A female college student who ends up having a physical relationship with a woman who used to be like a gentle and lovely older sister. I visit my sister's room and suddenly get blamed at the entrance. A female college student who was swept away by a mysterious pleasure and was taken off her clothes on the sofa while being puzzled was played with an embarrassing look like a manguri. Her older sister sprayed her own tide on the face of a female college student who was stunned by her relentless cunnilingus. While the female college student is guided to the bed, the older sister gently rubs lotion all over her body and caresses her. A female college student who felt love gradually releases her body.
