Chapter Text

“Stop looking so guilty, all you're doing is dancing with your brother-in-law.” It was the first thing of any real substance he had said to her since before the ceremony, but they hadn't been alone to discuss the… incident… until now, when she was working her way through letting everyone at the reception dance with the bride.

“I don't look guilty,” she replied. She spoke quietly, just as he had, to avoid being overheard by any of the nearby dancers. This was not the kind of conversation to be shared.

“How would you know?” he asked, not unreasonably.

Now she spoke with more confidence, “You don't look guilty.”

“That's because I'm a much better liar than you are.”

“Does that mean you feel guilty?”

“Of course I do,” he answered, and she felt her face flush with the implied reprimand. Her gaze dropped, her eyes fixing on his shoulder. His hand around hers felt hot, but she was probably imagining that; his touch burned now because it was explicitly forbidden after her marriage vows in a way it hadn't been before.

Perhaps if it had been they wouldn't now be worrying about looking guilty while dancing at the reception. An hour ago she had only been betraying a fiance, now she would have to deal with a divorce if she made the same mistake again.

“You know it's not going to happen again, right?” It seemed obvious but if it wasn't then it needed to be said, to make her decision clear.

“I had assumed it wouldn't,” he answered, with an edge of irritation in his voice and in his words. “You were anxious about making such a big commitment and it made you briefly and uncharacteristically slutty.”

Now she glared at him; “That's some double standard you have there.”

“I wasn't about to get married.”

“No,” she shot back, “but your brother was.” She sighed and shook her head. “We can't fight like this, we need to move on. We should just pretend it never happened.”

A moment passed where she worried that he would reject her offer and make a scene, ruining everything. “You're right.” He smiled at her, signalling a willingness to cease hostilities. “We'll put it behind us. Forget about it entirely.”

She nodded and she smiled back at him. With luck, no one would know what the two of them had done shortly before she had married his brother, or that her husband would not be the first man to make her come on her wedding day.

**

She had made herself think about it, that was the problem. She had put the idea in her own head by doing it once for what had seemed like a good reason, and now she couldn't not think about what they had done and what else they might do, hypothetically, if she wasn't already married to someone else.

Unfortunately, being married to that specific someone else brought her into contact with Loki a lot; he and his brother socialised together often, and now that Jane was part of the family the two of them couldn't really avoid each other.

The three of them had gone out for Sunday lunch at a favourite pub, and this time she was seated across from Thor, next to Loki in one of the high-backed booths at the back. This should have been fine, if her new brother-in-law could have trusted not to misbehave.

One hand was holding a pint, the glass held securely with long elegant fingers - a sight that captured Jane's wandering attention until she felt a weight on her thigh and realised that his other hand had settled there. When she looked up, surprised, he wasn't even looking at her, nor did he glance in her direction when without a word she moved his hand from her leg.

It was a game to him, this kind of thing. He liked playing stupid little jokes on people. It wasn't intended as anything but an annoyance, and the traitorous thoughts it put into her head could not have been the aim of whatever he thought he was playing at. She was the one making it a lot more serious than it really was. It would be best to ignore it, which was what she resolved to do.

She failed, though she really did try. She couldn't get him out of her head, and when the hand returned ten minutes later, this time just above her knee, she knocked it away so quickly that it must have betrayed how affected she was by all of this.

She fumed silently until she took the occasion of Thor going to the bathroom to confront his brother.

“This isn't funny,” she said. “It's not appropriate either.”

He didn't answer right away, taking a drink before answering her. “Why does it have to be a joke?” he asked. “Didn't it occur to you that I might want another bite of the forbidden fruit?”

Just like she did. But she shook her head. “We agreed to forget about that.”

“And have you forgotten?” he asked. He lowered his voice, “Did you make yourself forget how it felt to have me inside your…” He stopped talking, having spotted her approaching husband.

Jane felt trapped and exposed. She was sure the guilt of what she had done and of what she had considered in the months since the mistake at her wedding must be obvious to everyone. She only accepted that it wasn't when Thor failed to confront her about it. The rest of the outing passed with her in a mental hell of her own making, but at least Loki’s hands didn't stray again. He must have had his fill of that little joke.

**

Thor was just off the phone when she got home from work, giving her the news as soon as she arrived.

“Loki's roof fell in, so he's going to be staying with us until it gets fixed.”

She answered on instinct; “Does he have to?”

Thor was surprised by her response. “It shouldn't be more than a few weeks. If you really don't want him here he could stay in a hotel but I thought you two liked each other. Have you fallen out?”

She shook her head and accepted the inevitable defeat – telling the truth might keep Loki out of the house but it would almost certainly mean her leaving as well. “No, I just wasn't expecting it. You're right, he should stay with us. He's family.”

