Now initiate operation total domination

With Figg as your ally, you start planning for the optimum path for corruption. As said previously, you add your cum to the milk supply meant for Marge and also gave extra to Mrs Figg for her other customers as well. You take the flask and walk back to the Dursleys. Marge is watching television which is typical of anyone from Vernon's side.

"Here's your medicine, Aunt Marge."

"Ah good job, mutt. As a reward, go back to your room and continue your filthy ways or if you want something else, " She grabbed your butt," You have to do more".

You pretend to smile and walk back to your room. On the way, you see Aunt Petunia in the shower you hoped that she would be yours but as planned you need to corrupt her before Marge does. So you grab your invisibility cloak and replaced her shampoo with your cum. To what Mrs Figg has suggested, it should make her now more susceptible to you than Marge. You return back to your room till night. During your rest time, you hear scuttling noises in Dudley's bedroom meaning Marge has tested the potion.

When it was time for dinner, Petunia called you down for dinner. Since Marge was in the room next door, she made out with you quickly before calling Marge. You proceed to go down for dinner.

Dinner was usually quite but with Marge, she always blabbers around after taking a few shots of whiskey.

Petunia would occasionally rub your cock with her feet but as it continued, you unzipped your pants so that you allowed her to give you a footjob. Now, Marge takes her bag and pulls out her flask.

"Petunia, you must try this brilliant milk product from my dear friend. It has an amazing taste with coffee and pretty much with Whiskey as well. "

You had predicted this and as expected, Aunt Petunia took the flask and starts pouring it for all three of you. You quickly gulp down your water pretending that you will take the milk later. Marge, however, was caught in the snag. She had to drink from the milk but she waited until Petunia finished hers, thinking that if she drank after Petunia it wouldn't affect her at all. After both of them drank, your footjob with Petunia was almost complete. You stood up and shot your cum at Marge's face.

This blinded Marge but she didn't make an effort to remove it instead, she started pleasuring herself with her eyes closed. Petunia watched it entirely couldn't hold back anymore. She cleared the table in one swipe and laid on the table for you to take her in. You waste no time as you were hard again, after doing so. You pound on Petunia hard in front of Marge, who was still pleasuring herself.

All three of you climaxed together. Marge had her orgasm hard, Petunia's juice came out of her and covered your cock, you, on the other hand, shot inside Petunia. All was not lost in the end.
