Saiunkoku Monogatari, Seiran/Ryuuki, "there are no limits to my devotion to you" 1/2 Note: Follows immediately from Seiran/Shuurei, first kiss, above
“…we’ve interrupted something.” Ryuuki had just stopped, half in and half out the door to Shuurei’s chambers in the imperial harem. “We didn’t know… Shuurei and Seiran were like that? So. We see.” He looked…broken, looking between the two of them like he didn’t know what to do. “We should go.”
The words tore out of his throat on their own, “Heika! Ryuuki—wait.” The crimson of Shuurei’s sleeve flashed in the corner of his eye as she reached for the retreating figure in the door; he was already past her though, just fast enough to catch Ryuuki’s hand as he tried to slip back into the darkness. “Don’t go.”
“Aniue…” Ryuuki’s eyes fixed on his, pain-wide and confused, before Shuurei padded up next to them.
“Come in,” she pressed, quiet. “It’s too cold out there for just your nightrobe.” Her small rough hand slipped into the one Seiran wasn’t holding. “How many times do I have to tell you?” Seiran stroked down the Emperor’s back, gentling him like a skittish mare, as Shuurei led them far enough into her rooms to let the door fall shut behind them. “It’s not…like you think.”
Ryuuki was still looking back and forth between them; slowly, he drew his face into a feeble attempt at a theatrical pout. “Ne…Shuurei’s giving kisses? No fair—Seiran got a kiss. I want one too,” he said, half-joking, like he expected to be thrown out any minute alone into the night. Seiran held his breath, eyes locked on his lady as he pressed his chest to Ryuuki’s back and blocked his exit.
Shuurei looked almost as afraid as Ryuuki; Seiran saw the expression and let himself relax—Ojou-sama never let fear stop her from doing what she thought was right. And sure enough, a moment later she closed her eyes and nodded. “Un. That sounds fair.” She had to go on tip-toe to brush her lips against Ryuuki’s; when she would have pulls away, the emperor fastened his arms around her waist, fit her into the curve of his body so he could take her mouth properly, hungrily. The muscles in his shoulders shifted against Seiran’s chest as he balanced her weight against them; Seiran choked back a low noise of want as he watched Shuurei melt into his brother’s kiss.
“Enough,” she whispered when Ryuuki finally let her go. She tucked a stray lock of hair back away from her face. Ryuuki’s harsh breathing was loud in the silence around them, pressing rhythmically against Seiran’s body. “Seiran—”
“Un. I remember, Ojou-sama. I won’t run away.” He smiled at her, proud and open, until she nodded, stepped back to sit again, a little shaky, at her dressing table. Ryuuki turned in his arms, eyes hesitant with a question he didn’t voice. “I already told you, didn’t I?” he asked casually, threading his fingers through Ryuuki’s pale hair. “Despite the resemblance, I’m Imperial Guard Seiran, not Seien.” Ryuuki’s eyes went wide with understanding as Seiran bent his head to steal a kiss of his own. Ryuuki’s thin fingers fisted in Seiran’s jacket, white knuckled. “You’re my sworn Emperor; there will be no limits to my devotion to you.” Ryuuki moaned softly against his lips.
“Sei…ran.” The dart of Ryuuki’s tongue against his lips made Seiran gasp; he felt himself harden, pressed closer against the man in his arms. Over Ryuuki’s shoulder, Shuurei was watching them with a fragile, determined look. She met his eyes and nodded once, and he smiled at her as he tumbled Ryuuki into her bed. The panicked look Ryuuki shot at her as he arched up between Seiran’s solid body and the soft give of the mattress made them both laugh.
