At that moment, Kozue (Kozue Tokita) impulsively pushed her son down and began sucking his cock with all her heart. After her husband developed erectile dysfunction, she was frustrated by the constant days of sexual frustration, and by chance she witnessed her son masturbating. The force of his erect cock instantly took away Kozue's reason. And her son, who is of Kozue's blood, also had an excessive sexual appetite... Not satisfied with just one thrust, he would quickly recover and repeat his violent thrusts before pulling out. Two, three, four. After being thrusted endlessly, Kozue finally went into a state of frenzy.
