Serafall Leviathan vs Rias Gremory by Sanone

Here's a commission pic made by of Rias taking on Serafall in a battle of skimpy outfits and bubble blowing to see who gets Issei to be their mate. The bubblegum actually expands parts of their body that's worth a second look every dang time. Give credit to him for making this one for me. >w<
