[Onoko Ya Honpo (Kamiwo Akira)] What my Brother Doesn't Know [Eng]

Yuzuki, a deceptively pure-looking, full-breasted man hiding a taboo hunger for his father, becomes caught in a bathroom affair where teasing commands and supposedly innocent rewards steadily erase his brother’s protective ignorance. Urine, bath foam, and slippery soles feed an escalating chain of oral attention, nipple and clit play, masturbation, and forceful penetration, all framed by wet close-ups of straining bodies and overwhelmed expressions. What begins as practical bath assistance becomes a soaked father-son secret, with Yuzuki’s flushed compliance and his brother’s ignorance sharpening the promise of exposure.
