I believe that the sexiest of voices comes from a combination of estrus or excitement and genuine pleasure with a bit of exhaustion, so let's imagine for a bit:
When a movement is performed, the body burns a lot of energy, the amount of air inhaled and exhaled increases, eventually the movement of the body becomes sloppy and uncontrolled because a lot of energy has been burnt while the body tries to expel the byproducts in the form of heat and sweat
Accordingly when the sensation of pleasure is introduced to an already hot and excited brain, the brain gets overwhelmed and confused with the amount of input it receives and the output it has to send back, therefore it slows down or partially shuts down, particularly in the cognitive functions, leaving instincts to take over
Which brings us to the larynx - the voice box, where the vocal chords are located. Also exhausted and overwhelmed by signals, the vocal chords produce the most sexy, lewd, and obscene sounds - the oho sounds - simply because it can no longer control itself
