This summer, the family's midsummer vacation was canceled, leaving Mio with no chance to wear her new bikini. Feeling down, the beautiful mother decides to cheer herself up by holding a solo swimsuit fashion show in front of the mirror. Just then, her son Kota happens to walk by and offers to give her an oil massage. Wearing a sexy bikini that only covers her nipples and pubic area, Mio's body excites Kota as he touches his mother for the first time. As the massage reaches more intimate areas, Mio gradually becomes aroused, her desire building until she reaches a powerful climax.
