[JUFE-181] Even though she is right next to her, my humanities sister who closes up big and seduces her whispers dirty Hina Hotaka

As a college student, I was invited to her house for the first time and introduced to my sister Hina- chan. Hina-chan who seems to be sober and serious is shy and has few words. And, hina-chan who had been connected with her in the hallway suddenly adhered the body to me, and slipped the hand into the crotch whispering in my ear , saying that "I am more erotic than the elder sister ...". And she smiled like she was groping me, and she started to show her indecent nature by calling obscene words that she could not imagine from the looks.
