For three days and three nights, Mei Itsukaichi was intimately seduced every night in the bathroom by her stepsister, who possessed innocent love and G-cup breasts, and subjected her to continuous, intense ejaculation. (DASS-451)

My parents were traveling when my older sister came back. She played with her nipples, her unguarded look exciting me. She even sneaked into the bathroom, saying, "Let's get along, okay?" and we showered together. My involuntary erection was carefully stroked. It was a milk cannon paradise with her huge breasts. Her breasts clamped my glans and...! Our wet, sticky genitals rubbed together, arousing us. We couldn't resist. We had unprotected sex, going beyond sibling boundaries! We climaxed in the M-position. Our perfect synchronization caused me to ejaculate. Though shy, I still twisted my hips. We climaxed again in close-up sex! Even when my parents returned, we secretly continued thrusting. The bathroom was our secret hideout.
