Chapter 23*: Chapter 23 – Sinistra

That night was most disastrous. Ron ate chocolates sent by Romilda Vane which were meant for Harry. He knew this was her idea of him becoming her boyfriend, but he ignored them. Vane was just a sex toy to Harry and he had no interest in dating her. Ron, on the other hand, had eaten the whole box and became obsessed with her.

After saving Ron's life, Harry and his friends visited Ron in the hospital wing, concerned about him. It was clear to Harry that he was gonna be there for a while. What's worse, Lavender has been hounding him about Ron and McLaggen had been doing nothing but talking to him about him as Keeper. It was disastrous.

The Dormitory that night was all a buzz about what happened to Ron. Some say Slughorn hated him and wanted him dead, some say it was an accident, some gave stupid explanations that Harry didn't understand. While up in his room, Hedwig came to his window and tapped. Harry opened it and saw she was holding a letter. He paid her and sent her off to the Owlery for the night. Harry opened the letter and read it to himself:

Dear Mr. Potter

I have urgent news to discuss with you about your… after school activities. Meet me outside the Astronomy Tower tomorrow night after your Quidditch practice. Don't be late.

Professor Sinistra

He wondered why Sinistra would send him an owl and want to talk to him. Sinistra was the Astronomy teacher and somewhat strict. She never showed any kindness or generosity to Harry, but there was something about her that he liked. He kept it in the back of his head until it came.

After practice the next night, Harry read the letter again and decided to go to the Tower. Upon arriving, Professor Sinistra was at the door to the classroom, arms crossed. He knew he must've been late, but he tried not to look guilty.

"Evening Mr. Potter. Follow me." they walked and talked. "I bet you are wondering why I have called you here this evening."

"Actually, I was just concerned that this is some nightly detention."

"You have done nothing wrong. Although, you will be soon."

"How do you mean Professor?"

"The rules state that a Teacher/Student relationship is prohibited, but I tend to break those rules every so often."

"Huh?"

"Sex, Mr. Potter. It is against school rules for a student and teacher to engage in sexual activities."

"Never knew that."

"Indeed. But this evening, we are going to break those rules." his heart jumped.

"But Professor… why?"

"I hear things about you fucking all these girls. You seem to be very good at it. I want a taste of it. My husband hasn't pleasured me in years. I need someone younger and better."

They stopped in front of a wooden door with an S on it. She opened it and they were inside her very own bedroom, with the books, papers, and a comfy looking bed. The covers were off and Harry grew nervous. He never had sex with a teacher before and in the back of his mind, he knew it was gonna be good.

Sinistra put down her wand. She stepped toward the bed and removed her night gown, revealing her naked black body. Her boobs were a solid C, which was weird because she always looked like a B. It was like Angelina all over again, but with someone older. She sat on the bed, looked at Harry and seductively had him come over. As he walked, he began thinking if this was right. His lust made him think it was more than okay,

When he got to her, Sinistra undid his pants and was shocked by how big he was. She took his member in her hand and stroked it, feeling as much as she could. He moved forward and she began licking his cock, enjoying his youth as long as possible. He had never fucked a teacher, but it was feeling really good.

Inserting it into her mouth was comforting for Harry, who instantly moaned as she sucked on him. He closed his eyes and enjoyed it. Harry could feel his essence being sucked out of him by his very own teacher and it was amazing. After a few minutes, she took it out and climbed onto the bed, and eventually reaching the pillows and laying on her stomach. She rose her ass high in the air and spread her pussy lips.

He climbed up to and scooted to her, thrilled to be fucking her cunt. His hand cruised her cheeks and it felt so smooth. Harry squeezed them and slapped her ass, which made her laugh. After hesitation, he quickly entered her, giving her a new experience. Fucking this older woman felt great, like when he had sex with Molly. Her insides felt so warm, like a cozy bed.

"Mr. Potter… fuck me good."

"Yes ma'am."

He started thrusting in and out of her, giving her an excuse to curse. Harry held onto her sides as he pounding shook her body. He looked over and could see her tits jiggling back and forth. Harry could also see her biting her lip and giving silent moans. He knew this was a sign he was doing good, so he kept at it.

The longer he was inside her, the louder she got. It wasn't long before she was grasping the sheets and cursing like a sailor. The fact that his teacher was using all this language in one moment amazed him. He spanked her again and this set her off. She demanded he got his best and he pounded her faster and harder, which was enough to make her scream.

After a few more minutes, he could feel himself about to come, so he took it out. When he asked her about anal, she said she never liked it because it hurt her way too much. Sighing, he decided to fuck her again while on top. She laid down, her tits facing him, and she spread her legs, awaiting the young stud in her bed.

He closed in on her and thrusted deeply inside her. She moved her head back and grunted, revealing she was liking it. He grabbed her legs and felt them before plopping them on his shoulders. At first he went slow, as to preserve the moment. He bent down and kissed her for the first time, planting his tongue inside her mouth.

As they kissed, her legs dropped and she wrapped them around him, keeping him inside her. He released from their kiss and focused on her jiggling tits. His arms clamped down on hers, pinning her to the bed. The feeling of her tits being pleasured was of greatness to her. He then began pounding her harder and faster, but not a lot.

"Fuck Potter! That feels so good! Ah, FUCK! Fuck me! Fuck me!"

He got up from licking her nipples and looked at her. She had beautiful eyes and a generous smile. Smiling evilly, he thrusted even harder which made her yelp in pain. This didn't stop her from spilling every curse word in existence. He knew he was close, but he kept on going. Lust was in control and it wasn't a coward.

"God! Come inside me Potter! Come! COME!"

With one all mighty final thrust, his manhood exploded inside his teacher, filling her up with his seed. Squirt after squirt made her moan in pleasure and it seemed endless. After the sixth squirt, he collapsed on top of her and was tired as hell. Sinistra stroked his hair and kissed his forehead.

"Mr. Potter, you were fantastic!"

"Really?"

"Quite. My husband doesn't fuck me like that ever!"

"Thank you. Just by curiosity, did I get you pregnant?"

"Gotta wait a while before I can answer. But is so, it was worth it for a night with you."

"Great," he said. "Let's not tell anyone, okay?"

"Deal. This doesn't mean I'll go easier on you in class, Mr. Potter."

"Fun," he said sadly.
