Chapter Text
Steve’s head was spinning as he was slammed cheek-first against the wall. He laughed as Thor mouthed kisses at his neck and squeezed his ass. Steve could already tell his underwear was soaked with slick. He felt giddy, eager for more touch, moaning louder with no care to who might hear as Thor unzipped Steve’s pants and sank to his knees.
Asgardian liquor was no joke, Steve thought to himself in bemusement. He and Thor had been dancing around each other for years, ever since their first meeting in the woods. Steve had been immediately taken by the alpha, with his broad muscles and brash manner and summer rain scent. And he could tell that the attraction was mutual.
But while they worked well together as teammates, Steve had kept his distance romantically. He wanted mutual respect from everyone on his team, and he wanted to be trusted as a leader. Sleeping with any of them was a bad idea.
Even if Thor was everything Steve looked for in an alpha. Brash, determined, strong, but also kind and not dismissive of him as an independent omega. Peggy had been the same, and Steve had fallen for her quickly, too. This time around, he was determined to keep his feelings locked up inside. It was just easier, for a lot of reasons.
But it seemed that Asgardian liquor had other ideas.
Tony knew how to throw a party, and the party celebrating the recovery of the scepter was one for the books. Steve had enjoyed mingling with his friends and playing pool with Sam and Maria. But eventually Maria had splintered off to talk with her SHIELD friends, and Sam kept getting distracted by exchanging flirty looks with Natasha, who was lurking behind the bar. Steve was happy that his two best friends were mated, but it made him feel a little lonely, too. So he’d let Sam off the hook to be with his alpha, and Steve had been alone, until Thor had nodded him over and produced his flask.
And so here Steve was, finally giving in to his desires.
He moaned at the feel of Thor’s tongue between his cheeks, licking the sweet slick from his hole. He arched back into Thor’s touch, trying not to be too eager. Thor was talented with his tongue, rimming the edge of Steve’s hole, then thrusting deep. Steve hadn’t been with anyone since he’d gone into the ice. He’d forgotten how incredible it felt to be tended to by an alpha who knew what they were doing.
“Louder,” Thor murmured as he spread Steve’s cheeks wider. “I want to hear every moan. I love hearing all of your sounds, knowing that it is me who coaxes them from you, that you are desperate for me.”
It was easy to comply. They were in an empty study with the door locked, and there was plenty of revelry echoing down the hall to disguise their noise. And regardless, Steve was just tipsy enough to not care whether or not they could be heard.
“Please,” Steve whimpered. “Please, in me, now, please!”
“With pleasure,” Thor growled. In a matter of seconds he was on his feet and pressing his cock into Steve. His hands rested over Steve’s against the wall, and their fingers curled together.
“You’re intoxicating,” Thor rumbled against Steve’s neck as he thrust into him at a punishing pace. “The sweetest omega I’ve ever tasted, so tight and slick for me.”
Steve wanted to jab back that surely it was Thor’s flask that had caused the intoxication, but that buzz had worn off by now. And he felt the same way. His experience in the bedroom wasn’t vast, but he’d never been fucked like this by anyone before. Thor was so big, able to overpower him, or at least put up a decent fight, which was not something Steve had experienced since before the serum. He found it exciting.
And yet despite their frantic fucking, there were gentle touches, too. The way Thor clasped their hands, the sweet words he whispered into Steve’s ear and the soft kisses he placed along Steve’s neck. Steve easily let himself sink into the sensations and let Thor’s scent envelope him as he worked his way closer to orgasm.
“I want to knot you.”
Thor’s teeth gently grazed Steve’s collarbone. Steve gasped at the tingling sensation that ran over the surface of his skin. He could feel the beginnings of Thor’s knot pressing against his rim with every thrust, and it was very obviously large. He moaned again and felt a fresh flow of slick forming as his desperation for that knot grew wilder.
“Please, may I,” Thor asked again, breathless. “Say yes, and I swear to you…”
“Yes!” Steve interrupted. His voice sounded unfamiliar to his own ears, heavy with panting and desire. “Yes, please knot me, I want it, I need it, please!”
With a groan and a final thrust, Thor sheathed himself fully into Steve’s hole. Steve pressed his forehead against the wall and fought to muffle a scream as Thor’s knot swelled to full size, stretching him as his cock thickened inside Steve’s ass.
When Thor came, he did so with gritted teeth and his face buried in the crook of Steve’s neck. Every pulse inside Steve sent a little shock through his body, like an electrical current that set every one of his molecules on fire. He felt Thor’s come filling him, and Thor’s hands tightened around his own with more pressure than a regular mortal could withstand.
Steve realized with another muffled shout that he was coming as well, dribbling down the front of his thighs. His orgasm shook through his core, enhanced by the hum of heat in Thor’s touch.
Once spent, they stood silently, each of them steadying their breathing. Thor’s knot held his come inside Steve, and he kept giving slight thrusts, just a hint of friction against Steve’s rim to keep the pleasure of his fading orgasm alight. Thor nuzzled Steve’s neck and peppered his face and shoulder with soft kisses, whispering about what a sweet omega Steve was, how perfect he had been and how lovely he felt beneath Thor.
No one disturbed them. Steve gave a silent thanks that anyone who attended Tony’s parties would know better than to mess with a locked door. But as Thor’s knot deflated and reality sunk in, Steve began to stress. Before he could fully freak out, he looked down and got distracted, realizing that his come had gotten all over his pants.
“Shit,” he swore under his breath. He didn’t want to go back to the party with come-soaked pants. Regret began to sour the warmth of his afterglow.
Thor chuckled and kissed his cheek. “Do not fret. I’ll take care of you.”
He looked up at the ceiling. “JARVIS, please let me know when the hallway is clear so that I can get to my room.”
“It appears clear for now,” JARVIS replied with no judgement. “Mr Rhodes and Mr Stark are doing some sort of performance piece in the lounge that is proving quite distracting.”
Chuckling, Thor slid his softening cock from Steve, kissing his cheek again as he released. Steve tried not to whine in displeasure as the loss, or the come that immediately began dripping down his thighs.
“If only we had more time,” Thor said in a low voice. “I would clean you up myself. But I’m afraid that would tempt me to keep you away from the party for far too long.”
Steve shivered at the thought of Thor on his knees again, lapping his come mixed with Steve’s slick. He pushed away thoughts of what he would want to do with Thor, should they have an entire evening in a locked room together. It was far too distracting, and they’d been away long enough already. Sam and Natasha would come looking for him soon, if they weren’t already.
Thor passed Steve a handful of tissues for the mess, then with one last kiss and a promise to return shortly, he slipped out into the hallway, re-locking the door behind him. Steve sighed as he cleaned himself as best he could and waited for Thor to come back with a clean pair of underwear and pants. He wondered if anyone would notice that he was wearing different clothes. He wondered if anyone would notice he was wearing Thor’s clothes.
Steve ran his fingers over his collarbone where Thor’s mouth had hovered while he knotted. He wondered what it would be like to have Thor’s bite, to be mated and wear a little mark of love from his alpha, to touch it when he needed comfort the way Sam did with Natasha’s bite.
He signed and shook his head, disappointed at himself. One hookup and he was already thinking about mating? This is exactly why he avoided romance and sex. Especially where teammates were concerned. With everything the Avengers went through together, they had formed their own bonds. Steve did not want to confuse that bond with a romantic one just because of one encounter, no matter how passionate it had been.
And yet as he waited, his fingers kept drifting back up wistfully to his collarbone.
