"Nii-sama."
He likes a cup of coffee after a good fuck. Strong, black coffee. It doesn't faze him in the least that there's a thermos filled with coffee, right temperature, right taste, on a metallic platter on the small table next to his comfortable chair. He's used to his personnel moving in and out quickly and silently.
"Nii-sama."
If he were a smoker, Kaiba Seto would have lit a cigarette, just to enjoy the taste. Just to cherish the moment, even though he doesn't do cherishing, of anything. Savor it, maybe. Savor the taste, and hold on to that feeling of satisfaction and...completion. Accomplishment.
"Earth to nii-"
"I heard you the first time."
He tilts his head to look at his brother, who didn't bother to throw on a bathrobe. It is strange to see Mokuba all grown up; for some weird reason Kaiba had believed his brother would stay thirteen forever. How long had it been since they celebrated his eighteenth birthday...three weeks ago? Still, his younger brother's face lights up like a kid unwrapping its Christmas present, and he all but jumps into Kaiba's lap.
It is a good thing his cup is already empty, otherwise he would have spilled all over Mokuba's skin; sighing, Kaiba moves his hand to put the cup back on the table. As he does so, his eyes catch sight of the bed. The completely disheveled bed, with sheets and covers rumpled and wrinkled, stained and smeared. Two pairs of feet are visible, and Kaiba simply grimaces.
Yuugi is on his side, one hand tucked under his head, a smile on his lips. It doesn't surprise Kaiba to see Yuugi's Other, or Yami as he goes by that name for some obscure reason, have his arm wrapped around him. Their hands are entangled, fingers laced together. Ever since he managed to get a solid body- Kaiba didn't care to ask, and he still doesn't care to this day- both Yuugis have been inseparable, a unity transcending every aspect of life and death.
It makes him feel strangely empty. Because Kaiba knows he can fuck Yuugi as many times as he wants and make him scream and beg and cry and plead, but it's still Yami he'll curl up to. It's Kaiba's name that rolls over his lips, begging whorishly for harder, for more, but it's still Yami he'll search out and only accept his arms around him.
Mokuba knows better than to ask, but follows his brother's gaze and smiles, albeit a little wryly.
"They're cute together, aren't they?"
He doesn't answer. 'Cute' isn't exactly something that comes up in his mind when thinking of them, seeing them. Not that Kaiba really bothers or wastes time thinking of them...thinking about them, of course. Cute? No. Sick. His grimace turns bitter. Yuugi is a lovesick idiot who will follow his Other, this Yami, until the end of the world, throw himself at his feet and do everything that he wants him to do, even if it is spreading his legs for his worst rival, his enemy, and beg for him to take him hard and make him come. Yami is a manipulating, lying son of a bitch with red eyes who takes and takes and never gives. It was his idea, Kaiba is sure of it, it was the idea of the former-Pharaoh-turned-Spirit-turned-human who is used to getting his way, any and every way, to maneuver them in some sort of position that they ended up in bed with each other.
"Nii-sama?"
He didn't mind, though. Yuugi is easy to take and easy to please. It wasn't until another one of their get-togethers that Kaiba found out that he actually likes to please him, large violet eyes almost shining up to him with gratitude. In some moments, when he's alone and not bothered by meetings and conversations, Kaiba actually likes to think that he's better to Yuugi than his Other, who he suspects of some kind of cruelty; the way Yuugi looks at him for approval for everything he does, be it from sucking cock to accepting a drink.
Shifting in his chair, Mokuba puts his head on his shoulder and wraps his arms around him. He just sits there, enjoying the silence after a busy night. He's young and has good stamina, just like the others- Kaiba was sure that only Yuugi was really asleep. Yami would watch over him and grant him his sleep, to his conditions and regulations. His eyes were closed, those red piercing eyes that gave him such weight, such personality, such grandeur.
"Would you like some more coffee?"
Mokuba whispers, as he's respectful to their guests and doesn't want to disturb their sleep. There's still so much his younger brother has to learn, except for pure physical pleasure only. Kaiba barely touches him, doesn't return the hug. He cares for his brother, but not like that. They share their partners, not each other. Mokuba likes Yami, and Yami likes to watch Kaiba and Yuugi. With those red piercing eyes that gauge him with every movement.
"I've had enough, thank you."
Enough of coffee. He didn't have enough of his...partners. Yuugi, the easy go-around who smiles and hugs and cuddles as he's being fucked, and Yami, who is silent, hard and arrogant in his belief that one day he will get to fuck Kaiba himself, not only his younger brother. It almost makes his grimace turn into a grin. Mokuba happily hugs him, the bond between brothers strong.
Maybe one day, Kaiba thinks, maybe one day he will have Yami under him and will make him beg and plead, cry and scream. He already knows that he will be curling up with Yuugi afterwards, call him 'aibou' and lace their fingers together.
Four people, two pairings. When breathings are erratic, when legs are spread and hips are lifted, when sweat rolls over hardworking backs and cocks are slick and pumping, they are still four people and two pairings. There is no union underling, no bond between any of them but the pairings. Kaiba doesn't know whether to be jealous or annoyed. He doesn't care for anyone else but his brother, and the two Yuugis are just what they are...
...whatever they are.
One day. He might understand.
