I very much like that image.
Take a pen or marker, whatever is the closest. Slide your panties to the side and fully insert it into your pussy a single time. Take it out, and take a good look at it. See how wet that pen has become from a single insertion. Don't try it off, leave it on your table. Look at your tack bra hiding under a book. Remember how good that felt. Look at your tits, imagining ripping the clothespins off once more. Look at your panties, slowly but surely coloring dark. Look at the words on your body. marking what is happening to you.
Then finally, look once more at the pen, and use it to write a single line on a piece of paper: "I am needy, blushing, being toyed with, and I absolutely love it." Hide the paper in the book, with just a little bit sticking out.
