Ms. K is a 25-year-old divorced woman living in Osaka with no children. She has had very little experience with men, and her ex-husband is her second. The main reasons for her divorce were that her sex life with her husband was just enough to insert a penis and that she had a small penis. She appears calm and collected in how she speaks, but when she climaxes, she lets out an insane scream! This book features five married women with unusual sexual fetishes.
