[Maka Fushigi] Deli hell time [Higeteca]

A guy caught mid-stroke accidentally unleashes a horned demon genie from his dick, and her very first act of freedom is granting his deepest wish—casting a spell that turns his little sister Kiiro into a lewd, brother-obsessed little sibling eager to worship her onii-chan. What begins as a granted fantasy escalates into raw, tearful sibling sex, with the brother pounding her bare and promising to pour her full of semen while vowing they'll do it every day from now on. But as Kiiro sobs that it hurts and the genie's magic mysteriously stops working, the wish takes a turn nobody bargained for—congratulations on graduating from virginity, indeed.
