“I’ve got a unique prototype for you tonight,” Harry says, ushering Severus into the bedroom the next week. “Might eventually offer a version of it for sale but… well. This one is special, just for us. You’ll see.”
Severus says nothing, merely stands in the middle of the room and eyes the box on Harry’s bed with one delicately raised brow.
“Yeah, go on, open it.” Harry shoves his hands in his pockets to keep from rubbing them gleefully like some sort of cartoon villain. “Open your robes and let it touch your bare skin. Chest or stomach or prick, whatever you’re comfortable with.”
“That sounds ominous.” Still, Severus does as Harry requests, unbuttoning his robes and the (black, still always black) dress shirt underneath, then removes the lid from the box and lifts out the exquisitely detailed coiled silver snake. Harry spent a lot of time getting the texture of the scales just right, the shine on the eyes, everything down to the duller silver-gray taper of the tail. It’s a work of art, and they both know it. Severus sighs, then turns the snake sideways and presses the belly flat to his abdomen.
The snake immediately comes to life, exactly as Harry has charmed it to. Before Severus can object, it has coiled its tail around his waist for balance and is already slithering down into his trousers. Harry has to repress a laugh at the startled look on Severus’s face - a reaction Severus rarely lets anyone see - as the snake coils snugly around his cock inside his pants.
“Want to see?” Harry asks nonchalantly. “Go ahead, check in the mirror. I guarantee you’ll like the visual.”
Severus rolls his eyes but lowers his pants and follows Harry’s instructions. Even with his pale complexion, the contrast between skin and silver scale is striking. Severus walks into the en-suite loo, then stops dead and stares at his reflection.
“That’s the basic setup,” Harry tells him conversationally as Severus gapes. His cock noticeably tries to swell, but the snake keeps it from succeeding. “The ones I’ll be selling have a password for this that can be keyed to a single user - meaning you can’t take it off, only I can. Or, for a bit more control… serpexoucia.” The snake immediately loops a bit of its length around Severus’s sac, tugging it away from his body and constricting enough to make Severus gasp. “At my command, it can do anything from gently massaging you to permanent damage. Helpful for those who enjoy testing their pain tolerance in very specific ways.”
Severus has endured enough pain for a lifetime, Harry knows, but he does enjoy the threat of more as long as Harry never takes it too far. Luckily his “I’m too controlled to show emotions” facade drops once he’s sufficiently aroused. After that he’s easy to read. Even now, barely minutes after they’ve started, he’s already flushed and breathing more heavily. Harry can’t wait to see how much Severus will enjoy being denied.
“This one is special, though,” Harry says, and leads Severus back to the middle of the carpet. “I think… tonight, I want you to strip the rest of the way and kneel here for me. Legs apart, nice and wide, so I can see. You can sit back on your heels. I want to show you the tricks I’ve charmed into this particular toy - tricks no one else’s will do. This is just for you and me.”
Severus sheds his clothes efficiently, folding them and laying them on Harry’s dresser before sinking to his knees. He bows his head and places his hands docilely on his thighs, the very picture of submission other than the fact that his cock is still fighting with its serpentine cage. That part isn’t Severus’s fault, though, so Harry chooses not to comment.
“Ready to see what else our special toy can do?” Harry asks. Severus replies with a silent nod. “The important part is, I’m the only Parseltongue in Britain. So I’m the only one who can make it do this.” Harry hisses the command and the snake immediately shifts itself into position: its tail sliding into Severus’s arse, its head poised over the head of Severus’s cock as if to strike. It doesn’t - that would be more pain than Severus would enjoy - but its mouth goes nose-to-tip with Severus’s prick. And…
“Oh!”
“I realize we haven’t played with urethral sounds before,” Harry says conversationally, as if Severus isn’t practically vibrating with need, “but what do you think?”
The snake’s thin silver tongue dips in and out of Severus’s slit again, making Severus’s mouth drop open. One of the lovelier details of this design, and the one Harry is most hoping Severus will appreciate, is how the mass of the snake can reapportion itself according to Harry’s whims. Currently the twin prongs of the snake’s tongue are all but fused together to make one thin rod, but Harry can make them thicken a bit at the tip for extra stimulation or lengthen to go deeper if Severus seems to be enjoying the sensation. The snake’s coils keep his prick flaccid and small but still perfectly straight, which means the tongue can reach surprisingly deep if Harry wants it to. It was certainly a novel feeling when he tried it on himself earlier in the week.
“It’s inside my cock,” Severus breathes, still too shocked and turned on to hide his emotions like he normally would. “It’s… odd, not being able to get hard even though my body clearly wants to.”
