Series: Touhou - Acting on Instinct 2 (Doujin) (hiroyuki)

Artist: hiroyuki

Once again, Reimu is in the mood for molestation. Just as she did before, Reimu enlists the aid of the perverted onanist Rinnosuke in subduing victims upon whom she desires to sate her fiendish lusts.
Their targets this time are Kochiya Sanae and Moriya Suwako! Can anything save them from certain doom?

...probably not. It's a comic by Hiroyuki, after all.
