Recently moved in next door, Yoshino has developed a crush on Nozomi, an active flight attendant. One day, an adult product he ordered is mistakenly delivered to Nozomi's house, leaving Yoshino devastated that his secret desires have been exposed to the woman he admires. Meanwhile, Nozomi, feeling sexually frustrated due to her husband's prolonged absence, begins relieving her tension by toying with Yoshino's cock. Through various aggressive techniques, she repeatedly brings him to the brink of ejaculation, drawing him deeper into intense, escalating sessions. Wearing a chastity belt and denied release, Yoshino continues under her strict control for an entire week.
