Summary: as the title and prompt suggest, a man will do anything for the right potion ingredients. :D
A/N: Thanks to amanuensis1 for beta help. I'm nearly sure I haven't fully resolved the issue she objected to the most, but Snape-in-my-head is arguing about it, and do you know, he's a little bit stubborn. Heh. Also, eep, I'm a littttle bit late. Oops.
Trade Negotiations
"Come on, Snape. Surely you have it to spare. I need it. It's not as though you don't know I'm going to put it to good use. I've always been pretty good with making the medicinals, and buying them is prohibitive."
Snape stood in the doorway of his home in Spinner's End, leaning slightly forward so Charlie, shorter in the first place, felt the irritating need to either step down one step or arch his spine backward so as not to be standing with his nose all but buried in Snape's neck.
Considering Charlie was pretty sure he could overwhelm Snape handily in any physical contest, and he wasn't bad with his wand either, it was a good trick. He chose to crane his neck back and look up, aware of the manipulation and unwilling to give ground by stepping back.
"What, Mister Weasley, leads you to believe I give away powdered bat patagium? It's quite difficult to cure correctly, and I've not exactly a plentiful supply." He didn't respond to the issue of Charlie's proficiency with medicinals, but Charlie took that as tacit acknowledgement.
"Didn't expect you to giveit away. I just thought, you know, we could work a trade. I have scales, a couple of teeth, and a claw."
"Oh? And you believe this will be an adequate trade?"
"Dunno. What d'you need?"
"Well, as it happens, I don't need dragon claws or teeth." He hadn't retreated one inch, and Charlie's back was growing tired of the irritating position.
Fine, then. He stopped arching. "Scales, then?"
"I doubt you're carrying enough to make a fair trade."
Charlie sighed. "I don't suppose we could talk about this in the sitting room? It's bloody freezing out here, and since you've not much of a porch here, I'm stuck either dropping down and talking to your navel, or staying here and snuggling up to your throat."
Snape stood up straighter, which both made him more taller than Charlie and less looming. "I do not entertain."
"Yes, yes." Charlie waved a hand and took advantage of the change of dynamic to maneuver them both into the entry hall of Snape's old house. "I wasn't suggesting you serve cress sandwiches and berry tarts with wee lattice crusts. I merely thought negotiation was likely to involve a balancing scale and we might as well not freeze our bollocks off meantime."
"I am even less likely to serve cress sandwiches, than to entertain in general."
"Somehow I'm not surprised." Charlie took the parchment-wrapped parcel from his inner pocket and tossed it gently onto the side table. "Here's what I've brought. What can you trade? I really do need the patagium; two of my girls have wing rot, and Merlin knows substituting bird or lizard material really weakens the formula. I do want them not to be grounded."
Snape glared, then casually picked up the packet. "I can only spare an ounce in exchange for this," he said, watching Charlie's reaction carefully.
"Bugger. I need at least an ounce and a half," Charlie said. "Sure you're good for claws? They can sell as ornamentation, too, course. This one's perfect--not a chip or crack anywhere." He grinned. "The fellow it came from is the laziest dragon in the world, I think. If it can be accomplished with a snort, he doesn't even bother to breathe a proper flame.
"Excellent. You go sell it and bring me the coin."
"At nine at night on a Thursday in late autumn? Don't think that's going to work. I really want to start the potion tonight, Snape. Come on. You know I'm good for it."
"I know no such thing. That you've not failed to trade fairly before may denote merely a lack of opportunity, not a general trait regarding your trade practices."
Charlie rolled his eyes. "Gryffindor, in case you've managed to forget. We don't tend to play that way. Fine, then. What else might you take?"
"My stores are fairly well-stocked at the moment."
"Surely there's something."
"No. Well, there is one--no."
"Might as well say. No sense not at least seeing whether I have it to trade."
"It isn't that. The only other thing I require is of a more …personal nature." Snape looked Charlie up and down, apparently making some sort of assessment even as he spoke, a crease above his nose indicating he was perhaps regretting having said that.
Charlie raised a brow. "Oh? Care to elaborate?"
"It would require personal contact."
Well, hell. Now he was curious. "Snape, for fuck's sake. I'm in your front hall. I'm not afraid of touching you."
"Perhaps you are misunderstanding. The only other thing I need at this time, and do not have, is semen."
"You want me to take you back to the colony to gather? The dragons are seriously averse to providing--"
"Human."
"Oh. Er, oh. Can't you, uh…" Charlie made a gesture unlikely to be misunderstood.
"I could; however, I don't wish to, and also, I need a greater quantity, fresh, than is likely to issue forth from a single act. Furthermore, the formulation for which I need it is stronger if that quantity comes from more than one person."
