Yami threw himself out of the cab and stormed up the white marble steps, pounding on the doors before he ducked in front of the doorbell camera to give it a vicious middle finger.

Fuck you, Kaiba.

He then turned around to face the gate when he felt his eyes heating up again with tears.

His self-control was slipping.

He told himself he wouldn't cry but it was getting harder and harder not to do.

He thought Kaiba was his friend—

Isono opened the door with a solemn bow, and Yami held his phone up which still displayed the ongoing call.

"Where…is he?" Yami breathed through gritted teeth, feeling a real tear curl down his cheek to betray him, but he swept it away quickly. "And who is it? He's been in a call with me for the past 15 minutes, fucking someone."

"Apologies. I don't know where he is," the manservant said with a frown. "Master Kaiba is… One moment please."

He straightened up stiffly to slip his hand into his blazer pocket, pulling out his phone to send Kaiba's phone a location request, and when it wasn't answered within 60 seconds, Isono's frown deepened.

Odd?

Master Kaiba had returned from work early today and hadn't left the house since.

Not that he knew of anyway…

The master would've alerted him before leaving.

"Let me in, or tell me where he is," Yami demanded, on the brink of losing it as he swallowed his rage in order to speak in full sentences.

Isono shook his head slowly and hastily accessed the GPS Master Kaiba usually wore on his sleeve and discovered the signal originated from directly beneath them.

Ah. The lab… in the basement.

And it was strange that Master Kaiba was taking so long when he said he'd only be down there for an hour today. By his count, it had now been three.

And he hadn't let a guest in since then.

The realization hit him particularly hard, and Isono shot his arm out to snatch Yami's phone out of his hand, shouting into it, "Master Kaiba, are you in danger?!"

Yami huffed and rolled his eyes, shaking his head. Yeah, in danger. Sure.

In danger of sticking his dick into someone else too much and then calling to gloat about it, in true Kaiba fashion—

"Send…. Yami, don't come down!" Came the strangled reply, and Isono's blood ran cold, and he shouted into the receiver again, his hand sweating on the back of Yami's phone.

"Sir?! …Master Kai—"

"GET YAMI—stay by the—DON'T EVEN OPEN THE DOOR!" Came the stressed shout, and Isono blinked rapidly, handing Yami his phone back with a frantic bow and turned to dash into the house, gesturing nervously for him to walk in behind him.

"Come. Come inside. He requests your presence," Isono mumbled, not bothering to give Yami a change of shoes as he led the spiky-haired man down a flight of stairs and they stood awkwardly side by side in front of the silver elevator doors leading down to the lab.

Yami huffed in annoyance and itched to hang up, but he stayed on, hearing the light gasping and a heavy sigh, followed by a furious, echoing shout, " finally. Fucking fuck off, piece of… fuck!"

The elevator doors opened and Yami kept the phone pressed to his ear, his irritation rising as Kaiba, sounding out of breath, panted into the receiver , "h-hey….s-sorry. Are you by the door? The surprise I arranged for you is ready."

Yami wrinkled his nose in disdain as the elevator sank lower and replied, "I'm in your elevator," just as the doors opened again to reveal a dark hallway and two sets of sealed entrances, with black film taped over the viewing glass.

Nice. Very secretive. A sex dungeon perhaps?

He didn't even know Kaiba had a basement like this.

Isono bowed and left him in the hallway, stepping back into the elevator and closing the doors with a tight whoosh!

Yami blinked in confusion. What?

"Excuse me?" Yami gazed anxiously up and down the hallway, his fear and anger rising. "Your servant just left me here. Open this door! Who is in there with you? I don't appreciate this kind of surprise—"

Kaiba shoved the door open looking disheveled, the phone to his ear while his tie swung messily off from around his neck, and Yami's gaze drifted to the side, his face twisted with hurt.

"Alright. You win," Yami admitted, his throat getting tighter the more he noticed details about Kaiba's unusually messy appearance. It looked like he'd just had sex. His brown bangs were mussed up handsomely, matted with sweat from lovemaking and his neck was damp, his cheeks were flushed, and his eyes were bright…with excitement.

