Encounter in the back alley

As the three girls walked to the Hogsmeade. Slight wind tickled Hermione's crotch and butt.

It wasn't strong enough to lift her skirt. But it was enough to keep her on edge. As the breeze moved between her legs, slightly touching and tickling her bare pussy.

In this situation she can barely follow what her friends ware saying to her. But Luna and Ginny didn't seams to worry about her not paying attention.

When they arrived, Hremione noticed that there were not many people in the streets. Mostly locals and few students. Which was lucky.

With the girls holding her hands. It would be difficult to keep her skirt in place. But with so few people around, it may not be necessary.

There will still be the possibility she will flash someone.

But right now she didn't care. Hermione even eagerly waited for the opportunity to show someone her bare butt. Even if the tought makes her blush like crazy.

After she spent all week without underwear. She somehow started to enjoy the feeling. The possibility of being caught. Makes her tingle in the right places.

All three girls wandered aimlessly through the streets.

Ginny and Luna looking for an opportunity to expose Hermione. Without her knowing about it.

Both girls exchanged knowing stares.

From Hermione breathing and her flushed cheeks. They suspect that she is starting to be aroused.

To distract her they started to talk with her even more.

“So how is that book?” Ginny asked suddenly, when they passed two older wizards.

“Book?” Asked Hermione as she was looking over her shoulder. Praying that the two men didn't look back. She feared they would somehow realize she's not wearing underwear.

“Yeah, from McGonagall. “ continued Luna.

“What is it about anyway.?” Ravenclaw Witch asked as casually as possible.

“S-Stress..,” stuttered Hermione as a light wind touched her pussy. “How to manage stress.” She answered between two deep breaths. Trying to calm herself.

“Great, you needed it.” Said Ginny.

All three turned to the right. Now looking on main street in Hogsmeade. Behind them was one of the backstreet, leading from the main to the smaller streets behind the houses.

What Hermione didn't notice, but Luna did. Was a Hufflepuff student walking from the backstreet, towards them so far, he didn't sees them because he was looking into the ground.

As he approaches Luna waved her wand.

The Beck of Hermione's skirt started slowly levitating, exposing her pale butt.

Because the spell was gentle, Hermione wasn't aware of it.

For now, Luna was the only one seeing Hermione's bare bottom.

And even she sees only the curve of her butt from above.

If she didn't want to alert Hermione to her state of undress. She must be satisfied with the view she had for now.

Finally the Hufflepuff student realized that someone was blocking his way. He raises his head. And the first thing he sees was pair of beautiful bare buttcheeks.

He immediately started blushing. Even more when he looks higher and he meets eyes with Luna.

She was smiling mischievously, with her finger on her lips in a shush gesture.

Hufflepuff boy not knowing what to do. Decided to run.

“Damn what is his problem,” gasped Ginny when the boy ran between her and Hermione. Which causes them to stop holding hands.

Hermione looked after the running boy with confusion. When she felt a slight breeze on her beckside. This time it was different.

She clasped her hands on her butt. As her palms meet with the skin of her cheeks. She realized that the boy must have seen her exposed bottom.

She gasped.

“You all right Hermi?” Asked Ginny.

“Yeah,” answered Hermione with her hands still on her butt.

“How about we go to Three broomsticks?” Suggested Luna.

“Good idea, I need to go to the bathroom” said Hermione and quickly adjusted her skirt.

Once Inside, Luna and Ginny go find an empty table. And Hermione headed to the bathroom.

She needed to lose some steam. Whole week going commando. The anticipation of being seen. And now that last encounter, makes her aroused beyond limit.

When she reached the bathroom , her hope for a quiet place to play with herself disappeared.

In front of the girls toilets were long queues.

Then she noticed the door leading into the back alley.

In her clouded state of mind she doesn't hesitate.

When outside, Hermione doesn't even check properly if she is alone. She lean against the wall.

Then put her forehead on the forearm, with which was leaning on the wall.

Her back curved slightly which caused her butt sticking out. With her free hand, she rolled her skirt all the way up. Revealing her buttcheek to the back alley.

No longer caring if she will be seen. Deep inside, she even hopes that someone will catch her in this situation.

“Finally” Hermione gasped when she started to masturbate.

First she was surprised how wet she was.

But any thought was soon replaced with waves of pleasure. As her fingers massaged her wet pussy.

She was approaching climax when something hit her in the back. She felt something washed over her body. And then she realized what it was, but it was too late.

The spell holds her tight. She cannot move a mussel. She can't even speak.

“Well, what have we here.” Man's voice asked. From behind her.

“I usually catch some boys trying to sneak peek into girls' toilets. But this is new.”

Unknown wizard said and approached her.

“I must say I like this better, than some peeping Toms.”

Hermione felt his presence, he stood right next to her. With the spell holding her tight, she can look at him. She could look only to the ground. Man continued talking.

“By the uniform I judge you are a Gryffindor. In my time at Hogwarts girls didn't wear such revealing outfits.”

Then Hermione felt his hand gently cupping her left buttcheek. Mix of arousal and fear washed over her.

He squeezed and cupped her cheek and then slapped it.

SLAP

Hermione whimpered. That was the only thing she could do.

“Beautiful. '' said the wizard and put his hand under Hermione's bluse. Couping and squeezed her left titt.

“As I thought,” he said and continued playing with her niples. Listening to her moaning.

“And last thing,” he announced and moved his hand from her boobs to her crotch. Which was partially covered by Hermione's hand.

Another moan escaped her lips, when he traced his fingers around her wet pussy.

Then his hand was gone and Hermione heard sniffing.

“You must be close” the unknown wizard said, “ like a proper Gryffindor slut.”

Hermione wanted to protest. But only thing escaping her lips ware moans and whimpers.

“I would like to play with you longer, my slut.” Said the wizard suddenly, patting her buttcheek again. “But I must go. See you next time.”

Hermione was happy it was over. Even though she somehow enjoyed it. But she was glad he didn't see her face. So he will not recognize her if they meet again.

As if he was reading her mind, he added “OH and one last thing. Because I couldn't see your face. Which I hope is as beautiful as your butt. This would help me to recognize you next time.”

With that said, Hermione felt something pointy touch her left buttcheek. Then she gasped as some stinging sensation moved over her cheek. As if tausend small needles puncturing her skin.

Luckily it didn't last long.

“With this mark, I will recognize you everywhere. Even if you will be wearing pants and panties.”

Explained the wizard and then he left. What Hermione couldn't see, was the word SLUT magically tattooed on her bum. When it faded off, the spell holding her disappeared too.

And with that she climaxed. As if the spell was holding her orgasm too. Not just her body.

Her knees buckled and she fell on earth. It was so powerful she couldn't even stand.

After she calmed herself. She looked down on herself. Asaid some dirt on her knees. Everything else looks fine.

She returned inside and found Ginny and Luna.

“Hermi, are you ok?” Ginny asked when she saw her. Hermione didn't want to explain what just happened so she just said.

“I think I ate something bad yesterday. I will go visit Madam Pomfrey.”

Without a word they accompany her into the hospital wing.

After Madam Pomfrey assured them it's probably just exhaustion, they left Hermione there overnight.

Hermione fell asleep as soon as she lay into bed.

She must be more exhausted than she thought. After all she experienced today it wasn't surprising.

Her thoughts were in the back alley in Hogsmeade. When she drifted into deep sleep.
