004IBW-496 Secret incestuous trip with little sister Suzuka, age 1●

Forbidden physical relationship between blood-related brother and sister. One cold winter day, one year after having sex with her sister Suzu for the first time, the two of us came to a hot spring trip alone. Suzuka has entered her growth period and her breasts have swelled and her sensitivity has improved. Only the sound of her genitals rubbing against each other and her intense breathing reverberate in the open-air bath where the rain falls quietly. Suzuka will take all her brother's sperm, right?
