Summary: Aaron think's he had an idea what Spencer likes. He's wrong.
Prompt: Hotch is thinking about asking Reid to sleep with him after they have been 'dating' for about two months. He knows from past conversations after cases that Reid is not vanilla, but he has always assumed Reid would be a sub/bottom... But is he?
A/N: Another little warning, I started this when I was feeling fine, wrote the middle while trying to trudge through writers block and wrote the rest while hopped up on caffeine and listening to Rihanna's 'S&M'. I think this should count as a warning :P

Aaron Hotchner was not a man who talked about sex when it came to his personal life, it was something he just didn't discuss.

He'd married his childhood sweetheart, they'd waited until their wedding night and the whole thing had been implied in the tradition and therefore had required no ... planning. But now, he was with someone else and there where no traditions to fall back on, no set rules, he was completely lost. He knew Spencer was avoiding mentioning it because he was more experienced than Aaron, especially when it came to being with another man, and he didn't want to rush him.

The one thing Aaron knew about Spencer was that his past experiences where somewhat less than vanilla, especially compared to Aaron's 'Missionary Only' marriage. His lover hadn't gone into detail or anything and he hadn't actually mentioned sex again at all, giving Aaron the space and time to bring it up on his own.

The only problem was, Aaron didn't have the slightest idea how to broach the subject.

He downed his fourth glass of wine and smiled sheepishly at Spencer who was studying him curiously.

"Is something wrong Aaron?" He asked.

"No, no." Aaron chirped brightly, too brightly, while pouring himself a fifth glass of wine then offering Spencer a refill. His lover refused, still nursing his first drink, and raised an eyebrow letting Aaron know he wasn't buying it.

Lowering his head to hide his blush, Aaron finally decided that if he wanted Spencer, and good lord did he want Spencer, he would just have to take the plunge, "I wanted to talk to you about ..." 'Oh god, I can't', "Us."

Spencer placed down his glass and folded his hands before him on the table. He fixed Aaron with a serious but warm expression and asked, "Us?"

Aaron immediately realized how that must have sounded and rushed to correct his mistake, "I'm happy with us, thrilled actually. I just mean that." He cleared his throat, " We've been together for just over 2 months now and .. " Aaron closed his eyes. He was so bad at this.

"Aaron," Spencer asked, holding back a smile, "Is this about sex?"

He laughed and let his head drop into his hands, typical of Spencer to just come out and say it. Unable to trust himself not to giggle, he simply nodded.

Spencer chuckled before reaching out and gently pulling Aaron's hands away from his face, "We can talk about it you know. I think we should. We need to establish your boundaries."

Raising his eyebrows, Aaron asked, "My boundaries?" 'What kind of sex is he talking about?'

Still smiling, Spencer said, "Aaron, don't worry. I just mean because you've never been with a man before. The extra-curricular stuff can wait till later." Taking a sip of his wine, Spencer murmured, "Much later."

Aaron frowned. He couldn't explain why, but he was kind of offended! "You don't think I could handle it?"

Now it was Spencer's turn to frown, "Of course not, you know I don't think that way. I just like some things that can be rather ... intimidating at first. That's all."

'Oh, that's all.' Though he knew it was irrational, Aaron couldn't help but see that as a challenge, "Spencer, I face serial killers for a living. I think I can handle a little," 'Wait a second', "What exactly are you into?"

His lover shifted in his seat, straightening as though preparing for a long conversation, "Nothing too extreme," He sad, waving a hand dismissively, "Just restraints you know, blindfold, gag, the whole thing. Maybe a little spanking." The smile when he said 'spanking' was almost enough to make Aaron smile back. Almost.

"I can handle that." Aaron said with certainty. It wasn't exactly something that he would want or ask for, but he could handle having sex with Spencer while he was cuffed to the bed. The idea of his beautiful lover spread on the bed, restrained, didn't appeal to Aaron as much as he felt it should but still, he could do this. He was Aaron goddamn Hotchner, Unit Chief.

