Summary:

“That’s so pathetic,” Megumi teases, and Yuji whines, pulling Megumi close and pressing his face against his lower stomach. Megumi brings his hand up and strokes Yuji’s hair. “I thought you fed just recently. Are you really that hungry?”

“For you,” Yuji says, muffled by Megumi’s skin. “Always hungry for you.”

Megumi accidentally triggers Yuji’s bloodlust.

Work Text:

Megumi immediately senses something is wrong the moment he wakes up. An uncomfortable wetness slicks the insides of his thighs, and when he gets up from bed, he looks down and sees that the sheets are stained with a crimson hue.

“Shit,” he mutters. “Shit, shit.”

He pulls his pants down and looks at the mess he’s made of his underwear, an involuntary groan releasing through his lips when he realizes that he has to deal with this now—despite having just woken up, and not wanting to even keep his eyes open.

Yuji rolls over slightly in bed, murmuring something in his sleep. In a panic, Megumi immediately pushes him away from the blood.

“Careful, Yuji,” he says. “I started my period. I’ll have to change the sheets.”

Blinking, and looking up at Megumi through bleary eyes, Yuji mumbles, “Your period…?”

“Yeah. Actually, can you get up for a second? I’m sorry, I just need to put these sheets in the washer. And my clothes—they’re fucking ruined.”

He feels bad, knowing that Yuji probably just managed to fall asleep, with his nighttime routine being the complete opposite of Megumi’s. He can see the sun peeking in through the curtains, and he quickly pulls them shut before they’re able to do any damage to Yuji.

Yuji stands up and yawns, rubbing at his eyes as he frowns sleepily. “Mm. Ruined how?”

“They’re stained with my blood, Yuji,” Megumi says, a hint of irritation in his tone. He can’t help it. He knows it’s not Yuji’s fault, but he just wants to get this shit over with so he can shower and go back to sleep.

At the mention of the vital substance, Yuji seems to perk up. “Blood?” he says.

Megumi rolls his eyes. “Christ, you’re like a dog. Yes, Yuji, blood. You know, my period? The menstrual cycle? The thing that happens to me every damn month?”

“Hey, don’t get snippy with me,” Yuji says, a pout forming on his face. “I just woke up.”

Megumi sighs. “I’m sorry. I’m just frustrated. This rarely ever happens, and when it does, it really pisses me off.”

Yuji walks up to Megumi and wraps his arms around his shoulders, holding him close to his body. He presses a small kiss to his temple.

“I know, my love,” he says. “Don’t worry about all of this, okay? Just go take a bath. I’ll deal with your clothes and the sheets.”

Megumi hesitates, but eventually, he slowly nods. “Okay,” he mumbles, although he’s still reluctant to let Yuji clean up after him. “…Thank you.”

He leaves his soiled clothing in the laundry hamper before he goes to the bathroom and turns on the shower faucet. He won’t take a bath—he really does not want to be awake for that long. A quick shower will do, just to get rid of the mess he’s made between his legs, and then he can crawl back into bed, under their spare blanket, and go back to sleep.

When Megumi returns to the room with a towel wrapped around his waist, he walks in on Yuji laying in the bed with his hand shoved down his pants, moaning softly into a piece of cloth that covers his face.

“The fuck–” Megumi cuts himself off as he flicks up the light switch, and watches as Yuji slowly pulls the fabric off of his face.

“Oh. Hey,” he says, completely shameless while being caught in the act. “That was quick. I thought you were taking a bath?”

“Is that my underwear?” Megumi says, ignoring Yuji’s questioning.

Now, Yuji has the audacity to blush. He takes his hand out from his pants and gives a small laugh, looking up at Megumi through half-lidded eyes.

“Mm, yeah…” He shrugs a little. “Sorry. The smell… it made me hungry.”

Megumi squints his eyes and walks closer toward the bed. “Your fangs are out.” He looks around the room. “Did you even clean up like you said you would?”

“Uh… I put the bedsheets in the laundry basket.”

An exasperated sigh leaves Megumi. “You were supposed to put them in the washing machine. The blood’s going to stain now, Yuji.”

“Who cares?” he says. “Come here. God, you look so good.”

Megumi rolls his eyes, but there’s a small smile threatening to pull at the corners of his lips. “I have to get dressed.”