Thor looked relieved. “I'll go and pick him up, can you get the spare room ready?” When she nodded, he kissed her. “Thanks, I'll make it up to you somehow.” He kissed her again, and added, with a flirtatious wink, “Try not to make too much noise when I do, eh? We don't want to disturb our guest.”

The next few weeks were going to be difficult.

Chapter Text

After a few initial days of good behaviour that almost had her dropping her guard, Loki proved Jane's instincts right on the first Saturday when Thor went out to run some errands and the two of them were left alone for a while.

“How's being married working out for you?” he asked, as soon as he could safely do so.

“It's great,” she said, and it was true – other than an occasional moment of temptation the relationship was going well.

“Does he satisfy you? Sexually?” He asked her this so casually that she took it as another stupid joke.

“You shouldn’t ask me things like that,” she told him, trying to stay calm.

He grinned. “I'll take that as a no.”

“Take it however you want, but I didn't actually answer your question.”

“I'd make you come before I fucked you,” he said calmly, like he was making an observation about the weather, “and then you'd come again with my cock in you.”

“Stop,” she said, but he ignored the warning, leaning a little closer to her to tell her the rest.

“I'd fill you so full, Jane. Leave you dripping. Maybe leave something more than that in you… Are you on the pill?”

She was angry but she was also unconformably aroused, which made her angrier still. “You can't talk to me like this.”

“I just did.”

“I'll tell Thor.” It was a poor threat and they both knew it.

“Are you going to tell him how wet it gets you? That you can't stop thinking about me fucking you again?”

She lashed out, slapping him across the face with a gratifyingly loud sound as her palm hit his cheek. She hit him so hard that it stung her skin.

He stared at her, left in no doubt that he had gone too far and crossed a line.

“Never speak to me like that again,” she said, coldly. She started to stand, ready to storm out of the room, but Loki caught her by the wrist.

“I won't.” It surprised her that she had won so easily, but he looked contrite. “You're right, I shouldn’t say things like that. Ever feel like you can't control the things you do?”

All the time. Right now she couldn't control the heat rising in her despite their argument, and despite the fact she really was happy with her marriage.

“I don't know what you mean,” she lied, pulling away from his grip. She stared him down until he shrugged and sat back on the sofa.

“Maybe you're just a better person than I am.”

She hoped she was. She was probably going to have to be the one to put the brakes on it if things got too friendly while he was here.

As if to confirm that, he added, “I wasn't lying about making you come though.” He didn't look at her when he said that, his attention now supposedly on the TV again.

She believed him: he had done it before so he could do it again. All she had to do was let him, which was at once impossible and worryingly easy.

**

Jane had been married for less than six months and was convinced that she should still be thinking of her husband when she masturbated, but this time she wasn't. She wouldn't even have been touching herself right now if she hadn't found her thoughts straying towards another man.

Loki was wicked sometimes, but so was she, though she had never been so aware of that as she was now, with temptation closer than ever, living in her home while his own wasn't fit for its purpose.

Reclining in the bath she put a hand on her thigh where had touched her two weeks ago, imagining that she would let him do it again and that this time - being imaginary - he would touch her in exactly the way she wanted. Her own hand was too small and too light for the heavy touch she wanted, but it was close enough to let her invent a fantasy. He would move his hand higher, creeping up her leg slowly, and she acted out the movement in reality. She'd let those long, clever fingers explore between her legs, rubbing and lightly pinching at her clit, and as soon as she was wet enough for it they'd slip inside her as well, stroking her from the inside.

She closed her eyes and imagined him fucking her with his fingers as her hand moved beneath the bathwater, her legs parting and her hips pushing up to meet her own touch. She shook as the climax hit her, head back and gasping, letting the pleasure pulse through her body, slowly fading to a relaxed state of physical contentment.

The guilt lasted only a little longer, and was less intense.

**

She really hadn't intended to end up in the spare room, where Loki was currently staying, but she had gone to the bathroom and then her feet (or something else) had led her here without her mind making the decision. Or so she was telling herself.

Loki was reading by the light of the lamp on the nightstand. He looked at her, silent, and then he reached out and turned down the covers at his side, opening up the space in what was obviously an offer of the kind he should not be making her, especially not while sheltering under Thor's roof.

Jane should have declined, left the room, done her best to pretend that none of this had ever happened. Instead she crossed the room and slipped between the sheets, her traitorous heart racing.

“Is he asleep?” The words were soft, quiet, discreet. She nodded and Loki set aside the book he had been reading and turned towards her. Without another word he kissed her, a hand already slipping under the t-shirt she had worn to bed.

