Facing him, she knew this was going to be a lot of fun. Blood thundered in her ears and she forced to keep her breathing even. James had removed as much clothing as he could, mainly his dark hoodie so it wouldn't get caught on things. She bounced on her feet and removed her shoes; there was no need to cause actual damage to him! He had also done the same and she waited for him to face her. She was distinctly aware of the recruits watching them. She was so focused on what they were doing that the first tingle in her blood went unnoticed.

First thing he did was charge her, she stepped to the side, intending to follow that up with a kick to his shoulder however he stopped mid charge using the motion to step around behind her and land a blow on her shoulder. She twisted and followed up with a strike to his midriff. The smirk on his face was infuriating, as though he knew what she was going to do before she did it. The blow was blocked with his metal hand; a clang reverberating around the room. Natasha brought her knee up; this time she did catch his hip, avoiding more delicate areas – they were training of course.

"You're holding back," he said, a blow aimed at the side of her head. She ducked down and pushed with her knee, sending him backwards a couple of steps. Now it was her turn to rush forward, intending to clamp his neck with her legs and flip him on his back. She bit her lips as she moved; he seemed to anticipate what she was doing again however and caught her thighs in both hands, bringing her down to the floor and landing her on her back. He must have seen something flash in her eyes because his expression changed then. "Nat?" he said.

"We need to find somewhere." she whispered.

Nodding, he held out a hand and she got to her feet. Her legs were weak and shaking. She swallowed. "I'm ok," she said. It took a lot of her willpower to make her legs support her weight. "Now it's your turn," she said to the recruits, "Cap, will you excuse us for a moment," she said. She resisted taking a hold of Bucky's hand, instead she jerked her head and knew he was following behind her.

"You'll be back?" Steve asked.

"Give me a half hour," she replied over her shoulder. It was not like her to cut out of a training session but she knew Steve would forgive her for it, and also fill her in on how the rest of the session went. The moment they were out the room, she knew how bad she had let it get. The flush of the drug must have been showing in her cheeks and she frowned. How could they have done this to her? It wasn't fair and she didn't have to take it. A flush hit her that had nothing to do with the drug, heat colouring her cheeks and making her nose tingle.

"In here," she said. She pushed the door open and ushered James into the room.

"Nat, this is a broom cupboard," he said.

"I don't care." He had shut the door behind him, "I need you. Now," she said.

"Nat, you're going to have to keep it down, this is a cupboard not an apartment" he said. He had a valid reason of course but at that moment, she didn't care.

"It doesn't matter," she said. Her hand clenched in his shirt and his eyes darkened. Before she could stop him, not that she would, her back was pressed against the wall and his tongue was inside her mouth. His taste exploded into her mind and she was lost for a moment. Then she reacted; her tongue hit his in battle, her hands rested on his shoulders and she jumped, her legs encircling his waist.

His hand thrust into her hair, gripping the nape of her neck as he crushed her mouth with his. She could fee; his heart thudding through the thin fabric of his shirt, his breath crashed against her cheek and his touch was enticing, rough almost. "James…" she whispered into his mouth between kisses, "Now." His hand fumbled with the fly of his jeans while she shucked out of her pants. Her hand then found his prick and the noise he made threatened to give them away.

He did not speak, sealed her lips with his and shoved into her wet heat. His mouth swallowed her moan and his tongue battled with hers once more, thrusting deeply into her mouth as he pushed into her body. The feeling of fullness swamped her and she gasped, unable to move for a moment. He didn't give her time to really adjust to his invasion; his thrusting began immediately. Crossing her legs across his waist, she braced against the wall. One of his hands slammed next to her head, his mouth caught her ear, sending shooting sparks through her spine, "James," she hissed.

"You can't yell my name Nat," he said, his movements not slowing in the slightest. Her lips parted and she bit back another noise that may have given them away. She might not be able to scream but there was something she could do to prevent noise escaping; the bit his shoulder through the fabric of his shirt. It was his turn to hiss as he continued to pump into her.

She could feel every ridge of him, every stroke; feel his breath on her neck as he panted with the effort. Her legs clenched around him, moved along with him, her hands clung to his broad shoulders and she swallowed yet another cry. She felt the first build of her release in the base of her spine, a red feeling that rapidly turned to white. "I can't…" she hissed again. His hand clamped over her mouth and he increased the pace. Her entire world narrowed to the point where they joined and her vision began to swim.

A couple more deep thrusts and she felt him pulse; she was lost and for a long moment, she quivered around him, trying not to scream out what they were doing for the base to hear. When she came back to herself, they were both panting. The smile on his face was perhaps one of the cutest she had ever seen and she weakly patted his shoulder. He withdrew and took a step back, letting her slide down the wall until she was steady on her feet once again.

After straightening out her clothing and making herself presentable again, she turned to James and pressed a light kiss to his cheek, "Next time, I am going to scream your name," she said, knowing it was a little on the cheesy side but unable to resist the light tease. She was rewarded by a smile and she realised then that he wasn't an ugly fellow. He was rather handsome in his own way and that this drug might not necessarily be a bad thing. If they were going to continue to have sessions like that it seemed.

She watched him run a hand through damp hair and smirk at her, "Good to know, now we need to make sure we get out of here without people thinking we've been in here for a quick fuck," he said. The way he said it made her throat dry but she made no mention of that, no need to boost his ego too much!

"Wait here for about five minutes and then follow me out," she said. With that, she exited the broom closet and quickly shoved the door shut behind her. She could not keep the self-satisfied little smirk off her face. It did not occur to her then that she was growing rather fond of him, that would come much later on.
