The forbidden physical relationship between a brother and sister connected by blood. On a cold winter day, it has been one year since I first had sex with my younger sister Suzuka. Today, the two of us are on a hot spring trip. Suzuka is in her growth spurt, her breasts have swollen, and her sensitivity has improved. In the open-air bath under light rain, only the sound of genitals rubbing and heavy breathing echoes. Suzuka says: I'll take all of big brother's sperm for you?
