AN: Loki gets a bit domestic... and then territorial.

It was evening and you were headed back to your apartment after a rather busy day at work. One part of your day had consisted of the mundane task of developing a better firewall for Stark's pet project on planetary safety, while the other consisted of trying your hand at bettering your self-defense skills. Natasha Romanoff was your self-appointed mentor, and she was quite invested in making you learn some complex hand-to-hand combat moves.

You discovered that you weren't a total loser in terms of moving your body fluidly to avoid the obvious attacks, but you were not so good with skilled, deceptive attacks. But then again, as Natasha had stated with an indulgent smile, you were essentially a Padawan and there was a long way to go towards becoming a Jedi.

It was a crazy thing to learn that the menacing Black Widow was a nerd who liked to make Star Wars references. Not that it made her any less dangerous or effective in her line of work, just that it made her more friendly and approachable in your perspective.

The more you interacted with her, the more you ended up liking her. Maybe there was a friendship on the horizon…

The moment you stepped into your apartment, you were bombarded with the smell of Italian herbs… and assaulted with the view of a shirtless Loki eating pizza in your living room.

"You're back," you stated lamely, mentally admonishing yourself as captain obvious in the same breath. Of course, he was back… you could see him sprawled on your couch, manspreading as much as he could.

"As you can see," he responded, then bit off a huge chunk of the pizza slice in his hand. Somehow, he made it look elegant. "The mission was completed earlier than estimated, owing to my skills as a mage."

Oh arrogance, thy name is Loki.

"Where's your shirt?"

He smirked at your question. "Destroyed amidst the chaos of the mission. Midgardian fabrics cannot seem to keep up with me."

You vacillated over asking him why he was in your apartment instead of his own… but then you simply shrugged it off. There was no point in asking him. He did what he wanted, regardless of whatever anyone else thought of it.

Loki made a gesture with his hand for you to come over, and you found yourself heeding that command without a second thought. When you reached him, he simply pulled you on to his lap.

"Indulge yourself," he said, retrieving another slice from the pizza box sitting beside him. He offered it to you and you took a hesitant bite.

That's basically how your dinner time played out, with Loki feeding you and himself from the comfort of your couch. He didn't let you budge from his lap, and eventually, you stopped squirming and got used the feel of sitting on his muscled thighs.

There was a sense of déjà vu in all of this…

"I need to take a shower," you said as you watched him finish the last of the pizza.

"Me too," he replied, and the suggestion was obvious in his voice and demeanor, as his hand caressed your neck and his eyes all but undressed you with their intense perusal.

And involuntary shiver ran down your spine, accompanied by a flush of arousal. Well, it had been a few days since you saw him, and quite honestly, your lady parts were missing him sorely.

You made to get up from his lap, and this time, he didn't stop you. You could feel his eyes on you as you walked to your bedroom.

Feeling a flash of boldness, you slowed you pace and began taking off your clothes. First the top was discarded, then the skirt. You didn't know why you wanted to tease him… you just wanted to.

As you entered the bedroom and kicked off your shoes, Loki was right behind you. Your bra and panties were gone in seconds then, as were his own clothes. Moments later, you were both standing under the spray of the shower, and his mouth was busy owning yours in a heated kiss.

You pulled away with a gasp, your lips feeling puffy and swollen. "Loki, not here please. I'm too tired for shower aerobics."

Even as you said that, you felt your pussy growing wetter. It seemed that your body didn't quite agree with you there.

You fully expected Loki to simply grab you and impale you on his cock, which was presently standing at full mast and bobbing at you in greeting. When he didn't do that, you looked up at him in confusion.

"Give me the soap." He turned the shower off and extended his hand towards you. Dumbfounded, you handed him your body wash.

You spent the whole of the shower merely gripping the fixtures or the wall as Loki washed your body and shampooed your hair. It was extremely sensual, but not sexual in the way you had assumed it would be.

You were so thoroughly confused, and it showed, as you watched him while he washed himself. He simply smirked at you and carried on.

That cock was still very hard and still bobbing at you for attention, though.

And you wanted its attention, regardless of your tired state. What a turmoil to have…

Loki insisted on drying you, or rather… teasing you, as he brushed the towel gently against all the sensitive areas of your body. At first, you took it all silently. But then, as he carried on, your patience ran thin. Or your lust just took over.

You reached for his erection and grasped it firmly, though your eyes couldn't quite meet his as you did so.

You expected some kind of reaction from him, but he remained silent. Infuriatingly silent. He did stop rubbing the towel against your body.

