Yumika has a kind husband and a stepson. She wants children soon, but her days are filled with sexlessness. One day, while feeling frustrated, she catches sight of her stepson's huge dick and becomes aroused… After her husband falls asleep at night, she begs for practice in making a baby, leading to a sweaty, bareback sex session with him cumming inside. 'Since you and dad share the same DNA, even if I get pregnant, it won't be found out.' Even though she knows it's wrong… she can't hold back her lust! Bodily fluids and semen mix as they do it multiple times with him finishing inside. She can't tell her husband about the forbidden sex to make a baby with her stepson.
