Immoral Behaviour


~ * ~ * ~


Part 01

Jou walked up the stairs, stopping in front of the mahogany doors of the elaborate Kaiba Mansion, his fist hesitating as it poised to knock. ‘Just what the hell am I doing here anyways? How did I let Mokuba talk me into coming here?’ He thought apprehensively. ‘Oh yeah that's right, he said that he needed help with his homework since Kaiba had a late meeting and couldn't help.’ The blond gave a sigh of defeat as he knocked on the door, only to jump and yelp in surprise as it immediately opened.

Mokuba stood in the doorway with an amused expression on his face. The twelve year old grinned as he grabbed Jou's hand, dragging him inside and out of the cold. It had been snowing recently, covering the land in a large blanket of soft, white powder.

After divesting the blond of his coat and shoes, the young Kaiba lead his guest throughout the mansion proper. They stopped when they reached a room similar to the living room they had passed earlier, but smaller and with a different atmosphere. It was less ornate, with furniture suited to a more casual lifestyle.

Mokuba gestured for him to sit on the large couch, then walked away for moment, leaving his guest to bask in the warmth of the fireplace. Quietly closing the door to the room, he swiftly returned, depositing himself in Jou's lap. Before the blond could protest or ask 'Why', the raven-haired boy leaned forward, planting a firm kiss on his lips and cupping his crotch, gently squeezing the prize within his palm.

Jounouchi, stunned when Mokuba sat himself in his lap, opened his mouth to protest, the smaller boy‘s lips connected firmly with his own cutting him short. ‘What the hell does he think he's doing?’ the blond thought to himself, eyes widening in shock at the feeling of Mokuba‘s hand on his crotch. But Jounouchi could only moan, giving Mokuba the opportunity to deepen the kiss and returning it with equal force. That little hand rubbing against his stirring arousal refusing to give him time to think about why he was allowing this to happen. However, the jolt of electricity that was sent from the contact put his mind in a buzz, leaving all thoughts on the back burner for the time being.

Bringing his hands up to the diminutive boy's head, Jounouchi entwined the silky, raven threads in his fingers, mentally debating his situation. ‘Why am I doing this? This is so wrong. If Kaiba knew I was doing this with his little brother... I don't even want to think what he'll do to me. Never mind that his little brother started it all.’

Liking the blond's reaction, Mokuba moved to undo the fastenings of Jou’s jeans. Shifting the boxer shorts aside, he grabbed Jou's hardening cock and stroked it into a rather turgid stance.

Moaning in appreciation at the rapturous contact, Jou wrapped an arm around Mokuba's waist. Pulling the other boy's head closer with the hand still in his hair, he deepened the kiss once again. As he assaulted the little minx's mouth, Jou began to arch towards the tiny fist that applied the glorious friction to his straining manhood.

"That's right Jou, just relax and enjoy. Besides, you have a surprise coming to you my Golden God." Mokuba thought, smiling as he continued the onslaught, making the blond wild with need.

They were so engrossed in their little passion play, that neither one noticed the brunet entering the room until he spoke. "Well would you look at what the dogs dragged in," Seto commented in a sultry tone, as he leaned against the back of the couch, wrapping his arms casually around Jou's shoulders. "And to what do we owe the honour of your presence Puppy?" He asked in the blond's ear, leaning in to lick delicately at his right earlobe.

‘Oh shit, oh shit, oh shit,’ Jou thought, yelping in shock and with more than just a little fear at the CEO's sudden appearance. ‘Oh Kami-sama, I am so dead meat. Wait a minute, hold the phone, is he...is he kissing me? HOLY SHIT! SETO KAIBA'S KISSING ME!!! I can't believe he's actually..."

Jou lost what little bit of coherency he had left when both of the Kaiba brothers broke their kissing caresses long enough for Seto to pull the Golden Puppy's shirt over his head, discarding it unceremoniously to the floor. While Mokuba returned to plundering the depths of Jou's mouth, Seto attacked the tender flesh of his neck.

Jou, melted into a stimulated puddle, started to moan deep within his throat. Throwing his head back, he allowed the brunet more access to his neck, growling in disappointment when the contact ended. ‘Well...at least Mokuba didn't stop,’ the blond thought, feeling the boy's continuous, rhythmic pumping of his over sensitized member.

Relinquishing the blond, Seto moved to sit on the opposite end of the couch. He reclined against the side arm, propping his right leg so it rested on the back while the other dangled over the side. The brunet then unclasped his dress pants, never once taking his intense blue gaze off his brother and the Puppy, as he pulled down the zipper releasing his engorged flesh. "Mokuba, come over here," Seto called to his little brother in a barely controlled voice.

