Aki Sasaki works for a unique agency that provides professional surrogate mothers for busy parents, stepping in to care for children when their biological mothers are away. Her latest assignment brings her into the home of young Kenichi, a curious boy who is eager to play games while his mother is out. During an innocent session of pretend superhero play, a wardrobe malfunction reveals Aki’s slender, pale thighs and delicate lingerie. The sight quickly shifts the dynamic of their afternoon, as Kenichi decides to play the role of a monster, using the opportunity to get hands-on with Aki’s soft, beautiful curves. What starts as a playful afternoon quickly evolves into an intimate exploration that pushes the boundaries of their professional relationship.
As the day transitions into evening, the intimacy between the pair deepens significantly. Kenichi expresses a desire to be nurtured, and Aki willingly indulges his request, allowing him to suckle her breasts before bedtime. The following day, Kenichi returns home in tears, confessing that he is being bullied by his peers for his lack of sexual experience. Moved by his distress and wanting to help him gain confidence, Aki decides to take his education into her own hands. She begins to guide him through the intricacies of physical intimacy, turning their sessions into a private learning environment where he can practice what he reads in adult magazines.
This newfound arrangement transforms their daily routine, as Kenichi frequently applies his latest discoveries to his interactions with Aki. Far from being hesitant, Aki finds herself genuinely enjoying the progression of their relationship, happily encouraging Kenichi to explore his desires and experiment with her body whenever he wishes. This captivating story of forbidden guidance and mutual discovery offers an intriguing look at how a professional bond can evolve into a deeply personal and uninhibited experience between two willing participants.