"You know you don't have to prove anything to me. I mean I've always thought based on your personality and other factors that you might be receptive to this particular 'form' of sexual activity but there's no reason to rush in."

'What! 'based on your personality and other factors'? What the hell was that supposed to mean? Am I really that controlling. I'm only that way because I have to be, it's not like I enjoy it.'

Refusing to back down, he repeated, "I can handle it."

Spencer rolled his eyes slightly, "Aaron you can't even talk about TAME sex without half a bottle of wine in your system, and there's nothing wrong with that. You're old fashioned, it's kind of charming."

'Okay, now he's being intentionally condescending.'

Not saying another word, Aaron took hold of Reid's wrist, pulled him out of his seat and pulled him close, kissing him.

It was deeper than any other kiss they'd shared to date and Aaron could feel himself hardening.

When they pulled apart Spencer was breathless and looking at him with hunger in his eyes, "Okay. Restraints only." The door bell rang, it was Haley with Jack "Tomorrow night." Spencer whispered before heading into the study and sitting at the computer.

Heading towards the front door, Aaron felt simultaneously victorious and terrified.

~~~~~~~*~~~~~~~

Aaron was sat on the edge of the bed wearing only his boxers and trying not to freak out. The more and more he thought about this the more unsure he became. He had always seen Spencer's strength but not in a way that made him want to suppress it. Quite the contrary, he wanted their relationship to make Spencer confident enough for it to grow. Spencer's willfulness and his sense of self had always been incredibly attractive to Aaron and the idea of rendering him immobile, helpless, was not only un-appealing, it was a full blown turn-off

He was drawn from his thoughts by Spencer, wearing nothing but his beige khaki's and a thin, white shirt unbuttoned down to mid chest. His long hair was shaggy and messed up. It was probably the sexiest image he'd ever seen. Just as the iron grip of fear was about to release it's death hold on his chest, Spencer pulled his handcuffs from behind his back and hooked a finger in each wrist piece.

"You sure this is what you want." He asked seriously, soothingly. Aaron had no doubt that if he backed down now, it would be met with nothing but understanding.

'If I can't do this, if I can't give him what he wants, I have no place being with him.'

"I'm sure." He whispered, lying.

"You know, we can stop any time you'd like." Spencer said, twirling the terrifying restrains around his fingers.

"Safe word." Aaron remembered.

Spencer nodded, "Got one in mind?"

'Wait,' Aaron thought, 'He wants me to pick his safe word? Is this a control thing?'

Deciding that it must be, Aaron blurted the first random word that sprung to mind, "Spider." The fact that spiders where the only other thing on earth that scared him as much as this wasn't lost on Aaron but Spencer, though considering it weird if his expression was anything to go by, didn't appear to see the connection.

"Oookay!" Spencer said. He smiled reassuringly at Aaron before walking slowly over and leaning down to kiss him. It was comforting rather that arousing, though it served to ignite both.

When Aaron felt Spencer's tongue stroke across his, it was easy to forget about the troubling aspects of what was about to happen and consider only the man in his arms, who was now kissing like anything BUT a submissive.

The kiss was powerful, demanding, possessing. It was incredible.

"Scoot back." Spencer said simply. It wasn't a question and Aaron complied immediately, surprised by his own compliant behavior. Once again, thinking was rendered difficult by Spencer pushing him to lay down and pressing his body on top of Aaron's, moving his hips in small, teasing movements against his own. Aaron was moaning into Spencer's mouth, and he only wished he could run his hands through the soft, silky hair tickling his face.

It was then he realized Spencer was holding his wrists against the mattress. There was no pressure there, just enough of a touch to convey that he wanted Aaron to keep his hands there. Aaron was almost as confused as he was aroused, and he was dizzyingly aroused at that moment.

Spencer kept hold of Aaron's wrists as he slowly raised them up to he latted headboard. Aaron heard the cuffs before he felt them against his skin. He looked up to see his hands, not Spencer's, chained to the bed.

