SeixSu Bondage-ish

I don’t think this would count as a hentai picture, as they’re both still wearing pants. Originally drawn as a kiriban at DeviantART, but I never got it posted. Still working on coloring it. When I’m doing with the coloring, I’ll put the finished picture up. BTW: I know Subaru looks a bit young, so let’s just say that he’s 18 in the picture.