Charlie raised his eyebrows further and stepped further into the hall, looking around. "So, what, you want me to jerk off with you? In exchange for the patagium?"
"If you're not interested, you could simply say so. Also, I believe I indicated that would be in exchange for the half-ounce beyond what your scales will buy you." He paused, then spoke again, a rush of words it took Charlie a moment to parse, out of character compared to his usual clear diction. "And no, as long as I'm producing semen with someone else present, I'd prefer it not be by masturbation."
Charlie pushed the door, which had been standing an inch ajar, the rest of the way shut, and leaned back against it, arms folded over his chest as he considered this unexpected proposition. "I'm not not interested. However, I must say I've never before had anyone find my dick more valuable than a dragon tooth."
Snape glared. "Do we have a deal, or do we not? And a dragon tooth, while certainly valuable in its own right, is eminently unsuitable for the use to which I intend--"
"There are always engorgement charms," Charlie said with a smirk. He shrugged off his coat as he spoke, and nodded. "And yes, I believe we have a deal."
Snape stared at him. "We …do?"
"What, you didn't think I'd take you up on it? Honestly. Your idea. And believe it or not, I am rather fond of fucking. Seems to me what you're proposing is a good old-fashioned no-strings tumble. 'S my favorite kind." Charlie tugged his shirt off over his head. "Where?"
"What?" Snape was more rattled than seemed reasonable, but then, Charlie supposed he'd probably thrown him by accepting.
"Drafty here in the entrance hall. Doesn't seem like it would be much fun, and the floor's stone. Probably too damn cold. So. Bed? Sitting room sofa? What?"
"I." Snape shook his head, then drew himself up tall. "I shall have to organize the collection materials. In the laboratory."
Charlie shrugged. "Got a couch in there? Or shall I just sit in here and entertain myself until you're ready?" He pointed his wand at the living room fireplace and encouraged the fire to grow hotter, then directed another log into place from the bin nearby. "Might as well be warm," he said, crossing to the couch and sitting down, trousers unfastened, one hand reaching inside.
Snape stood for a moment, then blinked. "Yes. You remain here. I shall return momentarily."
Charlie grinned and squeezed his cock slowly, letting his head fall back as he stroked and waited. Snape was only gone two minutes, and in that time, Charlie had envisioned a number of promising ways to entertain them for the evening. Just because he'd not come here expecting this didn't mean he wasn't willing to be thoroughly flexible about the concept.
"Mister Weasley."
"Charlie," Charlie corrected. "I'm not especially fond of that level of formality when we're working on making me come."
"I see. Charlie. Now, then."
Charlie stood and crossed to where Snape was standing before the fire holding a beaker, his wand, some sort of treated parchment, and a phial. "What's all this?"
"This is a beaker--"
"Yes, that part, I observed on my own." Charlie set about unbuttoning Snape's robes. "Go on."
"That. What are you doing?"
"I rather thought getting to some skin might be useful," Charlie said. "So. Beaker…?"
"Into which we shall each ejaculate."
"Sexy when you put it like that," Charlie said.
"As I believe I indicated, I do require the ingredient. I do not require irrelevant 'sexiness.' Also, I need it to be reasonably free of contaminants and of good quantity. I assume you are in good health?"
Charlie reached into the open robes. "Course. Clean bill of health for certification just last month." He stepped closer and reached further, and his own cock, which had deflated somewhat at the discussion of beakers and contaminants, surged back to life as his fingers closed around Snape's.
"In that case, only a cleaning charm shall be required."
"Fine." Charlie stepped closer, letting their cocks touch, wrapping his hand around them both at once. Snape groaned, standing stock-still and holding his assorted supplies out to both sides. "Go on, then. Cleaning charm."
"It would be more effective. To do it. Right before. We. Mister Weasley, I thought I indicated I didn't intent to engage in simple masturbation."
"Hm. And I believe I indicated my name is Charlie, and also, if you want me to fuck you, you need to lose the rest of this clothing and give me your arse."
Snape fastidiously set down his materials on the end table, on top of Root Clippings Quarterly, then removed his robe and stood awkwardly.
Charlie grinned. "Arse?"
"Yes, but first I require you to understand the task."
Charlie laughed out loud. "All right, I do generally try to be at least a little bit discreet and all, but I have done this before."
"For this purpose?"
"The purpose of coming? Yes."
"The purpose of producing a potion ingredient."
Charlie rolled his eyes and stepped back, going back to stroking his own cock alone. "Fine. Explain."
Snape watched his hand going up and down and swallowed. "Er. Perhaps you ought to stop doing that."
"Snape, you--"
"Severus. If I'm to call you Charlie."
