Overview

Grandpas’s Lesson is a slow-burn NTR Visual Novel focused on gradual corruption, guilt, and forbidden desire.
You thought inviting your aging grandfather, Richard, to stay with you and your fiancée Suzy for a few weeks would be a simple act of kindness. After all, he’s just an old man — strict, traditional, and a little forgetful after his accident.
But Richard is far more than he seems.

Behind his frail appearance and clumsy behavior lies a cunning, dominant man who knows exactly what he wants. With a massive endowment and decades of experience, he begins to slowly, deliberately infiltrate your relationship — exploiting Suzy’s growing sexual frustration and your long work hours.
What starts as innocent “accidents” — lingering hugs, clumsy touches, “therapeutic” massages, and helpful hands — slowly escalates into something much darker and more addictive. Suzy tries desperately to resist, telling herself she’s only being kind, that she’s just helping an old man… but the seed of corruption has already been planted.
