Yoruichi was unlike nearly every other woman Sasuke had ever met. She wasn't clingy -in fact it was her that demanded space- nor was she weak. She was as strong physically as she was mentally, knowing when to be flirtatious, and when to focus, when to be serious.
She would come and go as she pleased without so much as a whisper of warning. She would be gone for days, weeks, sometimes even months before visiting again. Nothing. Sasuke would return to his lodgings for the night, and there she would be, a black cat, curled in a ball of fluff, golden eyes glowing up at him. He would sit down, and Yoruichi would pad over to him, affectionately nuzzling the hand the had reached out and pet her. She'd crawl in his lap, paws rested against his chest, nuzzling under his chin before she'd transform, leaving a rather exotic woman with a cascade of purple tresses falling down her back into his lap.
"You're naked, Yoruichi," he would state, and she'd give him a feline grin.
"That's never bothered you before, Sasuke," she purred.
Where the had once been nuzzling under his chin there was now small, soft nips, kisses, and a soft tongue darting over where his pulse met the surface. Eventually he would sigh, pale hands running up over dark skin into the violet locks as she placed a small, soft lick to his cheek -something that almost made him want to laugh, how somethings just didn't disappear between her two forms- and finally found his mouth with her own.
Their tongues dances, a fight for dominance, not that it really needed to be done, they both knew Yoruichi was in charge, but he was an Uchiha, and his pride wouldn't let him submit completely. Still it was her that set the pace, how they move, touched. It was her that had showed him how, teaching him, letting him spend hours pouring over her body, showing him where to touch, how hard, how soft, and at what time. She molded him into quite the perfect little lover, and thought she didn't admit it, she became addicted, and kept coming back for more.
They would kiss, until she broke free from it, tilting her head back, her hair tickling the inside of his thighs. Sasuke would bury himself in her neck, licking, sucking, biting. She would whimper, which would melt away to moans as his hands -callused from the rough handling of kunai and shuriken on a daily basis- traveled up her side, a stray thumb rolling a nipple in small circles. Her hands busied themselves with pushing away his shirt, fingers dancing over the pale flesh, over the tiny sensitive spot on his neck where the cursed seal once was.
Untangling herself from Sasuke, she'd push him onto his back, running her fingers down his chest, down to the waistband of him pants, pulling them down over his hips, down and off his legs. Yoruichi would tease, fingers scratching lightly over his thighs, lips pressed so undeniably close to his erection, a tongue running up from base to tip until Sasuke just couldn't take much more. He'd sit up and grab her, tossing her back on the bed. She would grin up at him because they both knew she allowed him to do so, and that she could toss him across the room like she had done when they sparred like he weighed nothing.
The next few hours seemed to blur for both of them. Pale skin sliding against dark skin, yells, moans, fingers pressing hard into flesh, teeth scraping over skin, lips pressed against the other's, backs arching.
Afterward they would back in the afterglow, chests heaving, hearts pounding like they were trying to escape, Yoruichi curled at his side purring contently until they both fell asleep.
In the morning Sasuke would wake alone, the only reminder that Yoruichi had even been there was her scent, and the blankets that had been pulled up neatly over him to accommodate for her missing warmth. She would be back, this he knew, it was never being able to tell when.
