During the next transfigurations class as the class was leaving Harry was stopped.
"Harry Potter!" Professor Mcgonagall had her arms crossed. "Is there something wrong Professor?"
"Oh what a load of crap Harry. You have just earned yourself detention with me" Harry was surprised.
"but Professor..." "No buts Harry to my office now!"
Harry follows Mcgonagall to her office his head down the entire way. After arriving Harry sits down. " Mr. Potter now give me your wand I will give it back after your detention." Harry reluctantly hands it over "Now you sit here and think about telling me the truth of what happened and I will be right back" Mcgonagall proceeds to walk into her bedroom which is attached to her office. Harry sits there and thinks "oh what the hell am I supposed to say?!"
Little to Harry's knowledge professor Mcgonagall had gotten extremely wet thinking about what she knew Harry had done and she had gone in her room to change but instead stripped and started daydreaming about being her instead of Molly Weasley. She suddenly remembered she had Harry's wand and picked it up out of her outfit on the floor. She then comes up with a terrible wrong plan but it felt so good and so right. She decides to unlock and slightly open the door so Harry would not notice at first. She would then start to play with herself again. She would slowly build up the volume of her moaning until she new Harry would come looking. She knew she would have him then.
Mcgonagall decides to carry through with her plan. She just needed to have Harry. Badly. She proceeds to quietly open the door a little and then goes back to her bed. She begins to play with herself moaning louder every moment.
Harry while outside keeps hearing noises come from her room and is completely clueless as to what is happening. He then very clearly hears a loud moan and his name come from the room and jumps up and walks towards the bedroom. He sees the door was left open a little so he peeks in. He cannot control his shock when he sees what is happening. Especially when he notices her pussy!
He ends up opening the door a little more to try and get a better look and ends up falling into the room onto the floor. "Glad you could make it Harry" Mcgonagall smiles. She takes her fingers out of her pussy and waves his wand at the door and it closes and locks behind him. "Professor what the hell is going on." "Harry isn't it obvious? I want what I know you did to Molly and now with Sinistra, Mrs. Granger, Greengrass and Delacour. I want you to make me feel young again!" She sticks her fingers back in, spreads her legs wider for him to see, and starts to play with her medium sized boobs. "Let me put it this way if you do not do this for me everyone will know! Now fuck me! And please call me Minerva" She yells
Harry smiled walks over and kneels in front of her and starts pushing his own fingers in and out for her and starts to lick too. "Oh yes Harry make me feel young again! Lick me baby!" Harry moves faster and licks faster. Shortly after Minerva squirts all in his face. "Am I done now Minerva?" Harry joked. "Merlin no we are barely started!" She shoves Harry onto his back and strips him. She marvels at the size of his dick. "My my Harry this looks delicious!" And with that she started to bob her head up and down on his member. After at least 15 minutes she stops.
"I need you in me Harry." She gets on top and slides him right in making Harry moan and nearly causing Minerva to scream since it had been so long. "Oh how I have missed this" Harry horns appeared as he started to move his hips in unison with her bouncing. This caused a big smile from Minerva. "Glad you could join me mr. Potter!" After awhile they both end up releasing at the same time. Minerva got horns and Harry's mark.
"Now mr. Potter that is how you serve a detention. Go on back to your dormitory. But also I would love try again some time" she winks. Instead Harry flip them and kiss his teacher. She didn't fight as Harry fuck his eight wife.
