Hermione felt extremely tired after that day of work. This year she was Head Girl and she had to deal with and prepare the assignments of all the Prefects. Of course the Head Boy helped a lot, but dealing with a bunch of Slytherins was a hard task for her to handle. So she created this habit of going to the Prefects' bathroom after curfew – when everyone had already gone to bed – and taking a relaxing shower just before going to bed.

She entered the bathroom and placed her bag on the bench. She looked around and saw another bag next to hers. She felt a little crestfallen that she had to share that moment of privacy with another person, but that had to be the way to go.

It was only when she got closer that she heard water running in one of the bathtubs. It seemed the other girl – she couldn't see or hear her because every individual bathtub had shower curtains around it -- was in the second tub from the right, so Hermione decided to go into the first one.

She undressed and placed her clothes next to her bag. Kneeling next to the big, square bathtub, she opened the tap slowly, trying to not disturb the other girl. When the tub was filled, she entered and felt the hot water warming her body. She then sighed and went silent, enjoying every minute of her therapeutic program.

What she didn't expect was the other girl's voice speaking. No, not speaking, moaning! Hermione gasped and silently hoped that was only a certain sound that expressed the girl's contentment. Unfortunately for her, it was not.

The girl continued groaning, probably thinking no one was hearing her. Hermione tried to cover her ears with her hands, but the girl's voice was unavoidable. Hermione didn't even think about leaving because it would make too much noise and that would humiliate the girl, which Hermione didn't want. So she sat quietly in her bathtub, going underwater a few times to see if, when she surfaced once more, it was over.

Hermione didn't know if it was a Prefect or not. As far as she knew any of the Prefects could have given the password to another person. She just hoped it wasn't someone from Gryffindor or she would have to confront her every day. Hermione hid her face in her hands in shame.

After a few minutes, Hermione realized the girl had no intent to stop what she was doing. Whatever she was doing.

Probably touching herself.

Hermione slapped herself mentally after thinking these words. She blushed immensely because she had never thought about it or done it. It wasn't like she was against it or thought she would go blind if she did it. She just didn't have the time, the patience, or the intimacy.

However, she couldn't stop wondering whether it really was that good. The other girl seemed to be enjoying herself a lot, while she was still embarrassed by the sounds. Hermione liked logic, and if she thought about the cold logic of this situation, the direction her mind took was to enjoy the moment. Yet, her shyness was blocking her from taking pleasure from her body.

She tried to hear her neighbour more intently. But as she concentrated, she began to hear something she hadn't expected to happen so soon, as she was trying to enjoy the moment.

The girl was orgasming.

She heard her quick breaths and soft groans, followed immediately by a loud moan. That last sound made Hermione bristle, while she bit her lip. She never knew an orgasm could sound so exciting and pleasurable. She just wished the girl would continue.

But she just heard some splashing in the water after the girl was finished, and Hermione felt a little disappointed. She hoped she could listen to the girl's voice again to feel the excitement she was starting to feel just before it was all over. Hermione whined a little too loudly, and that provoked something she was not expecting.

"Is somebody there?" the other girl asked with a confused voice.

Hermione gasped and shut her mouth with her hand. Her mind twirled with fear from what the other girl could think.

"Yes," Hermione finally answered.

"How long have you been there?"

"Long enough," she answered, without thinking.

There was a long silence and Hermione expected the girl to come out of her bathtub to confront her. However, she could not even hear the water splashing.

"Did you have fun?"

"What?" She had heard perfectly well, though. She just wasn't sure she wanted to answer.

"If you had fun hearing me touching myself."

"Well, I…" Hermione wasn't sure. She hadn't had the time to have real fun.

"Did you touch yourself?" The girl's bold questions were unbelievable.

"No." Then she decided to enter the game she was being challenged to. She never refused a challenge. "I didn't have time."

"You have time now."

A heavy silence fell on the bathroom.

Hermione wondered seriously if she should do it. She had never shared this kind of intimacy with someone. Well, at least the girls were unknown to each other.

"Will you try to see who I am?"

"For you to spread across the school I shared my private moment with you? No, thanks," the girl said, almost angrily.

She was right. Hermione didn't need to worry because the girl didn't want to be humiliated. Not that she would do it anyway, Hermione had morals. Hermione for a moment wondered whether the girl could identify her voice. However, the hotness of the water was making her voice huskier and maybe that disguised it a little.

"I'd like you to describe what you're doing."

Hermione's cheeks turned crimson. She wasn't sure if she was ready for that.

"I don't know if I can do it."

"Touching yourself or talking while doing it?"

"Both," Hermione admitted.

