The first is Maki, a neat and tidy married woman with black hair and a G cup who looks good in a bob. Even when she works part-time at a karaoke bar, she is hit on by younger customers but she stubbornly refuses them. However, in reality, she is sexless and wants to have sex so much that she picks up the nephew of an acquaintance and goes to his room to devour his young body and genitals! The second is Natsumi, a carnivorous mature woman with a J cup who is still in the mood for sex. She searches for cute younger men and hits them up to satisfy her sexual desires. One day, she finds her cute nephew and while talking about what has been building up for her, she gradually places her hand on his crotch and starts sucking his erect cock.
