"Are you selfish that kindness alone is not enough?" says Mina Matsuoka, 40. She is a mother of one child who usually works as a company clerk. Even now, after 15 years of marriage, the couple has a good relationship and is raising children well. It is no exaggeration to say that it is a fulfilling life, but I am dissatisfied with the night life. - Loving sex with a family-minded and gentle husband is not very satisfactory for Mina, who is looking for a fluke that abandons reason and bare her desires and collides with each other. Frustration is in an extreme state with unsatisfactory feelings hidden in the heart. - "Please blame me until my head goes blank" Please see how the wife, who has only experienced gentle sex for 15 years, drowns her body and mind in beastly rich sex.
