During the treatment, he secretly applies an aphrodisiac to her penis and immediately fucks her from behind! The girl musters her strength to run away, but the aphrodisiac's effects make her stagger and her consciousness fades away. Once she has lost the will to run away, he thrusts his penis into her again from behind! Then she cums over and over again with an ahegao face that has lost all sense...she goes into acute heat! The honor student high school girl suddenly turns into a lewd girl!
