Concussion Part Three

"Jess, I think that we need to t–"

Talk, Jess guessed he was going to say, but instead he cut off, staring round at their surroundings with wide eyes. He obviously hadn't looked at the room they were in until now... and now he saw where they were. Jess watched as he looked around at the walls, covered in shelves, and the various boxes and filing drawers that sat on those shelves.

Becker swallowed convulsively. "This... this is..."

"Storage Room 486-B," Jess said quietly.

Jess' heart was racing, but she felt oddly calm as she watched Becker swallow convulsively and dart his eyes away from her. She knew, dimly, that she should be freaking out right now, but instead she felt incredibly in control. Becker was clearly affected, and it was nice to have the upper hand for once. In fact, she had to fight the urge to smile.

She also knew that she would never get another chance like this one – a chance to force Becker into admitting how he really felt about her. But she had to play her cards right, or this conversation had the potential to ruin their entire relationship.

Becker was still not looking at her, and Jess saw his hands clench and unclench at his sides. She picked up a couple of files from on top of her pile and tried to look nonchalant as she put them away on the shelf behind her. She glanced back at Becker as she picked up two more – he was watching her now, his hands in fists. Jess paused for a moment to gather herself, before walking over to where Becker stood. His eyes widened to an almost comical extent as she stopped in front of him.

Jess looked at him. "Excuse me," she said after a moment. She nodded at the shelf behind him and held up the files in her hand.

"Oh!" Becker leapt to the side, and Jess bent over the shelf to put the file away, and to hide her smile.

Once the files were put away, Jess leant back against the wall next to the door and looked at Becker again. "So... you wanted to talk?" She said. She had to fight back the urge to smile again at the way Becker's mouth had fallen slightly open at the sight of her leaning back against the wall – the only part of the room not covered in shelves. He must have put two and two together.

Jess had never felt or acted so brazen in her life – and she was loving it.

Becker cleared his throat, his eyes darting away. "I – yeah, I think we should," he said. He looked back at her. "I just... I don't think we... I think we need to..."

Jess pushed off from the wall, keeping her eyes trained on Becker's. She guessed he wanted to look away again, but he didn't. "You think we need to...?" She asked softly. She cocked her head to one side. "What do we need to do?"

Becker just stared at her. Jess bit back a sigh and went to walk past him again, over to her pile of files. This was useless – he was either going to stammer out his reasons why they couldn't be together, or he was going to do a runner. She would have to finish her filing, go home to a big tub of Ben and Jerry's, and get to work on finding a guy who wasn't so emotionally stunted that he couldn't even admit he liked her. Well, she'd get to it after she... took care of some business. Because even if he was just going to stand there gaping at her, being this close to Becker two feet from where she'd imagined him pinning her against the wall was enough to leave her feeling decidedly... flustered.

But right now she should just get on with her filing, listen to whatever Becker was going to come up with, and then get out of there.

She was just walking past him, when she heard Becker swear. She'd heard him swear maybe twice in the entire time she'd known him, and always only in highly dangerous situations, so when he says "fuck" under his breath she can't help but look at him in shock. She doesn't have much time to process it though, because suddenly he was gripping her upper arm and dragging her towards him, just before his mouth crashed down on hers.

It had actually worked. It had actually worked! She, Jess Parker, had managed to get the almightily aloof Captain Becker so wound up that he was actually kissing her in a storage cupboard. She only had a moment to exult in the thought, though, because he was forcing her mouth open under his and she lost the ability to think about anything at all, except how reality was so, so much better than fantasy.

Becker let go of Jess' arm to grab her hips and pull him up against him, and Jess went willingly, wrapping her arms around his neck and pressing as close as she possibly could. He was all hard lines and strong muscle, and she could feel his erection already pressing against her belly. Heat crashed through her, pooling in her stomach and she clutched at him, her fingernails digging into his shoulders.

She felt herself tipping, her feet moving, and suddenly her back hit the wall and Becker was pressing into her even closer than before. Jess moaned her approval of their new position, one of her hands slipping under the collar of Becker's shirt to slide over the taut muscles of his back. His mouth was firm and demanding against hers, and she met him kiss for kiss, her tongue duelling with his. God, he was so good at this, but it wasn't enough – not nearly enough. She shifted her leg to the side so she was straddling Becker's thigh, and now his hip was pressing against her core, giving her some of the friction she so desperately needed, while her hip was pressing into his erection. Becker's lips broke from hers as he hissed at the contact, and Jess saw a glimpse of his eyes – predatory and darker than she'd ever seen them – before his head lowered so he could start kissing his way down her throat.

Jess' head dropped back against the wall behind her and her hand went to the back of Becker's neck, holding his head in place as he sucked on the spot below her ear. Becker's hands were moving too – one hand was braced on the wall beside them, but the other hand landed on her thigh, and was now sliding up her leg and under her skirt. Jess was practically panting with need, and her hand moved higher up on Becker's head, carding his hair between her fingers and raking her nails against his scalp...

