For those who have read the title of this blog post and thought we were publishing a SSSS.Gridman parody, our apologies. Though the title of “SSSS.Incestman” would be quite appropriate for this original doujinshi from Akiba Maou, since it’s 100% about a super lewd sister whose brother just can’t catch a break.

Imagine the puns we could have made if the title was “I’m Sure Even God Will Forgive Me If I Have Lovely-Dovely Sex with My Beloved Brother”. What a shame.
