You have been wanting to bone Cecilia who works in your office for months.  You recently got a hold of a "naughty pic" that she made for her boyfriend.  It's of her without her skirt on.  You jerk off to this pic all night long, every night.  You are planning to jizz all over it, photography the mess you made, and e-mail it to her.  I am sure she will appreciate that!
