The idea being Tobio's seemed to have no bearing on his anger, and, trying to muffle his laughter, Shōyō tugged on the knot which bound his hands to the bed post whilst mourning the possibility that after this, Tobio may have an aversion to any experimental sexual exploits. Rather a disappointment; he had just gotten comfortable enough to discuss these things with Shōyō.
"Stop laughing, Shōyō," Tobio said. "This is all your fault." He struggled against his bonds and winced as he felt new bruises forming. Shōyō ran his fingers along his wrist, his lips pressing together when he saw the reddened skin until Tobio elbowed him in the chest.
"It was your idea!" Shōyō exclaimed, his nose wrinkling the way it did when he was hurt and angry.
"I thought you could tie a knot that you could actually undo!"
Wow, he really was furious. Sparks flew from his eyes and Shōyō almost fell off the bed backwards when he scrambled away from the murderous expression, considering an escape route.
"Don't you dare, Shōyō. Undo the knot now."
"I'm trying." He tugged at the knot again, giving an exclamation of pain when one of his nails bent backwards. Tobio continued glaring as he sucked his finger and struggled again. "You'll only make it tighter if you keep on pulling like that."
"We are never doing that again."
"Really?" Shōyō said around his finger as he studied the knot from all angles. "You talked me into it in the first place, Tobio."
"Well it was one of fantasies, but I didn't—" He broke off and his cheeks darkened. "I didn't think it would end up like this. I trusted your ability to tie a simple knot."
He really did look morose at that (though still trying to hold the illusion that he was merely angry), resembling a child who had just found out Santa didn't exist.
(An incongruous image with the fact that he was currently tied up and naked, but Shōyō tried to ignore that fact. He was pretty sure that the last thing Tobio wanted was a second round when he was still like this.)
When the façade dropped away completely and he simply looked as if all his dreams had been crushed, Shōyō definitely felt guilty that he hadn't taken more time and more care beforehand and hadn't stopped his hands shaking as he had hurriedly tied the rope. His lower lip trembled and he sniffed before leaning his forehead on Tobio's shoulder, squeezing his eyes shut to try to stop the tears. "I'm sorry," he said, his voice quivering. "I'm so sorry, Tobio." He tightened his arms around Tobio's chest, a few tears leaking out when he realised Tobio couldn't do the same and it was entirely his fault.
"D-dumbass," Tobio stuttered, blushing again when Shōyō looked up at him with tears in his eyes. "It's not your fault," he admitted. "I kinda… uh… sprung it on you. I should have given you more time to prepare." His voice was gruff and Shōyō tightened his arms again, pressing a kiss to his collarbone.
"Worst comes to worst I'll just keep you here as my sex slave," Shōyō joked, his eyes creasing at the corners as he smiled widely. With his cheek against his chest, he felt Tobio's heart rate pick up and his breathing hitch and slowly pulled away to look at him narrowly. "Really? Don't tell me that's another one of your fantasies," he said, crossing his arms. Tobio darted a sheepish look at him before resolutely looking out of the open window. "Are you a masochist?" he asked curiously, scrambling backwards on his knees when Tobio gave him another murderous look. "It was just a question. I really think I should know these things."
"Whatever. Are you going to get me free or not?"
Shōyō, a determined look Tobio recognised from games on his face, nodded and muttered 'Fight!' under his breath before working anew at the knot. "I have an idea," he said when it still wasn't any looser a minute later. "Wait here a minute," he said, wrapping a blanket around his shoulders (as Tobio sarcastically said, "Oh, of course I can move.") and going to the kitchen to take a knife from the utensil drawer. Tobio's face was a sight to be seen when he came back, the blood draining from it and an expression filled with horror. "Relax; I'm not going to use it on you. Keep your hands still." He sawed at the knot, crying out in triumph when Tobio could tug his hands away and slip the rope off his wrists. Chucking the knife somewhere behind him, he bounded into Tobio's arms, kissing his lips lightly before saying, "Want to try that again?"
At which he was dumped to the floor, Tobio's expression indignant and still slightly horrified.
