You sent me a note containing the contents of what you wanted me to draw, and I also sent you a note back with my response to it.
I had to respectfully decline the commission, I am sorry if it's inconvenient to you, but I have seen one of those types of poses overly fetishised and I don't feel comfortable drawing anything like that

I hope you find someone else who would be more than willing to comply to your request, and get the desired outcome you were hoping for
I really do hope you have a nice day
