[DASS-387] Slender busty sister's runaway stakeout cowgirl who truly received her brother's lie Mary Tachibana

- Her younger brother Takashi, who greeted Mary when she returned to her parents' house from Tokyo for the first time in a long time, is excited that her sister, whom she has not seen in a long time, has an erotic body. - Her sister, who is a little natural and naïve and does not doubt people, seems to have been unable to have a boyfriend in Tokyo for a long time, and takes advantage of such a personality and lies that "if you don't have sex for a while, you will say that you are a second virgin and return to virginity".
