I am listening Foxy's [*Get off*](https://www.youtube.com/watch?v=aGajlQvuwHU). The lyrics is as following.
**I am wondering what the idiom "get off" mean at here?**
I know that "get off" is used to meaning "to leave or to descend from a vehicle".
But it seems to be weird if I explain the idiom as leaving from a car at here.

Pretty ladies are at our discretion  

So we can get off  

We keep under the sheets with two lovelies  

So we can get off

Sly look that we keep the promise, ladies  

And make me get off  

Take it from girls with our imagination  

So we can get off

Call me up at your place, I can love you crazy  

In the heat you will understand  

Danger and excitement, that's what makes a lady  

Find out what she wants in a man

To get off, to get off, to get off, to get off  

To get off, to get off, to get off, to get, get off

Lookin' through that dress that drive me crazy and makes me get off  

Sensuality excites my mind, it makes get off  

If I were you I'd get a good perspective on how to get off  

Love me wild and love me crazy, so we can get off

Call me up at your place, I can love you crazy  

In the heat you will understand  

Danger and excitement, that's what makes a lady  

Find out what she wants in a man

To get off, to get off, to get off, to get off  

To get off, to get off, to get off, to get, get off

Get off

So get off to get off, to get off, to get, get off  

Get off to get off, to get off, get off  

So get off, get off, to get off, to get, get off  

Get off to get off, get off, get off

To get off, to get off, to get off, to get, get off  

Get off, get off, get off, to get off  

Get off to get off, get off, get, get off  

Get off, get off, so get off, just get off  

Get off, get off, get off