"What?" He breathed, pulling away from the kiss.

"You said you wanted this." Spencer said, breathless.

Aaron felt the lead weight in his chest lift as he realized Spencer hadn't actually specified who he wanted to be restrained. He laughed.

"I thought you wanted me to tie you up."

Spencer's eyebrows lifted for a second before his whole face fell, "Sorry." He said blankly while moving to remove the cuffs.

Aaron suddenly felt panicked, "NO!" he shouted. He didn't know why he reacted that way, all he knew was that the sight of Spencer sat above him while he lay here, completely at his mercy, felt so right.

Spencer came to this realization as well, and the way his face lit up made Aaron feel incredibly warm

"Okay." He smiled simply.

Aaron closed his eyes when he felt his lover move to kiss his neck, and gasped when Spencer bit the curve of his shoulder. His emotions were doing all kinds of things right now but there was one thing of which he was certain, he'd never been this hard in his life.

Panting, he could only breath, "Spencer. God yes." and lift his hips in a vain attempt to gain friction.

"Ah, ah." His lover whispered in a sing-song voice, "Patience."

"Please." God he was already begging.

Spencer sat up, straddling hiss hips and trailed his nails oh, so lightly down Aaron's heaving chest, "You are all mine tonight, and I'm going to take my time."

Aaron's whole body shivered at those words. "Yes."

He groaned in frustration when Spencer got up off the bed, but his eyes widened when he slowly started unbuttoning his shirt, "Do you have any idea how beautiful you look laid there like that? All hot and hard for me. So, so hard. Just waiting for my touch." He finished by letting his shirt flutter to the ground, before moving his hands to his pants. Aaron's hips jerked in response.

"Mmm," Spencer hummed, licking his lips, "I can't wait to taste you."

Aaron closed his eyes against the wave of heat those words caused. He had never been this turned on in his life.

"Spencer, please." God, he was desperate, how had he been reduced to this so fast?

His lover crawled back onto the bed slowly, completely naked, hard cock brushing his stomach. He was predatory, frightening.

Beautiful.

He traced his lips over his chest in a ghost of a kiss, barely touching, teasing. Aaron was purring. Eventually, his lover moved his lips to Aaron's nipple, captured it between his teeth and pulled.

"Agh! God." Aaron had never had his nipple simulated during sex before. It was incredible.

Inspired by the positive response, Spencer lavished attention on both nipples until Aaron was sure he was going to actually reach climax from nothing but this.

Eventually, Spencer worked his way lower while pushing down the boxers to his knee's and letting Aaorn kick them the rest of the way off. Then he was sucking on the smooth and sensitive skin of his abdomen

Aaron lifted his head and looked down only to see a dark bruise marking his hip. His lover having marked him in such an intimate place caused Aaron's throbbing cock to twitch.

Spencer bypassed his crotch and moved his mouth to Aaron's thighs, scraping his teeth. Aaron was panting, lost in arousal, and while he knew Spencer wanted to take his time, Aaron didn't think he'd last much longer.

Finally, taking pity, Spencer grasped Aaron's erection and slowly licked across the slit, lapping up the pre-come collected there.

"God!" Aaron cried, arching his body up when Spencer took the head into his mouth. He gradually took more and more of Aaron's cock in his mouth, sucking and licking along the underside. Aaron was thrashing and moaning, unused to this degree of pleasure.

He was so close when Spencer pulled away, probably having sensed that.

"What do you want Aaron?" Spencer asked huskily.

"You," That was the obvious reply, Aaron could tell Spencer wanted more, "I want you to take me." Aaron was surprised he'd actually managed the courage to say that out loud.

Spencer groaned and closed his eyes for a second, as though Aaron's request had caused him physical pleasure. When he opened them again, he fixed Aaron with a heated gaze, "You're sure." He asked, his voice almost a breath.

"Yes." Aaron replied with conviction. This was the first thing he'd been sure about.

