[Fuwatoro Opanchu Cake] A late night visit leads to a mother and son's marital sex life together

A late-night visit draws a married mother and her son into a charged, taboo encounter, beginning with sleepy confusion and awkward hesitation before their attraction takes over. The story moves through intimate experimentation and overwhelming physical pleasure into a softer aftermath of cuddling, reassurance, and talk of staying together. The shifting tension between surprise, desire, and emotional commitment gives the album a charged yet surprisingly tender atmosphere.