Hearing his brother call his name and beckon him, Mokuba pulled away from Jounouchi and crawled over to Seto.

Growling in frustration, Jou opened his eyes slightly just in time to see Kaiba whispering something in his little brother's ear, before both of them parted, giving each other a very feral grin. ‘What the hell are they up to? And why do I have the strangest feeling that I'm their hunted prey?’ Jou thought to himself as he watched the two closely, only to regret it the next moment.

Sliding down the brunet's torso, stopping between his legs, Mokuba nuzzled the turgid flesh of his arousal reverently, before taking it to the hilt within his mouth. Pausing only a moment to adjust, and to savor the moan of pleasure that escaped his brother's throat, he then began a rhythmic series of sucking and swallowing motions that sent Seto in a haze of ecstasy.

He watched as the younger Kaiba sucked his brother off, causing the elder to throw his head back in rapture. Hearing the delicious sounds emanating from the two, Jou could only groan at the erotic display before him. ‘What the fuck is wrong with me? Why am I getting off on this? I know I've wanted Seto for sometime, but now I want Mokuba too?’ He wondered to himself.

The blond was just about to go insane with lust, watching the two of them together when a smooth but throaty tenor cut off his mental tirade. "Jounouchi, why don't you quit your staring and come here," Seto ordered, running a hand through his brother's hair, caressing the raven locks tenderly as the boy continued to suck his cock with fervor.

"What? Why?" The blond inquired.

Reaching over, Seto grabbed the back of the blond's neck, pulling Jou over until he was straining to keep from crushing the little boy in Seto's lap as the brunet brought them face to face. "Because I want you to fuck my little brother while he continues to blow me," came the blunt reply. Seto leaned forward kissing the blond's rosy lips, still flushed from the earlier assault his little brother delivered.

Too caught up in the heat of it all, and not really wanting to back out, Jou conceded, leaning forward to give the brunet a lingering kiss. He gasped in shock at the electrifying contact, as Seto pulled away from the kiss.

Taking Jou's right hand, he suckled the first few fingers, worshipping the slender digits until they were nice and moist. Popping the fingers out of his mouth, the brunet gazed into lustful brown eyes as he spoke softly. "Try not to hurt him too bad. He may like you, but if you hurt him so help me god, I'll make you sorry," Kaiba claimed as he laid back, allowing the sensations his brother wrought to course through his body.

Groaning in barely constrained passion, Jou brought his hands around Mokuba's waist to divest him of his jeans and to position him for penetration. Bringing his right hand down in between the boy's milky thighs, he separated the firm globes, rimming the lad's pucker with his forefinger before inserting it into the ring of muscle. As he worked his finger in and out, he gently stretched the area until he was eventually able to insert two of his fingers to the knuckle.

Positioning himself at the raven-haired boy's entrance, Jou took one last look at the display the two made before entering the boy slowly, groaning in over-sensitized euphoria. Entering the boy's anal cavity half way, Jou began a series of small thrusts until he buried his massive cock in the boy's ass to the hilt. Once buried deep within Mokuba's anal recesses, Jou stopped, taking a moment to allow the boy to adjust to having his body, and to take survey of the two brothers. He didn't have long to wait and observe though, as a rather demanding voice reached his ears.

"God damn it Jou, just fuck me already will ya!" Mokuba declared in exasperation, making Seto burst into laughter as the blond's jaw dropped in shock of the boy's exclamation.

"A bit anxious now are we? Don't worry, now that I know how bad you want it, I'll be sure not to go easy on ya," Jou stated as he began to languorously move in and out of the tight sheath that consumed him. Hearing the boy moan in delight, and consequently Seto as well, Jou began quickening his pace. His ultimate goal now was to make Mokuba scream in passion, as he fucked his sweet ass to oblivion.

It took Kaiba all he had to hold back his impending orgasm, as he watched the blond Adonis ram into his brother. He needed to hang on for just a bit longer, but by the burning feeling in his gut, he knew that he was losing his restraint.

Jou in the meantime wasn't as fortunate, as his orgasm hit with a force so sudden that he ground his teeth in an effort to gain some of his lost control, grunting loudly as he released hard against Mokuba's prostate.

Mokuba on the other hand was overcome with sensation; the combination of Jou coming in his ass, and his brother's lenient control finally giving way, causing Seto to release within his mouth with a grunt of appreciation. At that moment Mokuba gave a wail of ecstasy, collapsing on his brother limply and falling fast asleep.

