Steve rode Thor hard and fast and enthusiastically, sweat-dampened hair falling over his brow, head thrown back, eyes closed, mouth open, a never-ending stream of "Yes" and "Please" and "Oh, fuck" falling from his lips. Close...he was so, so close. Thor rubbed his trembling thighs and smiled up at him. "Not yet, love. Slow down."
But Steve only picked up the pace. "I can't help it. It feels so good." He fisted his erection and stroked himself in time with Thor's cock driving into him.
Thor grabbed his wrist. "Wait!" But it was too late; Steve came with a shout, striping Thor's stomach. He leaned back on his hands between Thor's knees, lifting his hips. Thor thrust up into him three, four, five more times before coming himself. They were still for a moment, panting, coming down from their orgasms, then Thor placed a hand on the back of Steve's neck and pulled him down into a kiss. "You need to be more disciplined, my pet."
Steve huffed a laugh at the endearment. "Then teach me, my Lord."
Thor smiled indulgently and kissed his temple. "I shall."
The next evening, Steve received a text summoning him to Thor's room. When he arrived, Thor was standing against the far wall, arms behind his back, wearing nothing but a pair of obscenely tight jeans. Steve smiled and took a moment to admire his physique before walking toward him. "So, what do-"
"Stop."
Steve halted about halfway across the room, looking at Thor uncertainly. He pushed off the wall and stalked slowly towards Steve. He wasn't smiling. Now that Steve could see his hands, he saw Thor was holding a riding crop in one and what looked like a small strip of leather in the other.
"On your knees, pet. Now."
Steve raised his eyebrows, but rushed to comply. Thor moved to stand in front of him, mere inches away. Up close, Steve could see that the strip of leather was actually a dog collar. He thought he could see Thor's game, and he wanted to please his lover. He ran his hands up Thor's legs and pressed a kiss to his inner thigh, but before he could do any more, Thor brought the riding crop down across his shoulders, just hard enough to sting a little.
"I did not give you permission to touch me."
Steve looked up at him. "I just wanted to-"
Thor gave him another light smack. "I did not give you permission to speak, either." Thor fastened the collar around Steve's neck. "When you wear this, you belong to me. You do exactly what I tell you, nothing more, nothing less. You say nothing other than 'yes, my Lord' in response to my orders, unless I ask you a direct question." He looked down at Steve hesitantly. "Do you agree?"
Steve smiled brightly. He was suddenly more aroused than he'd ever been in his life. "Yes, my Lord."
Thor looked relieved for a brief moment before shutting his face down and looking stern again. "Good." He sat on the bed. "Strip."
Steve stood and practically ripped his t-shirt off in his haste to obey. He kicked off his shoes and socks as he struggled with his belt, and finally managed to get his trousers and boxers off. Thor gestured to the space between his knees. "Come here." Steve stepped in close enough to rub his erection against Thor's stomach, hissing at the friction. Thor laid the riding crop across his lap and placed his hands on Steve hips, pressing him back a bit, with his thumbs teasingly close to the base of his cock. "You are too eager. You always go as fast and hard as you can. You do not take time to touch," he rubbed his thumbs in the coarse blond hair beneath them, "to taste," he licked the drop of precum from the tip of Steve's cock, eliciting a groan; Thor picked up the riding crop again, "to savor the sensations..." he trailed kisses across Steve's hip and up his side, careful to scratch his beard in the dip of Steve's hipbone where he knew he was sensitive.
Steve shivered. "I know, I'm sorry, but it feels so good I can't help-"
Thor delivered another blow with the riding crop, harder than before, across the back of Steve's thighs. "I did not ask for a response." He stood, pressing one leg between Steve's as he wrapped his arms around his waist. He nuzzled Steve's neck for a moment then kissed him softly. Steve moaned against his lips and tried to deepen the kiss, but Thor wouldn't allow it, he kept it soft and chaste. Thor could feel the tension and frustration in Steve's body. Steve tentatively laid one hand on Thor's bicep, and when he wasn't rebuffed, squeezed his ass with the other. When he still was not corrected, he became bolder, rutting against Thor's thigh and breaking their kiss to lick a stripe down his throat and nibble at his neck. Thor allowed it for a moment, then brought the crop down again across Steve's backside, this time hard enough to make him cry out.
