Double Penetration - M/M/F

"You're both sure about this?" Natasha supposed she shouldn't have been as surprised about Thor asking as she was, but she couldn't help but smile. It was kind of cute in its own way, she supposed, but she was looking to Loki at the moment. There was some trick up his sleeve, something that was making him grin as if he'd won the damn lottery.

"It is Natasha who requested this," Loki said. "And as she trusts me I trust her to know whether or not this is what she'll want." From his pants pocket he pulled a small vial, a clear liquid tipping to the side as he offered it to her. "This is handcrafted by Amora, and I have its antidote as well if you decide at any time this is not what you want. It will make you lose all inhibitions, all cares of the world, allowing you to focus entirely on desire. This is what you want, Natasha?"

Her eyes widened as she took it from his hands, uncapping it and passing it just under her nostrils. It didn't have a smell to it, and she was sure that it didn't have a taste, either. He could've slipped it into her drink at any time, hell could've thrown it down her mouth in a second and she wouldn't have been any the wiser, or any more able to stop it than she could break out of his grip when he meant it. The fact that he didn't, that he'd presented it to her and given her the choice? She replaced the cap on the vial, smiling.

Quicker than he'd expected she leaned up and kissed him hard on the lips, clasping the vial tightly in her hand as she wrapped the other arm around his neck. "Yes. Please," she murmured against his lips.

"Thor, I'm sure you're curious why you're here as well." Loki said after he'd grinned and assured Nat that everything was going to be fine. His brother, who'd been caught somewhere between a smile that clearly showed how happy he was for his brother and how uncomfortable he was being there as they decided to be adorable, nodded in appreciation. "Amora warned me that this dose turned out to be rather strong, and rather than tempt fate and have its effects last too long, and run the risk of, well, fucking Natasha to death, I'd rather give her as much pleasure as you and I can give her in one go. Is that agreeable?"

Hell, Nat was wet just thinking about it, unable to stop herself from smiling as she nodded quickly. Oh yeah. She was very much okay with that. Thor, too, nodded. Now that he knew what was happening he didn't seem to be as nervous, and for that she was grateful. Nothing worse than an unsure partner, especially when Nat needed to trust them both to know how to best handle her. She had no idea how this drug or whatever was going to work on her, and though that should've terrified her, the antidote being so close by, and in Loki's possession, calmed her nerves very quickly. Despite all his claims of the contrary, Loki must've trusted Thor more than he let on, too, to have asked him to join the pair. Thor's brain seemed to be on the same wave length, and he stood to briefly embrace his brother before releasing him and looking back to Natasha. Something on his face shifted, as though he could hardly believe his luck at the woman sitting just in front of him. Nat smiled broadly and looked back at the vial in her fingers. With sure, steady fingers she undid the cap for a second time that night and looked up at the two gentlemen. "Bottoms up," she murmured, and downed the contents in a single gulp.

She smiled briefly up at them before she felt the world suddenly shift. Grow hotter. Oh, God. Every fiber of her clothing felt too heavy, weighing down on her skin and pressing in all the wrong places, shifting uncomfortably atop her. Her lips parted in a low whine as she started to remove her clothing before either of the other men had a chance to do anything, laying back to arch her back and raise her hips so she could shove off her jean shorts. Her panties went with it, and not half a minute later her shirt joined. She hadn't bothered with a bra, not on her day off when she was just going for comfort. It didn't matter, now. Her hands fell on her own breasts as she looked up at Loki and Thor with heavily lidded eyes.

"Thats-incredible," she could barely get the words out from her mouth, tongue tripping over them as she bit back a moan, fingers pinching her nipples hard. Loki was already grinning, while Thor looked on with a mix of what might be intrigue and arousal from the noises making their way from Nat's lips, the way her hips undulated without even being touched and the scent of her arousal painting the air. It was enough to make Loki's mouth water, and he wasted no time in bringing his lips to hers, kissing her hard, going between sucking on her bottom lip and exploring every inch of her mouth. She whimpered below him, hips rocking upwards. Thor took that as an open invitation and brought his palm trailing down her torso before fitting perfectly between her thighs. Pressing his thumb to her clit he started rubbing in slow circles. Nat pulled away from Loki with a wet pop and gaped down at Thor, hardly able to breathe, though she did manage for him to go harder. "Please, Thor. I need it," she begged and whined, pushing her hips up and into his touch to grant herself more friction, a satisfied moan rolling out of her mouth when he complied. Loki took her distraction as a chance to start undressing, and the minute his cock popped out of its confines Nat gave a quiet mewl of approval, wriggling out from under Thor to stand on all fours and swallow the dark-haired god down without coming close to gagging. Loki gasped, stars flashing behind his eyes as she worked her way up and down his cock, rolling her tongue around the tip, then the shaft. Behind her, Thor laid down and pulled her hips on top of his face, tongue making a long stripe up her pussy so that her whole body vibrated with moans. She telegraphed his movements onto Loki's dick, sucking and giving as good as she was getting from his brother. His hand carded through her hair, holding her tightly as he started thrusting his hips in time to her own movements.

