I have a fairly specific request, and I know that (as well as the obscure character) doesn't make it all that likely for someone to fulfill it, but I'll huff the hopium and try anyway. Perhaps the fairly generic character design helps my cause here. Anyway, if someone were to actually do this, it'd make my entire month (if not more), so thanks in advance for even reading and considering my request.
The scenario I have in mind:
The unnamed protagonist of the game Morimiya Middle School Shooting riding a generic white male viewer stand-in's cock (ideally being creampied), either in a classroom or a school hallway, with the dead bodies of fellow schoolgirls shot by her nearby. Cum leaking from the dead schoolgirls' pussies implies that the viewer is some sort of accomplice in the shooter's bloody deeds.