"Fair enough. Severus, you have the maddening-makingest approach to sex ever." He considered, briefly, that this might be too much trouble, but at this point, that would certainly only mean going to a pub and finding someone else to fuck, and that wouldn't really be any better than this. And besides, it'd take longer. He shrugged and gestured. "Come on. Come here. I promise, it'll be good, and you'll come, and I'll come, and it'll be lovely."
Snape sighed. "I'm sure it will, but--"
"But nothing. It'll be good. Really." Charlie reached for Snape's cock again, stroking them each with one hand now. "Where to? Over the desk? Against a wall? In front of the fire? Something to be said for any of those."
"Before the fire will be fine," Snape said, apparently convinced there was no further need to explain the mechanics.
Charlie nodded and walked backwards, pulling Snape with him. Snape stopped and picked up his beaker and supplies, then followed readily enough, and knelt on the rug. Charlie moved around behind him and then reached to go back to stroking, his own cock sliding gently against Snape's arse. "All right?"
"Hmm." Snape nodded and bent forward, supporting himself on his elbows. "Go on, then."
Charlie reached and Summoned his own wand to perform a simple lube-and-stretch charm, then bent forward himself, pressing his cock against Snape's hole, guiding with one hand and running the other along the tense muscles of Snape's back.
Snape gasped, not moving.
"What?" Charlie asked.
"Just. Do that again. Wait. Where have I left my beaker?"
Charlie chuckled and located the glass container to one side. "Needing it so soon?"
"I merely wish. Do that again. To be prepared."
"Mm-hmm." Charlie set a pace and did that again, and again, without further comment, gripping Snape's hips and watching as he moved a hand back to stroke himself, grunting louder with each thrust.
"I--" Snape began, and then he was contracting around Charlie, scrabbling at his beaker and his cock.
And then, to Charlie's surprise, Snape surged forward, away from him, and turned, wand in hand. "What--?"
Snape performed a sudden harsh thorough cleaning charm on Charlie's cock, then held forward the beaker. Charlie blinked. "Ouch."
"I believe I was clear, if less than thorough. Contamination would be bad, and you've just been…"
"I see." Charlie lifted his eyebrows again, and gave his cock an experimental tug. It didn't hurt, really, so much as he'd been startled, and his cock was still quite interested in coming, so he took a deep breath and reached for Snape's hand. Snape looked up, puzzled, and Charlie shrugged. "Only fair. I made you come, now you make me."
Snape nodded and caught up his lower lip between his teeth, squeezing and tugging, twisting gently until Charlie was panting and pushing and spilling into the little cup.
He sat back, leaning against the front edge of the couch, and ran his hand through his hair. Snape had gone back to his cache of supplies and was dropping drips of fluid on the parchment. Evidently satisfied, he poured the contents of the phial into the beaker, then covered it and set it aside as he went to retrieve his clothes.
"So, Severus?"
Snape spun, startled; evidently he'd not expected Charlie to talk again. "You'll get your patagium."
"Wasn't what I was going to ask. How often do you need this ingredient?"
"Occasionally."
Charlie nodded. "Is this usually how you obtain it?"
"No."
"How do you usually?"
"There are usually young men about who are willing to earn a bit of coin for a few minutes easy work." He didn't turn to look at Charlie as he spoke.
"You pay for boys to come for you in a clean cup."
"Occasionally."
"Huh. Well, I have a suggestion."
"I believe we're past the point of suggestions." As Snape buttoned his robe to the chin his usual starched demeanor returned.
"Not necessarily. I was going to say, next time? I'd rather just jerk off for you first. If you can given me a few minutes, I will be more than happy to fuck you blind after, and then we don't have to scour my cock right when all I want is to come. Or we could come up with, I don't know, pretty much any other approach. That was shocking."
"…Next time?"
"Oi, besides the scouring part, it was good. No reason to pay money for that. I can provide that as often as you want, in exchange for the occasional supply of an ingredient or two…? If you're interested."
"Perhaps," Snape said after along moment, "we can reach an agreement."
Charlie patted the floor next to himself. "I imagine we can. I'm flexible, you know."
"Apparently. I wasn't expecting you to accept my…"
"Proposition?"
"Yes."
"I thought perhaps. However, it worked out all right. You wind up with enough?"
"What? Yes."
"You sure?"
"What?"
"Well. I wanted to start the stuff for the girls, but after that? I thought perhaps if you needed more…"
Snape blinked, then shook his head. "I believe if we're to pursue this arrangement, we shall have to experiment with your suggestion. In order to see what arrangement works best, of course."
"Of course. Good idea." Charlie stood and fastened his trousers. "Back in an hour, then."
"You could--"
"Hmm?"
"I have a working laboratory here."
"Point. Got everything I'll need?"
"Yes."
"And the price?"
"We can reach an agreement."
Charlie grinned. "Back in ten minutes."
