Wait a moment, I see Mrs Figg signalling me..

You see Mrs Figg across the street, it seems she wants to chat with you. You go to her house where she invited you to come inside. As soon as you sit on the sofa, you hear Mrs Figg coming. But this time she has changed her appearance into a MILF. You instinctively take out your wand and point at her.

"Who are you and what have you done with Mrs Figg..."

"Harry, it is me. Mrs Figg. I know it is shocking but I will explain in due time. Besides, since your curse is still on you and I thought it would be better if I transformed to this muggle to grasp your attention."

She was right. It worked. You stuff your wand back and you sit on the sofa.

"It seems that you have had your fun with the Dursleys but you still couldn't figure out what to do with your new type of cum. I would have helped you in scoring with your aunt faster, but I believe you took it out without my help. The reason why I called you is that I'm obligated to do so. I was bound to serve you until you find the origins of the curse that was cast on you after the Battle of Hogwarts. The reason why I was able to shapeshift is that my breast milk has seductive properties but in turn would allow me to transform into them. Your Aunt Marge was one of my clients, and I do not know what has happened to her since I can't transform into her. Now onto the most important part: Your cum, Harry, is the secret that makes it easy for you to dominate whomever you wish. In this case, your wand can only assist you and your cock is your greatest weapon. You can make your targets susceptible to you alone either by ingestion or indirect contact in form of drinks, lotions, etc. I apologise for not helping you from the start but I was bound not to do so. Do you have any other questions, Harry?"

"By serving me, does that mean--"

"Yes, I will be part of your harem. Another thing you need to note is that unless you shoot inside at least once in your target to make them a part of your Harem. Also, should you shoot in me this time you will be able to use me anytime to transform into any members that you have brought in your Harem, which may include Petunia if you had done so."

You smile widely, now knowing that you have a personal **** but also a shapeshifter in case you go horny. You imagine the possibilities where you fuck Mrs Figg as Hermione, Ginny, Fleur, etc. Mrs Figg comprehended that and pulled you towards her bed to seal the deal to serve as your personal fucktoy and assistant.
