Crack. You have been warned. Also implied threesome and multiple partners. Drabble-ish.
Watanuki could feel Yuuko's breasts pressing against his back--inevitable, since one of her arms was wound around his shoulders. Her other hand was playing with his ear. For all that, though, his brain was still stumbling over the fact that it was *Doumeki's arms around his waist, and *Doumeki's* teeth nibbling at his other ear. His mind was frozen, he had no idea where to put his hands, and in the background Maru and Moro were chanting something.
"Uh," he said. "Um. Y-Yuuko-san?"
"Yes?" she breathed into his ear, slinky and sly.
"Um," he said again. "What--what are--"
"What are Doumeki-kun and I doing?" She was radiating heat and amusement, and he knew she had that shark's grin on her face, even if he couldn't see it.
"Er. Yes. That."
"Well," her finger dipped to slide along his jawline. Maru and Moro were still chanting. "We were thinking--Doumeki-kun and I--that we'd like to work out an arrangement.
"O-oh?" Damnit, couldn't Doumeki quit nibbling for *five minutes* so that Watanuki could think?
"Yes. I want you Sundays, Mondays and Tuesdays, and Doumeki-kun gets you Wednesdays, Thursdays and Fridays."
"Ah?" Watanuki thought he should be violently opposed to this--for, for, some reason--but Yuuko was very warm against his back and Doumeki (that jerk) was sucking on his earlobe, and he just couldn't *think.*
"Ah," he said. "Ah, Yuuko-san--"
"Yes?"
"Today is Saturday."
Doumeki spoke for the first time, his breath warm against Watanuki's ear. "Saturdays we share," he said.
Watanuki could finally make out what Maru and Moro were chanting: "Watanuki's in a threesome!
"Threesome!"
He wondered what he'd done in a former life to get *this* kind of karma.
...I did say it was crack, yes?
