Mao Kurata, a busty sister-in-law, decided to go shopping without a bra, thinking "it's just a short trip, it'll be fine." On her way home, she was caught in a sudden downpour and got completely soaked. With no bra on, her T-shirt clung tightly to her breasts, clearly revealing her nipples—leaving her embarrassed and exposed. Her brother-in-law, seeing her in that state, instantly got a hard-on. When she noticed his arousal, she panicked at first, but then found herself shocked—and increasingly turned on. Unable to resist the tension, she ended up passionately desiring him, leading to an intensely erotic encounter far beyond what either expected. *Note: This title is a solo selection from the previously released multi-performer work "HUNTA-880" by Hunter under the HHH Group's Premium Select series.
