Thinking about Fandral being so loyal to Thor that he doesn't protest when Thor wants to fuck him, even though it's something he doesn't want to do at all.
After all, Thor is the prince, and he's sworn to serve him, whether it's at his side on a battlefield or in his bed like a common whore.
Loki didn't respond, too focused on trying to push up the front of Thor's shirt, fingers blindly brushing over his skin. He knew that Thor was right; huddled in the back of a weapons room hardly made a secure hiding place. At any moment, a training warrior could walk in to switch out his weapon or polish his blade, only to catch the two brothers in a damning position.
But Loki didn't care. He knew what he wanted; and he wanted it now. He didn't want to be kept waiting, and it wasn't as though Thor had put up much of a fight when he dragged him back here.
At last, the fabric was bundled up, and beneath, Thor's ample chest, now even more impressive after what Loki had done to him. His nipples, already perky and red, were starting to leak in response to his touch.
Loki squeezed and groped, unable to fight the grin that started to form on his face, and Thor yelped, grabbing at his hands, forcing him to slow down.
Thor enjoyed it, too, Loki knew, even if he acted like he didn't. He had already made him come multiple times without even the slightest touch to his cock.
"We'll be quick." Loki assured him, moving in to steal a lazy kiss from Thor, which he returned, furthering Loki's certainty that he wanted this.
Thor just nodded, looking at him with eyes clouded over with want, even moving in to hold his shirt up for Loki. And Loki grinned, shooting him a wink before he pressed his lips just beside one of Thor's nipples.
"Just get it over with." Thor shut his eyes, his face heating up. Loki's hand wandered down to Thor's crotch, and was pleased to find him already straining and hard in his trousers.
He would have traded him for longer, but since they were rather pressed for time, Loki relented; his lips closed around one of Thor's nipples, tongue flicking over the tender nub. He was rewarded with a low, barely-restrained moan from Thor; a sound Loki could never get tired of. He sucked gently, and was rewarded with a mouthful of milk. It was slightly sweet, pleasantly warm and comforting. Despite being in such a risky position, Loki instantly felt relaxed, letting his eyelids shut halfway as he suckled lazily at Thor's breast, the taste of his milk and the sounds of his pretty moaning were the only things that seemed to matter.
He was so out of it that he didn't hear the sound of footsteps approaching, and the only thing that snapped him out of his milk-induced haze was Thor gasping and forcibly trying to yank him off as the door open.
It was too late, though. Loki broke off and glanced over his shoulder, body going tense and rigid, before his eyes settled on their intruder.
"Fandral." Loki breathed out, and there was relief in his tone. Relief that it hadn't been a guard or another warrior. Someone who was less of a degenerate than the man who looked upon the scene in surprise, and then quickly closed the door behind him.
"What—get out!" Thor snapped, pushing Loki further away when it became clear that Fandral wasn't leaving. Loki looked at him curiously.
"And miss out on whatever it is that's happening in here? I'm afraid not, my friend." Fandral said cheekily, pushing a box in front of the door before moving closer to the pair. He was a bit of a mess; clearly having just gotten off the arena, but still no less as charming as always.
Loki smirked over at him, relaxing once again. "You're in for a treat, then."
Thor looked between the two of them in shock. Betrayal clearly stung in his voice when he addressed Loki; "No. No, I knew this was a bad idea, brother." He started to push his shirt back down as Fandral looked upon his body lecherously.
"Oh come now, don't be greedy. Fandral is our friend, is he not?" Loki asked, gripping the hem of Thor's shirt to prevent him from pushing it down.
"I'm not in the habit of performing sex acts with friends." Thor said.
"Interesting. But you'll do them with your brother?" Fandral asked.
"Shut up, Fandral." Loki said. "And it's hardly a sex act, however much you get off on it. It's intimate, but nothing more, really."
A lie. They both could get off on it. And there wasn't a doubt in Loki's mind that Fandral would as well.
Thor started to protest some more, but Loki reached over, squeezing one of his nipples hard enough to make Thor yelp. A thin stream of milk sprayed out, landing on the floor, wasted.
Fandral watched, a mix of intrigue and confusion on his face. "Is... Is that...?" He stammered, pointing over to the droplets on the floor.
"Yes." Loki drawled, his fingers still clasping Thor's nipple between them, though he didn't squeeze again.
Fandral moved closer, glancing curiously at Thor's chest. He reached over, grazing his fingers over the firm, swollen flesh, looking back up at his friend to make sure he wasn't opposed. And Thor, though he was trying to put on the act that he didn't want it, practically melted at being touched by the both of them, shivering as his eyes fell shut.
"Go on and have a taste, my friend." Loki said, giving Fandral a playful shove.
Fandral smiled, flicking his thumb teasingly over Thor's nipple, causing the crown prince to moan loudly, pressing up against the wall.
"As generous of an offer that is, my dear, I'll have to pass." He said, though he did not tear his eyes away from Thor's chest.
Loki looked at him in surprise. It was not like Fandral to turn down such an offer. "Why?"
Fandral laughed softly, seeming to know his reason was a bit ridiculous. "I don't care much for milk, I'm afraid."
"Oh, but you haven't tried Thor's. It's not like any other kind." Loki insisted.
"I've tried many kinds. I've liked none of them." Fandral said adamantly, beginning to sound a bit like a child who refused to eat their dinner. He leaned in, pressing a kiss to Thor's neck while he still idly played with his nipple.