Slowly, holding him by his cock, you pulled him to the bed. A glance up at his face showed that he was amused by your actions. As you sat down on the bed, his manhood was right in your face. Literally.

So you did what you thought might provoke some kind of reaction in him… you wrapped your lips around its tip. You weren't very well versed in this particular skill, and quite honestly, his sheer size was making you nervous. You may well have bitten off more than you could chew.

"Mmm… I thought you were too tired?" he asked, his voice huskier than before.

You didn't respond and just kept sucking. A tug at your hair made you look up at him.

"It is rather remarkable how a few caresses can be promises of pleasure, isn't it?" His voice was raspier now, clearly affected by what you were doing, and you counted it as a small victory over his cockiness. "Or shall I say that I've made a wanton woman out of you?"

You cupped his balls then, and he uttered a low hiss. You would've chuckled if you could…

Suddenly, you were pulled away from his cock and tossed on your back. His head was between your legs before you could close them, and his tongue was working your pussy into a frenzy before you could even fathom what was going on.

A squeal of surprise from you, a growl of dominance from him… and just like that you were back in your usual dynamic, getting off on his dominance.

Loki kept your legs spread wide open as he gave you orgasm after orgasm. The pleasure was so intense that your legs were shaking by the time he was done making you squirm on his tongue.

"Feeling better now?" he asked as he crawled up over you and entered you in a slow thrust. Your legs immediately locked around his hips, as did your arms around his shoulders.

"Better?" you asked, and it was kind of distorted in your moaning. "W-What?"

"You said you were tired," he grunted, thrusting very leisurely, drawing your pleasure out.

"I… yes, but—" he stopped you from saying more by sealing his lips over yours, kissing you so thoroughly that you forgot what you were about to say to him.

The kisses never really stopped, barring a few instances where he was keen on giving your chin and neck a couple of love bites. Your lips knew only one word—his name—as he fucked you into a state of near constant pleasure.

Somewhere amidst your gasps and cries, you felt him throb inside you and release, accompanied by his deep groans of sexual culmination. God, those were such sexy sounds…

Your eyes were beginning to droop by the time he calmed, but he didn't pull out. He turned slightly, keeping you joined with him, and kept grinding into you.

"I'm sleepy," you mumbled against his lips. It was a kind of half assed complaint, though, since you were actually liking what he was doing to you.

It was fucking, but mixed with cuddles, as he held you close while his cock kept sliding in and out of you.

"Hmm, I noticed." One of his hands cradled your ass, holding you firmly against him. "But I think you're still capable of another climax."

"No…," you muttered, closing your eyes.

"Yes," he countered, changing the angle of his thrusts to hit that sweet spot inside you… the one that immediately drove you crazy with pleasure. "Be a good girl and come on my cock one last time."

"Ah Loki!" You arched your back and contracted around him, just as he commanded. It was kind of humiliating that your body followed his orders like a well-trained pet, but damn, it felt so good!

Sleep claimed you soon after, but not before you felt him climax one more time, taking all the pleasure from your body as he could, given that you were basically a sleepy ragdoll in his arms.

You were in the lab, feeling surprisingly fresh despite whatever sexual shenanigans had gone down last night. Loki was most probably responsible for that, and you felt begrudgingly grateful to him.

You weren't feeling all too grateful about him bickering with Stark, though.

"My magic is a combination of several complex mechanisms Stark, some of which your science cannot even fathom, let alone name."

"Oh yeah, how about you enlighten us peasants, then, Jafar."

Loki frowned at the new nickname, while you barely kept yourself from snickering. Stark seemed smug about it, but thankfully didn't go on in the same vein.

"No really, explain at least some of it in the terms we can understand. After all, your pardoning is dependent on you helping us puny humans out, no?"

Oh, now Stark had stepped into a very bad territory with Loki. You could almost feel it happening; like a change in the air pressure inside the room.

Loki's body stiffened and he gave Stark a glare that couldn't be compared in human terms. It was dark and menacing, and a good reminder of the fact that Loki was not human at all. It made you want to leave the lab and run, even though you weren't its recipient.

"Whoa!" Stark took a step back, clearly feeling the heat of Loki's glare. "Calm down, Loki, we're all trying to help each other here."

It was perhaps one of those rare occasions where Stark was feeling off-balanced enough to not call Loki by any of his given nicknames.

"I didn't threaten you, did I?" Loki asked, his voice deep and raspy, making you think of a snake coiling itself.

His demeanor was still very rigid and combative, something you hoped Stark took note of. You didn't want the lab to be destroyed as yet.

