Shove markers in it!

Not about to let her many interruptions of your sleep go, you decide to have some fun. You go over to your desk and pull out all six of your dry-erase markers. Starting with the black one, you push it in easily with almost zero resistance. Considering that the disk only an inch or two thick, you're surprised by the fact that you are able to fit the entire marker inside of the vagina. Considering that this is only possible by what is apparently magic, you decide not to question it.

You then push in the blue one with only a little bit of trouble. God, Allison is such a loose slut to be able to easily fit two of these markers. Trying to push a third one in, you hear more shrieking from next door.

The third one won't seem to fit in, because the end is so blunt that you can't get it into her. Instead, you take off the cap, and shove the marker point-side first into her, and are able to fit it in snugly.
