The Neighbor's Wife ~Forbidden Training in the Afternoon~

A training simulation game set in a residential neighborhood. You accidentally discover that your neighbor Reiko, a beautiful married woman whose husband is away on a business transfer, ordered adult toys to her address but they were delivered to you instead. Realizing her secret, you have 30 days—the duration of her husband's absence—to build a relationship with her by raising stats like "pure love" and "training level" through various encounters. The game culminates in an event on the final night with an uncertain outcome. Your choices shape whether she becomes your romantic partner or something more taboo, with multiple endings and numerous CG scenes featuring Reiko in different costumes.
