Exhibitionism

Hermiona gasped when she read it. But the book doesn't give her time to comprehend it. Another text appeared, as if the book reacted to her disbelief.

We understand this can be shocking for you. But sex adventures have an unprecedented calming effect. You just need to keep your mind open. Your first assignment is: Masturbate in a semi public place. It can be common showers, changing rooms in shops or during the movie. Because it is your first time, there don't need to be people around. Just the place needs to be accessible to the public and you must be naked. When you complete this one, you get another assignment. Good luck and enjoy it.

Hermiona read it over and over again. Still cannot believe what she is seeing. It can't be right. She was not exibicionist, she couldn't do it. But on the other hand, she apparently was under stress lately. When she thought about it, it was quite some time since she had enjoyed herself. So why not try what the book suggested. Hermione decided to do it in the Prefect bathroom. Even if she wasn't one anymore. She still had access there. She reached for her pajamas, but stopped herself. Why put them on and take them off again in the bathroom. She stripped her school uniform and then put her bathrobe on. When Hermione reached the staircase to the common room, she took a deep breath.

“Don't worry you are doing nothing wrong. You are just going to take a bath. No one needs to know you are naked under the robe.” she told herself.

She must admit that walking to the bathroom wearing only a bathrobe was rather nice. Excitement started to fill her. Inside she filled the bath with various foams. Then she stood on the edge of the bath. Looking around checking if she was alone. To be sure she waved with her wand, golden shimmering on its end confirmed that she is alone. Not counting mermaid painting opposite to her. Which was empty for now. If she wanted to do it here without an audience, she should hurry up. Last deep breath and she started to open her robe. First she slid it from her shoulders. Her boobs popped into the open. Hermione gigeled, then she dropped the robe on the floor. Naked, she stood without moving. Hands on her side, as if she was presenting herself.

“Merlin's beard,” Luna gasped. “Did you know she has such a gorgeous butt?” She asked Ginny, without looking at her. Her attention was full on naked Hermione. Specifically on her buttcheeks.

“No,” answered Ginny. “I actually never saw her naked.” Both girls were hiding in a small alcove right behind Hermione. Between them and the rest of the bathroom was a strong privacy charm. Assuring that, they cannot be seen or heard. But they will see everything that happened in the bathroom. Which right now, is very naked Hermione ready to masturbate.

When she submerged herself in water. Lunna sadly gasped. “No don't.’ and reached with her hand, as if she wanted to touch that beautiful bottom. Ginny quickly held her, because Luna almost stepped through the privacy charm.

“Careful!” Ginny hissed. Then added “Look, I think she already started.” Both girls moved their attention to the sound spreading from the bath. Aroused moaning was echoing on stone walls and piercing their ears.

Hermione didn't lose time, she clearly needed this. Luna and Ginny were listening, as their friend pleases herself. Her moans started to affect them too. Luna was almost lost in arousal, since she saw Hermiona naked. Young Ravenclaw can't believe how hot Hermione looked just standing there. Overcome by lust.

Luna started playing with herself almost in sync with Hermione. It didn't take long and both came. Hermionas final moan echoed on bathroom walls and faded. Lunas were muffled by the charm of privacy.

“OH god,” Hermione gasped when she emerged from the bath. She leaned on a nearest pillar, her legs still weak from a recent orgasm.

“That was great.”

After she calmed herself, she took her discarded bathrobe. Not putting it on yet. She walked to the door, naked and wet. There she finally put the robe on, satisfied and smiling. Hermione returned to the Gryffindor tower.

Girls let her have a few days without assignment. Ginny has difficulties convincing Luna about it. Since she saw Hermione naked, young Ravenclaw wanted to strip her asap. Luckily Ginny managed to convince her that they need to take small steps. Otherwise, Hermione could end it.

“So what are you suggesting for the second assignment?” Luna asked.
