Chapter 4

"I know," she said softly, the note of acceptance clear in her voice as she weighed the ramifications of letting him stay. She considered both options, a night of passion with a man she secretly loved and the heartbreak that would follow after they had satisfied their lust and returned to their professional relationship. Or the knowledge that she had done the right thing and sent him away, mixed with the heartache that would come from knowing she had missed out on her one opportunity to fulfill the fantasies she had indulged in on many a lonely night.

She opened her mouth to tell him goodnight and let him leave but couldn't speak the words, her body thrumming, arguing with her brain as she longed to feel his mouth on her again. She felt decidedly wicked as she made her decision and took a step back in his direction, hoping the look on her face was enough to show him her desire for his touch.

"Are you sure?" he asked, trying to sound confident even though his mouth was dry as he was bombarded with every fantasy he had ever had about her. The way she was looking at him he knew he wasn't going anywhere soon, he had become hers for the taking. No reason to keep fighting the attraction he decided as he took a step back towards her, his fingers moving to loosen his tie in the process just in case she wasn't absolutely clear about where things were going if she didn't put the brakes on it.

He noticed her hands were clenched at her sides, her toes curled into the carpet as he approached, her posture could have looked defensive to the casual observer but as a profiler he easily read the nervous anticipation she was feeling before he again pulled her close. He kissed her forehead and then let her go, holding his breath as he waited to be sure she had made up her mind. She showed no hesitation as she leaned up to kiss his chin before moving lower and kissing the pulse point beating rapidly at the base of his neck. He must have liked what she was doing she realized as she heard the noise he made low in his throat. So she did it again, savoring a moment of control before she knew he would again took over.

Hotch tilted her head back and gave her a kiss that left no doubt as to how much he wanted her. They moved away from the wall as he lifted her off the ground, his tongue plundering her mouth as she eagerly reciprocated as he made his way towards the hallway. Finally letting her down so she could guide him to the door of her bedroom. As they moved into the small yet neatly furnished room he lifted her off the ground again as he ravaged her mouth, responding as he felt her nails digging through the fabric into his shoulders. His hands shook uncharacteristically as he reached for the tiny buttons of her blouse. It was awkward for him as he couldn't stop kissing her long enough to pay attention to what he was doing. The process became even more complicated as she worked at trying to remove his shirt at the same time. She had gotten the row of buttons at the front of his shirt completely undone before she felt herself gently pushed away.

She could tell it wasn't a push of rejection but of much needed space as she again worked to catch her breath, her mind spinning as she thought that kissing had never caused a reaction like this with her before. Kissing Hotch was completely different than anything she had experienced before she thought, wondering if part of the reason was because of how emotionally invested in him she had become over the years or if it was just the stunning contrast of the softness of his lips against the relative firmness the rest of his body seemed to possess. Everything about him seemed to arouse her yet she needed to slow down she thought, to savor every moment of this one night with him. But at the same time she felt impatient, wanting him to hurry up and take his clothes off, to feel his skin against her own. As she kept her distance he unfastened his cuffs before removing his dress shirt and pulling his t-shirt over his head. Aside from the scars left by The Reaper his chest was all muscle. He was beautiful she thought before he pulled her back into his arms, kissing her again as he resumed work on the buttons of her blouse, eager to feel the softness of her bare skin.

The kiss he gave as he continued to fumble with the buttons on her blouse was hot and wet, again surprising her that every kiss they shared seemed to be better than the last as she felt herself melting against him as he pushed her towards the edge of the bed. He forced himself to stop kissing her long enough to go back to work on her clothes, determined to get them off and feeling tempted to rip the blouse with the tiny pearl like buttons that were so impeding his progress.

"Are you particularly attached to this blouse?" He asked, his voice husky as his large fingers continued to work with the unrelenting article of clothing.

"Not at all," she said with a ragged breath as she arched her back to push her breasts towards him, aching to feel his hands over her.

Taking her at her word he skipped over the buttons as he shifted his hands to the hem of her blouse and pulled, the buttons popping to the floor as the delicate garment easily tore beneath his strong hands. The blouse was the farthest thing from her mind as she felt the heat of his gaze settle on what he had just exposed.

"You're beautiful" he whispered as his hands slipped under the now ruined blouse to caress the bare skin of her flat stomach. His hands slowly circled her as she tried not to squirm under his touch while waiting for his hands to move higher. He showed a little more finesse with the clasp of her bra as he removed it along with the scrap of cloth that had covered her only moments before. When his hands at last cupped her breasts she trembled as she arched her back again, pushing into his palms as she reveled in the feel of the calloused hands against the sensitive skin, the peaks of her breast hardening almost instantly with the heat of his touch.

"God, JJ," he groaned as he bent to claim her mouth again, even as he continued to massage the soft flesh now filling his hands. The way she whimpered into his mouth as he kissed her drove him crazy as he pulled back again, his head dropping back to her shoulder, his breathing harsh as he finally managed to let go of her long enough to step back and remove the rest of his clothing.

