Not being a hairdresser I have no idea what I am doing – but just to feel her soft hair and touch her is more than enough. I must have her! I bend o...er and peck her neck.“Glad you like it” – I was expecting a slap after that kiss but she just tilted her head more beckon a further kiss. I duly obliged but longer this time, pursing my lips into her neck and slightly sucking to draw the skin in. Hmmm she smelt so nice I could do this all night.Still brush and caressing her hair I remained kissing. So no one would ever come to know.We locked the door and stood staring at my sister. She was so fucking hot. We then quickly undressed ourselves and my friend gagged her with a piece of chloroform. When we were sure that she was faint, we removed all of her dress except her bra and panty. We then slept next to her such that she was in between us. I could smell her sweet body and I began licking her back while my friend was fingering her. He was a vigorous finger and had pleased my ex-gf. My cock was just inches from her face now and was only very slightly aroused. Carla took my cock in her hand and stroked it a couple of times so that it was at least partially able to stand on its own then she just took in into her mouth. Her mouth felt great on my cock. I had to look to see if the reality of this was as great as I had pictured it in my head on the first day of class. It wasn't. While Carla's technique was excellent and it felt wonderful the look on her face was as if she was. I was taken aback for a moment there, thinking what had just happened. She looked at me puzzled and asked me if I didn’t like it.To this, I replied that I did, but she was my best friend. She came closer to me and told me nobody had to know. That was the day everything changed in our friendship.We would often meet up and have a couple of make-out sessions in the park or at college. This went on for a few months. Finally came the evening before the next day that everything was supposed to.
