A perverted father who had been sexually training his real daughter Lara (142cm, hairless) with twisted love now sets his sights on his niece Yuka (136cm, hairless) during the summer holidays. 'Lara, show Yuka how it's done.' The once kind uncle and Lara, who were as close as sisters, make Yuka fear their abnormal incest... Her resisting, undeveloped body is eventually trained to willingly perform deepthroating, swallowing semen, begging for internal ejaculation, and cleaning fellatio. And then... It becomes natural for the two cousins to serve 'Uncle' together.
