"Not only are your robes ripped off, they are also dirty, Miss Granger", said Professor Sinistra.

Hermione looked down and saw that her robes were indeed muddy and that a large stain could be seen on her lower belly. That was where Luna had rubbed herself on.

The Gryffindor didn't answer, and kept on following the Professor in the corridors.

"Did Miss Parkinson do this to you? I saw you talking with her in a very heated way in front of the castle." asked Sinistra with a knowing look.

"No, Professor, she didn't. I'm so sorry I got into trouble again."

"It's okay, Granger. I'm not going to punish you for this time, you don't look well, and you're not even late after all. We're here".

"Thank you, Professor, thank you…"

"Good afternoon, students!" said Professor Sinistra as she opened the door to her class. "Today we will talk about Jupiter's moons. Sit down here, Miss Granger"

Hermione was surprised. The Professor was pointing at a chair behind the teacher's desk. She sat down under the bewildered looks of her classmates.

"Miss Granger just had a incident with her robes. She will sit here today in order for her not to endure further embarrassment. Now if you look at this map…."

Professor Sinistra started her lesson. From where she was, it was very difficult for Hermione to see the map on the board. But had it been a normal day, she would still have perfectly managed to understand what was going on in class. However that day was special, and her mind was paralyzed with fear. What if Pansy had found Luna? What if the Ravenclaw had told her how Hermione had milked her into her mouth? Oh no, no. That would be terrible.

Professor Sinistra went to sit beside her.

"Now please draw the moon's positions on your own personal maps. Take your time and pay attention to every details, precision a key notion in astronomy. Miss Granger, can you go and get me a quill in the closet, please? "

Hermione got up, and, for the second time that day, she heard the sound of fabric being ripped. She looked down and saw that Professor Sinistra's foot had stepped on her already torn up robes, and that with the movement of her standing up, it had been ripped even further. Now, Hermione's whole left leg could be seen entirely, up to her panties.

"Oh Miss Granger! I'm so sorry! Please sit back down, please sit back down!"

Hermione sat, angry, trying to cover herself but it was barely possible now. She didn't say a word, knowing that she would explode and burst into rage in front of her Professor and the whole class if she tried to say something.

Noone had raised his head from his parchment, except for Lavender, who was looking at Hermione interrogatively. She knew something was up, and Hermione gave a her a begging look, trying to make her understand that she needed help at the very moment. Yet, Lavender misunderstood it for something else, and looked down to her map again. Lavender had not spoken a word to Hermione in five months, since the day the Gryffindor tried to kiss her.

"I'm terribly sorry, Miss Granger. I'm going to get that quill. Please stay put" said Sinisra.

The Professor got up and went to get the quill. When she sat down again next to Hermione, she put a hand on her thigh. The Gryffindor shivered. She knew Sinistra had been too nice with her before.

The Professor's hand began to massage her thigh up and down. Hermione moved her leg in the opposite direction from Sinistra, but the teacher's gripped her stronger und pulled her thigh towards her again. The Gryffindor couldn't do anything, with her classmates all around. She closed her eyes, took a deep breath, and started drawing Jupiter's moons on her map, hoping that the class would end soon, and that Sinistra wouldn't push it too far.

The Professor's hand went higher on her thigh, and began to play with her panties.

"No" whispered Hermione. Lavender raised her head again, looking at them. She had heard.

Sinistra began to press one finger on Hermione's clit through her panties. Over and over again. Hermione thought about Pansy. She couldn't do that to her, she didn't want to cheat on her. First Luna had tried to take advantage of her, and now Sinistra. A tear went down her cheek, and Lavender saw it. Hermione looked down, trying to hide her face.

Sinistra's finger kept on rubbing her clit which, despite Hermione's despair, was getting harder with every second. Hermione felt that she was getting wet too, and didn't know how to make it stop. She thought about her love for Pansy, her anger for Luna, and her fear that the two of them would talk together. Yet, her pussy was pulsating, and it seemed that Sinistra had felt it too since she slipped her hand in Hermione's panties.

The Professor's hand began playing with her wetness and massaging her clit, circling with her finger slowly, very slowly, and Hermione held in a groan. How could she possibly be turned on in such a moment? How could she be turned on with another woman than the one she loved? Did that mean she didn't love her?

Hermione refrained herself from pushing her pussy into the Professor's hand, and kept still. The Professor was not putting enough pressure on purpose, she was just brushing her finger lightly on Hermione's clit, knowing that the student couldn't do anything about it. It was torture, and Hermione felt so guilty she wanted it to be over. She wanted to come right now, right here, so that Sinistra would remove her hand. Yet she couldn't come, not with so little pressure. She moved slightly towards the edge of the chair, to make Sinistra understand she needed more. But the Professor didn't change anything to the way she was touching her.

Suddenly, Lavender spoke up. Maybe she had understood that Hermione needed help, or maybe she was just bored with drawing Jupiter's moons.

"Professor. I'm sorry, but the class should have been over 10 minutes ago. We have already missed the beginning of our next period. Can you please let us go?"

Sinistra looked at her watch, and realized Lavender was right.

"You're right Lavender, everybody out! Have a nice day everyone! Don't forget your homework for next week!"

Everybody got up and started talking, running towards to door. Sinistra pressed her finger harder on Hermione's clit, and rubbed it violently, forcefully. It took a few seconds for Hermione to come with a muffled moan in the middle of her unobserving and noisy classmates. Only Lavender had seen it. She hadn't understood what had just happened to Hermione (she was miles away from imagining that something like that could happen in class, let alone between a teacher and a student!) but she knew something was wrong from the expression on Hermione's face, which had been sad, then exulting, and then sad again. She came up to the Professor's desk, and Sinistra removed her hand from Hermione's panties.

"Are you alright, Hermione?" asked Lavender. "You don't look well. Do you want me to accompany you to the Gryffindor Tower and change your robes? Hagrid will understand if we don't arrive to his hut right away. You can't go to class like that"

"Thank you, Lavender. I will come with you."

Hermione got up and tried to hide her leg behind what was left of her robes. She looked at Professor Sinistra, who was nonchalantly smelling her fingers looking at her. "Have a good day, Hermione! And you too Lavender! I'll see you both next week!"

Hermione followed Lavender out, and immediately after she left the room, burst into tears.

"What is happening to you, Hermione? " asked Lavender, concerned.

"It's nothing, it's nothing, Lavender. Please let's go to the common room. Thank you for going with me."

"Well, I knew something was wrong with you. From the way you looked at me. Is there anything I can do?"

"Just take me to the common room, and walk in front of me. I don't want people to see me like that".