Kaiba stepped out of the lab and closed the door swiftly behind him, his eyes gleaming with triumph as he tore off his tie and offered it up to Yami to use as a blindfold with one hand, hating how it was stained with a bit of semen, but whatever.

A surprise was a surprise.

"What. I don't want that as a parting gift. Leave me alone. We're done. Stop calling me, you're the worst," Yami recited in monotone, his throat still tight with emotion while he kept his gaze off to the side, unable to meet Kaiba's eyes.

"Okay yeah, yeah I am." Kaiba nodded enthusiastically, shoving the tie higher up underneath Yami's chin. "Please? I worked on this for…weeks. Right after you gave me a Valentine's Day gift, I was supposed to have this ready by White Day—"

Yami's eyes widened, and he gave Kaiba a rough but playful shove, almost shouting in his face, "well if this is how you repay me, I don't want it—"

"Yes, you do! Put this on around your eyes. Come on, I didn't almost just die for this," Kaiba reached forward to loop his arm around Yami's shoulders, struggling to get the tie on him like a blindfold, feeling Yami fight him weakly while hissing through choked sobs, "I s-said I'm breaking up w-with you!"

"And this is how I'm convincing you not to," Kaiba said desperately, his palms squishing comically up against the sides of Yami's cheeks while he felt hot tears soaking into knuckles, and his guilt came rushing up as he gazed into Yami's angular eyes which were shining with frustration.

"Or you've broken up with me, I don't accept that answer, here's my response," Kaiba added, gently inching the tie up around Yami's nose, seeing Yami blink at him once and swallow visibly. "I spent weeks making this. You caught me. You win, okay? Come see it."

Yami blinked again and closed his eyes for a fraction of a second longer, letting Kaiba push the tie up over the bridge of his nose and settle nicely over his eyelids. F-Fine.

Whatever the hell this stupid surprise was, he'd play along, and then leave if it didn't meet his expectations, which were now very high.

He was still 45% breaking up with Kaiba after this.

So this surprise ought to be grander than his grandest expectations.

The air was humid the second Kaiba led him in through the doors, and he wrinkled his nose at the strong stench of semen.

Okay, now he was 55% breaking up with Kaiba after this.

This surprise was supposed to be repayment for the silly Valentine's Day chocolates?

It had caused him grief instead of deepening their love.

He was now 65% breaking up with Kaiba after this.

"One second. Stand…right here," Kaiba pulled Yami over to stand right above the puddle of his own fluids, not caring how disgusting it was, but banking on Yami's pretty expression of incredulity and then admiring love for him when he laid his eyes on his rape plant.

"It reeks like your semen."

He was now 75% breaking up with Kaiba after this.

"Don't focus on that," Kaiba replied stiffly, ducking down to press a soft kiss to Yami's cheek before feeling a hand come shoving him away.

"Don't kiss me. We're broken up," Yami snapped, and Kaiba let out a laugh, ducking behind Yami's slender frame and hanging onto Yami's shoulders so hard, the tips of his fingertips turned white when he saw the plant spring to life, having smelled a new specimen to play with.

Yami grit his teeth in annoyance when Kaiba gave him a light shove.

"Take one tiny step forward."

I'm at my limit. I'm angry with him , Yami hissed through gritted teeth and was about to rip the blindfold off when Kaiba's hand came wrapping around his wrist, restraining him gently.

"Wait! Don't take it off yet."

Kaiba trembled with repressed laughter and anticipation while he eyed the plant wrapped around Yami's wrist, feeling him out for a struggle.

If Yami struggled a little…

That would be nice to witness.

"Kaiba, I've had it with you. This is no longer fun nor funny," Yami snapped, reaching up to his face to tear it off but feeling Kaiba's hand tightening so much around his wrist, he couldn't even move his arm. "Let go!"

Magic words! Kaiba crowed as he backed up so hard, his lower back bumped into the lab table, sending the cup of stationary clattering to the floor, so he hastily bent down to pick it up. When he lifted his head again, he almost keeled over at the sight of Yami struggling against the plant's vines, unable to shout because a thick strand had been shoved into his mouth and since Yami didn't bite down, it was thrusting in and out of his mouth with supreme lewdness.