“No!” Yuji nearly shouts, sitting up on the bed and pulling at Megumi’s towel. He looks up at him with wide, pleading eyes, pupils blown out with pure want. “Don’t get dressed. Please.”

Megumi notices the thin layer of blood on Yuji’s chin. He takes hold of his jaw and swipes his thumb over the red smear. Yuji opens his mouth and lets Megumi press his finger in, running it along his fangs, feeling them graze his skin. He watches as Yuji licks the blood off his fingertip, shivering with the promise of even more blood that remains hidden inside of Megumi’s veins.

“Have you been sucking the blood from my underwear?” Megumi says as he caresses Yuji’s chin, a small smirk playing on his face.

Yuji nods. “Mhm,” he mumbles as best as he can with Megumi’s finger in his mouth. “You taste s’good, Megumi…”

He presses his palms on either side of Megumi’s waist and slips his fingers beneath the towel, trying to unwrap it and reveal Megumi’s naked body.

“That’s so pathetic,” Megumi teases, and Yuji whines, pulling Megumi close and pressing his face against his lower stomach. Megumi brings his hand up and strokes Yuji’s hair. “I thought you fed just recently. Are you really that hungry?”

“For you,” Yuji says, muffled by Megumi’s skin. “Always hungry for you.”

He presses a kiss to Megumi’s abdomen, scrapes his teeth just slightly against the flesh. He looks up at where Megumi is standing above him with eyes that are glazed over, and licks a stripe from his pelvic bone up toward his navel.

“Take the towel off,” Yuji whispers, his breath warm where it hits Megumi’s skin. “Please.”

Megumi’s breath stutters a bit, betraying how he feels. He tries to remain nonchalant, focusing on running his fingers through the pink strands of Yuji’s hair, but he can’t help himself. Yuji is so cute like this—needy and desperate. Megumi likes feeling in control, especially considering how strong Yuji truly is.

“You take it off,” Megumi says, and Yuji immediately nods, wasting no time to pull the towel off his waist, letting it drop to the floor.

He licks the leftover blood off his lips as he stares at Megumi’s bare pussy, nestled in soft curls of dark hairs, before looking back up at his face. “Are you still bleeding?” he asks.

Megumi lets out something like a mixture between a scoff and a laugh. “Well, yeah. It’s not something you can just put a bandaid on, Yuji.”

“No, no, I know. I’m just…” Yuji blinks, tries to get his thoughts under control. He’s so fucking hard, and he can’t stop thinking about Megumi’s blood. It’s just there. He doesn’t even have to break the skin—he could have such easy access to it, if Megumi would just let him. “You haven’t put a tampon in, right?”

Megumi shakes his head. “Nope. Not yet.”

Yuji lets out a shaky breath. His fingers flex where they’re wrapped around Megumi’s hips, squeezing and trembling with barely concealed lustful desire. Megumi is so clean. Warm, and still slightly damp from the shower. Yuji’s mouth is watering.

“Good,” Yuji says. “That’s… good, Megumi.”

He tilts his head to the side. “Is it?”

Yuji nods. “Yes. Let me eat you out,” he says. But then he realizes how that came out, and he quickly corrects himself, “I mean– can I eat you out? Please?”

Megumi hums, pretending to think about it as he lightly scratches his fingernails over Yuji’s scalp. “Mmm, I don’t know, Yuji…”

Yuji presses his face back up against Megumi’s abdomen, inhales deeply, a soft groan escaping his lips. “Please,” he mumbles. “Oh, god, please. I’ll do anything.”

“You couldn’t even properly put the bedsheets away,” Megumi points out. “Which you literally offered to do, by the way.”

“I know,” Yuji says, and he sounds frantic, almost hysterical. “No, I know, but– please. God, Megumi, you’re driving me crazy. Your scent, it’s… I can’t fucking handle it.”

“Should I get the leash?” Megumi says, a sort of half-joke, to which Yuji lets out a soft moan.

Anything,” he says. “Anything you want.”

Delight surges throughout Megumi’s body in the form of electric vibrations, swirling in his chest and on his skin. Yuji is so in awe of him, so desperate, with a craving that he allows to remain completely unconcealed. Megumi is obsessed with Yuji’s blatant display of affection. It never fails to turn him on, every single time.

He leans down to pick the towel up off the floor and spreads it out on the mattress, next to Yuji. A preventative measure for what’s soon to come, as Megumi is evidently much more clearheaded than Yuji is—at least, for now.

