Sorry to be blunt but Requests have a 0.0001% chance of success, most drawn porn that exists is there because someone is paying for it, commissioning it or subscribing to watch it.
I recommend you go to:
www.hentai-foundry.com/ search the porn you want, find the nearest images to it, see if the artist is accepting commissions in their profile, ask how much they are, if they are too expensive, keep searching and asking around until you find an artist cheap enough (some are as low as 10 bucks!, then you can have whatever you like! :)
