Work Text:
Severus had been in many strange positions before – most of which he didn’t care to contemplate at the moment. He’d been flung upside down and tossed around in the air; he’d been jostled awkwardly on broomsticks and flying motorbikes; and when he thought about the various sex positions he had tried with Sirius, several might have convinced an onlooker that he was a former acrobat who’d just gone a bit rusty but was otherwise still quite flexible.
Out of everything, though, this was perhaps the most unsettling position he’d willingly put himself into: On the bed, resting on all fours, a pillow under his hips and his arse up in the air. The only consolation was that he wasn’t completely nude; his long nightshirt had been rucked up around his waist, but he did have the option to cover himself at any time, and it was like a safety switch waiting on standby.
“You remember our safeword, don’t you?” Sirius asked somewhere behind him.
“Yes,” Severus hissed into the sheets.
“Say it, just so we’re clear.”
Severus rolled his eyes. “Peaches.”
“Excellent!” The sudden slap to his rear made him jump, and he turned to glare at Sirius, who simply grinned at him. “Ready to begin, then?”
“Let’s.” Severus settled himself again and clutched the pillow beneath him. For some reason, the very idea of what they were about to do was making him nervous. Sex between them was typically a spontaneous thing, born of a sudden burst of inspiration that allowed him to turn off his brain and just feel for once. But this had been prearranged between them, and he couldn’t help getting worked up over it.
The bed shifted behind him, and he tensed. Sirius seemed to realize it; his hands came to rest on his hips, smoothing up and down gently. “Not to worry, love,” he said bracingly. “You’ll like it, guaranteed! If I don’t have you completely undone in five minutes, you get your money back and a voucher for 50% off next time.”
“Would you stop talking nonsense,” Severus grumbled, “and just do it?” The waiting was killing him. He couldn’t believe he’d allowed this, couldn’t believe he’d agreed to let Sirius put his mouth—
Hot breath was suddenly ghosting over his bare arse, and he shivered, willing himself to relax. He could feel his muscles bunching under Sirius’ hands, and he took in a deep breath to steady himself. He reasoned that he had allowed Sirius to do much dirtier things to him, he’d allowed the man inside him so many times, how was this any different?
Sirius licked a hot trail directly across his asshole, and he forgot his objections. It felt so strange, so alien. He shut his eyes and tried to decide whether it was a good feeling or a bad one. The action was repeated, and it swayed his opinion slightly more towards positive – it wasn’t bad, necessarily.
Then came a kiss to his hole, and he bit his lower lip, stifling a moan. Oh, that was… nice. Not bad at all. Another followed, and another, and soon that tongue was rejoining the party, and Severus’ mind just went blank.
He had done a lot of prep work for this, sitting in the bath for an hour and using spells to clean himself inside and out. All the while, tension had been building. Now it drained out of him in one great surge, leaving him loose and pliant in Sirius’ hands. Severus could feel the blood rushing to his face and elsewhere, and he shifted his hips slightly to put some pressure on his groin against the pillow. Sirius swirled his tongue once more before pulling up with a chuckle.
“What’d I tell you? Not bad, eh?”
“Nnh—no, not… not bad,” Severus muttered, eyes still closed and hips still rocking ever so slightly back and forth.
“Think you could come like this?”
“We certainly won’t find out with you wasting time talking, will we?” Inside that biting comment was a plea, and he knew that Sirius heard it. The animagus returned to work with enthusiasm, and Severus returned to focusing intensely on his breathing.
How strange, he thought, to feel such a thing. He never realized how sensitive it was, nor how deft and agile the human tongue could be. And it wasn’t just the tongue; Sirius was employing all of himself that he could, his lips and fingers and even his breath, to produce such delectable sensations. Try as he might, Severus found that he couldn’t control himself completely. His legs twitched, his fingers dug at the sheets and the pillow, and his damnable hips just kept pushing back, demanding more and setting a pace that Sirius automatically followed.
He didn’t need a hand on his cock, but it was certainly appreciated as Sirius reached under him and took hold of it. The pleasure deepened then, engulfing his entire being before redirecting to the most intimate parts of him. He knew then that he wasn’t going to last long. Sirius was working him slow and steady, but that was precisely what got Severus going. The power Sirius held then, the control he had of himself, all left Severus shaking and needy, stripped of his defenses and begging for more – quite literally.
“Patience,” Sirius said as he came up for air, and Severus went bright red to realize that he’d started pleading aloud at some point. Or perhaps Sirius was just that good at reading him. He clamped his mouth shut, buried his face in the mattress, as Sirius dove again, and he tried to ride it out without making a fool of himself.
This act felt, above all else they had done, like something forbidden. He’d let Sirius see him in almost every imaginable way – his body and even deeper than that, pieces of himself even he didn’t know were there. He had done things with Sirius that he’d never thought of doing with anyone else, and most of it had started when they’d still loathed the sight of each other. But this was different, somehow. This was like an affirmation that their relationship, much like themselves, had evolved. That they had grown together.
Sentimental, he chided himself, just as Sirius pushed his tongue inside and sent his thoughts spiraling away again.
It felt ridiculously good. He would admit that. Orgasm snuck up on him as he was distracted by the things Sirius was doing to him, and he arched his back and cried out as he came, eyes wide open but blind to everything but the pleasure.
He trembled as he slowly lowered himself onto his stomach, and Sirius moved away for just a moment. Severus groaned at the loss of contact, only to be covered by warmth as that solid body settled atop him, Sirius’ prick nestling in the slick crack of his arse. “Stay still a moment,” Sirius grunted, and Severus barely had the presence of mind to comply, holding onto the sheets for dear life as Sirius took hold of his hips and began to thrust against him.
It wasn’t long before Sirius went rigid, and warmth pooled between them. Severus gasped as he pressed back into his lover, feeling how his cock twitched and spasmed, trapped in that slippery rut. He strained to keep himself taut, his body offering firm resistance against Sirius’ and heightening the friction until the animagus was spent, limp and panting against Severus’ back.
Carefully, Severus rolled onto one side, dislodging the heavier man atop him. Sirius pulled him close, away from the wet spot and into the warmth of his arms, his fingers playing with Severus’ hair. “So?” he asked.
“Hmm.” Severus’ eyes were closed, his entire body relaxed in complete and utter contentment.
“What did you think?” Sirius prompted again, nudging Severus’ shoulder.
“I think I’d like to kiss you,” Severus sighed. “But you should brush your teeth first.”
Laughing, Sirius bent down to offer his lips, but Severus pushed him away, onyx eyes finally opening again. “I’m serious!” he snarled. “I’m not letting your mouth anywhere near me until you go wash!”
“Spoilsport,” Sirius huffed as he reluctantly got out of bed.
“Be sure to get your beard, as well!” Severus called.
“Fine, fine!”
“And your hair! It does tend to get in the way…”
“Merlin’s saggy left bollock, Sev! Shall I just shower, then?” Sirius was getting irritated.
For once, Severus wasn’t in the mood to argue with him. He stood up and stretched, letting his nightshirt fall down around his knees. “Why not?” he purred, his tone immediately taking Sirius off guard. “I might join you.”
With a grin, Sirius went to run the faucet.