"Argh!" Becker exclaimed, wrenching his head away like he'd been burnt.

Jess' eyes widened as she realised she'd completely forgotten he had stitches in his head.

"Oh god!" She exclaimed, completely mortified. "Oh god, I'm sorry!"

Becker wasn't pressed against her anymore, but he hadn't taken a proper step back either. Jess took that as a good sign, even as he reached up to inspect the wound on his head. "Are you okay? Are you bleeding?" Jess asked.

Becker shook his head. "No, I'm okay," he said. He dropped his hand again and looked at her. She bit her lip – still tingling from his bruising kisses – and gave him an apologetic look. To her great relief he reached up to cup her cheek and leant back into her. "It's okay," he whispered, before capturing her lips again.

Jess wrapped her arms around Becker's neck again and he pressed her back up against the wall, but their kiss had none of the urgency and passion it had had before. It was sweet and loving... and completely frustrating. She appreciated that she'd been stupid and hurt Becker just now, but she wasn't going to do it again... and if she did, he could handle it. He was a big tough soldier boy after all.

And hopefully she was about to find out just how big.

Except he wasn't deepening the kiss. He wasn't moving his hands. He was pressing against her, but he wasn't delving his tongue into her mouth like he was before or rubbing against her to create friction.

He was holding back.

Jess frowned slightly and pressed closer to him, her tongue pushing determinedly against his and her hand dipping under the collar of his shirt again.

Becker pulled away from the kiss.

"Jess..." He said quietly. Jess reached for him again, and he shook his head. "Jess – I can't."

Oh god. "I..."

Becker's eyes widened and he quickly shook his head again. "No, I mean – I can't have our first time be in a storage cupboard," he said.

Jess froze. "You... you're kidding me," she said quietly.

Becker started to step back. "Jess –"

Jess grabbed hold of the front of his shirt in her fists to keep him there, and glared at him. "You cannot kiss me like that and then not..."

"I'm sorry, but no," Becker said, cutting her off. He placed his hands against the wall either side of her, but didn't lean forward again. "I can't."

Jess didn't know whether to laugh or to cry. He wasn't rejecting her, he was just refusing to take this any further right now. She should be ecstatic right now – he had kissed her dizzy and seemed to be implying that he was definitely planning on doing so again – but she needed him to do that right now. There was no way she could just go back to work like this. She swallowed. "Might I remind you that you pushed me up against this wall just now?" She said.

"Well of course I did!" Becker exclaimed. He leant forward slightly, though not nearly far enough. "I haven't been able to think about anything else for two days!"

Jess' hands tightened around his shirt. "Then what's the problem?" She demanded.

Becker sighed. "It was the heat of the moment Jess," he said. He looked at her intently, and Jess felt another flash of heat course through her body. "Our first time is not going to be like this."

Jess swallowed again. "It's not?"

"No." Becker pressed up against her again, gently though, and leant in so he could whisper in her ear. Jess shivered as his breath washed over her. "Remember your fantasy of me in your room? It's going to be a lot like that," he said.

Jess' knees almost buckled. "I don't think I can wait that long," she said truthfully. Then, before Becker could move back again, she rubbed her body against the length of him, her hands sliding up onto his shoulders, her breasts against his chest, and her hips rocking against his still very evident erection. She felt him shudder, and pressed her mouth to his ear. "And I don't think you can either," she murmured.

"Fuck," Becker swore again. His hands moved back down to her hips. "Jess..." he groaned. His breathing had become heavier. "It's not that I don't want to... god." His voice cut off as she rocked against him again, her nails digging into his shoulders.

"Then what is it?" She asked.

Becker's fingers dug into her hips, but he lifted his head enough so he could look at her. "I don't care what you say... you – you can't actually want this," he said heavily.

Jess had to fight the urge to strangle his stupid, gentlemanly neck. Only Becker would listen to her telling him that she dreamt about this very scenario, experience her reaction to him pressing her against a wall, and then decide that she was actually far too delicate for such an activity. She thought of various choice names to call him, but instead she raised an eyebrow at him and reached down for his right hand. Becker's eyes were dark and intense as he stared at her, but he allowed her to lift his hand from his hip and push it down her leg to the hem of her skirt. His breath hitched slightly as she dragged his hand up her thigh under her skirt, and kept going until she pressed his hand against her mound. She let out a little gasp at the touch, and fought the urge to rub herself against him – her point was made with the first touch, as that was all Becker needed to feel how wet she was.

His eyes closed and he dropped his head forward so they were touching foreheads. "Fuck."

Jess lifted her hand from under her skirt and cupped the back of his neck again. His hand stayed where she'd put it. "You keep saying that, but I wish you just would," she said softly.