"You are not learning. I want you to be patient." He pushed Steve back into the center of the room. "Back on your knees. Be still and quiet."
"Yes, my Lord."
Steve did as he was told. Thor knelt behind him and wrapped him in his arms. He nibbled at Steve's neck, up to his ear, and down along his jaw to place a kiss at the corner of his mouth. Steve did his best to stay quiet, though he couldn't resist turning in to the kiss. Then Thor took Steve's cock in hand, with just the bare lightest of touches, and began stroking him. It wasn't very long before Steve was bucking into his hand, begging for more pressure. Thor removed his hand and sat back. He ran a finger along the back of the collar. "Should I take this off, pet? Do you want to stop?"
Steve could hear the disappointment in his voice. "No! Please, don't stop. I'll be good, I promise."
Thor stood up. "Will you?" He began pacing the room. Steve concentrated on being still, but he couldn't help the occasional whimper escaping, or looking up when Thor passed close by, hands twitching to reach out and touch him, or licking his lips when he caught sight of the bulge in the front of Thor's jeans. After a couple of minutes of this, Thor sighed and leaned against the door frame of the ensuite bathroom. "I've been counting the seconds in my head to the moment when we could continue, but with every noise or movement, I have to start the count over again." Thor began palming himself while he looked down at Steve. Much as he wanted to, Steve couldn't watch. He knew it would lead to more disobedience.
Thor began making little moans and sighs and other delicious little noises, but Steve didn't dare look up, and if his cock twitched with interest, well, he hoped Thor wouldn't hold that against him, since it was completely involuntary. After what felt like an agonizingly long time, Thor said proudly, "Very good, pet." Steve looked up, hopeful. Thor was smiling broadly. "It seems you can learn." Steve licked his lips as he leaned forward, eager to get closer to Thor. "You may touch me now."
Steve couldn't get there fast enough. He didn't even get his feet under him, just scrambled across on all fours. He smiled up at Thor. "Thank you, my Lord." Thor smiled even more broadly, and stroked his hair. Steve practically purred in response, then opened his jeans and pulled them down just enough to free his cock. He swallowed him down immediately with indecent enthusiasm, bringing a hand up to stroke what he couldn't fit in his mouth. Steve heard Thor's head thump against the wall behind him, and Thor placed hand on his head, guiding him, but not forcibly. Not that Steve would have minded. He would happily gag on Thor's cock for the rest of the night if he could. Though he did look forward to what would follow, when Thor would pull his head back gently, bend down to kiss him, and pull him to his feet and push him back to the bed...
Steve took himself in his other hand, moaning around Thor's cock. He hoped Thor wouldn't notice what he was doing, since he didn't think he'd be too happy about it, but he was painfully hard and needed release. He glanced up, and was relieved to see that Thor still leaned back against the wall, his eyes closed. Steve continued sucking, licking, swirling his tongue around the head, hand tightly gripping the base, or massaging his balls, all the things he knew Thor liked. He stroked himself hard and fast, losing himself in all the sensations. He was so, so close...
Suddenly, Thor tightened his fingers in Steve's hair, pulling him off his cock and throwing him roughly back. Steve lost his balance and landed hard on the floor. Thor was on him before he could recover, straddling his waist. "Did I give you permission to touch yourself?"
"No, my Lord."
Thor ran his thumb across Steve's lower lip, then along the collar. "Did you think I would not notice?" His voice was soft but dangerous. Steve didn't answer; he wasn't sure what he should say. Thor slapped his cheek, just hard enough to be a warning. "I asked you a question, pet. Did. You think. I would not. Notice."
Steve swallowed hard. "I hoped you wouldn't."
Thor just stared at him for a few moments, then stood and walked into the bathroom. "I want you gone by the time I come out," he said, without looking back.
Steve sat up quickly. "No, Thor, please! I'm sorry, don't-" But he was cut off by the door slamming shut. He considered staying, begging Thor to reconsider, but in the end, he decided that was a bad idea. Thor wants him to be patient and obedient; the least he could do is follow his last order. "Yes, my Lord." He gathered his clothes quickly and fled across the hall to his room.
He left the collar on.