“Show me how badly you want it,” Megumi says. He lays down on the towel and spreads his legs just a bit. Yuji will have to work for the rest.

“Yes,” Yuji breathes out, shuffling in the bed so he can kneel between Megumi’s thighs. “Whatever you say, Megumi. I’m yours.”

“Yeah, you are,” Megumi whispers, caressing Yuji’s jaw, running his thumb along the swell of his cheek. “All mine.”

Yuji turns his head to the side and presses a kiss to Megumi’s hand, then opens his mouth a little and lets his fangs scratch the surface of his wrist. Megumi lightly taps Yuji’s cheek with his palm and tuts at him.

“Ah-ah. I didn’t say you could feed from me, did I?”

“But–” Yuji inhales a breath. He looks down, where his lips hover just above Megumi’s pussy. “Let me…” he says. “Please. Need you.”

Megumi smiles—a genuine smile, adoring how open and honest Yuji is. “Get to work then.”

Yuji doesn’t need to be told twice. He hooks his hands underneath Megumi’s knees and places his legs atop his shoulders, turning his head to the side to press kisses along his inner thigh. Despite Megumi’s previous warning, he trails the sharp edges of his teeth along the surface of his sensitive skin, but he doesn’t break the barrier. Just light scratches felt through warm, heavy breaths, as Yuji’s grip gets tighter on his thighs and he begins to lose his sense of control.

His mouth trails up toward Megumi’s groin, and he presses his face into the trail of hair that leads down from his navel, letting out a soft moan.

“You smell so good,” Yuji says. “You’ll taste even better. I want to eat you whole.”

Megumi grips Yuji’s hair and gently leads him closer to where he’s already aching between his legs, a slight heartbeat in his clit, with wetness gathering below it.

“Do what you do best,” Megumi says, “and use your mouth for something other than talking nonsense.”

“It’s not nonsense–” Yuji starts to speak, but Megumi pushes his face down to shut him up. “Mmh.”

Yuji lets out a stifled whine when Megumi tilts his hips up, grinding his warmth against his face. Yuji presses his tongue against him and moans when he tastes the mixture of his fluids—arousal and blood combined into one. To Yuji, it tastes sweet, a testament to his vampiric senses, although he’s never known blood as sweet as Megumi’s. It drives him wild, and his cock is hard where it’s trapped against the mattress as he spreads Megumi’s legs wider and buries his face in his folds, plunging his tongue inside of him.

He focuses on the flavor more than anything else. Obviously, he wants to make Megumi feel good. But it’s hard to think about that when his scent and his taste surrounds Yuji completely, and all he knows in this moment is how wet and warm Megumi feels beneath his tongue.

Yuji creates a vacuum-like suction with his mouth and feeds from between Megumi’s legs, his fangs grazing over the sensitive flesh, causing Megumi to let out a violent gasp, legs shaking where they’re seated on top of Yuji’s shoulders.

“Holy shit,” he says, eyes wide with shock. “Yuji, what the fuck– are you really…?”

Holding Megumi’s body down with both hands, Yuji only increases his pace, muffled moans as he grinds his cock against the bed, euphoria filling his veins and twisting within his gut. The taste of Megumi is divine, like nectar of the gods. Yuji could live off of just this alone, and nothing else.

Megumi pulls at the pink strands of hair on Yuji’s scalp, a warning as his hips stutter against his face and he begins to let out sharp gasps, moans that teeter on the brink of overstimulation.

“Yuji– that– that’s enough,” he whimpers. “It’s too much. Just– normally, please, do it normally.”

Yuji extracts himself from the object of his desire and looks back up at Megumi. And what a sight that is—eyes wide, chin dripping with blood, hair mussed from the way Megumi was pulling at it. Megumi whines just from the view, but he has to catch his breath before Yuji makes any further movements.

“That felt kind of weird,” Megumi says, still breathing heavily. “Don’t feed from my vagina, you perverted freak. Just eat me out like a normal human being.”

“There’s nothing normal about me,” Yuji says, voice hoarse and airy as he leans down to press a kiss to Megumi’s thigh. “Not human, either. I want to devour you.”

Megumi finds it within himself to laugh, just a bit. “You’re crazy.”

“About you.”

It’s only two words, but they hold so much weight. Yuji doesn’t linger, he dives back down and presses his lips against Megumi’s clit, sucking hard, swirling his tongue around it until he has Megumi right where he wants him. His eyes fluttering shut, hips ticking up into Yuji’s mouth, as small, relaxed moans leave his pretty lips.