“You like how I’ve taken away that ability. You can’t control whether your body has an erection or not, but I can.”
Severus groans, long and low, in lieu of a real reply. He always does seem to respond better to the intellectual aspects of their games - to Harry pointing out how thoroughly he’s overpowered the man, how little choice Severus has but to obey. They both know Harry would stop if Severus asked, that Severus could simply stop coming over to Harry’s flat on Friday evenings if he really didn’t trust him, but they both also know that Severus loves this and Harry loves indulging him.
Whoever would have thought the once-antagonists would be sharing mind-blowing orgasms on the regular?
“I could simply send you home like this, you know,” Harry comments. “The snake is keyed to my parseltongue commands, which means you couldn’t remove it even if you were to go inventing your own spells. It does have a charm on it to vanish waste - the same one they use at St. Mungo’s. You could release your bladder right now and never have to take it out. I could leave it on you for days, weeks, even years, and you’d suffer no hygiene issues. Think about how convenient that would be, never having to leave your work to use the loo.”
Severus’s eyes grow wide. “Fuck,” he breathes.
“Oh, that too.” Harry hisses another command and the snake’s tail thickens, lengthens inside Severus’s arse, until it’s a nice fat plug and probably stretching him something heavenly. “Vanishing charms on both ends, so you never have to think about your excretory system again. And when I want to make use of your lovely arse…” He sits on the floor beside Severus and trails a fingertip down the man’s spine, hissing to the snake again. When he gets to Severus’s hole, the snake’s tail thins and shifts again into a wide spiral - holding him open enough for Harry to get a finger inside without even having to work at it. “See how easy that is?” he asks. “Your own personal deluxe model, which can take on any size or shape or configuration I request it to. I can tell it to prod your prostate for hours, or keep you wide and ready for me, or simply prevent you from being able to play with it yourself until I want to stick my prick in you again. I can charm it to squeeze your bollocks painfully if you so much as touch your cock or your hole without my permission. Do you like knowing that your body belongs to me now?”
Severus swallows hard. “I… I don’t like liking it, but… yes. Apparently I do.”
“So do I,” Harry whispers in Severus’s ear, and quickly shucks his own clothes. His cock has been hard pretty much since the moment Severus walked in the door, and it feels lovely to plaster himself to the man’s bony back and rut lazily against the cleft of his arse. “I plan to make use of this delightful toy even after we’ve thoroughly run it through its paces, because I love how you flush when you’re aroused. It goes all the way down your shoulders and chest.” He murmurs the words against the back of Severus’s neck, and the flush in question deepens. Severus’s fingers twitch on his thighs, but he does an admirable job of holding himself back. “I know you can keep yourself very still,” Harry says, “so I want you to do that now. And I’m going to fuck you while you’re all caged up and can’t even get hard, much less come. I’m going to fuck your arse and the snake is going to fuck your prick and you’re going to be so bloody desperate you’ll beg. I love it when you beg me, Severus. I know you always try to hold out and it never works.”
Severus lets out a little whimper he’d probably never admit to in any other situation, but he holds perfectly still as Harry lines himself up and takes ahold of Severus’s hips for leverage. The silver snake obediently shrinks back from Severus’s arse at a single whisper from Harry, keeping just the tip of its tail inside Severus’s hole and occasionally undulating in a way that seems to make Severus shiver. Harry casts a lubrication spell and slides himself inside in small increments, until he’s fully seated in Severus’s gorgeous arse and Severus is vibrating with the effort of not moving a muscle. Then Harry re-activates the snake’s tongue.
“Oh!” Severus gasps, his composure almost immediately broken. Harry pumps in and out with powerful strokes, in a close rhythm with the silver sound currently dipping in and out of Severus’s prick. So Severus really is getting fucked from two directions at once, and all he can do is take it. And to beg, which he does even sooner than Harry expects. “Please,” he moans. “Pleasepleasepleaseplease!”
“You want to come?”
“Yes!”
“No,” Harry says simply. “You don’t even get to get hard. I’m fucking your arse and the snake is fucking your limp little cock because I like it, not because it’s supposed to do anything for you. Maybe I’ll keep this toy on you until next week, just to see how it does. And maybe next week my new invention will be some novel variety of nipple clamps, so we won’t even have to take your trousers off to play. I’m sure eventually I’d need access to your pretty hole again, but who knows how long that will be? Could be months, could be never. You don’t really need your cock, right?” He plasters himself to Severus’s upper back and focuses on giving Severus nice, deep strokes with his hips. “I mean, you wouldn’t be able to go fuck around with anyone else, at least not anything beyond doling out blow jobs and getting nothing in return, but think about how much more you’ll be able to concentrate on potions without the distraction of ever getting an erection again!”
