Yes, this is an early draft of the Kanako/Suwako I commissioned from Ondine. You'll notice that Suwako has breasts, Kanako has bigger breasts, and that Pyonta is blushing (adding to the lewdness).
While I liked the end result (I told Ondine to reduce the size of Kanako and Suwako's breasts), in retrospect, I feel like the original was still better.
Still, in both cases, I'm really happy how it turned out. I want to reach in there and squeeze Kanako's thighs or breasts, or Suwako's stomach or butt, and I have literally never felt that way about a fan work before.
