Janna is one of those girls that despite of all my experience with beautiful models, makes me breathless already when she enters my flat and looks at me from her big girlish eyes. When then she undresses and I help her to close the red lingerie sometimes I have to do mathematics in my head to come back from my awakening desires to the reason she is here: taking photos.
(Mathematics: this is an old trick I learned many years ago, when I was a much younger man and had much less control over my thoughts an wishes. So when I felt that my concentration went away from the work, I just did a calculation in my mind, like 356,7 divided by 45,93, and really resolved it. When resolved all other distractions an fantasies have been gone.)
(Fantasies: in the case of Janna, mathematics don't help a lot. She wants to fulfill fantasies, and she knows how to reach her goals, despite of all her innocent looks...)