Jane accepted the kiss and let him turn her onto her back with him above her, pretending for now that none of this was her own doing. She kept her hands at her sides to keep up the charade, and though her body arched upwards and her mouth let out quiet sighs and moans between kisses she could convince herself that these were simply instinctive responses to intimacy.

She was not the only person in this bed who needed to be convinced, but she was probably the only one who was convinced. The hand under her clothing moved to her breast, rubbing a thumb across the nipple until it peaked, and the kisses had become deep and heated.

She should have left the bed already. Things could only progress in one direction if she stayed, but stay she did. She didn't want to leave, she wanted these touches on her heated skin, she wanted the hardness she could feel pressing against her thigh.

This was all way too risky; the door wasn't locked and at any moment her husband might wake up and come looking for her. The thought made her moan into her lover's mouth and spread her thighs for more forbidden pleasures.

They would have to be quick if they were going to avoid getting caught in the act. She guided his hand to the waistband of her pyjama shorts, still reluctant to do too much that was undeniably her own action. She got her way despite the lack of spoken instruction; in mere moments she was bare below the waist, and she didn't have to wait much longer before he was pushing into her, filling her without her having to give verbal permission.

She was happily married. She loved her husband. She had his brother’s cock in her while he slept in the next room. It was all so wrong and she had never been so turned on in her life. She was on the edge already and it wouldn't take much to tip her over. The quick, determined thrusts she was still pretending to accept rather than encourage told her that at least she was not alone in her depravity. They became faster when she came, her cries muffled by her fist, and the bedsprings sounded loud enough to betray them before the noise stopped suddenly and Loki groaned, spilling deep inside her.

She had no idea what to say when they separated, so she said nothing, just pulled her clothes back on, her shorts at once wet with the results of their illicit activities. She left the bed without speaking a word, and then she left the bedroom still silent. She slipped back into her own bed and lay on her side, turned towards her husband in the darkness, her heart still beating fast and her cunt still throbbing with the pleasure she had stolen.

Chapter Text

The next morning she ventured from her bedroom, wary of the conversation she would need to have at some point, and reached the bathroom just as Loki was leaving it. They stared at each other in an awkward silence until he stepped aside to let her into the room. She held her breath as she moved past him, afraid of some accidental contact, and locked the door as quickly as she could, leaning back against the door until she had calmed. 

They would have to talk at some point to address the previous night's lapse into adultery and ensure that it never happened again. While they were living in the same house there would always be a chance of them finding themselves alone together and then…

And then nothing, except that Jane no longer trusted herself to do nothing now that she had so eagerly indulged in something and knew how good that something could feel.

Breakfast was no better – he sat with a bowl of cornflakes making small talk with Thor and ignoring her beyond an occasional furtive glance. She was inclined to do the same and hoped it wouldn't make Thor suspicious.

She left for work with the unheld conversation hanging over her and with the memory of the previous night still fresh in her mind.

**

They would need some privacy if they were going to talk about having had sex with each other and that was difficult to secure while all three of them were in the house. 

Losing patience, Loki took hold of her arm and pulled her into her home's tiny utility room, shutting the door behind them. There wasn't a great deal of space available and with a single step towards her he had her backed up against the wall.

She had hoped that he would take the lead on putting a stop to this affair before it really got started, so that she wouldn't have to rely on her own resilience as much, but she was to have no luck on that front.

“I couldn't stop thinking about you at work,” he told her, one hand on the wall behind her, blocking her in against it, his position and his superior height making Jane feel much smaller than she knew herself to be. “About what we did. I had to sneak off to the bathroom for a quick wank to clear my head.”

She would have been happy not to have that information, but now that he had shared it she could not deny that she liked the idea of being so desirable to someone. Most people would not have told her they had done that, but that was the unfortunate appeal of Loki – he seemed to lack respect for basic social rules like keeping his masturbation habits to himself and not having sex with his brother's wife. 

She didn't reply to what he had said, but her body flushed hot in response and she ached to have something - to have him - inside her.

He was so close, she would barely have to move to kiss him. They were almost touching already. Jane was not optimistic about her chances of doing the sensible thing and leaving the room with an agreement to pretend that they had done nothing the night before. 

“We shouldn't…” was as far as she got towards that goal, and she lost the will to insist when she felt his hand on her hip and he leaned down, mouth hovering just an inch away from hers. 

“Not here,” she said, keeping her hands pressed against the wall in case an attempt to push him away ended in her pulling him closer instead. “Tonight,” she promised, before she had the sense to stop herself. “Wait up for me, I'll come see you when Thor's asleep.”

After a pause that seemed about to turn into an objection, Loki nodded. “Tonight,” he agreed, kissing the corner of her mouth before pulling away again. He traced her bottom lip with his thumb and shook his head. “It's going to be a long evening,” he said, and she stayed stock still against the wall, heart pounding, until he had left the room.