Pulling out of the small boy gently, Jou reared back, landing sprawled out on his back on the couch. Panting from the erotic play he had been coerced into. Not that he minded really. It's just, wasn't Mokuba a little young to be doing anything of a sexual nature. Before he could travel down that road of thought, a movement had caught his curiosity.

Sitting up from his position, Kaiba gathered his little brother in his arms before standing up and addressing the blond lying like a lazy dog on the couch. "I'm taking Mokuba to his room, you better be here when I return Mutt, or there will be hell to pay." Kaiba declared, turning and exiting the room.

Jounouchi sighed, covering his face with his left arm as the brunet vacated the room, leaving him to his thoughts, traveling back down the path he had just retreated mere seconds before the CEO's departure. Did Seto and Mokuba do stuff like that together on a regular basis? If so, that would explain the Mokuba's knowledge. And if they did, Jou wasn't one to fault them for it, hell, it's their business not his. But… Why include him into the scenario?

He didn't have too long to contemplate on those thoughts though, as he felt a sudden weight upon him. He moved his arm slowly, gazing upon the most beautiful azure eyes he had ever seen. Jou expected a blow to the face, but was taken completely of guard when the brunet’s lips met his in a passionate kiss. It was so sudden, that it stoked the fire in his loins all over again, giving him an instant erection with the intensity portrayed within it. Jou returned the kiss enthusiastically, encircling his arms around the Seto's torso. He then started at the unexpected feel of the slender fingers as they wrapped around his hardened dick, smearing the small bead of pre-come that collected on the head of his penis.

Jou arched his back gracefully, moaning softly as he felt the featherlike caress of the other boy's fingertips sliding up his cock. He opened his eyes as he felt the body on top of him shift; watching his cock disappear within the warm confines of the brunet's mouth, not leaving even an inch in its wake as he swallowed it to the hilt. Jou threw his head back against the armrest of the couch, closed his eyes tightly and screamed out in absolute bliss.

As he sucked the beautiful piece of flesh, giving it a few worshipful licks, Kaiba quickly lost his control, deciding that he needed the blond Adonis, and that he needed him now. Letting the hardened shaft fall from his lips, he quickly climbed up the blond's lithe body. "Jou, I need to be in you, now," Kaiba had claimed in a licentious voice, gazing into the lust filled amber eyes of his prospective lover.

"Unnn, gods Seto, yes take me now. Please," the blond begged, wrapping his legs around the brunet's waist in anticipation of feeling Seto's cock buried deep within his most private of places.

Pulling back, Kaiba began to help the blond remove his jeans, tossing them to the floor in haste. He then reached over between his body and the couch, where he left the tube of lubricant he brought on his way back from Mokuba's bedroom. Opening the tube, he squeezed out a liberal amount of the water-based content, chucking that as well when he was through. Reaching down, he wrapped his hand around his cock, coating both his erection and his fingers at the same time as he pumped the flesh in his palm.

Jou growled in impatience, he was hard and he wanted something, anything to relieve the pressure that was building in his groin. "Kaiba... Please," Jou pleaded, trying to rub himself against the brunet, in hopes of gaining some friction.

Sensing the other teen's discomfort, as well as being acutely aware of his own, Kaiba spread the Jou's legs further, pulling the blond down the couch towards him more as he situated himself at his entrance. Raising the golden-haired boy's hips a little, he was at the perfect position for maximum penetration. Pushing forward, Kaiba began to enter Jou's body, hissing in a mixture of pleasure and pain as his cock became slowly engulfed in his tight sheath. Loosing control of the situation, the young executive thrust his hips quickly, burying himself to the hilt within the blond beneath him, only to realize his mistake a moment later when a howl of pain tore from Jou's lungs. The boy was so fucking tight. Was he a virgin perhaps? Smiling with the given prospect, Kaiba bent over to kiss him apologetically, before starting to move in and out of the warm body of his recent obsession, wringing a moan of pleasure out of the boy as he continued to move within him.

Sweaty and panting from their exertions, it didn’t take long before both boys started to feel the fires of passion burning within their souls, succumbing to the inevitable as they arched in a silhouette of rhapsody, screaming in absolute euphoria as they reached their climaxes. One spilling his essence within, and the other one anointing them both as he came in between their joined bodies, leaving them both panting and flushing with the aftermath.

"Holy fuck... We'll have to do this more often," Jou claimed in a hoarse alto.

"Hn. You can say that again," Kaiba said as he lay against the blond.

Shortly thereafter, both boys fell asleep, exhausted from their wild festivities.
