Tim finished fastening the buckle and leaned back. “How does that feel?”
Kon gingerly raised his hands to the collar, feeling around the thick leather and metal and, in the center, the hard edges of the red sun projector. A gentle red glow washed over his hands, and he watched the play of it on his knuckles, heart racing with an uneasy mix of fear and a sort of odd, shivery anticipation. Already he felt his powers fading, his senses narrowing and narrowing until they strained even to exceed the limits of Tim’s bedroom. It was a strange and not entirely pleasant feeling, like his ears were stuffed with cotton, like the cold sterile rooms at- he forced himself to cut off that train of thought, and looked up. Tim was looking at him, mouth pressed in a thin line.
“This wasn’t a good idea,” Tim said. “Let’s just-“
“No, no,” Kon said hastily. “We talked about this, we agreed. It’s just- I just need to take a bit to get used to it.” And he was getting used to it; with his mind focused firmly on the present and his senses attenuated to nothing but his immediate surroundings, Tim’s warm presence in his lap and the way he was shifting his weight took on a new significance. Kon settled his hands on Tim’s hips and stroked them a bit. Tim’s hands fluttered over his chest, the collar, like he wasn’t sure of his welcome.
“If you’re sure-“
“I’m sure,” Kon said firmly. He nestled back a bit further into the pillows and took a deep breath, forcing his body to relax. Focus on Tim, he reminded himself. He ran his palms up and down Tim’s sides, feeling the gorgeous lean musculature of him, the heat of his body, even if Kon couldn’t hear his heartbeat. He smoothed his hands down Tim’s thighs, and Tim seemed to relax a bit as well, settling his palms on Kon’s chest. Kon dared make eye contact again; Tim’s eyes were creased with a fondness that had Kon’s throat suddenly locking up.
“Hey, beautiful,” Kon said. It came out a little hoarse.
“Hey yourself,” Tim said. He leaned down, and Kon gave a pleased hum. Kissing Tim was one of those things that just never got old. He slid his mouth open, deepening the kiss, lost in the sensation of Tim’s mouth on his. And when Tim gave him a teasing nip- he gave a shocked little noise, the unexpected bright spark of pain arcing straight to his cock. Yeah, that definitely felt good. He pushed his hips up, sliding his thickening cock against Tim’s, reveling in the slide of skin on skin.
Tim pulled back a little, Kon chasing after his mouth. They were both a little breathless. “Eager, are we?” Tim asked, smiling a little knowingly, more affectionate than mocking, and Kon couldn’t find it in him to be embarrassed. Tim’s hands were roaming confidently now, sliding over Kon’s nipples; the collar turning the kind of firm pressure that Kon usually liked into something deliciously intense - Kon moaned, and pushed his chest into the feeling, chasing more of it.
“Yes, please.” He was panting now, fully focused on Tim, Tim’s hands, his wet kisses. His earlier anxiety felt far away- this was Tim, wonderful, beautiful Tim, and Tim would never do anything to hurt him. “Please-”
“Be patient,” Tim said. “You’re doing so well. Just stay still for me, baby-”
Kon gave a noise of complaint as Tim’s weight left him, and then his wrists were being gently pressed up and together. There was a faint clinking noise, and then when Kon tried to pull his wrists free, he found that he couldn’t. He was completely at Tim’s mercy, and the thought of it made him moan and arch, body twisting against the sheets, pulling at the restraints, his cock pulsing a little at the tight press of them against his wrists. There was more movement, then more deliciously novel sensation as Tim slid the ropes around his torso and legs, tying them snugly. Kon squirmed again at the friction of the rope on his nipples, on the sensitive skin of his inner thighs, his ass. With no extraneous senses to distract him, and a body made vulnerable by the collar, everything seemed dialed up to eleven, hot and overwhelming and raw. His cock strained against nothing, exposed and helpless.
“Tim,” he panted. He arched up again, hoping for friction; the movement caused the ropes to constrict even more - so tight - he moaned again, a wordless plea. He needed- he needed-
“Ssh, I got you.” Tim’s voice was rough. There were wet noises, and Kon opened his eyes; he groaned at the sight of Tim taking the plug out and setting it aside, sliding lubed fingers into himself to test the stretch. Tim’s eyes slid shut, and his mouth fell open a little, working himself back on his own fingers. His whole face was flushed, down to his chest. Kon wanted to kiss that beautiful mouth, he wanted those to be his fingers, his tongue, his cock sliding into Tim, he- he wanted Tim to use him, to take what he wanted from Kon, to use Kon’s body to make himself come.