**

He was right, it was the longest evening of her life. She spent most of it the kitchen table doing some work on her laptop, to give herself something else to think about and because it let her hide her nervous anticipation from both brothers. 

Lying in bed waiting for her husband to fall asleep was even worse. She waited as long as she could stand to after she was sure he had finally dropped off before getting out of bed as carefully and as quietly as she could to make her rendezvous with Loki in the spare room.

She let herself in without knocking; he was expecting her arrival, there was no need to announce it.

He was wide awake waiting for her, lying on his side facing the bedroom door. He lifted the covers to repeat the previous night's invitation and she knew before she joined him that he would already be naked - why waste time dressing for bed when he knew she would be with him before long? 

She was right, and before long her own nightclothes were gone as well, tossed to the side of the bed with extremely indecent haste. 

This time was more deliberate, having been arranged ahead of time with them both knowing that sex was inevitable that night. They might even have spent some time exploring each other if they weren't being hurried by the need for her to return to her own bed before her absence was noticed. 

She was less passive this time too, having passed the point where she could lie to herself about her own role in making this happen. She wrapped her arms around his neck and her legs around his waist, moaning each with each thrust of his hips.  

“Quietly,” he whispered, his breath hot on her skin. “We don't want your husband hearing how much you're enjoying yourself.” 

That mental image should have filled her with guilt and made the whole thing unappealing, but it only increased her arousal, making her want it even more. The betrayal and the danger of it were not flaws but enticements. They were the whole reason she was in the wrong bed with the wrong man, edging ever closer to sexual ecstasy. 

She was not alone in this; Loki pushed himself higher over her, arms straight and palms planted on the pillow to either side of her head, and the new position gave him more leverage to fuck her deeper and harder. Despite the warning to keep quiet her moans became louder, urging her lover on even more. 

“You can't scream, Jane, no matter how good it is.” His eyes closed, pleasure obvious on his face. “Fuck… he doesn't deserve you… He'll never give you what you need.”

Her legs tightened around his waist, keeping him close as she started to come, and she cried out exactly as she shouldn't. The sound made then both freeze, and Loki clamped a hand over mouth, resisting her attempts to make him move it until he was satisfied that they hadn't been heard. 

After a few more hurried, almost thoughtless thrusts he came too, and lay on her breathing heavily, cock still inside her until she worried he was falling asleep and pushed at his chest until he moved off her.

“We have to stop doing this,“ she said. 

But that was why it was so good. She was jeopardising her marriage and the risk of being caught could only increase with each quick coupling no matter how quiet she was during them. It was exciting because she should not be doing it. 

Which was why she knew she wouldn't be able to stop.

Chapter Text

Jane wasn't going to visit the spare room tonight. She had no need, Thor had more than satisfied her already and she would soon be asleep at his side, relieved of any risk of temptation. 

He always fell asleep without much trouble, especially after sex, so Jane was used to being awake on her own for a while until her own body accepted the need for sleep. Lately this had given her too many opportunities to betray her husband, but tonight wasn't going to be one of them: it was late, the house was silent, and she had already come.

She left the bed to head to the bathroom. There was light in the hallway from the open door of the spare room and as she stepped through that pool of light Loki grabbed her by the arm and pulled her inside, closing the door before she had a chance to protest. 

She shook her head, turning to leave. “Not tonight.” She did not rule out another night. 

Loki moved faster, stepping forwards to back her up against the wall. 

“I heard you,” he said, voice low in volume and pitch. “I heard you moaning for him. I heard him fucking you.”

For the first time she realised how much of his motivation for this affair was envy – a general envy of his older brother that had very little to do with her or any quality she possessed. It should have been off-putting to be a weapon used against someone she loved, and she didn't like it, but she didn't not like it enough . She had become addicted to the thrill of hurried, secretive, sex and didn't want to give it up for anyone: not for Thor’s sake, and not for Loki's either.

His hand pushed into her shorts, fingers pressing roughly into her. She protested with a stifled cry and a warning hand to his chest, but he had already found what he wanted: he held up wet fingers, sticky with his brother's come, and stared at her in silence.

She felt the need to defend herself even though she had done nothing wrong. “He's my husband,” was her needless reminder. “You can't be upset that I have sex with my own husband.”

“I'm not,” he said, not convincing her at all. He touched her lips with his come-coated fingers and pressed until she took them into her mouth, licking at them while her eyes stayed locked with his. 

His breath caught, eyes widening like he was shocked she had actually done that, and then he pulled his hand away and kissed her, deep and eager, tongue against hers.

Could he taste it? 

