Man, as much Touhou Project as shows up on here, you'd think I'd have learned everybody by now. I suspect that TP fanartists could just insert their own made-up characters into their art and nobody would be the wiser.
Watch out, don't keep your hands in that position for too long. That's gonna make the arms uncomfortable. To stay healthy, I recommend holding boobs on the bed.
For female characters, there are so many you don't need to bother making a new one. It's the hets that are stuck having to force their self-insert into Gensokyo.
