Poor slave, you recently had heart surgery and your heart is VERY delicate while you recover. As you heal you are very much at risk of having a heart attack and you have been advised to take it easy. That's when I come in to visit you, I'm so sweet! I don't actually want you to get better though. It's so tempting to see you so vulnerable. I know if I give you the time of your life and ride your dick into the sunset like you've been yearning for your entire life that it will blow your mind and your heart will explode during orgasm. I know you're too weak to stop me, even if that costs you your life. I know that even if I'm caught red handed, this isn't technically a crime. I'll get off scot-free and fulfill my sick thrill of ending a man.
