For those who know Spanish, what is this song about? Is it pillow talk?

I heard it on CBC radio a few times, and have taken quite a liking to it.

The song apparently is “Pa Que Vuelva” by a “Telmary”.

I’ve been doing a decent amount of searching on Google for a video of the song but to no avail.

Here’s a video with the artist.

Here are some audio hints.

The only thing is, it’s live.

Here’s a bit of the recorded version:

What are the lyrics about?
(Follow up question: Is there a video I can link to?)

Thanks.
