Gishi waYan Mama Juliya Chuu is a 2020 hentai novelty from the super popular t-Rex Studio and their constant Director Raika Ken. The first of the two fifteen-minute OVA is scheduled for release on June 5, 2020. The story of hentai is set in modern Japan.
Hentai tells about a married woman, as is usual in such stories sexually unsatisfied in married life, and decided to make up for lost time with her brother, who came to stay with her husband and children. What started as a harmless joke on a drunken bench, will grow into a constant frenzied sex always and everywhere, at any convenient opportunity.
