The room is hot.
Sasuke has been gone for hours. Before his leave, he turned up the basement furnace. In the middle of summer.
Itachi would strip his clothing, or at least the bedding, if he could. But Sasuke has also gotten particularly fond of knots. Itachi doubts his brother would appreciate having his craftsmanship destroyed just so he could get comfortable.
Which leaves him miserable, with sweat trailing down his neck and his clothes clinging against his skin. With a sigh, Itachi decides the best way to endure is to calm his mind.
An hour later, his toes are dragging the sheets, his knees buckling inwards. Inner peace is typically easier found without a vibrator inside him.
.
When Sasuke returns from his downtown stroll, their house is at the degree of a sauna. He sets down the paper bags and drinks in the sight of his brother helpless on the bed. Itachi's lips are parted, raw, tender, and tinted with the same flush of his cheeks. Tendrils of hair lap down his shoulders, which have dropped down in surrender to the binds above.
Sasuke eyes the rope fastening Itachi's wrist to the headboard, and realizes with satisfaction that his brother has not touched it. His trip went longer than expected, and Sasuke thought Itachi would have cheated by now.
"Nii-san, I'm back."
Itachi looks up, dazed from the heat. His lips pull into a strained smile. "It's hot."
"I brought water."
Sasuke presents a cup. The rim is soon replaced by his own mouth, as he crushes their lips together.
His fingers tangle into Itachi's hair, pulling him closer. Itachi writhes underneath before releasing a low moan.
Sasuke chuckles. "You're awfully eager today." He pulls aside the comforter to reveal Itachi's body drenched, clothes obscenely pressed against every inch of his skin. He smirks at the erection straining under the fabric of Itachi's pants and gives it a squeeze.
"You left me here for over three hours with a vibrating dick up my ass." Itachi shuts his jaw when Sasuke strokes him again, then breathes, "What else did you expect, little brother?"
"That you'd enjoy yourself."
Itachi is hard to the point of desperation. He presses back against Sasuke's touch, his legs pulling in, only to snap his eyes open when Sasuke pulls away.
"No," Sasuke whispers. Above, he has finished unfastening the ropes, freeing his brother's last constraints. "You don't fight, nii-san."
At these words, Itachi swallows, as his shirt is tossed away and his hands drop limp. The area around his wrist is burned with chafe marks, his fingers still numb from the lack of circulation.
Sasuke kisses them once, before moving to his lips. With every taste, he can feel Itachi's fervor, throbbing with the desire to be touched.
But slowly, Itachi surrenders. His body falls lax under Sasuke's weight. The trembles in his breaths smooth away with every exhale.
Sasuke bites his earlobe. "Better." He knows his brother has more patience than this. His brother has more endurance than this. He will suspend where he is until Sasuke says otherwise.
And Sasuke does intend to take his time, to appreciate the sight of his brother lying underneath him in ache, to taste his torment with every passing pulse.
He forces Itachi's mouth wider as he slips in his tongue inside. The contact brings out another tremor. Sensing his brother is going to overflood, he lifts Itachi's head off the pillow.
As he brings them up, his hands travel down Itachi's waist before he pushes him down into a sit. The vibrator pushes in deeper, at just in the right angle to send Itachi over the edge.
Their kiss breaks in a gasp of air.
Itachi digs his fingers into Sasuke's shirt, forehead pressed against his shoulder. Sasuke lets himself be used as crutch.
But while Itachi unwinds, Sasuke is increasingly excited. With all of his brother's heat and pheromones in the air, Sasuke is dying to free his own erection out of his pants.
He waits until Itachi's breath evens. "Nii-san?"
Rested against him, Itachi gives a hum to show he is listening.
Sasuke hesitates. He wonders how generous his brother is feeling today. Itachi tends to comply with his demands, but there is an off chance that Sasuke will epically piss him off. The last time he tried surprise snake sex, Susano'o slammed his ass through three walls and a laundromat.
"Just say it." Itachi tilts his head and plants another kiss. He smiles. "I'll amuse you today."
