Try the corner cupboard

You tiptoe over to the corner cupboard. Quickly, you look over your shoulder to make sure that Snape is still out of the room, then open the door. The two half of the cupboard has many shelves filled with assorted bottles and boxes. Each container has a small, neatly written label. The bottom half of the cupboard is an empty space. You presume that Snape has taken out whatever box is usually kept there.

Quickly, you run over the list of ingredients you’re looking for in your head – Ashwinder eggs, Murtlap tentacles, Occamy eggshells. You start looking at some of the labels, hoping that your luck will change. Unfortunately, although you see many rare potion ingredients, none of them are the ones that you’re looking for.

“I thought I closed that door”, a soft voice says behind you.

You spin around and see Snape standing in the doorway to the other room, staring in your direction. As he approaches you, you quickly duck down and crouch in the lower half of the cupboard. As long as Snape doesn’t try to return the container, you should be safe in here.

Snape reaches you and closes the door, leaving you in darkness. You wait to hear Snape walk away, but you don’t hear any footsteps. Instead, the only sound is that of a long intake of breath. It’s almost as if Snape is trying to sniff you out. The cupboard door opens again and you see Snape standing in front of you. His eyes move along each shelf, looking for any absences. You’re happy that you haven't had the chance to find any ingredients you need so that Snape doesn’t realise you’re here.

Snape’s eyes drift down to your hiding spot. It’s almost as if he’s looking directly into your eyes. His nostrils open again as he sniffs the air.

“A Disillusionment Charm”, he says softly. “How sweet.”

Snape takes his wand out of his pocket and waves it. The cool feeling of the charm trickles away. You know that you’re now visible and Snape is actually looking into your eyes. Rather than be angry and yell at you, as you expect, Snape just smiles. It’s nearly as bad.

“Potter”, he drawls. “What an… honour… to have you here.”

“It’s not what it looks like”, you say inanely.

“So, you’re not about to tell me that you came here to steal some ingredients to make a potion that’s completely out of your skill range?” Snape retorts.

You wisely decide to keep your mouth shut. Snape’s smile widens as if you’ve just confessed all your sins. He grips your arm in a tight hold and pulls you out of the cupboard.

“You’ve had the run of the castle for too long”, Snape says. “I think you deserve a punishment.”

You let out a sigh of relief. Detention is an easy thing to deal with, even if it is with Snape. As if he’s reading your thoughts, Snape continues.

“Detention has never worked on you, Potter. I think something else is needed to keep you in line. Your Muggle family are probably too soft on you. I think a thorough spanking is what you deserve.”

You open your mouth to protest – primarily that the Dursleys have ever treated you well – but you close it again before you say anything. You don’t want to make this situation worse. Snape nods his approval.

“It’s already working”, he says.

Snape drags you over to the desk. He sits in the chair and pushes you so that you are lying on his lap. Before you can protest, Snape yanks down your pants and underwear. He could’ve just pulled them down to expose your ass, but Snape has decided to humiliate you more by pulling them down to your ankles. His hand caresses your ass and you shudder at his cold touch.

“I want you to count the smacks”, Snape says, his voice not betraying the slightest pleasure at seeing you in this position. “Otherwise, how will I know when to stop?”

Snape’s hand vanishes. You wait for the blow, but it doesn’t seem to arrive. You think that the trepidation will kill you.

SMACK!

The first spank catches you by surprise. The blow is harder than you expect and you think your right ass cheek now has a red mark on it. You yelp and almost forget Snape’s previous order.

“O-one”, you stutter.

SMACK!

This blow comes to your left ass cheek, giving it a matching impression. You close your eyes tightly to stop tears coming out.

“T-two.”

SMACK! SMACK! SMACK!

“Three. Four. Five.”

Snape alternates his spanks to make sure his attention is spread across your ass. By now, you realise that this punishment isn’t going to be as easy as you hoped. However, you notice another effect. Despite the pain from the blows, you feel your cock begin to harden. You hope that Snape doesn’t notice.

SMACK! SMACK! SMACK! SMACK!

“Six. Seven, Eight. Nine.”

You wait for the tenth blow, but it doesn’t come. Instead, you feel Snape caress your ass again. This time, his cool touch is welcome against your burning skin. Snape’s fingers slide between your ass cheeks and move over your asshole. You manage to suppress a moan, but you can’t stop your hole from twitching at the touch. You think you may have heard Snape snigger, but you can’t be sure.

Snape’s hand slides down over your balls and wraps around your hard cock. You begin to blush until your face is the same colour as your ass.

“Enjoying yourself?” Snape sneers. “This is meant to be a punishment.”

He continues to stroke your cock slowly. It’s agonising for you, as it’s not enough for you to cum. You squirm in Snape’s lap, but he doesn’t change his pace. Snape moves his hand so that he strokes you from below, then resumes your punishment.

SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK!

By this point, you’ve stopped counting the blows and Snape is too busy focusing on you to care. Snape doesn’t stop hitting you when he feels your cock spasm in his grasp. He continues jerking you off until you finally cum with a moan.

To your horror, Snape doesn’t move his hand away and he continues to rub your cock. The feeling on your sensitive member is nearly more painful than the spanking. You try to move off his lap, but Snape places a hand on your back to keep you in place.

Finally, you’re reduced to a quivering mess. Snape releases your cock and wipes the fluids on your burning ass. Then, he pushes you off his lap. You slide to the floor and kneel there, waiting for the next phase of the punishment.

When Snape doesn’t do anything, you look up. He’s turned his attention back to his paperwork. He spares you one glance and frowns.

“Are you still here?” Snape asks. “Get out of my sight.”

You haven’t got the ingredients you need and your pants are still around your ankles, but you hobble to the door and let yourself out of the storeroom. In the corridor, you breathe a sigh of relief. After all, Snape didn’t give you detention. Now, you need to return to the Room of Requirement to plan your next move.
