Double double cross

"Ha! The drug worked! Not only have I eliminated my rival CEO, but I've created a sex slave who will follow my every order. Now crawl over here and suck my clock."

"Not so fast, asshole. I bribed your chemist to remove the mind control component from the drug you slipped me. Then I set up an identity as your long-lost daughter and had myself named as the heir to both of our fortunes. Finally, I slipped you the same drug you gave me, with the mind control elements restored. So crawl over here, sweetie. I feel like a tongue lashing is the proper way to celebrate my new-found wealth."