Severus moans weakly. “I… I…”
“Guess I might as well fill your mouth too, seeing as you’re not using it for intelligent conversation tonight,” Harry says with false nonchalance. He lets go of Severus’s hip with one hand and presses two fingertips against Severus’s lips. “Open.”
Severus gasps and starts sucking on Harry’s fingers like there’s no tomorrow. Harry presses down hard on Severus’s tongue, preventing him from trying anything fancy, but Severus just keeps moaning and allows Harry to do whatever he likes. It’s bloody gorgeous, Severus’s submission, and it’s all Harry can do to not come right then and there. He usually does promise Severus at least one orgasm, though, and long-term denial isn’t something you spring on your partner (are they partners?) without advance warning and a lot of negotiation. The threat of it, though, is apparently something they’ll have to revisit. Later.
“I’m going to come,” Harry warns, as he feels his bollocks drawing up in preparation. “You want to come too?”
Severus nods frantically, mouth still working Harry’s fingers. Harry can’t see his face from this angle but he would bet galleons that Severus’s cheeks were moist with frustrated tears. He always comes the hardest when he’s submitted so thoroughly…
With a final parseltongue command, Harry orders the snake to withdraw its tongue and to loosen its coils. Severus’s cock springs to full hardness impressively quickly - a sure sign of how close to the edge Severus already is. Harry slides his hand between the snake and Severus’s cock and has barely touched him before Severus is letting out a muffled shout and coming all over Harry’s rug. Harry follows him over the edge in moments, hugging Severus to him with one hand on his cock and one still stuck in his mouth and both starting to feel unpleasantly moist now that the haze of arousal is clearing. The snake gleams brightly as it coils itself up on the floor - directly in the puddle of Severus’s come, Harry notes - and goes back to sleep.
“Bed,” Harry pants, and hauls Severus up to lie beside him. He and Severus sprawl nude, staring at the ceiling, for several minutes before Harry stops seeing stars.
“I wasn’t sure you were going to let me, in the end,” Severus finally mumbles, not looking at Harry. “I… honestly couldn’t predict.”
“Would you have preferred that?” Harry turns to his side to see Severus more clearly, even though Severus is conspicuously still not looking at him.
“No. Actually… I don’t know. Maybe.”
“You’ve enjoyed when I’ve teased at other times, threatening to not let you come, but that was only ever for the duration of the scene. Not even the whole evening, usually.” Harry watches the emotions pass over Severus’s face. He never lets anyone else see this, he thinks to himself. Only me. And only at times like this, when we’ve both let our guard down. “I hoped you’d appreciate the possibilities, even if we didn’t capitalize on them.”
“You… overwhelm me,” Severus admits. “In a good way. Every time I think I have the measure of you, you surprise me. There aren’t many people who can do that. And you get me out of my own head, which I also appreciate.”
“I do think you’ve got a bit of a power kink,” Harry says.
Severus barks out a laugh. “Perhaps more than a bit. I have no doubt you could make me come even with that bloody toy on if you wanted to, just by wishing it badly enough. You wouldn’t even need to develop a spell.”
“Oh, that would be interesting.” Harry trails a hand over Severus’s chest. The man’s muscles are surprisingly well-defined, for how skinny he is. “I bet I could find a way to make that happen. Perhaps even when I wasn’t there, if I cast the spell right. You could wear the toy all week, causing you to think of me every waking minute, and I could give you random orgasms from halfway across London. I might time it for when I know you’re in a meeting at the Ministry, or I might give you wet dreams every night and make you wake up aching.”
Severus is clearly trying to play it cool, Harry can tell, but the giant leap of his Adam’s apple gives away how much he likes the idea. “Perhaps,” he says, his voice cracking.
“Actually…” Harry props himself up one elbow, the better to be the one looming over Severus for once. “It’s been a while since we’ve played around with just plain magic. Want to see if I can get you hard again by channeling my power through your cock? We can try the other extreme - how many times can I make you come before you go home tonight?” He idly moves his hand down over Severus’s groin and wills some of his magic into his palm. Severus’s eyes widen and his prick makes a valiant effort at getting hard well before his refractory period usually allows. “I bet I can,” Harry adds teasingly.
“I bet you’re right,” Severus admits, giving an aborted hip thrust into Harry’s hand. “And after… well, if you want to stress-test your new invention for longer-term wear, I suppose I wouldn’t be opposed.”
