After many days of waiting, my cousin Kawamura finally came up from the countryside to visit. Still being a high school student, she looks quite innocent, with a lovely figure, however, her sexual skills are impeccable. We have had feelings for each other for a long time and have secretly had sexual relations many times despite her still being in school and knowing that this is incestuous. Therefore, this meeting may be our last time having sex to put an end to this wrongful relationship.
