Bart Simpson Gangbang - Fan request (Pixiv Fanbox)

I had this illustration hanging around for years... the fist time I sketched this one was in May 2020, at some point I had the lineart done and part of the colors and shading, but never got to finish it!

Someone asked for this specific idea in SubscribeStar and the illustration only needed a few details and that was it. Easy peasy.
