DKD-010 — My Sister Is A Shut-In And A Loner, But She Has Big Tits And Is Cute, And She Only Licks My Dick. Kasumi Tsukino

In the winter of her second year of high school, Kasumi suddenly became a recluse at home. For several years since then, she has been living a self-indulgent life without even stepping out of the house, but when she started streaming online for the sake of tips, viewers mocked her for not being very good at conversation or sex appeal, and she set her sights on her younger brother Yuto, saying, "I'd like to lick a dick just once for the experience." Yuto, who secretly had special feelings for his sister, accepted her request, and Kasumi, who was obsessed with male genitalia, began giving him a blowjob almost every night. One day, Yuto said, "I want to take our relationship to something more than just siblings," but Kasumi refused, saying, "We're siblings." Angry, Yuto started dating a girl from his class to spite his sister, and when Kasumi witnessed the scene, her emotions were greatly shaken. Even though he was her younger brother, and they weren't even lovers, she just wanted to see his dick... She felt intense jealousy for the first time. "I can't forgive you, Yuto's dick is mine!" Is this lust or love? Tsukino Kasumi plays a bro-complex girl who becomes obsessed with her brother's penis!
