A/N: Thank you to the mods at House of Snarry for organizing the Snarry AUctober Fest. This is my first Snarry piece, so I'm very excited to have it be a part of this collection.

Thank you to my alpha InspiraPens for helping me brainstorm this.

Thank you to my wonderful betas TheFrenchPress, charlie9646, and starkidsftw. Each of you made it a better story.

A knock pulled Severus out of his gleeful reverie where he sat at his desk. He grumbled. Slashing parchment with red ink was one of the few joys he still allowed himself after the war. With his cover as a spy having been revealed, his students seemed to think they could treat him with some amount of...teasing acceptance.

He hated it.

It was hard to maintain as severe a countenance all the time when he wasn't doing it for a war, so he allowed himself to be as severe as he liked with his essay marking. That generally curtailed the worst of the simpering behavior.

"Come in," he called, begrudgingly placing down his quill.

A mop of messy black hair led first, followed by a small wave as Harry Potter pushed his glasses up his nose with his other hand. "Hullo, Severus," the twenty-five year old DADA professor said, still barely leaning around the doorframe to avoid a hex. "Is now a good time?"

Snape sighed through his nose and closed his eyes briefly before opening them. "I suppose, Mr. Potter."

Harry entered and sauntered over to a couch on the side of the room, plopping down before removing his glasses to wipe them on his shirt. "I really wish you'd just call me Harry," he said.

"I'll consider it," Severus said, before maneuvering the conversation back to whatever the interruption was about. "What do you need?"

Harry pushed his hand through his hair, scarlet tingeing his cheeks. He placed the glasses back on his face and clasped his hands in front of him, looking down.

In that moment, Severus didn't think he looked like a formidable professor or like the man who had taken down the most evil wizard of all time. If he had to guess, he thought the other professor looked rather embarrassed.

"This is an awkward situation I find myself in," Harry began timidly, "but I don't know who else to ask. I thought perhaps you might have some advice...man to man."

Severus felt the blood creep into his face in anticipatory embarrassment. In the five years since Harry had begun working at Hogwarts, they had formed an unlikely but temperamental friendship. They frequently hosted a dueling club together, but Harry's disposition still often riled Severus up until he found himself storming off back to the dungeons and sleeping fitfully. They had been searching for a balance for years, but it was never simple. It always felt like there was something they had yet to discuss, just out of reach; out of the collective consciousness.

Something always a little off.

Oh well. Perhaps it was just about Lily? Perhaps the awkwardness between them would always be about Severus loving the boy's mother once upon a time.

But he wasn't quite sure that was it.

Shaking his head to bring himself back to the conversation, Severus sized Harry up, the man's blush darkening even more.

"That look could kill, you know," Harry quipped.

"It hasn't yet."

The DADA professor rolled his bespectacled eyes. "Listen, I just...I've been having some trouble that I thought, perhaps, you'd have a potion for."

"A potion."

"Yes."

"You want a potion."

Harry shifted. "Yes."

"Something you cannot go to Pomfrey for?"

Harry couldn't meet his eyes. Bingo.

"Is this about your penis, Mr. Potter?"

He buried his face in his hands. "How are you possibly making this worse than it already was?"

"A talent, I'm sure."

Harry looked at him with mild annoyance. "Yes, it's about my dick. Merlin."

"Well, out with it then," Severus said, crossing his arms and leaning back.

Harry blanched, opening his mouth and closing it several times without words. "I—I thought we could, um—"

Severus raised an eyebrow. "The problem, Mr. Potter. Out with the problem."

"Oh." Harry was oscillating so fast between too much blood in his head and not enough that Severus thought he might pass out. "Well, you see...I've been having trouble for a while now with being able to...ya know…" He gestured lamely towards his nether regions.

"Maintain an erection?" Snape asked point blank.

"Merlin, no! That would almost be easier at this point." Harry pushed his glasses up again. "No, that's no problem, it's the after part. I had a few dates this month, just various people, and not once could I…" Harry pushed his hand out from in front of him, avoiding saying the words.

"Come?"

Severus sat unaffected watching Harry look up at the ceiling.

"Yes."

"And you think I can help you with that?"

"I thought maybe you had a potion that could fix it."

"Mr. Potter, I don't think your inability to please a witch is something I can fix with a potion."