He knew it was only a matter of minutes before he lost control and wanted her ready before he did that. "We've got to slow down," he all but growled the thought out. He meant what he said but then she moved to press back against him her breasts rubbed against his chest and suddenly slowing down didn't seem that important any longer.

They fell together onto the bed as he rolled her onto her back and nudged her thighs apart with his knee. Bracing his weight so he wouldn't crush her he loomed over her waiting body. He growled low in his throat from the pure satisfaction of finally having one of the many fantasies he had about her finally coming true. She looked disheveled and thoroughly aroused, her hair fanned across the pillow. Her face was flushed, eyes dark with desire and her lips still swollen from his kisses as she stroked his forearms, enjoying the heat of his body as it pressed against her own.

She watched his face in wonder, his expression so different than any she had ever seen at the office as he slowly trailed his fingertips down her neck, then lower to the hollow between her breasts. She saw him smile at the goosebumps left in the wake of his touch as his hands moved lower towards the lacy scrap of underwear that was the last barrier remaining between them that she wore. Ever so slowly he removed the pink lace panties as he studied the newly bared area. JJ battled her feelings of self-consciousness under his gaze, watching his face again as he began to stroke her stomach, then her hips as his hands continued south.

JJ almost came off the bed as she felt his large hand finally slip between her thighs. She couldn't remain passive any longer as she reached up to stroke the side of his face, feeling a hint of stubble on his jaw as she did so. Her hands began their own journey, caressing his neck and then his shoulders as she continued her own exploration. She could feel the heat of his body and the powerful muscles in his upper arms as she stroked muscles that were generally hidden beneath a stuffy suit jacket that she now realized had never revealed just how in shape their unit chief really was.

She knew she would never be able to look at him the same after this, now that she had touched him so intimately to now be aware of the texture of his skin and what was so often hid from the eyes of others. She took her time, hoping to drive him as crazy as he was driving her, determined to press on even though he seemed bent on continuing to distract her.

He was stroking her breasts again as he nibbled at the sensitive spot on her neck. She knew there would be a mark there the next morning but didn't care as she closed her eyes and arched her neck back before trailing her fingers to his stomach, feeling his abdominal muscles flex beneath her fingertips as they trailed down to her goal as she tugged at the waistband of his dress slacks. Glad he got the hint as he stepped back just long enough to slide them down, taking his boxers with them before hastily discarding them somewhere on her floor. He returned to her eagerly and resumed his attentions to her neck as ever so slowly her fingers circled his navel and then moved lower, wrapping her hand around him as he growled low in his throat.

He let her explore for as long as he could stand it before grabbing her hand, knowing if she continued things would end much too soon. Keeping her under him he returned to her mouth and kissed her passionately, his tongue rubbed against hers as his hands caressed her. He moved lower and kissed her breasts as he announced that he was going to kiss her all over. She couldn't find a voice to even ask him if he was serious as he set about his task. She heard herself moan as even with her eyes squeezing shut from pleasure she felt his mouth moving lower, tickling her stomach as he circled her naval with his tongue before moving lower still until he was touching her very center.

The pleasure she felt was consuming as her nails dug into his shoulder blades so hard she knew she was marking him as much has he was her. Her moans as she writhed beneath him sent his self-control into tatters as he yearned to be inside her. "Hotch," she groaned out his name at the loss as she felt him roll away, reaching for his discarded slacks and fumbling for his wallet.

"It's ok," he panted, "I just want us to be safe." He assured her as he hoped that he had remembered to carry a condom with him.

"I'm clean, and on the pill." She said as she watched him continuing to try and find the pocket to his trousers. Glad when he apparently took her at her word and dropped them and moved to rejoin her on the bed.

"Are you sure it's ok?" He asked again, obviously straining with the desire to be inside her.

"I trust you," she affirmed as he rolled back on top of her, kissing her fervently as he held her hands above her head with one hand while he again began to make love to her with his mouth. The first tremors of ecstacy caught her unaware as he was not even inside her yet when she felt them. She thought it might end there, but it didn't as the pleasure continued to grow, even as he slid a single finger inside her to gauge her readiness for him causing her to instinctively arch her back as she opened herself more fully to him. She felt the pleasure continue to grow in intensity to the point that it almost frightened her before he finally moved between her thighs, pressing into her gradually as he gave her body time to adjust to him.

She felt him come to rest deep inside her before he paused and began to retreat before pressing forward again. His jaw clenched and his control began to snap as she arched against him before wrapping her legs around him. The sensations were so overwhelming he couldn't slow the pace as she began lifting her hips to meet each hard thrust. When he finally climaxed inside her she was right there with him, calling out his name as she felt herself shatter before they finally collapsed against each other.
