Shizuka presents a free erocosplay photosetSaeko Busujima in Black Keyhole Lingerie, Garter Belt and Stockings

Is it Saeko from HOTD or Revy from Black Lagoon? Maybe both? I'm not sure anymore and I don't care as these photos of Shizuka in cupless bra and backless panties make up for whatever amalgamation my brain produced.

This photoset might have started out with a simple tank-top and shorts, with just some garter straps showing through...
...but by the end of it the sheer amount of keyholes from nippleless bra and backless panties is going to be through the roof, I promise you.
