My Sister is My Girlfriend!? Sexual Relationship for Two Nights and Three Days

My Sister is My Girlfriend!? Sexual Relationship for Two Nights and Three Days

妹がオレの彼女!?2泊3日のエッチな関係

A young man is ordered by his older sister, Nonoka, to pretend to be her boyfriend during a group trip. They must act like a couple for two nights and three days, but the physical closeness quickly blurs the line between performance and reality. As they share a bed and engage in flirtatious behavior, his self-control begins to crumble under the pressure of her teasing and their forbidden attraction.

Nonoka has always been strong-willed, but her provocative actions push him to his limits. Caught between the need to maintain their act and the growing desire he feels for his own sister, he struggles to resist. The trip becomes a test of willpower, where every accidental touch and intentional tease threatens to lead them down a path from which there is no return.
