Nozomi will be away while her best friend is traveling without water. I had a son, Atsushi, at home, but I'm still a kid. Nozomi wasn't conscious of a man. However, that night, Atsushi suddenly changed by witnessing Nozomi's masturbation. Atsushi impulsively attacks Nozomi's hailless appearance and begs Nozomi for her long-standing feelings. As a matter of course, he refuses, but the young man's pure heart and strong erection power make Nozomi weaken his resistance.
