Someone in the notes that that anon was asking about says that it's from Bible Black... and honestly, imo, the third one doesn't look like it's from a yaoi, either, since the bottom is drawn so differently from the top.

Ahh ok, then that means they aren’t even yaoi hah. But the third one could very well be fanmade. Ah well, thanks! ^^
