[Commission][WIP] Brothers Kidnapped 4 (Pixiv Fanbox)

The lines for the next Pixiv Request ^^ You might remember this boy as the little brother from my old Brothers Kidnapped series! Seems he's in quite a bind at the moment, tightly roped to a chair in a dark basement and nothing but hours of struggling and mmphing to keep him occupied~ I guess the stranger who bought the three boys is quite a fan of classic GID situations!