Nice. Very nice.

Letting out a satisfied huff, Kaiba crossed his arms and kept his distance, smirking.

Now this was a victory.

Yami couldn't believe what was happening and couldn't hide his shock or sort out his feelings in time, because warm, familiar tendrils of something thick, warm curled around his upper arms, sliding down to snap his elbows together with force while something hot and damp shoved down the front of his pants to give the head of his flaccid dick a tight, choking squeeze through his underwear before dipping down lower to give his balls a fiery lick, while other parts of him were being slowly stripped and any inch of skin that was exposed was given a playful prod before the vine lost interest and crept over the front of his chest to find his nipples.

He opened his mouth to shout at Kaiba to take the blindfold off so he could see it for himself, but the second he did, a slimy appendage slid into his mouth and began thrusting in and out, dragging the tang of Kaiba's semen along the roof of his mouth, making his stomach curl at the taste he missed…so much…

Oh hell. Kaiba had his turn here already.

This was what he'd been doing on the call!

And this was why he'd been acting so skittish, like he'd been seeing someone else.

He'd been…fucking the plant!

Or…training it?!

Because one tendril was stroking his erection with the same intensity and speed Kaiba would use with his hand.

Melting into the warm waves of joy, Yami's legs trembled, and he tried to draw them together, but the vines kept them splayed apart, giving it access to his balls and hole, and one slid up his crack with frightening familiarity, giving his hole a tantalizing lick, making him let out a muffled cry.

Kaiba drummed his fingers against his arms, smirking to himself while enjoying the sounds of Yami's muffled gasps. He held a hand up playfully to cup his ear. "What? We're …what? Did you say we're—Oh, we're broken up? Then I think I need to leave you here for the next… I don't know , 24 hours? While you reconsider that? Hm? "

Yami struggled weakly and felt the blindfold shift across his eyes, giving him a peek of light strips in the beige ceiling above.

O-Oh hell…

This was the devious sex plant from the museum.

Kaiba had managed…to steal it?

For them as a White Day gift…?!

H-How thoughtful!

Yami threw his head back and leaned into the wonderful sensations, extremely aware of Kaiba watching him and it made him hot all over. The vine lavished the space between his asshole and his balls, thudding wetly along the softness until he squirmed and felt it slip higher up inside him, making his breath catch in his throat when it stretched his hole with agonizing slowness, and Kaiba's voice echoed through the lab, making him shiver inadvertently at the tone.

"Am I horrible at reciprocating? Tell me."

Yami's voice caught in his throat when the vine slid sinfully around his shaft and gave it a teasing up and down rub, making him curl forward and double over with an orgasm so sudden, he swore his heart stopped for a full second before he came back down, his ears rushing with a strange sound while he focused in and out at the shiny tiled floors beneath him while his body burned.

I-Incredible…

He's not even listening , Kaiba thought sourly, daring to walk forward and reaching out to grab Yami by the only part of his upper arm that was exposed, and pulled him down to press a kiss to the bridge of his nose, feeling the vine curl away playfully to give him access to soft lips, so Kaiba sank into Yami's kiss, his tongue tangling lovingly with Yami's weak thrusts, making him smile triumphantly.

"You like my present?" Kaiba asked again, wanting to hear it spoken aloud, and to his rising glee, Yami could barely open his eyes through the haze of pleasure as he nodded weakly and sagged forward against the vine restraints that kept playfully wrapping around the head of his dick, giving it intermittent squeezes that would make his body spasm while Kaiba watched.

"Are you still breaking up with me?" Kaiba prompted, seeing a vine come darting for his neck, and he swatted it away with the back of his hand, talking to it irritably. "You don't want me. Play with him instead."

And Yami felt the vine tighten around the tops of his thighs before one tendril slicked up his asshole again and thrust thickly into his hole at a relentless pace, making him want to pull his knees together, but he was kept flat against the glass tank, no longer feeling cold because fire was burning along his skin as Kaiba trailed his fingers up and down the center of his bare chest, gloating. "I'm a man of my word. Now say you want me to do it to you. Come on. I want to hear you say it."

