[WIP][C] Milking Undies (Pixiv Fanbox)

Hey everyone! The holidays have been very busy for me (in a good way!) so I haven't had much time for drawing, but here's a sketch for the next comm set.

The characters are nobody in particular, but it's been fun drawing some more muscled boys! I am also excited to draw the slime shading, I am a big fan of milking slime undies~
