I got married after my husband approached me vigorously. He is a very kind man, but there was one thing I was dissatisfied with. Although I think our sex life is normal, he is very selfish and I have never had an orgasm. I have never known any other man than my husband, so I thought that this is what sex between a married couple is like, but then I met my neighbor, Takada-san... Since then, I have changed from a chaste and serious woman into a lewd woman.
