How to get the cum into a squirting cock?

I have been wanting this squirting dildo for months now, and so finally the other day I bought it, and it woke me up this morning (well, technically the mailman did). I have a feeling that I'll have some fun times with this cock.

Here's my problem though;
The cum-situation (how to make it) has long since been figured out, but how in the world do you get it INSIDE the cock to begin with? At first I thought that you were supposed to remove the suction-cup and put it in there, but by the look of it (and after glancing through the tiny manual), it seems like you're not supposed to remove it, so now I'm completely clueless...

Anyone of you girls know how?

(If it makes any difference; it's a Doc Johnson - I guess in worst case, I'll have to ask them directly, but I'm sure I've seen some of you girls mention owning the same thing earlier, unless I'm imagining things. After all, I did just wake up.)