"It's easy, I will help you."

Hermione's mind exploded at what those words could mean. For a moment, her eyes filled with visions of the girl coming next to her and teaching her how to touch herself. However, as no movement was made from the other side, Hermione relaxed.

"First rub your nipples with your fingers."

Hermione lifted her hand and started to do exactly as the girl told her. Warm sensations that made her shiver hazily spread through her body. She felt her nipple getting hard and her breasts becoming pointy as she continued to touch it. She never thought it would feel that good. Instinctively, she started making purring sounds and mewling. She bit her lip and released a grand moan as she pinched the nipple. Hermione didn't know why, but she thought she was actually good at this.

"You seem to be enjoying my idea."

"Yes..." Hermione howled.

"Now touch your clit." The girl's voice was hoarser than before. "I'm rubbing it right now with small strokes with my thumb and it feels great."

Hermione didn't know she was doing it, too. Somehow it made everything more exciting knowing they were sharing the same moment. As she felt an ache between her legs, it led her to thinking she never knew she could be turned on so much by a girl. She always thought she was into boys. Maybe it didn't matter. Maybe she liked them both. Maybe it was because before a gender, there was a person.

"I didn't know you were touching yourself too." Hermione did as she demanded and started stroking her clit at the same time she continued to rub her nipple. She immediately felt the pleasure that travelled through her as she shivered. She panted and groaned loud enough so the other girl could hear. "It's so good."

"I know. Now fuck yourself." The girl liked being the authority, that was for sure.

Hermione understood that she should insert her fingers inside her. The thought of doing it made her belly tingle and the anticipation made her legs compress. Her fingers began to lower from her clit to her entrance, while she caressed her lips. She couldn't believe she hadn't tried this before. It felt so unbelievably good, even sharing it with someone else. Or maybe sharing it was what made it so much better. She could hear the other girl's moans once again and she imagined a naked body thinking of her just two curtains away.

She entered with one finger inside and started immediately stroking up and down. She felt what must have been her G-spot and her hips bucked when the feeling spread in her body. She inserted two fingers and, still rubbing her nipple, she felt how wet she was inside. She could feel a great sensation as she fucked herself. At the same time, she could hear the other girl panting and reaching her climax. Obviously she was more skilled than Hermione and was used to getting there faster.

"Are you coming?" she asked between heavy sighs.

"Almost." She stroked herself faster and opened her legs to allow better movement. She touched herself more ardently as she heard the other girl's voice "Talk to me."

"I want you to fuck me. I want to lick you and your wet cunt to see you flushed for me."

Hermione arched her legs and felt herself tightening around her fingers while her nipple was harder than ever and her teeth bit her lower lip. As she heard the other girl's words she couldn't help but feel a divine pleasure rip through her. Her voice was so sexy.

"Fuck, I want that too." And with a final thrust, Hermione thrust her hips up and orgasmed against the bathtub while she only saw white.

When she recovered her senses, Hermione thought about what she had just done. She hadn't regretted it, but she felt a little weird. It was her first time touching herself and she had shared that moment with someone else she didn't know. She opened her eyes and only saw fog around her. She felt divine.

"I never did that before," Hermione said, shyly.

"Well, there's a first time for everything."

"Had you done it before?"

"Yes." Silence. "But you were better than the others."

Hermione was surprised. "Why?"

"Because, the others usually warned me first that they were listening." She giggled. "But since you had never done this it was more thrilling and the sounds you made were very peculiar."

"Peculiar?" Hermione was scared she had said something stupid.

"You just moan a lot."

"Is that good?"

"It's great, don't be so insecure."

"Okay then."

There was a long silence while Hermione heard the other girl play in the water.

"Do you want to know what the others usually say after we finished?"

"What?

"They always told me to join them."

Hermione's mind raced. She didn't know if she was prepared to face the girl she had shared so much intimacy with.

Oh, wait, maybe that's the right thing to do.

"If you're not comfortable with it that's fine. Since it was your first time and all I'm sure you're very confused and all that." She seemed a little annoyed.

"Actually, from the course of things I think you're right but…"

"You think I might be ugly?"

"No!" Hermione cried.

"Then you're scared."

"I'm not scared!"

"Prove it."

"Okay, come here then." An instant after she announced this, Hermione made a mental note that she should learn how to be less of a Gryffindor and learn how to decline challenges.

She heard the curtains being dragged apart and a few steps on the floor's ceramic tiles. Her heart was racing and her veins were thumping inside her. She thought she couldn't get any more nervous than this when the other girl opened her curtain and she saw who it was.

Pansy Parkinson.