"Hold still," he growled to Natasha, voice tinged with affection as she responded, loosening her jaw completely. He gave a few shallow thrusts into her mouth, making sure she wouldn't choke, before thrusting in in earnest. She moaned from around him, taking it until she wasn't sure how her jaw was still hanging on, and still it wasn't enough. Even with Thor beneath her, she needed more. Her body quivered with her first orgasm, one of many she was hoping, and only after Loki had done the same, his warm come squirting down her throat and into her belly, did he pull away. Not for the first time was she thrilled as his lack of a long refractory period, and as he palmed his cock back to life Nat looked over at Thor.

"Why-are you still wearing-pants?" She gasped, barely able to form words as she pulled away from his mouth on her cunt to mess with the button and zipper on his jeans. Commando. She liked it. Pushing down his jeans she sank herself, still wet with his saliva and her own arousal, onto his thick cock without so much as a problem. Oh. So much better. With her back to him she rode him as hard as she could muster, pulling herself up and down on his length until her thighs burned and he moved his hands to take control of her hips. She couldn't have been happier, back arching and hands flying to her breasts as Thor sat up and bit down on the junction between her neck and shoulders. Somewhere behind them there was movement and Thor pulled away from her, hands taking her once more by the hips and raising her up and off his cock. There was hardly time for her to whine when he turned her to face him and brought her right back down, impaling her hard enough to knock most of her bones out of alignment she was sure. A scream ripped through her throat as she came around him, tightening up like a vice as she fucked herself on his cock even harder than before. He groaned and met her thrust for thrust, hands fisting in the bedding to keep from bruising her too bad. In the back of her mind his consideration registered, but there wasn't time to think more about it. She needed more. A warm, wet finger pressed itself to her other opening, working its way past her so that she whimpered and looked back. Loki was grinning down at her and took her lips with his own.

"By the nine you taste so sweet," he whispered against her, adding a second lubed up finger and spreading them as far and wide as he could so she whimpered and quaked.

"More. Please, I need more," she begged, even after he'd worked a third, then fourth finger into her ass, stretching her as far as he could.

"Alright then my girl, you'll get it," he promised. He'd barely removed his fingers from within her before his cock took its place, thick and hard and so hot she thought she'd burst from the feeling of being filled. Beneath her Thor stilled, groaning as he felt his adopted brother slide into Natasha's ass, and though the pair might've liked to take a breather Nat wasn't interested in breaks. Not at all. Not wanting to waste any of the beautiful stretch and burn she felt, she quickly jolted her hips back towards Loki, taking Thor at just the right angle so the head of his cock battered against her g-spot, and Loki was shoved even further into her. Voice hoarse from all the screaming, she kept that up until Loki had her by the arms, holding her still so he and his brother could take over. Use her. Thrust into her over and over until she thought her senses would overload, and all she could do was stay there and take it, brain too overcome with sensation and pleasure and just yesyesyesyesmore. She lost track of how many times she'd come around them, both of their mouths taking it in turn to swallow her cries for more before biting, licking, and sucking their way up her throat, shoulders, collar, and breasts. At one point Loki duplicated himself, and Nat let the clone fuck into her mouth much as the original had done not long before that so she felt completely, and wholly, stuffed. It was perfect.

Intense wasn't a strong enough word to describe her final orgasm, her body almost entirely numb from being so fucked out and exhausted, but still with enough strength for her to pull away from the clone and reach back to kiss Loki hard on the lips, hot come from the third cock spurting and painting her breasts as she shook hard enough to register on the Richter scale, before going completely, blissfully limp. Beneath her Thor rode out her orgasm before finally coming to his own, and Loki, who hadn't been holding back as his brother had been, followed suit. The warm liquid oozed out of her, giving her goosebumps and making her shiver, before she was lifted off of the blond man and laid gently down in bed, the clone disappearing from its spot. Light kisses feathered their way up her calf, knee, upper thigh as she was dabbed clean and wrapped in a light blanket. The heat finally had burned its way through her whole body, leaving her exhausted and grinning from ear to ear as Loki came to lay on his side in front of her, one arm casually wrapped around her waist. Thor repeated the gesture, though on her other side, kissing from the base of her neck to the soft point between her shoulder blades. Loki's lips found hers, swollen and chapped and fitting perfectly against her own. It didn't take much after that for her to pass out, at ease with the world for the first time in what felt like years.
