A secret lovey-dovey lesson with a sheltered young lady ♪

Through a series of coincidences, the protagonist ends up becoming the private tutor of a sheltered young lady.

A proper(?) Live2D touch game

This is a real-time touch game controlled with the mouse.

Stroke her head, undress her, fondle her breasts, have H…

As you raise her affection through touching, her reactions change.

Sannomiya Natsuhi (CV: Akari Mei)

A sheltered young lady. Shy but kind-hearted.

She is curious about sexual matters, yet knows almost nothing about them.

She is a little self-conscious about her slightly plump figure.

A simulation game where you raise the heroine’s affection through conversation and H scenes.

There is no game-over from choosing the wrong option and making her dislike you, so you can play at a leisurely pace.

※ Some choices affect the endings, but confirmation prompts and recovery options are provided.

Plenty of everyday scenes.

Enjoy relaxed conversations with the heroine.

The animations prioritize immersion and are carefully crafted to match each individual voice line.

The production aims to keep facial expressions as consistent with the voice as possible.

Depending on the H scene, you can change her into a swimsuit, bunny outfit, erotic cat costume, bondage gear, and more.
