Hikaru lounges on the bed with a candy cane dangling loosely between his lips as he watches Kaoru across their room, bent over their desk doing homework. He insisted on doing the majority of what they were assigned over Christmas break; Hikaru didn't really see why - it seemed easier to just do a little bit every day.
"Are you done yet?" he finally drawls out around the candy in his mouth when he can take no more of being ignored for math equations.
"Nope, still got plenty to do," answers his twin without so much as lifting his eyes from the papers he's hunched over.
"I'm not saying delay it forever, but can't you do the rest of it tomorrow?"
"Why not just finish it now while I've got plenty of time for it?"
Hikaru huffs at the response. He doesn't much like being ignored, especially not for homework. He drops the candy cane on the bedside table and saunters across the room to his twin, draping his arms around Kaoru's shoulders. "You've got plenty of time to finish it later, too, you know." he murmurs before pressing sticky kisses against the younger twin's neck. "Besides, you'll get yourself all worked up if you try to do it all now. So let me help you destress a bit." he practically purrs.
And that is how Kaoru finds himself face down on the bed, his chest heaving against the sheets, and his ass pressed high in the air as Hikaru slowly moves the candy cane in his puckered hole.
Hikaru beams with satisfaction at the little noises of pleasure his brother lets out, but he knows this is hardly enough stimulation to get him over the edge. He leans down to swipe his tongue around Kaoru's rim, earning himself a soft gasp of, "Hikaru!"
He smacks his lips together and grins. "You taste all pepperminty now."
"Hikaru!" whines Kaoru, glancing over his shoulder. "Don't tease me."
It's that pout. Hikaru can't deny that pout a thing. So he takes the candy out and replaces it with his tongue, tasting sweetness overlying the earthy taste of his brother. Kaoru moans with every movement of the muscle, crooning his brother's name as Hikaru presses sloppy kisses and broad tongue strokes across his hole.
And when Kaoru comes his back arches and his toes curl and his moans get caught in his throat as pleasure crashes through him, dirtying the sheets below. He shudders and whines as the orgasm washes over him until he collapses spent against the pillows, huffing in deep breaths.
Hikaru pulls his twin into his arms and kisses his head, only for Kaoru to pull back with a devious smirk. "Please, brother dearest, allow me to return the favour." he hums as he unbuttons Hikaru's fly.
Collectively they come nearly eight times before the sunrises.
