My nephew Hiroki decided to visit his relatives, Mr. and Mrs. Akai, during summer vacation. Hiroki, who has longed for his aunt since he was a child, cannot contain his excitement. That night, I couldn't bear it and secretly watched my aunt masturbate... Her aunt, who noticed her eyes, saw that she had little experience with women and forced her to do the same. So. This summer, Hiroki will have an experience he will never forget.
