Hermione Granger

Hermione's intellect was marvelous. She was 19 years old, with enormous curiosity and an amazing memory. However, her willpower was weak, and that was something I could gladly exploit.

During the next class, as I was explaining, I walked around the classroom, and I used a subtle «Legilimens» as I went past Hernione, not to penetrate her mind, but to implant an idea: «I'm curious about sex»

When the class finished, she approached me. Hermione is a beautiful girl, although her long, curly hair might attempt to hide it. She's not exceptionally curvy, but I can see a gorgeous body underneath her uniform. She was blushing and panting lightly.

"Excuse me, professor. I was wondering if you could solve a doubt I have about... The charm we learned today."

"Absolutely, miss Granger. Let's go into my office." I invited as everyone else left.

"Oh, it... It shouldn't take long, I..."

"I insist." I smiled, stood up, and walked up the little staircase behind my desk to reach the teacher's room. Hermione gesticulated a little before nodding and coming me. I flick my wand and the door closes and locks behind her, although I do it so subtly the door doesn't even creak nor click, so she doesn't notice. "So, you were saying?"

"Yes, professor. You see, although I do revise my notes and read the book several times, I find it a little harder to... Make the movements of the wrist in time."

"Interesting, isn't it?" I sat on my desk while Hermione stood across from it. "How powerful magical effects still depend on the movement of our bodies. Let me see." I stepped forward, grabbed her right wrist gently and raised her hand a little. She sighed as I rolled up her sleeve and examined her forearm. Her skin was so soft, and I could sense her warm breathing. I couldn't help but smirk. "To solve that, you need some physical exercise, miss Granger."

"Physical?" She repeats with a nervous giggle.

"Yes, physical. Move your arm forward " I used my hands to position hers. "That's it. Close your hand as if you were holding a rod. Then, move your wrist up and down. This will exercise the muscles of your forearm."

"Like this?" She said, doing it the movement on her own. She seemed to realize it was a jerking motion, and she stopped slowly. "Isn't this movement a little... Suggestive?"

"What do you mean, miss Granger?" I stepped back and sat on my desk while Hermione kept on doing the «exercise» "Are you thinking about something beyond mere academic practice?"

"N-no, absolutely not, professor! I..."

"Because I am."

I tapped my clothes with my wand and made them disappear, showing my naked body to her. Hermione gasped as she eyed my large breasts jiggling softly, and my futa cock getting harder. Her face got completely red.

"P-professor! This is highly inappropriate! I-I should..."

"«Imperio»" I said almost sweetly as I pointed my wand at her. She immediately stopped talking, although the look of concern on her eyes remained, which I loved. "You will beg for this in time, but for now, you'll need some help. And as you can see, I need some help as well."

I twitched my cock, and Hermione followed my mental instructions: she knelt down and reached with her hand, grabbing my hardening cock firmly.

"Yes. Practice the exercise, miss Granger." I said with a smirk as she started stroking my futa cock under my command.

Her eyes were scared, but her body could do nothing but obey. Soon my cock got much harder and bigger. Watching her hand go up and down its length, barely able to surround it with her fingers, was so beautiful.

"Maybe work those lips a little." I ordered, and Hermione opened her mouth and gave my glans, which was already gleaming with thick drops of precum, a long kiss. I had her savor the head of my dick like a slut, and then I went deeper inside her mouth and down her throat slowly. "You're such a good girl, Hermione. You're brilliant, you're obedient, you'll be a very good sex ****."

I kept her going, sucking and jerking me off faster and faster. I kept her going until I shot my load without warning. She swallowed under my command as well. Those long shots of thick, hot semen passed down her throat without resistance. It was such a delight watching that pretty face gulp and gulp my seed down. It was a long, delicious orgasm, and she didn't waste a single drop of jizz. She cleaned my cock when I pulled out.

"Good girl." I had her stand up, then I pulled her in for a passionate kiss. I love feeling the taste of my own cum on other girls' mouths. "When you leave this room" I whispered in her ear afterwards as I tapped her temple with my wand, modifying her memory. "You'll just remember how beautiful and sexy I was when up close. You'll remember the exercise I taught you, and that you spent a lovely time with me. You can't wait to have another practice like this. You want it so bad. You desire me."

I let her go. I magically put my clothes back on, then I gently pushed Hermione out of the room with a hand on her ass. The moment she stepped outside, I dispelled the Imperius curse, and she sighed deeply. It took her several seconds to process everything. Then she turned around, blushing and giggling.

"This was so very enlightening! I'm looking forward to our next session, professor Decipia!"