"I please them!" Harry spluttered indignantly. "I just can't finish. And it's not just witches."

Severus quirked a brow minutely. That was news.

Harry rubbed the back of his neck. "They're lovely people, I'm having a good time, but for some reason...nothing."

The older man rocked back in his chair and considered. "And yet you haven't sought out Pomfrey's help?"

Harry rolled his eyes. "Oh yes, that's a conversation I want to have. Hello Madam Pomfrey, I know you can't personally relate, but my dick is broken. Mind fixing it up?" He rolled his head to look at his colleague incredulously.

The ridiculousness caused Severus to snort. "Fair point."

"Can you help me?" Harry asked.

"You know, some people might consider stamina a good thing," Severus replied, enjoying himself far too much.

"I'd like to come again sometime in this lifetime," Harry deadpanned.

"I don't know that I am the right person to be assisting you with your sex life, Mr. Potter."

"You really should call me Harry if we're talking about my dick. I'm not a child, Severus. I haven't been for years."

Severus sucked his teeth. "Fine. I don't know if I can help you, Harry."

The other man looked desperate. "You have to have something," he said animatedly, kneeling up on the couch to better face Snape. "How would you feel if your dick was broken in front of a date? How would you feel if it had broken in front of my mother?"

Severus narrowed his eyes. The boy was clever. "Low blow."

Harry pointed a finger at him. "Fair shot and you know it." He looked at him beseechingly.

"Oh for fuck's sake, fine." Severus rolled his eyes and stood, walking over to a locked cabinet before opening it wandlessly. He pulled a vial out, sealing the door again.

Walking in front of the couch to stand in front of the seated, desperate man, he handed it to him without a word.

Harry took it from him, his hand brushing Severus' in the process. A small shiver ran down the Potions Master's spine.

A small smile crept over Harry's face. "Thanks."

"If you are satisfied, you may leave now." Severus turned back to his desk and sat behind it, putting distance between himself and his fellow professor.

Harry stood, fidgeting with the bottle in his hands. He began walking towards the door before turning around suddenly.

"You weren't surprised," he said. "That it's blokes too."

Severus' expression betrayed nothing. "I was actually. I assumed Miss Weasley was enough for you."

Harry rolled his eyes. "Ginny and I haven't been together in years, Severus. And it was never about her not being enough. I just...fancy blokes too."

Harry gave him a look as if waiting for something. An unspoken question hung in the air.

Snape nodded once. "I...understand."

He watched Harry suck his cheeks in trying to avoid grinning. "Right."

Harry turned and started back towards the door again. Severus watched him, wanting to say something, but as usual, not knowing what.

Harry turned around first, leaning against the closed door frame, his hand on the knob. "Thanks for this, by the way. I know we're not exactly friends, but...I think we've come a long way the last few years. And I––I like spending time around the castle with you. It's been...nice. Pleasant. Right." He pushed his hand through his hair, red creeping back into his cheeks. "Right," he repeated. And he turned the doorknob.

"Harry," Snape said, stopping him mid-action. The younger man turned back slightly, his eyes expectant. Severus wasn't even entirely sure what he wanted to say. He just hadn't hated the interaction. "I should like to know if the potion works. It would be...useful information for me to have. In working on the potion."

Harry paused, blinking. "Of course. For mastery, of course."

"Of course."

He grinned just a little, one side of his face picking up in amusement. "I'll be sure to let you know. But I don't have any more dates lined up, so you may have to wait a while."

"It will work on your own as well."

"Good to know," Harry said, tilting his head to the side. "So perhaps sooner than later."

Something was itching at Snape's mind and he had to know. "None of the witches and wizards this month caught your interest?" Severus asked, trying to sound unaffected.

Harry shrugged. "Not being able to come with someone is usually a mood killer, but there's no love lost really. I was just passing the time."

"Until what?"

Harry ducked his head quickly, hiding most of a smile, but not before Severus caught a sparkle in his eyes. The man turned the doorknob and opened the door before glancing up. With a very deliberate look, he slowly took in the Potions Master before nodding once.

"Goodnight, Severus."

And shut the door gently behind him.

Severus was left sitting there, arms crossed, leaning back.

Harry would try the potion, and then he'd report back.

For two people such as them, perhaps that was the best way to begin.