Thor tilted his head, exposing more of his neck to Fandral, shivering with pleasure as Fandral nipped at it. His eyes fell on Loki, who smiled, clearly enjoying what he saw.
"But don't let me stop you both." Fandral said softly, though he still kept close to Thor.
"Go on. If you don't mind me watching, of course."
They didn't.
Loki dipped his head, once again latching onto one of Thor's nipples, this time sucking hard, his teeth brushing over the tender flesh. Thor started to cry out, but Fandral moved in, catching his lips in a kiss, silencing him, save for a few muffled sounds that managed to slip out.
"Nine, Lo really turned you into his bitch, didn't he?" Fandral said lightly. "This is why you're always training with your shirt on, isn't it?"
Thor groaned, reaching over to grab onto one of Fandral's arms so he wouldn't pull away, his earlier hesitation seemingly having vanished.
"Can you come like this?" Fandral asked, pressing just a little harder down on Thor's nipple, so that milk beaded out of the tip, slowly starting to dribble down onto his fingers.
Thor gasped sharply, nodding, only to let out a "fuck." as Loki bit down further on his nipple.Loki pulled off, leaving Thor mewling in frustration, and, with a mouthful of milk, kissed Fandral.
And perhaps if the milk had come from anywhere else, this would have ended quite badly. However, the milk slipped on to Fandral's tongue as Loki swapped it to him, and when he had swallowed it down, it was clear that he wanted more, as though put under a spell.
Loki smiled knowingly, before turning back to Thor's tit, kneading the tender flesh.
"Loki..." Thor murmured, shifting to try and grind his arousal up against him, but Loki evaded him, latching on to his nipple once more, eyes falling shut as he drank down his milk.
Fandral moved closer, and Thor saw him, suddenly becoming desperate. He reached down, grabbing a fistful of his tit, a few droplets of milk forming at his nipple as he did so. "Please..." He begged.
Fandral didn't need any more convincing. He bent down, his lips closing over Thor's nipple, milk already flooding out before he had started to suck. His eyes widened briefly in surprise, having to pause to swallow down the warm, heavenly liquid. It was like nothing he had ever tasted. And it certainly didn't hold a candle to other milk he had drank in the past.
He suckled far more gently at Thor’s tit, clearly cautious about overstepping a boundary. Loki, on the other hand, just took what he already knew to be his, biting down hard enough to leave marks around Thor’s nipple, intent on draining him of all he was worth.
The contrast itself was enough to drive Thor mad, never mind the pleasure that the release of the milk gave him. His eyes rolled up, and he again started to jut his hips forward, desperate for a little more stimulation.
Loki would have been content to take his fill and leave Thor needy afterwards, but thankfully for Thor, Fandral was more generous. He shifted a thigh between Thor’s legs, letting him grind up against it as he lapped up the never-ending stream of milk.
Thor's moans grew louder, possibly loud enough to alert anyone near enough of what was happening inside, but the three of them couldn't bring themselves to care. He ground up against Fandral’s thigh faster, harder.
“I-I’m close.” He whispered, every suckle from the two men drinking from him pushing him closer and closer to the edge. Loki broke off of his tit, moving up close to Thor.
“Come for us, brother.” He whispered into his ear, kissing him roughly on the lips.
Thor could taste his own milk when Loki kissed him, and Fandral chose that moment to bite down harder on his nipple.
There was no hope for him to resist any longer, with a muffled cry, he came, his body seizing and then shaking as his orgasm crashed over him, his spend shooting into his trousers, a wet patch forming, though he couldn’t bring himself to care.
His knees felt weak, and if not for Fandral still supporting him, he would have collapsed down to his knees.
Fandral looked up, detaching from Thor’s tit, his nipple red and swollen and still dripping. He smiled, coming up to kiss Thor as well, and Thor submitted to it, his eyes falling shut.
“It’s our turn, brother.” Loki murmured, already starting to unbuckle Thor’s trousers. It always ended up like this. Loki drank his milk and then fucked him. This time would be no different, except that Fandral was there.
And Thor didn’t object, already having anticipated it. He would come again, and that was what mattered now. He didn’t care if anyone heard, or the looks they might get when they left.
Thor was bent over some storage crates, wincing as his sore tits were pressed against the flat surface, some milk leaking out onto it.
Loki got behind him, grinding his hardness up against his ass. Fandral came in front of him, his own tented erection just at eye level with him.
Thor blushed as Loki pulled his trousers down, smacking his ass harshly enough that the sound reverberated in the small room. He blushed even further as Fandral pulled out his cock, mouth already watering—something that Loki had already conditioned him to do upon seeing any cock.
He moaned as Loki pushed inside him, and Fandral took advantage of his open mouth, sliding his cock in past his lips. Thor’s eyes widened a touch. He had never taken two at once, and this quickly became overwhelming in the best way.
“I think you might have gotten me hooked, darling.” Fandral grunted as he started to fuck Thor’s mouth.
"Oh? I thought you didn’t like milk?” Loki asked innocently.
Fandral smiled, and leaned over closer. Thor moaned as more of his cock was shoved down his throat, though he clearly liked this, judging by how he was already hard again.
Loki met Fandral half-way, sheathing his length fully inside his brother as he kissed.
