Forma Cumulatus

After a bit of hesitation you decide to attempt casting the spell called 'Forma Cumulatus'. You start by checking its requirements. Fortunately someone has already translated the list so you don't need to do it yourself. It turns out the spell requires no special preparations or rituals. All you need is:

• to be female - check
• to be alone, preferably in a place that is not visited very often - check
• to make sure no one will disturb you - you already locked the door, so check
• to sit on the floor completely naked until the casting is complete - you quickly take off all your clothes and throw them on your bed before sitting on the floor with the book in your lap
• not to masturbate until you've cast the spell - that seems a bit weird - why would you masturbate while casting a spell unless it is necessary? You wonder why would anyone put this on the list of requirements? But it's not a problem so you shrug it off.

You double-check to make sure there are no other requirements and that you'll be able to read the spell correctly, and then you finally begin. As soon as you've read the first few words you feel a heat in your pussy. As you read more the heat grows. Your love juices start flowing out of your cunt and down to the floor where they make a small puddle. The more you read the greater the heat becomes and it?s not long before it spreads over your entire body. Soon you start feeling the need to cum. Thoughts of rubbing your clit with one hand while finger-fucking your twat with the other start appearing in your mind, and in your current condition they are almost too tempting. But you remember the requirement not to masturbate (now you understand why it was in the list) and concentrate all of your willpower on finishing the spell without giving into temptation.

It takes a tremendous effort but you manage to resist and finish casting the spell before your willpower fails you. As soon as you are done reading the spell the heat becomes unbearable and without even touching yourself you climax like never before, letting out an orgasmic scream so loud that probably everyone in the building heard it. As you come again and again everything goes white?
