Before marrying her Taiwanese husband, Miu was a nursery teacher, and now works as a big sister at an after-school program. However, she has not been blessed with children, and recently she has not been able to attend night shifts. While she was worrying about this, she became friends with Murata, an aspiring teacher who came to work part-time at the after-school program...and before she knew it, they were in a relationship where she would invite him to her house when her husband was away to meet up...She is a bewitching woman who captivates younger college students with her married woman's sex appeal and maternal instinct, as well as her I-cup busty slender body. Today, after her husband goes to work, she goes wild with an affair and creampie sex at home!!
