薄壁の向こうで姉が我慢できずに漏らす喘ぎ声を聞いて発情しだす妹 2

A man who was teaching a younger sister studies makes a move on the older sister. The older sister resists the sudden event, but as she is caressed, she becomes aroused... She struggles to keep her composure and desperately tries not to let out a sound so her younger sister won't notice, but the younger sister, who had been aware, listens from the next room and masturbates. Even after the man returns to the room, her excitement doesn't stop, and in the confusion, she begins to suck his dick, obedient to him despite her fear.
