A hot summer afternoon spent at my best friend's house. While he was away, I couldn't resist the temptation of my older sister, the dark-skinned gal, Rukawa Rio. In the small closet, pressed against her sweaty skin, I lost my mind to the scent of soap and a woman. With her skilled hands, she led me, who knew nothing, to our first union, taking my virginity. In the darkness of the closet, only her seductive moans and the sounds of flesh hitting each other echo. A summer memory that will never fade, an immoral and stimulating experience that I can never tell my best friend about.