"I think it is pretty much clear that his form of teleportation takes into consideration the stability of the atomic particles at the point from which he disappears and at the point of his appearance," you stated, making your observation at possibly the most inopportune time.

You did hope that it distracted both of them enough to make them forget about their one-upmanship.

"Are you into astrophysics, Matrix?" Stark turned to you with surprise evident in his eyes. Loki's gaze also flickered to you, and he immediately toned down his glare.

"I'm into logic and deduction," you replied with a shrug. "When Loki teleports from one point to another, he doesn't even create a draught. So, I think it's safe to assume that he's somehow maintaining the stability of the packet of space he's utilizing."

"It's a necessity," Loki said, staring at you in a weirdly assessing way, quite unlike his usually sexually charged gaze. Then he turned to Stark once again, giving you a breather from squirming under his intense regard. "Stealth is one of the benefits of this method of travel. Why would I compromise that by destabilizing the particles of space?"

"I don't know… dramatic supervillain entry?" Stark quipped, and you felt like hitting your forehead with your palms.

Loki seemed poised to give him a scathing remark, but he was stopped by the chiming of Stark's phone. Stark picked up the call and went sauntering out of the lab, much to Loki's irritation.

The moment Stark was out of the lab, though, Loki's ire eased somewhat. He turned to look at you, but you kept your eyes down at the computer screen.

You heard the taps of his boots as he came closer and stood beside you.

"Your observations were impressive."

"Thanks."

Awkward didn't even begin to cover how you felt at the moment. Loki praising you for your brains and not anything sexual? WHAT?

"You never told me what had you so tired yesterday?"

"Just… work stuff." You typed in a few commands as you spoke, still not looking at him.

Briefly, you did wonder why you were keeping this small detail from him. You just felt like it. After all, it wasn't like he was your boyfriend or anything…

The lab door whooshed opened then, and instead of Tony Stark, Natasha Romanoff came rushing in. Not the timing you were expecting. Clearly not a good timing.

"Hey golubushka," she said, winking at you as she handed you a flash drive. "Something to help your endeavor."

Beside you, Loki stiffened, though he didn't make any comment. Natasha didn't even acknowledge him. She simply hooked an arm over your shoulder and kept talking.

"So, how are you liking the training sessions?"

"They're good. I'm learning a lot. Thanks," you responded, feeling rather weird with the way she was being so touchy-feely with you.

She was still intimidating as hell, and you weren't sure what to make of this over-friendly attitude of hers.

"I'm glad. I see potential in you. Not as an agent, but as someone who can be trained well."

"Okay, that's good to hear."

You weren't sure how, but you could feel animosity rolling off Loki in that moment.

"So, you're coming down to the gym in the evening?" she asked, quirking an eyebrow as she spared a glance at Loki. You weren't aware of what he was doing, as your attention was on Natasha. You just hoped that he wasn't doing something untoward.

"Sure, see you there." You smiled, and she responded with a one arm hug… with the same arm that was hanging over your shoulder.

"Can we go on with the experiments or am I to endure endless chatter as I waste my time here?" Loki asked, his voice cold and sharp as knives.

Romanoff rolled her eyes but didn't reply to him.

"Your hair smells nice," she said to you, and then breezed out of the lab as swiftly as she had entered. Was that a parting compliment? You considered it one. There was no other explanation for it.

"You didn't tell me that Romanoff was teaching you combat skills."

Uh oh…

You turned to face Loki, who was glaring at the lab doors like they had personally offended him.

"I wasn't aware I needed to," you said, kind of feeling defiant, given that he considered it an obvious step to tell him about all your plans and activities beforehand.

His attention came back to you then, and his eyes narrowed. "Let me make you aware then…"

Loki grabbed your arm and pulled you close. It wasn't a harsh grip, just very firm. You weren't sure what he was about to do, and that made you nervous as hell.

Just then, the lab doors whooshed again, and Loki let go of you in haste. Stark walked in, eyes still on his phone, completely oblivious to the tension in the room.

"What's up, kids, hope you didn't break any of my toys here," he commented casually as logged back on his computer interface. "Rock of ages, you calm now? Shall we begin again?"

Loki took his position inside the enclosure for the experiments, his face now impassive instead of angry. "Go on, Stark," he replied with obvious annoyance, "just have to endure this."

"Ouch… you hurt my delicate heart." Stark held a hand to his heart, which glowed an eerie blue because of the arc reactor.

Loki rolled his eyes but didn't say anything more, he simply stared ahead, ignoring Stark… and you. That bothered you, in more ways than one.

Leave me a review if you liked it.
