Mikako, a devilishly cute 25-year-old employee with an irresistible Kansai accent, unexpectedly shares a hotel room with her drab married boss. Crazy for his middle-aged cock and driven by an insatiable sex drive, she keeps asking for more. Her plump ass strains against sweaty pantyhose, her shirt is soaked, and her body gives off a filthy scent. The married boss cannot resist his clingy junior's teasing whispers. Getting caught would ruin his life, but the danger only makes their office affair more exciting, so they forget everything and fuck all night.
