When summer vacation arrives, Karen, my student, comes to my old house at the quiet countryside school where I teach, asking for help with her studies. Her translucent black hair sways as she beams with an innocent, pure smile—a girl untouched by the world's corruption. Yet, I don't see her merely as a student; I truly adore her from the bottom of my heart. During this special summer break, our bond gradually deepens. Unable to suppress my desire, I rub myself against her soft black hair, lick her lips, and greedily grope her breasts. Listening to her sweet breath, I release my semen inside her, spending this summer vacation—our secret time—alone together.