She grabbed at him, wanting more, and he pushed her shorts down her legs without her making any attempt to stop him. “I want you to have mine in you too,” he said, half-whispering the words, mouth against her ear and breath hot on her skin, sending another shot of desire straight to her core.

He freed his cock and then with a firm grip on her waist he lifted her up against the wall, sliding in all at once with her legs wrapped tight around him. She gasped and closed her eyes, comparing the size and the shape of him to the man she had just been with, biting down on her lip to bite back a moan. She was becoming sick and depraved, she felt, but that idea just made her slicker and more responsive to the push and slide of his cock in her. Her cunt was still a little oversensitive so soon after her last round of sex, and it seemed to her that she could feel every difference between one man and the next, like could have mapped out every detail just by comparing the feel of them inside her.

“Look at me,” he said. It was half plea and half demand and she opened her eyes again, clutching at his shoulders, holding on while he held her thighs and slid and shoved and filled her over and over. She ground against him, seeking more pressure on her clit to bring her to her end, gasping each time she found it.

Adultery aside this was still a bad idea - she was feeding an unhealthy rivalry and letting him use her as a weapon against the man she loved and lived with. She must be wicked to enjoy it so much, to be getting off on something so twisted, but she was too far gone to care about that. 

They were always quick; they had to hurry to finish without getting caught but also that threat itself made the act more exciting, too arousing to resist or to hold back once they had given in. It was almost embarrassing how little it took to make her come during these secret encounters, but they didn't have time to take things slowly anyway, nor did they want to. 

She was so close already, biting back moans and trying to silence her desperate whimpering sounds. 

Her fingers dug sharply into his shoulders when she came, and with her other hand she tugged him to her by his hair, muffling her final sounds in a kiss, groaning again when he came as well, filling her for the second time tonight. It was all too good and too much; the second time was so much better for reminding her of the first and for the thought of the two men's releases mixing together inside her.

She wasn't expecting the soft kiss that followed. It was slow, almost tender, though she was still balanced against the wall and he was still inside her. She licked her lips after it, uncertain. 

When she was back on her feet Loki knelt to help her back into the thin cotton shorts she had arrived in. He kissed the skin just above the waistband before standing again. 

“I'll miss this when I move out,” he said. 

A cynical retort that of course he'd miss what was turning into almost nightly sex died on her tongue when she realised that she would too. Jane has been telling herself that when the temptation went away everything would go back to normal but now she wondered if it really would. She would still see him often even if it became a lot more inconvenient to act on her baser impulses with him, and if she couldn't do that then she really was going to miss it. 

“It's better that way,’ she said, more to convince herself than him. “And this is better because it isn't going to last. It's like having a romance on vacation.”

“Romance?”

She felt herself blush. “Or whatever. You know what I mean.” 

“Maybe.” He bent to kiss her cheek, again softly enough to unsettle her. “Get back to bed, Mrs Odinson.” 

That was the appeal of this, of course, for both of them - she was Mrs Odinson, who shouldn't be available to anyone but Mr Odinson. Especially if that someone else was another Mr Odinson.

Chapter Text

“How's the headache?” If it didn't start fading soon she was going to insist they went home; a nightclub seemed like the worst possible place to stay with a headache.

“It's not great,” admitted Thor. Guessing Jane's intention, he said, “I don't want to ruin our night out.”

“None of us is going to enjoy it if you're in pain!” 

Loki spoke up; “Go home, Thor, get some rest. I'll look after Jane.” This he said innocently enough but as he spoke his hand moved down her back, ending with a squeeze of her ass that made it clear what he intended ‘look after’ to mean. It sent a nervous thrill to her stomach and made her impatient for Thor to take his advice and leave. 

She hated the person she was turning into, but the process was too addictive, too damn enjoyable. She was too weak to ignore the touches hidden by the low lighting of the club, and the promises they seemed to make.

“You could have gone with him,” said Loki when his brother had been herded into a taxi. “Or are you enjoying yourself too much to play the loyal little wife?” 

“I'm not being disloyal,” she pointed out, partly to provoke a response.

“Not yet,” he agreed. “Come on.” He took her hand and led her back to the dance floor, pulling her close as soon as there was enough room to stop and take up some space.

She put her hands on his shoulders without any prompting and he drew her closer still, his hands heavy at her waist. Too close, and his grip wasn't going to let her try to correct that even if she had wanted to.

“We haven't danced since your wedding, have we?” he asked, with a wicked smile. He turned her around, pressing against her back, an arm around her waist. “Different kind of dancing there.” He spoke into her ear, free hand pushing her hair out of the way. “Not as much fun.” 

