41-year-old Mako Saeki, a married woman who has been feeling stagnant in her monthly sexual routine with her husband, eagerly anticipates her first AV experience, her excitement and nervousness building. She confesses, "During my first sex scene with a male porn actor, I climaxed inside my vagina for the first time—again and again." Mako's pussy is so sensitive that it becomes instantly soaked with just light touching, and the pent-up sexual frustration she's felt since turning 40 is now being fully unleashed through AV filming. Her palpable mix of nervousness and anticipation ahead of her debut shoot is clearly evident.
