Grandpa's Lesson

Grandpa's Lesson is a slow-burn NTR visual novel that explores themes of manipulation, corruption, and forbidden desire. You invite your aging grandfather Richard to stay with you and your fiancée Suzy for a few weeks, expecting a simple act of kindness. However, Richard is far more cunning than he appears—beneath his frail exterior lies a dominant man with decades of experience who deliberately sets out to infiltrate and corrupt your relationship. Through seemingly innocent accidents and escalating manipulation, he exploits Suzy's growing frustration and your absence, slowly drawing her into situations she never imagined tolerating. The game focuses on the psychological and physical erosion of boundaries as trust fractures and desires become increasingly difficult to resist.