Becker lifted his head and removed his hand in the same instant, and Jess almost sagged in disappointment, before he suddenly drove his hand back down the front of her knickers and cupped her properly, skin on skin, and pushed his forefinger along her slick folds. Jess threw back her head and cried out, but Becker leant over her and swallowed her cry with an impossibly deep kiss. Jess could do nothing but cling to him as he pushed his finger up into her, and then another – she lost all control, scrabbling at his shoulders for purchase and rubbing herself against his hand.

Becker withdrew his fingers and shifted his hand around, and started to tug at her underwear. They got caught on her hip but before Jess could move to help him, he reached down his other hand between them and she heard a ripping sound.

She almost came right then.

Instead she took advantage of the space created between them to reach for Becker's belt buckle. They broke off their kiss, too intent on removing the obstacles of clothing between them to pay attention to anything else. Jess made short work of Becker's belt and the buttons on his fly, while he was working on the buttons at the front of her dress, parting the front of it to get to her breasts. Jess pushed at Becker's trousers and the waistband of his boxers, pushing them down over his hips so his erection sprang free. She reached for him, but he intercepted her hand, tangling her fingers in his own as he lowered his head to the top of her breasts. Her free hand went into his hair again; Becker groaned and she felt him bite her slightly – perhaps she'd grazed his stitches again. He didn't pull away this time. He let go of her hand and settled his hands on her thighs, pushing them apart and moving to grip her backside, then lifting her up off the floor and pinning her against the wall again. He lifted his head from the top of her breasts and slid up her body as he lowered her down onto him.

Jess dropped her head back against the wall, groaning at the exquisite feel of him within her. Becker pressed an open-mouthed kiss to her neck, his teeth grazing slightly against her sensitised skin, and Jess raised her head again to look at him. His eyes were darker than ever, and boring into hers – he wrapped one arm around her back and braced one hand against the wall, and she wrapped both her arms around his neck.

The moment he moved, Jess knew it wasn't going to take long. Nothing had ever felt so good, and thanks to the build up she was already so close to the crest of her orgasm that she was surprised she hadn't tipped over the top already. Judging by the way Becker was panting and swearing in her ear, he was feeling pretty close to the edge as well.

They found something of a rhythm, only to abandon that to wild, shallow thrusts that built with intensity as they both drew each other nearer to the edge. Jess met him move for move, using her arms and the wall to lever herself against him, and she moaned with every single movement. She was close, so close, and Becker started saying her name in her ear, over and over. The sound of it was enough to send her over the edge, and her head dropped back again as she rode out the most intense orgasm of her life. Dimly she heard Becker cry out her name one final time, along with a string of swear words, and felt his arm around her back tighten almost painfully.

It was a good minute before she could think properly again. Becker still had her pinned against the wall, her legs wrapped tight around his waist. He was still inside her, and his head was buried in the crook of her neck. She smoothed a hand over his hair – carefully – kissed him on the cheek. He raised his head and kissed her properly, but sweetly... this time, Jess didn't mind the sweetness at all.

Becker braced Jess against the wall as he pulled out of her, and she lowered her slightly wobbly legs to the ground. Becker was pulling up his trousers and sorting himself out, so she did the same – buttoning up the front of her dress and reaching up to smooth down her hair. She looked at the floor and saw her discarded, ruined underwear lying by her feet – she quickly reached down to pick them up.

When she straightened up, she found Becker staring at her.

"That... was..." He started to say, and Jess grinned. Amazing, she thought. Perfect, fantastic, the hottest experience of my life...

"Insane," Becker finished. Jess' eyes widened, and Becker gave her an incredulous look. "We didn't use any protection."

"I'm on the pill," Jess said immediately.

She had a feeling Becker knew that already, because he didn't look surprised. But he wasn't finished – Jess knew what he was doing; despite her practically begging him to, he felt bad that their first time had in fact been in a storage cupboard and was trying to find something to grouch about... since he couldn't grouch about the actual, fantastic sex part. Jess wondered when she'd got to know him so well.

"Someone could have heard us," he said tersely.

Jess shook her head. "I doubt it – the walls and doors in here are pretty thick," she said.

"We didn't even lock the door! Anyone could have walked in!" Becker exclaimed.

Jess rolled her eyes. "But they didn't."

Becker didn't look too impressed with her reasoning. "This time," he said.

Jess couldn't help but smirk. "So there's going to be a next time?" She said coyly.

Becker was in front of her before she could blink, and the next thing Jess knew he had her wrists pinned against the wall either side of her head and his body pressed against the line of hers. She dropped the underwear she'd been holding back to the floor.

"Let me tell you something, Jessica, you're not the only one with fantasies," Becker said, his voice low and his eyes boring into hers.

Jess' didn't know how she could get so turned on again so quickly and so soon, but god she really was. She swallowed. "I'm not?" She gasped out.

Becker quirked an eyebrow at her. "No." He let go of her wrists and stepped back, leaving Jess to slide about a foot down the wall as she sagged against it. Becker bent down and picked up her ruined knickers, and then gave her another intense look before tucking them into his trouser pocket.

"And believe me, you're going to learn every single one of mine, very, very soon," he said.
