[Mosaic Removal] On a day of torrential rain, the older sister next door was soaked wet and lost her house key. The sheer bra that was clinging to her wet clothes was completely visible, which made my heart flutter, and I invited her into the room until the locksmith arrived. From there, the older sister suddenly changed and started seducing me with her wet, transparent breasts, attacking me with excitement. The wet relationship that started from there escalated, and they began to desire each other with their whole bodies covered with lotion and oil.
