Harry Sees her, and Follows Daphne

At the end of the day Harry went up near the library like Daphne ordered. It was easy to escape scrutiny from the rest of the Gryffindor's of his year by saying he just wanted to explore the castle a little by himself. Walking near the library, he saw Daphne at the end of the hall. She smirked at and made a small gesture with her hand to follow her as she walked away from the main corridor.

Having **** but to follow her, Harry keeps walking even as they get farther and farther away from the well traveled areas. As she was walking Daphne was periodically casting a spell. Finally she stopped near one door and waited for him to catch up to her.

"Good evening pet," she commented, waving her arm towards the abandoned classroom while opening the door she spoke, "Every Friday, Saturday, and Sunday after the end of the day you will come to the classroom and wait for me if I am not already present."

When Harry didn't say anything in response, Daphne shot him a disappointed look, "When I say good evening or good night you will respond Potter," she declared.

"Good evening Mistress Daphne," Harry was **** to say.

"Better, but don't make me remind you again," she added with a look. Daphne waved her wand around the classroom removing all the dust. Waving it a couple more times, she was able to close the blinds, lock the door, and silence the room.

"Tonight we will be practicing for an assignment I'll have for you later," she said, sounding ominous to Harry.

Daphne used a spell to move all of the desks in the room to a corner before bending over to get something out of her side she had brought with her. When she bent over Harry was able to see her skirt lift up a little showing off her panties and ass. Standing up she smirked at Harry, "Tell me how much you enjoyed that little show pet?" she questioned.

"I liked your show a lot Mistress Daphne," Harry answered entirely honest, and sounding embarrassed about it.

Laughing a little she used her wand to levitate something out of her bag, surprising Harry as a whole bed was pulled out.

Looking at his nervous face, Daphne gave Harry what he thought was reassurance, "Don't worry Potter, we wont be having sex right now." He relaxed just a little hearing that.

Placing her bag on the bed she plucked one flesh colored potion from it and placed it next to the bag.

"The main event approaches pet, try to learn as much and as quickly as possible," she ordered. Standing up, she said, "Come over here, in front of me and kneel."

Harry did as he was ordered wondering what was going to happen to him.

Giving him a heated look, she smirked down at him, before turning around and bending over to slowly pull down her panties. Harry was almost getting excited, he was able to see Daphne's hairless pussy up close.

Getting a grip on his hair with one hand, she told him, "Don't worry pet this is the best part," before downing the potion she had with her other hand.

Daphne moaned soon after, and due to his proximity Harry was able to see something forming right above her pussy. At first he couldn't make out what it was, but then he realized that she was growing a cock. His shock only increased as it continued to grow blowing his three in penis out of the water reaching a staggering nine inches.

Sniggering, while stroking her new penis with the hand not in Harry's hair she said, "See something you like pet? Don't worry, you'll get use to seeing a girl cock regularly real soon."

Harry went to question what she mean, opening his mouth to ask, but before he was able to Daphne had started pushing her girl cock in his mouth. "Start sucking on my penis Potter, use your tongue, swirl it around the head and bob up and down," she ordered.

Involuntarily, Harry started to swirl his tongue around the head of Daphne's girl cock while sucking and bobbing up and down on. He was blushing up a storm, while she was moaning out to him, "Ohh, that's a good slut. You must have been born as a cock sucking sissy to have these skills."

She grabbed onto his head with hand with both hands and started to slip her penis further into his mouth. "Potter, you are such a whore, you don't even have a gag reflex," commented Daphne as she groaned and was able to push more cock into her pets mouth pussy.

As she began picking up the speed she was thrusting into her sluts mouth, he started going, "gluck gluck gluck," as he deepthroated her girl cock.

Finally shoving her penis all the way down her sissy's mouth Daphne was able to feel his lips moan around the base of her cock.

Pulling her girl cock out her pet's mouth, she slapped him on the face with her cock as he tried to recover from being out of breath. With her penis flopping on his face she commanded him, "Pet! Tell how much you love to gobble my girl cock like the sissy slut that you were born to be!"

"Mistress Daphne! Ohh, Mistress," Harry moaned trying to get his breath back still, "I love being born as a sissy slut that gobbles your girl cock!"

"Good boy, now I'm going to fuck that throat pussy of mine so hard!" she shouted while sticking her whole cock down his mouth in one go. Daphne only speed up continuing to throat fuck her pet faster.

"Gluck gluck gluck gluck gluck," Harry continued to moan as Daphne fucking his face, spittle and pre-cum dripping all down his clothes and face.

"That's it pet, I'm almost going to cum, when I cum down that throat of yours, your going to cum as well," Daphne ordered.

"Ohhh, uhhhhh," she moaned as she held his mouth to the base of her cock as she pumped her baby batter down his gullet.

When she finally finished depositing her load in the stomach of her slut she pulled out and let go of his head causing him to fall over leaving him face down ass up.

After drinking the antidote to the Girl Cock Potion, Daphne pulled her panties back up and gave her slut a slap on the ass. Relishing in the eep he let out she gave him a final order before leaving for the night. "I might not be alliable every night your here, incase I'm occupied I shall leave you with instructions on what to do, see that you follow them," she declared before leaving.
