Chapter Text
You would have never known that today was Ruki’s birthday if Azusa had not casually mentioned it at dinner. There were no gifts, no special birthday dinner, no cake, no decorations, no party. It had been a completely ordinary day.
The more you thought about it, the more it made you sad. A birthday should be special. Everyone deserves at least one day a year to be, at least a little, spoiled by their friends and loved ones. Although he never complained, Ruki clearly worked so hard day in and day out. He deserved a treat. But with the day practically over it was too late to get him the gifts that he deserved.
You meandered over to the library, where you knew Ruki would be reading. Sure enough there he was, sitting elegantly in a wingback armchair, an ankle perched across the sharp corner of his knee. You couldn’t tell what he was reading but it was in a slim red volume with fluttery white pages. He didn’t acknowledge you as you stepped into the room, tentatively approaching him.
“Ruki?” You called softly, afraid to break his reverie. He turned a page, the soft rustle of paper the only sound.
“Master?” You tried again.
“Yes, Livestock?” He answered, not looking up from his novella.
“I didn’t know that today was your birthday. I’m sorry that I didn’t get you a gift.”
“It’s quite alright. Vampires don’t celebrate such trivial things as birthdays.” You want to point out that he was human once too, but you bite your tongue.
“Even so, I would have liked to celebrate it with you.”
“And why should I care about what livestock wants?”
You had nothing really to say to that. You let the silence linger, unsure if you should stay.
“Is there a reason why you've interrupted my reading?” Ruki presses, eyes still focused on the page before him.
“Well, I was hoping we could celebrate now,” you say, desperately searching for a sign that he’s interested. He flips another page. “Fine, as long as it doesn’t disturb my reading.” You realize: he isn’t uninterested. He’s issuing a challenge.
Approaching his chair, you sink to your knees in front of him. You lay your head against the crook of his knee and Ruki immediately uncrosses his legs, making room for you between them. Keeping your touch light, you slide your hands up the back of his calves. Pressing a kiss to his clothed knee, you begin to run your hands up his thighs, trailing kisses in the wake of your fingers. Ruki shifts in his chair, but doesn’t put down his book. Reaching his belt, you undo the metal fastening. The soft clink sends a shiver down your spine. You unzip him and are surprised to find he’s half-hard.
“Happy to see me?” You quip, looking up at him.
“There are better uses for your mouth, Livestock. Suck.”
Obediently, you give the head a slow lick, trying to coax him into full hardness. You continue licking, making your way down his hardening shaft until you reach the root. In one long, wet lick, you drag your tongue from the base to the head, earning you a shudder. Peering up at Ruki, you search his face for any other kind of reaction.
Ruki reclines easily in his chair, eyes still focused on the book in his hand. His other arm drapes itself across the arm of the chair, fingers drumming against the stuffed fabric. You’d have to work harder.
Now that he’s fully hard, you take the tip of his cock into your mouth. Making sure that you use a lot of saliva, you begin bobbing along his shaft, taking more and more of his dick into your mouth the further down you go. You keep your tongue along its underside, using it to massage along the thick vein there. On the withdrawal, you seal your lips around his cock, making sure that he feels their wet, insistent pressure as you travel back up his shaft. You lose yourself for a moment, trying to keep a steady, consistent rhythm. A small sigh escapes from him and your eyes dart upwards, desperate to catch his expression.
Although his book remains open in his hand, Ruki has long abandoned it, allowing his eyes to drift shut. His head rests against the back of the chair, where he takes deep breaths in through his nose and out through his mouth. His free hand clutches the arm of the chair, its grip firm. Sensing your attention, his cobalt eyes snap open, skewering you as you pleasure him with your mouth. Maintaining eye contact, you sink down him even further, swallowing around the head of his cock as it enters your throat. Reaching the base, you give him a hard suck and he finally moans, weaving his fingers through your hair so that he can hold you against his pelvis.
“Such good livestock,” he breathes, thrusting gently into your mouth. You choke briefly around him and he grunts, easing his grip so you can back away slightly and regain your composure.
“I won’t punish you too harshly,” he promises, pushing your head back down his length. “But you did interrupt my reading. You’ll take ten thrusts and you’ll swallow every drop of my cum. Understood?” You hum around him and his fist tightens in your hair.
Ruki guides your head along his member, counting out each thrust he sinks into your throat. You dutifully swallow around him, keeping your breathing steady and your throat muscles as relaxed as possible.
“1, unnh.
2.
3.
4, hngh.
5, fuck.
6.
7.
8, shit, Livestock.
9, fuuuuck,
10, ah!”
You pop off of him, gasping for air. His member shines with your spit, twitching with pleasure as you catch your breath.
“You’ve pleased your Master, Livestock,” Ruki says, his voice haggard. You quickly return to his cock, sucking the angry purple tip. You frantically run your tongue along the ridge of the head, trying to keep up the momentum. You return to bobbing along his shaft, drooling down his cock. “I’m gonna come,” Ruki says. You take him in as far as you can and he comes, releasing down your throat, cock twitching as he orgasms. You swallow everything he gives you.
“Come up here,” he pants, tucking his spent cock away. You climb into his lap and wrap your arms around his neck. He returns your tender embrace, locking his hands around the small of your back. He mouths along your neck, ghosting his fangs along your throat. Cupping your face in his large hands, he kisses you slowly, deeply.
“Happy birthday,” you murmur when your lips finally separate. Smirking, he says: “If this is the gift you had in mind, I suppose I don’t mind celebrating. Now let me show my Livestock how much I appreciate their thoughtfulness.”