He ran that hand down her arm, fingertips leaving goosebumps in their wake, and gave a gentle bite to her earlobe. The arm at her waist tugged her closer; he was hard, his cock an unignorable pressure against her ass even through a few layers of clothing. On her thighs she felt his long, teasing fingers playing with the hem of her dress, reminding her how close she was to being even closer to him. 

She decided to take full advantage of being alone together and to get ‘looked after’ before she had to go home. “Can we go somewhere?” she asked, with no idea where they might end up, which was a source of excitement by itself.

There was no answer in words, but he took her hand again and led her away from the crowd, through a door and down a hallway, and then another door opened to the outside air. It was a narrow alleyway, silent at one end but with cars flashing past at the other. She had no idea how much risk there was of being caught out here, but it felt dangerous enough for her to let Loki push her against one of the red brick walls and kiss her, one hand under her skirt, dragging it up to over her hips and the other dipping between her legs.

He found her wet of course, two fingers slipping into her easily, making them both gasp, the anticipation already almost too much to bear. She twisted around, turning to put her hands on the wall. 

“This way,” she said, answered only by the metallic sound of his belt buckle. She moved her feet further apart and bit her lip as he pulled her underwear down, cold air hitting her bare skin before a hand settled on her hip and held her there, and then she closed her eyes and moaned softly as his cock slid slowly into her heat.

He kissed her shoulder then pulled out almost completely before slamming back in, harder than she had expected and so good that she cried out, the sound echoing down the alley.

“Shh… Don't want to get caught, do we?” He breathed the words against her ear, holding her hips tightly, fingers digging into her flesh. Another kiss, this one on the side of her neck. “Don't want anyone finding out what you've been getting up to.”

It hadn't only been her, but she liked the idea too much to protest. She pushed back against him. “Don't stop.”

“Wasn't going to.” 

With the excitement of conducting their betrayal outside, where they could easily be interrupted, it wasn't long before she was at the precipice, tense with arousal, and she braced against the wall when her climax hit her, legs shaking beneath her, Loki's laboured breathing in her ear as he followed her. 

There was no opportunity to linger, for doing so would only increase the odds of discovery. They put themselves back together, exchanging only a few words before they reentered the club.

Back inside Loki guided her towards the bar.

“Let's have another drink before I take you home.”

To Jane, it was an obviously bad idea but she followed anyway, hoping she didn't look too guilty or too dishevelled from the alleyway encounter.

“If someone knows that we -”

“Jane, relax.” He tucked a lock of her loose hair behind her ear and then took her hand, moving close. “Nobody knows you're not here with me.” To back this up he kissed her, open mouthed and passionate, and then watched as she took nervous glances around the room. 

He was right, nobody was staring.

“They don't know you're not mine.”

“I'm not -” Her words were cut off by another kiss. She had just fucked him in an alleyway, he had some claim over her even it was only that of an addiction she was bad at resisting. 

He had a possessive arm around her waist when he ordered their drinks, holding her close and acting like her date for the night. 

He was showing off and enjoying it, but worse than that she enjoyed it as well.

**

The house was dark and quiet when they arrived, and they stood in silence at first, listening for any sign that Thor was up and about. When they heard nothing, Loki grinned and kissed Jane lightly. 

Even sure they were the only people awake in the house, she pulled away. 

He touched her cheek, cupping her face in a hand and running his thumb across her lips. “Suddenly shy?” He pressed the digit into her mouth and she met his gaze without flinching, licking the pad of his thumb before she moved his hand away with one of hers.

“Not shy, just not stupid.” It sounded good, but they both knew she had been reckless before and would be again if she got wound up enough. 

She made her way up the stairs with him a step or two behind her and they parted in the hallway, silently heading to their very separate beds. 

Chapter Text

It would be over soon, Jane told herself; two days from now Loki would move back to his own home and she and Thor would have this place to themselves again, and with this return to normal living arrangements everything else would go back to normal as well.

So she told herself, yet again, as she waited restlessly for the privacy she needed to be able to betray her husband once more. She had lost track of how many times she had done this already, but it was ending soon in any case. She would not do it again after Loki went home. She wouldn't get a chance to do it anyway, and she was glad that she wouldn't. If she took full advantage of the opportunity while she had it, then that hardly mattered; in a few days she would be faithful again, and contentedly so.

As soon as Thor was out the door and off on his errand, Loki stood from the couch and held a hand out to Jane.

“Upstairs?” he asked. He was confident that she would say yes and Jane could hardly complain about that when he had every reason to be. She so rarely turned him down when he asked for her.

She expected him to take her to the spare room, the place that had become their illicit love nest, but he passed that doorway and moved on until he was leading her into her own bedroom, to her own bed.

