Superhero Costumes for sex

Hi everyone! I wonder if anybody know some places where you can buy superhero costumes that are usable for buttsex. I have one suit with a zipper in the front for the cock but haven't found anything with a zipper for the butt. Tipps would be highly appreciated!

Do you know a tailor? Actually, I have seen crotch zippers that expose the butt, but no clue where I saw them offered.

I found a site which sell superhero outfit called http://www.unclehulk.com/ , I haven't brought a suit from them so I don't know if it what you are after but under the additional option there 2 choices: Crotch Vertical Zipper (front to bottom) or Long Crotch Vertical Zipper (front to back) There no pics of the crotch zip but by my guessing maybe the long crotch zip might be access to your ass. I will be buying a suit from them maybe next month when I have the money and I will let you know as I would love to be able to get fucked in my superhero outfits.