“Almost there, baby,” Tim said breathlessly. “You’re doing so well for me, being so patient.” Kon made a plaintive noise, flexing against his restraints. Tim’s pretty cock was hard and flushed and wet against his own thigh, and his hand behind himself was moving a little faster. Kon wanted him so badly. Tim opened his eyes, gaze meeting Kon’s and then moving slowly downwards, taking in the sight of him, and Kon watched as Tim’s cock twitched a little, a bead of precome sliding down the head. “God,” Tim breathed. “God, you look so good. Do you- fuck,” he pulled his fingers out, shiny with lube, and reached for the bottle, squirting out some more and sliding it deliciously over Kon’s cock, coating it. Kon made an aborted moan at the sensation, and Tim surged up to kiss him again, hungry and devouring. Kon matched him eagerly, straining up against the hold on his wrists to try and get as much of Tim as he could. Tim’s slick hands were sliding all over his body, feeling the way the ropes pressed into his skin, squeezing his ass, the muscle of his waist, dragging up again to pinch and tug at his nipples. Kon made a sharp noise into Tim’s mouth, cock jerking, writhing underneath Tim, but Tim’s thighs squeezed down around his waist and he would not be budged. Kon could feel his cock pressed up against the cleft of Tim’s ass, smearing precome, and he moaned again.
“Please,” he begged, “please, Tim, let me fuck you, let me-”
“Yes, fuck,” Tim moaned, and then he wasn’t saying anything, because he was sliding down on Kon’s cock, hot and slick and tight, and Kon squeezed his eyes shut and tried not to come. Tim paused for a moment at the base, panting and trembling, sweat dripping down his flushed face. His hands flexed where they were planted on Kon’s chest for leverage. Kon dared open his eyes a bit, and the sight of Tim above him, around him, his beautiful body straining to accommodate him, made his cock jerk again, helplessly. Tim’s face twitched a little.
“Oh fuck,” he said. “Oh fuck that’s full.” He shifted his hips a little, trying to get a more comfortable angle. Kon bit his lip at the sensation, hands digging into his restraints uselessly, unable to touch. Tim began a gentle rocking motion, back and forth, brow furrowed in concentration, then faster and faster, his hands digging into the ropes crossing Kon’s chest. Kon squirmed, caught between the torturous drag of the ropes and the hot clench of Tim’s body. It was too much- he had to-
“Please,” he begged again, “please can I- ” he swallowed, strained against the hold on his wrists again.
“Yes,” Tim panted, “yes, whatever you- fuck!” as Kon snapped his hips up, fucking into him at a brutal pace. “Oh fuck oh fuck. Oh fuck right there yes- Kon-” and Kon knew it was the right angle, even without his powers, even as his muscles started to burn with bright, unfamiliar exertion. “Oh fuck that feels so good,” Tim moaned. He braced himself on Kon’s chest, pushing his ass back to meet Kon’s slapping thrusts, and the tight hot vicious spiral of pleasure was pulling Kon inexorably under- but he couldn’t- not yet- Tim- he thrust faster, harder. Tim was making little desperate noises, his body one long tight straining arch against him. “Kon you- I can’t- oh fuck-” and then he was squeezing down like a vice and coming messily all over Kon’s stomach, crying out, and that was it, Kon was shouting and coming deep into Tim’s body in long clenches, pleasure locking up his whole body, two pulses, three, then four. He could feel his come dripping out of Tim’s hole, pooling wetly where they were still joined, and his cock gave another weak spurt at the sensation.
Tim collapsed weakly over Kon’s chest, panting, his face pressed into Kon’s neck. After a long, sweaty moment, one hand fumbled up to turn the red light off on his collar, then groped around the nightstand for the remote that would open the shades to allow sunlight to filter in, its warm yellow glow spreading comfortingly throughout Kon’s body. The friction of the ropes on his body faded to a faint, almost unnoticeable pressure; the soreness where the restraints had chafed on his wrists a little melted away. Kon watched hazily as Tim pushed himself upright, a little unsteadily, and unbuckled the collar from around Kon’s neck, sliding it off to put on the nightstand. Every part of Kon’s body felt fantastic, supremely relaxed. He never wanted to leave Tim, the warm clutch of his body, this golden sunlit room. Almost dreamily, he snapped his wrists free of the restraints, bringing his hands up to gather Tim to his chest, his softening cock slipping free with a gentle rush of come. He held Tim like that, tightly, and Tim’s arms slid around him and held him right back, and they drifted like that for a while, just enjoying the feeling of closeness.
“We’re a mess,” Tim mumbled after an endless moment. “I think I’m gonna have to cut these ropes off of you. And then maybe burn them.” Kon snorted into Tim’s hair, but loosened his grip, and Tim struggled upright, his hair disheveled. The warm sunlight rimmed his face and body with gold, and the beat of his heart was steady. Outside, Kon could hear Alfred pruning the bushes in the gardens, and even further than that, the ever-present sounds of people going about their business in the world. Tim was just looking at him, unbearably fond, all the sharpness of Robin fallen away, and Kon knew his own face had to be doing something similar. Tim’s hand was on his side, his thumb stroking over one of the ropes where it crossed over Kon’s torso. Kon reached over and gently covered Tim’s hand with his own.
“We’re doing that again, right?” he asked.
“Oh yes,” Tim said, smiling a little. “We definitely are.”