Spencer moaned and laid his body down over Aaron's, both of them naked now, and kissed him. It was passionate and deep, tongues moving together and teeth clashing. He gasped when their cocks lined up, moving together. This was heaven.

Aaron heard the sounds of rummaging and realized when he heard a click that his lover had been reaching for the lube. When he felt the slick finger against his hole, he gasped. Spencer pulled away from the kiss and looked at him worryingly. Aaron shook his head and breathed, "I've never been touched there. It's ... god." His line of thought was interrupted when Spencer rubbed the finger over the muscle. It was so good.

Spencer grinned widely, before removing his finger and moving down his body, "I'm going to make you see stars right now."

As the genius disappeared down between Aaron's legs, he was just trying to breath. Suddenly those stars Spencer had promised burst before his vision. The feel of Spencer's hot, wet tongue stroking over at his hole almost made him pass out.

His entire body arched up off the bed when that sinful tongue breached him, it was so unlike anything he'd experienced before, it was so intimate. He moaned and writhed in response to the new sensation, he could go mad from such pleasure.

Much too soon, the tongue was gone, only to be replaced with a lubricated finger pushing inside him. Aaron had expected pain, but instead felt a not entirely unpleasant burning sensation. Any discomfort was immediately overwhelmed by pleasure when Spencer began sucking on his balls.

The pattern of overwhelming pain with pleasure continued until Aaron was pushing down eagerly on three long fingers and moaning wantonly.

"God, Spencer. I'm ready, take me now."

When his lover was in position, he looked him in the eyes, giving him one last chance to say no. Aaron kissed him, his beautiful, amazing lover, and whispered, "I want you."

The initial penetration hurt more than the fingers had, but it was still far from unpleasant. Aaron had his eyes closed, reeling from the feeling of being filled, taken, owned.

It was beyond Aaron's wildest dreams.

When he finally opened his eyes, the heat and raw desire he saw in Spencer's eyes blew him away.

"Aaron?" His lover's voice was strained with the effort not to move.

"Please." Was all he said, it was all that was needed.

If Aaron thought Spencer kissing him was magical, then the feel of him moving inside him bordered on celestial. But Aaron had only to open his eyes to see his angel.

"Do you want more Aaron?" Spencer's voice was deep and it sent a shiver down Aaron's spine.

Moaning, he managed to grunt, "Yes."

Leaning down to bite at Aaron's lip, his lover kissed across his cheekbones down to his ear, whispering, "Then beg."

'Holy fuck!' Aaron thought before he could articulate anything.

"Please, god. Please touch me Spencer. I need you." He was now lifting his hips to meet Spencer's thrusts, he was desperate to feel every possible inch of him.

All of a sudden, it was like something came free in Spencer. He raised up to hover over him, thrusting harder. "You are so hot like this. You're my little bitch."

"Yes."

"You're all mine." Spencer was looking him in the eyes as he said this, that mixed with the harsh thrusts was almost enough to undo Aaron.

"Yes."

Spencer growled, he actually growled, reached a hand down and slapped Aaron's ass cheek.

"Aah! Fuck, Yes!" Aaron had never been spanked before. He liked it.

Spencer's hips were slamming against his with a fevered pace now and Aaron felt like he was going to lose his mind if Spencer didn't touch him soon.

"Dear god. PLEASE!" He had resorted to screaming. His cries were echoing throughout the house and he was only glad Jack hadn't been able to stay the night. Spencer finally grabbed his heavy, throbbing cock and stroked roughly, an action made easier by the copious amounts of pre-come Aaron had released.

Pushed past any boundaries he could ever have had, Aaron came hard with a keening wail.

Spencer's arms collapsed when Aaron clenched around him and he murmured in his ear, "So hot. So fucking hot. Mine."

"Your's." Aaron whispered back and was rewarded when Spencer thrust hard once more, coming. He bit into Aaron's shoulder when his climax hit, marking him. Claiming him.

As the two laid together, Aaron still chained and Spencer still buried in him, Aaron knew this was where he belonged, where he wanted to be, completely and utterly at Spencer's mercy.

Aaron really was completely his. Forever.

End.