Yami grit his teeth and let out a furious hiss, pulling his arms against the tight restraints as he growled, "yes, do it to me until I forgive you."

"You haven't forgiven me?!" Kaiba took an incredulous step back before he surged forward with fury and unzipped himself, reaching down to grab a palmful of Yami's thigh, pushing Yami over onto his side while his body was engulfed with the mass of vines, his fingers moving with a frenzied desperation.

Yami let out a nervous cry when he felt cold fingers pry the appendage off from around his leg and slide it out of his hole so forcefully, the warmth left his insides and made him shudder, but he was quickly filled with Kaiba's length as Kaiba pushed him against the side of the glass tank and breathed in his ear, the heat sending a tingle down his spine along with Kaiba's words, "….how about now?" And he began thrusting into Yami's hole with reckless abandon, enjoying the heated threads of pleasure snaking down his body as Yami let out a ragged gasp and curled his fingertips around the nearest vine to hang on while his body was rocked with vicious thrusts.

His mind went numb with joy, and Kaiba's hands flashed in his vision briefly when they raked down his chest, pushing away a few appendages that snaked away and curled around Kaiba's wrists instead, and Kaiba didn't seem to mind. He leaned into it to shove his tongue into Yami's half-parted lips, enjoying the way Yami had gone limp underneath him and only responded by moving the tip of his tongue in a lazy swirl against his demanding prods, and his eyes would flutter open sometimes, they'd make eye contact briefly before Yami would close them blissfully again and melt into the heated warmth, enjoying every small ridge and curve along Kaiba's dick as it slid in and out of him, teasing him, encouraging his breaths to quicken as he came to another emotional high and his body clenched with a rough heave, his ears humming and his blood rushing to his face while he orgasmed all over the front of his stomach.

Kaiba leaned his head down to land a possessive bite to Yami's collarbone, still egging him on for verbal confirmation while fluids dripped lewdly down between Yami's legs, even getting some on the fronts of his thighs.

"Rate this present on the list of presents you've ever gotten in your entire life."

Yami let out a strangled laugh and felt the vines slide off his body, leaving him a bit cold, but Kaiba held him gently in his arms, keeping his chin hooked strategically over his shoulder.

Can't feel my…arms and legs , Yami lamented as Kaiba draped them around his shoulders and carefully walked him over to the couch at the far end of the room. There was a light shuffle, followed by a thump of a blanket thrown down over the cushions and then Yami was laid down upon it, completely spent.

Drained, from the assault of multiple orgasms.

Kaiba sank into the cushion beside Yami's slender legs and patted the tops of his thighs, grazing his knuckles playfully against the top of an adorable flaccid length, pleased when Yami didn't even react to that when usually, his hand would be swatted away.

Yami laid there, his face angelic, framed nicely by the spiky blond bangs while his eyes remained closed, and Kaiba gave Yami's bare knees a nudge.

"Hey. Speak."

Yami's eyelids fluttered as he threw an arm over his damp forehead and tried to catch his breath.

"I'm… That was incredible…" Yami managed, his tongue numb from the kissing. His lips numb from the way Kaiba had been nibbling playfully on them.

"It's not even fully matured yet," Kaiba replied conversationally, wanting to hear more praise. "I was aiming for White Day. So that's what I've been working on. It needs constant care so the vines can grow and extend properly."

Yami could only nod.

His heart had swelled wonderfully with joy and he was trying to calm down.

Kaiba had reciprocated in the best way possible.

"So… You should come over and help me grow it until its at a size we both like," Kaiba said with a gleam in his eyes, and Yami let out another weak laugh, struggling to sit up and finally managing to do so.

He leaned forward to drape his arms lazily over Kaiba's slender shoulders and bumped his forehead playfully against Kaiba's brown bangs, dipping his lips down to capture Kaiba's lips in a tender kiss and falling into the delicious pangs of lust that rose up anytime he tasted the coffee at the back of Kaiba's breath.

It accompanied a wave of overwhelming relief.

Kaiba was thoughtful and sweet in his own way, and everything about him was perfect.

Good to know the present of surprise handmade chocolates hadn't scared the CEO away.

THE END