A few drops of blood drip into Yuji’s mouth without him even really having to try, and he licks them up greedily before inserting two fingers inside of Megumi, reveling in the way he gasps and instinctively tightens around the digits.

“Relax,” Yuji murmurs, but his words are smothered.

It’s good that Megumi thought to put the towel down, because blood easily stains the fabric as Yuji fucks his fingers in and out of Megumi’s pussy. Slick sounds and cute little whines leave his body the more that Yuji continues with his pace, fervent and desperate.

As his bloodlust was triggered, Yuji’s extended fangs keep scratching up against Megumi, but he practically welcomes the pain, pressing Yuji’s face down as he comes with a violent gasp. Yuji feels a small wet spot accumulating in his own underwear, impossibly turned on just from the sound, the taste, and the feel of his Megumi all splayed out beneath him.

Yuji doesn’t stop after Megumi comes. He chases his own high, ignorant to Megumi’s trembling thighs, the way he cries out each time Yuji sucks harder, presses his fingers in deeper. Yuji is grinding his clothed cock against the mattress earnestly, and he honestly thinks he might come just from this.

“Yuji,” Megumi gasps. “Yuji– please, please.”

Yuji lets out a muffled groan, thinks to himself, Keep begging me, keep saying my name just like that, all pretty like you always do, but he can’t speak. He feels a stinging pain at the back of his scalp when Megumi pulls him off, and he looks up at him with a dazed expression.

“Fucking hell,” Megumi says, chest heaving up and down. “I already came, Yuji, that’s enough–”

“One more,” Yuji begs. “Give me one more. I know you can do it, baby, you’re so perfect. Taste so fucking good, too.”

Megumi shakes his head, whining, but still allows Yuji to continue pleasuring him. His eyes are shut tight, jaw slack around silent cries and moans, while Yuji is completely in his own world. Megumi loses track of how long Yuji stays down there—even as he comes for the second time, Yuji doesn’t stop. Even as his jaw starts to ache and Megumi is writhing, whimpering beneath him, with his legs closed tightly around Yuji’s head, he keeps going.

When Yuji does stop, he sits up and immediately shoves his pants down, pulling out his leaking cock and slapping it against Megumi’s pussy. He rubs onto his clit, then down lower until his tip is nestled between the folds, wet and dripping around the head of his cock.

“Yuji,” Megumi exhales, feeling sweat rolling down his temple.

Yuji looks over at Megumi with a wild gaze, and what he finds in Megumi’s expression makes him moan, rutting against him harder, their fluids mixing together into something both heavenly and obscene.

Yuji’s fingers are still slicked with Megumi’s blood, and he brings them up to Megumi’s lips, smearing red across his mouth until he opens up and allows Yuji to thrust his fingers inside.

“Taste yourself,” Yuji says, breathless, as Megumi sucks his fingers clean. “This is what I go fucking crazy for.”

Yuji bites his own lower lip until it draws blood, licking into the wound with a feral growl. He taps the head of his cock against Megumi yet again as he says, “This is what you do to me, Megumi. Do you feel that?”

Megumi nods, moaning around Yuji’s fingers. His own blood doesn’t taste as good to his human tastebuds as it does to Yuji’s, but he still indulges in the sensation, lets Yuji essentially fuck his mouth with his fingers until drool is running down his wrist. When Yuji takes his fingers out of his mouth, he cradles Megumi’s cheek, his eyes feral and yet, simultaneously, still somehow so soft.

“Fuck me,” Megumi says, his voice raspy.

Yuji leans down and covers Megumi’s lips with his own, licking up the blood he smeared across his mouth and plunging his tongue inside, tasting the leftover flavor of such sweet nectar. He pushes himself inside of Megumi as he continues to kiss him, drinking down the gasp that Megumi breathes into his mouth.

Megumi is so warm and soft wrapped around Yuji’s cock. He swallows him up like it’s nothing, like they were made for each other, and Yuji fucks into him with a forceful, desperate pace. Just the wet sounds of Megumi’s pussy is enough for Yuji to shut his eyes tight and beg himself not to come too soon. He’s been on edge since before he even started eating Megumi out—since the moment he realized their bedsheets were stained with Megumi’s blood.

