Knock knock

I was sitting at the first floor with a great view on the balcony and the garden through the big window from floor to ceiling. Nobody can see me here. I'm wearing the extreme short miniskirt I bought a couple of days ago. Underneath tiny, lacey black panties caress my sex. I see them when I look down. The skirt is indecently short.
I'm having a naughty chat with a truely sexy girlfriend on yahoo. She just woke up and caresses her body while we talk. I want her to see me. I propose to put on the cam. She feels like it but there is no time. She has an appointment. We decide to meet again on skype on a later occasion. She's off only for a minute when I hear someone knocking on the balcony door which is a window too. I'm totally surprised. How is it possible that someone is on my balcony? I'm astonished to see it is the prude and pretty girl who lives down the street. She sees me sitting there. Relief and surprise mingle on her face. I panick. I need to get up to put on my trousers which are on a chair. I'm naked to the waist and below there's this whore's skirt, hiked up, exposing my bulge which is not covered entirely by the shiny, sexy knickers. She puts her hands before her face and laughs. She needs to get in. That's what she wants indeed since she had locked herself out of the garage and had taken refuge here, climbing on the neighbour's flat roof. In a hurry I put on my jeans and a shirt. She is embarrassed, surprised, she giggles and apologizes vaguely, sketching her situation. I'm half dressed. Nothing can be done but to act as normally as possible. She takes off her pretty, sexy boots and tiptoes through my study to the stairway and the front door. How will she think back of this unexpected encounter. Will she talk to anyone about what she saw. Was she shocked? Fortunately my yahoo friend needed to go. If not my unexpected, sexy and innocent guest could have witnessed me dancing, gyrating and wanking in front of the cam...
