It’s a cute doujinshi, that one, about an old series, old even by my own standards: Urusei Yatsura, or Lamu as it was called in my country.
In it, the oni-woman, Lum, forgives Ataru (her boyfriend= his endless inconsistence and flirting with random women, and has make-up sex with him. It’s kinda plain but it is enough to create a vanilla atmosphere, let us say.
If you manage to ignore the male MC’s horrible bomber jacket (lol), the drawings are sensible and skillful, giving hentai life to a fine anime girl.
By Kaitou Pink, I also share A pack of 4 works (High! Imouto Tension + Medaka-chan Bakko Bako + Together With The Popular Idol + True Feelings) and a pack of 3 works (Fitting Wedding Dresses + Iiwake Study c1-2 + Sister Hunter). I also used to share JAV with her, but scratch it, the links kept on dying super fast.
