GRMO-132 Human observation: The plain, glasses-wearing coworker who seems easy to push around transforms into an ultra-slutty girl when it comes to dick.

A man rolled into his female coworker's place after missing the last train following a drinking party. He enjoyed her innocent reactions to his advances and forcefully initiated sex, but as soon as he presented his dick, the woman who had been so prim and proper transformed into a nymphomaniac. Overwhelmed by her expert fellatio, he nearly climaxed multiple times, writhing in ecstasy. It seemed that instead of him having his way with her, he was shamefully devoured.
