You need a few things to complete this tease properly, so you can get them now, or wait until they are called for.
The first is pair of panties of course. They are not a requirement per se, but its just so much more humiliating for you to wear strokepanties while jacking it for your CRUSH, don't ya think?
The second thing(s) is a good clear photo of your CRUSH, one where she is looking right at the camera, preferably a nice head shot.
I know you two are probably facebook friends (have you jerked to her pics before?....you probably have...don't deny it.), so find a good clear pic there. You should also get a photo where you can clearly see her body, especially the body part you have jerked off for most in the past (don't lie, stroker..).
And third you need a cumcatcher. Either a small plate or a shot glass will do fine. I'm sure a regular cumslurper like you has the perfect thing handy. <grin>.
