Gemma Farley, Slytherin Prefect

Strutting into the room Gemma looked Harry up and down before commenting, "Daphne my dear, it seems you've prepared a fine sissy for me."

"Of course Gemma, it's always a pleasure doing business with you," Daphne added with a wink towards the older student, at the word pleasure.

Giving a small laugh the Prefect agreed, "Of course, your business propositions are always to my liking," she said while licking her lips and looking at Harry.

Gulping, Harry could only stand there and wait for the inevitable. After closing the door and walking up to her sissy pet Daphne spoke, "I've already broken in this sissy, so he know to follow orders properly." Gemma nodded for Daphne to continue, "He'll follow any orders you give him as long as they don't conflict with mine for the night," she stated. "I'll be in touch, thank you for the help, it was a delight to work with you."

Walking out of the room Daphne gave a waved saying, "Be a good sissy and follow Gemma's instructions, I expect to see you tomorrow," before closing the door.

Straitening up, Gemma walked over to Harry. She practically towered over him, his height of five feet and two inches to her height of five feet and nine inches. Running her thumb along his lips while cupping his blushing face she spoke, "Sissy, tonight you will call responded to any orders with a yes Mistress Slytherin, because I run the house behind the scenes." Harry recoiled at the thought of having to call the Slytherin Prefect Mistress, but was was unable to avoid following the order.

"Yes, Mistress Slytherin," Harry said, while grimacing in his mind. Smirking down at him she said, "Daphne reported that you're very good with your tongue sissy. You'll be getting more practice tonight."

Placing her robe on a desk, she walked over to the bed. She pulled down her panties with manicured hands showing off her hairless pussy and puckered asshole, before giving an order, "Sissy, come stick your tongue in my ass like the good slut you are."

Harry walked over and placed his hands on the Prefects ass, where he started to lick her asshole. "Mmmhhhh," she ground out, "That's such a good job sissy, I bet your going to make your master a very happy girl." Using her hand to she started to finger her pussy while Harry was eating her backend out.

Harry observed ass and pussy while eating her out, his tiny pecker was trying to get hard in his cock cage as he became incredibly aroused. Seeing this she shook her ass in his face, before commenting, "You like my asshole don't you sissy? I bet you just want to lick me with that slutty submissively mouth of your right?"

"Yes Mistress Slytherin!" Harry said, "I love your big ass! I want to lick your puckered hole with my slutty sissy submissive mouth!" saying what Gemma wanted to hear.

She groaned at the intensity of the cute little **** licking out her hole. Eventually the attention was enough for her to cum, drenching her the bed with girl cum.

Shaking, she said, "Sissy take off all of your clothes," before taking off her own upper clothes and skirt, leaving her nude. Once Harry had taken of the ordered clothes, she had cast a spell on him, making it feel like there was a cold wave in his ass, while he waited for his next instruction. "Now, lay down on the bed, face down," Gemma commanded.

"Yes Mistress Slytherin," Harry said and as he was told. The Prefect shuffled on the bed behind him, taking the Girl Cock Potion, until she was almost leaning over him. "Sissy, I'm going fuck your ass with my dick and your going to take it like the good submissive slut you are," was his order.

"Yes Mistress Slytherin," was all that Harry was able to say, before Gemma started to push her girl cock into his ass. Harry tried his not to moan and groan from the feeling of the dick being **** into his ass. While the slut under her was squeezing her dick with his hole, Gemma started to **** her temporary sissy's ass with her hands. She continued to be rough, as she pulled and squeezed the juice piece of meat. Harry moaned wantonly into her bed as his ass cheeks and hole were abused.

While getting into the groove of being dicked down prone bone, Harry accidently rocked his ass back. "Yes, Yes, YES!" shouted Gemma when she felt him rock. "Whatever it is you just did, do it again and don't stop!" was what she ordered. "Yes Mistress Slytherin," Harry said as he continued to rock his ass back onto the Prefects cock.

"Ohhhh, ughhhh, AHHHHHH!" were the only sound coming from Gemma as Harry was used like fuckhole. "Your the best sissy ever!" she shouted, "You'll be seeing me often slut, I want my girl cock in your ass from now on," she declared. "I bet you just want me to fuck you harder?! You want to be my personal tongue cum hole?! You want to be a submissive sissy that I dominate all the time right?!" was what Gemma was howling.

"Yes Mistress Slytherin! I want your girl cock in your ass from now on! I want you to fuck me harder! I'd love to be your submissive sissy that you dominate!" Harry shouted into the bed keening.

With one last shriek Gemma ordered Harry, "Cum With MMEEEEEE!!" as she came, squirting her girl cum into his ass. Harry, already highly aroused from the attention of her girl cock and the feeling of the Prefect pressing her body down on him spurted his load into his green cock cage.

Harry was so out of it that he didn't even notice Gemma getting cleaned up and dressed, the, "I'll see you later sissy", and slap to the ass was hardly even registered except for a, "meep."

By the time Harry came to, Daphne had returned to the room and was looking down on him laid out on the bed and covered in cum. She smirked, giving her own slap to his ass. "Potter, I see you had a good time. Gemma tells me that you were a good submissive sissy. She's definitely going to be giving you repeat visits," Daphne teased.

After reaching into her side bag, she handed Harry a leather cord with a snake on it. "Put this on, and do not take it off unless I tell you to. You don't need the mask right now, so hand that back to me," she said.

After Harry had taken off the mask and handed it to Daphne, he put the necklace on. He didn't seem to notice any differences and looked to ask, but Daphne beat him to it, "That necklace is charmed, so that no one else notices how much of a sissy you look like. It will hide your ass, tit, and long hair," she bragged. "I'll leave you to get dressed on your own, but come back here on Friday, as soon as possible, I'll have more business for you by then," Daphne told her pet, before leaving the room.
