Yosuke's older sister, Tamaki, who has been provoking in erotic outfits for a long time. When I go to Yosuke's house for the first time in a while, I happen to witness the brother and sister doing post-processing of SEX in Yosuke's room. Kazuya is surprised. Tamaki, who has been known about her relationship with her younger brother, starts masturbating in her room knowing that Kazuya is watching her. Kazuya was soaked in the bath while being disgusted by the appearance of such an older sister. Tamaki, one of the parties, finally appears there. Kazuya on the verge of exploding! ?
