, like she was the only solid thing in a world that had gone liquid. His fingers twisted in her hair. His thighs trembled under her palms.
She hollowed her cheeks and sucked.
Samâs back arched off the bed. His heel slammed against the mattress. A guttural sound tore out of his throatânot her name, not a word, just a noise of pure, obliterating pleasureâand then he was coming, hot and thick against her tongue, and she swallowed that too.
Everything he gave her. She took it.
She kept her mouth on him through the aftershocks, through the twitches and the gasps, through the way his hand went slack in her hair and his body sagged against the pillows. She kept her mouth on him until he was soft, and then she kept her mouth on him anyway, her tongue moving in lazy circles around the head, cleaning the last traces of salt from his skin.
By the time she realized what was happening, he was hard again.
âNo way,â she murmured, pulling back to look at him. His cock was flushed and glistening, rising from the dark thatch of hair like it had never left.
Samâs eyes were half-lidded. His chest was glazed with sweat. The wound on his chest had closed, but her saliva still glistened on his skin.
âYou did that,â he said hoarsely. âYou justâkept goingâand Iââ
âAre you complaining?â
âNo.â He swallowed. âJustâgive me a second. Iâm sensitive.â
âI donât want to wait.â
She took him in her mouth again, and this time the noise he made was almost pained. Overstimulation. She could feel it in the way his whole body flinched, in the way his thighs tensed, in the way his hand flew to her shoulder like he couldnât decide whether to push her away or pull her closer.
âItâsâfuckâitâs too muchâI canâtââ
She pulled off just long enough to look up at him. Her lips were swollen. Her chin was slick.
âYou can,â she said. âYou will.â
She didnât deep-throat him this time. She went slower, gentler, working him with her tongue and lips while he shuddered and gasped above her. Her hand cupped his balls. Her other hand braced against his hip. She took her time, drawing him back from the edge of overstimulation into the building warmth of a second climax.
When he came againâharder than the first time, his whole body curling forward around her headâhe said her name. Just once. Just a syllable. But the way it broke in his mouth made her feel like sheâd swallowed the sun.
She pulled off him gently. Pressed a kiss to the inside of his thigh. Rested her cheek against his leg and looked up at him.
Sam was wrecked. His hair was plastered to his forehead. His chest was heaving. His hands were shaking. But when he looked down at her, there was something in his eyes that made her heart stutter: softness. Pure, unguarded softness.
âCome here,â he rasped.
She crawled up his body. His arms wrapped around her. His lips pressed to her forehead, her temple, the corner of her mouth.
âYouâre incredible,â he murmured. âYou know that?â
She tucked her face into the crook of his neck and smiled against his skin.
âIâm a cannibal with a blood addiction.â
âSame thing.â
She bit his shoulder. Not hard. Just a reminder. His laugh rumbled through his chest, and she felt it in her teeth.
Outside, the bunker door groaned open. Deanâs voice echoed down the corridor.
âI got pie! Somebody better be alive in here!â
Samâs arms tightened around her. She felt him smile against her hair.
âDonât move,â he whispered. âWeâve got three minutes before he comes looking.â
âAnd then what?â
âAnd then we pretend we werenât just doing what we were just doing.â
She snorted. âHeâs going to know.â
âProbably.â
âGood.â
She pressed a kiss to the center of his chestâright over the woundâand felt his heartbeat flutter under her lips.
