My younger sister Aya suddenly came to my house where I live alone. Aya doesn't want to go back to her parents' house, so she tries to seduce me, her older brother, in order to stay here! I have no experience with women, so I got an erection just by having Aya's grown body pressed against mine. "Shall I take your virginity, big brother?" My beautiful little sister sucks out her brother's semen!
