Harry decides to change the sisters one more time

Looking at the identical twins, Harry came to a conclusion. He was never going to let them go. They would be his forever. He wouldn't let them be anyone else's. In light of that, he decided that a few more changes were necessary.

"Both of you stand up," He said. After they had done so, Harry did as well. The twins stared at him curiously.

"What are you planning Harry?" One asked.

"I've decided to make a few changes to our relationship." Harry said, vanishing the mattress from beneath him.

"What do you mean?" The other questioned.

"Neither of you are my girlfriends anymore, you're my slaves." He said, staring at them intently.

"Absolutely, Harry." They said in unison. "We're happy to serve you."

"And you don't call me Harry, you call me Master." He added, his cock twitching again as he reduced two woman into his servants.

"Yes Master."

"Now, which one of you is Emilia, and which is Hermione?" He asked.

"I'm Emilia, Master," Said the one on the left. "She's Hermione."

"Wrong," Harry replied, "Neither of you is Emilia or Hermione. You don't need names, you're just my slaves, and because you're identical, you're completely interchangeable. Neither of you can even remember which one is which."

"Yes Master." His slaves said. He would probably forget which one was the real Hermione in a few minutes.

"Oh, and what I said earlier about you being the smartest witch of your age? You can forget that. You both know nothing except how to best please me." The two of them shivered slightly as years of information was wiped from their memories.

Harry grinned. It had taken him a few hours to turn Hermione and Ginny, two of the brightest, most independent women he knew, into his personal sex-slaves, loyal to him in every way. And the day was just beginning.
