Okimiya is the quiet, plain accountant at his company. Isolated from the rest of the department, she seems like a convenient fling for relieving his stress at work. But beneath her clothes she has huge tits and a big ass, and perhaps because she has not had sex in so long, her body is incredibly sensitive. She squirts and cums again and again, making him feel like the world's greatest lover. Deciding she is far too good to remain just a discreet married hookup, he sets out to mold her into the perfect mistress for him.
