Yuna, a beautiful female doctor, is frustrated by her demanding work. When she notices that a male patient has an erection late at night, she is unable to suppress her lustful feelings and ends up sucking his dick. The male patient is surprised by her sudden act, but she skillfully seduces him, leading them to enjoy erotic acts together. When she sucks his dick with her wet pussy, the man becomes her slave. This is exactly what it's like to have a brainwashing sex session with a perverted older sister who whispers obscene words in his ear while moving her hips nonstop!!! *This work is a re-edited version of "Whispering Dirty Words and Talking Pussy" (product number: wss00275).