As he looks down at himself thrusting in and out of Megumi, he notices his cock is stained red with Megumi’s blood, and it drips out onto the towel beneath them. Yuji moans, watching the way he enters Megumi repeatedly, entranced by how he stretches around him, how his blood paints his cock. It’s more beautiful than any portrait he’s ever seen in all his years of living.

He circles Megumi’s clit with his thumb, and Megumi cries out, arching his body off the bed and exposing his throat as he tips his head back. Yuji can see the beat of his pulse, he can almost taste the blood the flows beneath his skin. He leans his head down and buries his face in Megumi’s neck, biting and sucking without actually drawing blood. He wants to drink from him so fucking badly.

Yuji could go all day like this if it weren’t for how weak he gets when he craves Megumi’s blood. His vampiric stamina means he can fuck Megumi for hours, but the promise of fresh blood—Megumi’s blood—being so close to his fangs means Yuji’s hips are stuttering, his lungs are begging for air, and his movements are turning choppy.

“Megumi,” he moans against his neck, slurring his words as he speaks. “Please, oh please. Want it. Want you– so fucking bad.”

Megumi nods as best as he can in the position he’s in, baring his throat further so Yuji can sink his teeth into the supple flesh. “Do it,” he says. “Fuck, Yuji, just do it. I want it too.”

Yuji is biting him before Megumi even has the chance to finish his sentence. The elasticity of his skin snaps underneath the pressure of Yuji’s fangs, and sharp, stinging heat spreads from Megumi’s neck, down toward his spine, and vibrating throughout his entire body.

As Yuji drinks from him, blood seeps from the wound in his neck and drips down Megumi’s sternum, Yuji’s chin getting messy with the red substance. Megumi feels like he’s buzzing all over from the intense sensation, head dizzy and ears ringing, breathing heavily against the top of Yuji’s head. He finds himself coming once again, and it’s borderline violent. Megumi’s voice is completely broken as he’s sobbing, quivering where he’s laid out underneath Yuji. All he can say is Yuji’s name, over and over again.

Yuji pulls away and presses down on the wounds with the tips of his fingers so they can heal, before he licks up all of the blood that managed to escape. His tongue swirls across Megumi’s skin, wet and warm, mopping up the mess he made, while he chases after his own orgasm.

“You’re so good to me, Megumi,” Yuji says, his teeth stained red. “Taste so good, just like always. Thank you, baby, thank you.”

Megumi just whines, unable to fully respond to Yuji’s praise. Yuji pulls out right before he’s about to come, stroking himself to completion as he spills all over Megumi’s pussy and lower abdomen. He breathes heavily, staring down at the way his cum mixes with Megumi’s blood, and it’s such a beautiful sight, he thinks he could come again just from looking at it.

Megumi seems like he’s already passed out, but Yuji knows he’s awake based off of the little grunts he does from each question Yuji asks him, like are you okay, and was that too much. He wipes Megumi down while peppering soft kisses all across his body, murmuring sweet words and thanking him over and over again for how good he was.

Yuji gently rolls Megumi’s body over in the bed so he can pull the towel out from beneath him and put it in with the rest of the dirty laundry. And while Megumi sleeps, Yuji brings the hamper down to the laundry room and throws everything in the washing machine before he walks over to the kitchen and starts making Megumi breakfast.

While Yuji no longer has the need for food, he’s still remembered how to cook, and he delights in cooking for Megumi, especially.

Megumi looks particularly gorgeous when Yuji wakes him up with a full plate of food and a cup of steaming coffee. He blinks up at him with those lovely green eyes, and Yuji grins, brushing the hair out of his face and pressing a kiss to his forehead.

“You made me food?” Megumi mumbles.

“Yeah, baby. You need to eat. I took a lot from you.”

Yuji winces as he says it, feeling guilty that he lost such control and fed from Megumi while he was already losing blood from his menstrual cycle. But Megumi only gives him a sleepy smile, making grabby hands toward Yuji so he can bury his face in his chest.

“Don’t feel bad,” Megumi says. “I liked it. Came so hard.”

“How did you know I–?” Yuji starts, but Megumi interrupts him.

“Because I know you. You always feel bad.”

Finally, Megumi sits up in the bed and allows Yuji to hand him the coffee mug. He takes a sip and lets out a small sigh.

“Thank you,” he whispers. “I love you.”

Yuji beams. “I love you too,” he says. “I love you so much. Now eat, before it gets cold.”
