004IBW-463 Secret incest trip with little sister Yuu, age 1●. ★ Kagami Shuna

Forbidden physical relationship between blood-related brother and sister. One day when I was sleeping in the same room, my forbidden relationship began after I held her sister in heat who unconsciously rubbed against her crotch. Today I'm alone with my brother and sister at a hot spring inn. The energetic and naughty little sister is an estrus kitten who is immersed in sexual acts that she has just learned and begs for sex, saying, "If you get pummeled with cocks, your head will turn white."