Of course, it was also Thor's bed. That would be why Loki wanted to do it here, so that Thor would have to sleep where his brother had fucked his wife. It was a cruel idea from a twisted mind and just the thought of it sent heat pulsing through her. Jane was the prize in this game that her husband didn't know he was playing, the means by which Loki could take revenge for years of imagined slights. She knew there was a one sided rivalry here that she shouldn't feed, but she had her own weaknesses.

She liked doing something wrong. She liked being at the centre of someone's attention for such a bad reason. She kissed her brother-in-law as eagerly as he kissed her and she almost trembled with the thrill of it. They might be caught. She might be making the worst mistake of her life, throwing away one man's love for the jealous touch of another. She loved it.

Once they were on that bed he pushed her thighs wide and kissed the inside of one before turning his attention to the other. They didn't have time for teasing but she let him do it anyway, and he moved on eventually, sliding a finger into her and tonguing her clit. He added another finger when she pushed herself against him, and suckled at the nub until she was writhing and gasping then climaxing for him.

She fell limp against the sheets and he moved up, pulling her knees up to spread her wider and sliding into her soaked cunt with a low groan.

He started moving at once, quicker than before, going deeper with each thrust, shaking her and the bed beneath them. It was the bed that made it different this time and drove his lust and his need.

She dug her fingernails into his back, leaving scratches, her legs high and wide.

He asked her, breathing hard, “Do you think of me when you're with him?”

She didn't answer. She didn't want to.

He spoke again, closer to her ear; “Tell me,” he demanded.

“Sometimes,” she admitted, and the effect was immediate.

He moved faster, fucked her with short, hard thrusts, coming quickly now that she had told him what he wanted to hear. He sighed against her skin, kissing her shoulders and her neck as his cock softened, still inside her.

Jane had been telling herself that none of this mattered because it would end when Loki moved out. There was a time limit to her adultery, an inevitable end point in the very near future beyond which she wouldn't continue. It was a good excuse and she was about to lose it if she didn't end this affair on schedule; that really would, to her mind, actually make it an affair and something she was fully responsible for indulging in.

When he moved off her, she said, “You know that was the last time, right? This ends when you go home.”

“Of course I know that,” he answered, relaxing on her marital bed. “Is it me that you're reminding or yourself?”

“You're not that good.” It was easier to be annoyed at his egotism than to reproach herself for having thought about not stopping - about how they could find excuses to meet up and where they could go to be alone together.

“You won't miss it much then,” he replied, getting up from the bed. He began to dress and she made a point of not replying to his statement in case her response was not the one it should be.

Instead she said, “I'll have to change the sheets.” The state of the bed by itself might be enough to give them away; she had been taking care of the stained laundry from the spare room herself to make sure Thor didn't think of any awkward questions about what had happened to them.

“Don't,” said Loki.

She stared at him. “You want us to get caught, don't you? So that Thor knows what you did.”

“I don't, I just… I like the idea,” he admitted, “but I don't want it to actually happen. He'd never forgive me. Not for this.”

“He might.” She wasn't sure of that, but she felt sure that of the two of them it was his brother that Thor would find it hardest to stay angry with - what was a few years to a lifetime?

“If it had happened once, maybe, but it's happened a lot more than once.”

“So why did you keep doing it?” She was afraid of what his answer might be, but it was edged with excitement too. She wanted to know his motive here, whatever it was.

He cupped her cheek with his palm. “Because I'm not a good person. And neither are you.”

She didn’t try to protest against that judgement, or to reject the kiss that came with it.

Chapter Text

As she stripped the bed in the spare room, now unoccupied for the foreseeable future, Jane's mind offered up memories of all the betrayals she had recently committed in it, often while she was supposed to be asleep beside her husband in the adjoining room.

She remembered slipping between the sheets to join her brother-in-law beneath them, ending up beneath him not long after that, trying not to make enough noise to give away what they were up to, and how good those secret meetings had been. She felt herself heating as the memories replayed, arousal building until she abandoned her task and went in search of her husband to take care of a now unignorable need.

It didn't matter that she was thinking of his brother when she came, as long as Thor never found out and as long as she kept up her efforts to forget the long weeks she had spent indulging in adultery.

**

It surprised her how empty the house felt reduced back to only two occupants. It was suddenly too quiet but she hoped this would help calm her back to rationality now that the source of her temptation was no longer continually present to remind her of it. Now she could free herself from it simply from a lack of opportunity to indulge, dropping a bad habit through enforced abstinence.

The fact that she still thought of Loki in the same terms as an addiction seemed like proof in itself that she needed to get over whatever strange spell he had somehow put her under, to make a change she would stick to rather than getting caught up in the dangerous pattern of returning for another dose of excitement that she didn’t really need.

Jane was strong-willed, she could do this as long as she didn’t let herself give in ever again.

