My Girlfriend's Naughty Sister

All the protagonist truly desired was a moment of intimacy with his beloved girlfriend, yet that simple wish remains perpetually out of reach due to the strict prohibitions enforced by her older sister. Determined to bridge the physical distance and spend private time together, he quietly resolves to sneak over to their home one unexpected evening, hoping to bypass the rigid boundaries set against them. However, upon his arrival, the situation takes an unforeseen and baffling turn. Instead of being greeted by the comforting presence of his girlfriend, he finds an entirely different surprise waiting for him in the shadows: the older sister herself is the only one home, setting the stage for a tense and complicated encounter that threatens to upend everything he expected from the clandestine visit.
