While Ayaka’s husband is away on a solo assignment, his adult brother visits her, only for a torrential storm to halt the trains and force them to share a hotel room. The sight of his drenched sister-in-law sends his lust out of control, and they cross the line with creampie sex. Alone together, she gives him a deep blowjob in the bath, then tempts him with wet hair and nipples visible through her clothes. He pounds her curvy ass all night and fills the woman he has secretly admired again and again. Even after the sky clears, they keep fucking until the storm has changed his world forever.