**

She was in the kitchen when the first text arrived, pulling her phone from the pocket of her jeans expecting some mundane and innocent message from a friend.

What are you wearing?

She rolled her eyes at the cliche even as excitement stirred in her stomach and her pulse quickened.

She shouldn't answer, it would only encourage him, and if she did reply she should ignore the question and change the subject.

Her thumb flew over the keyboard on the screen.

Why does it matter?

She waited, lip between her teeth, for his response, hoping he would see sense and behave himself and wishing that he wouldn't.

It would make the fantasy more realistic.

Her own mind offered up a fantasy as well, of him in bed with his phone in one hand and his cock in the other. Despite it, she texted back some resistance.

I can't play this game anymore.

It was a while before the reply arrived, almost long enough for her to talk herself into ignoring the next alert from her phone on the assumption that it would be him.

Almost long enough, but not quite.

Call me if you get some time to yourself this evening.

Distance had not had the effect she had assumed it would and already she was hurtling back towards the kind of lust-fuelled impulsive decisions that had led her into what she could no longer really think of as anything but ‘an affair’ – it was starting to feel inevitable at this point, something she couldn’t break out of, a fall dictated solely by the laws of attraction. Lust it may have been but that was still attraction and in this case it seemed to be one that was impossible to resist.

She replied to his text with a simple Okay.

**

She made the call from her bedroom, fitted into a narrow window of time that she hoped would be long enough for whatever discussion Loki had in mind, though she strongly suspected that the reality would not be anything that could be described in such innocent terms.

He answered the call before the line had rung twice.

“Are you alone?”

“Yes.” She held her phone tightly, made herself breathe normally; she had started breathing faster as soon as she heard his voice, ready for some wicked suggestion.

There was no delay. “When's the last time you came?”

“A couple of nights ago, maybe.” She knew exactly when it was, she just didn't want him to know that she knew.

“Oh, you really are suffering without me, aren't you?” He said like one of his jokes but she could hear the heavier breaths and the huskiness that crept into his voice. “Touch yourself.”

She moved her free hand downwards as soon as he said the words, slipping a hand into her underwear, letting him hear her gasp when her fingers brushed against her clit.

“Are you in bed?” he asked.

“Mm-hmm.” She circled her clit as he spoke, unwilling to stop now that she had started.

“Me too.”

“Are you jerking off?” She knew he was, she could hear a rhythm in his breathing that she recognised from when he was inside her almost ready to come.

“Of course.” He moaned quietly. “I can't stop thinking about you, about how good you feel.”

She was getting close, her hand moving faster, angling her pelvis to circle her entrance with a fingertip while her thumb rubbed over her clit.

“Please…” She wasn't sure what she was asking for, but whatever it was she knew he would provide it.

“Come for me, Jane, like you did when we were together, when I was inside you.”

She came with a cry she didn't try to hold back and heard him do the same at almost the same moment.

Neither of them spoke right away, just listened to themselves calming down again.

Loki broke the heady silence first. “Ughh, what a fucking mess. Jesus.”

Jane laughed and he continued. “Cleaning this up with a tissue feels like a waste, it should be inside you, or on you, at least.”

He always took everything too far, but so did she now and whatever influence he had had on this she was sure it must have built on something already within her, dragging it into the light but not creating it from nothing.

“I don't feel guilty,” she blurted out, letting go of that at last. This was it, this was the deepest cause of her anxiety. “I'm just annoyed that we can't sneak off together and… you know.”

Loki supplied the word for her: “Fuck.”

“Yes,” she admitted. “It isn't even about you, it's just… I don't know.”

“You miss being bad.”

“Which is horrible and unhealthy and I need to…”

He interrupted her: “Why don't you come round when Thor's away this weekend?” he suggested. “You could stay the night.” He said those last words in the coaxing seductive voice that had worked too well on her before. She knew better than to listen to that voice.

“Friday,” she said. “I'll pick up a few things from here after work and then I'll be at your place.” It wasn't the smart thing to do but it was what she wanted to do.

“I'll see you on Friday then.”

“Right.” She didn't say more, too distracted by the new rush of arousal from having arranged to continue the affair and with thoughts of what they could do with a whole night together. They had always rushed to finish before they could get caught in the same bed or hidden behind a closed door or on that one even more reckless occasion fucking in an alleyway, just outside a crowded club.

She had been silent for too long and Loki spoke again: “You're turned on again now, aren't you?” She didn't have to answer that question before he laughed quietly, without mockery. “Thor can sort you out for now, I'll take care of you at the weekend. Wear something nice for me.”

With that he hung up and Jane was left alone with only her conscience again, but unfortunately it seemed to have checked out, at least on this topic.

She started trying to decide what ‘nice’ thing she should wear to make the weekend a little spicier.
