.." William stopped short as he realised that thevoice coming out of his mouth was no longer his, but now belonged to hishalf-sister. "Oh my God! I ca...'t believe it." The new Cynthia turned fromside to side admiring her curves in the mirror. She now looked and soundedjust like his sister did. There was a chance that this crazy plan justmight work. He could put all this on, fool his father on the day and thengrab all the money. Cynthia grinned an evil looking grin as she had neverdone in real. But she was nice and friendly and I was the new girl in school so we kind of started talking. Next thing I knew she was having a little get-together at her house for friends. She had a boyfriend and there were a couple of other couples and this guy from my science class who was kind of cute and acting interested in me.I remember when I told Alan that I wanted to go to the thing. He tried to hide his feelings but it was like a cloud passed over his face.I went. I found out a lot of things.. Then I had my breakfast and started to assemble the comp, the same time a lady entered my house and she was bit surprised because she has not see me before. Then she called my mother and they started there conversation, but in-between she use to look at me and asked my mom who is this, and then my mom introduced me to her. She spoke to me in a good manner but her eyes were seeing my bare body I noticed that. Then I moved inside and wore an t-shirt and came out. Then my mom went to the kitchen. We then fell on her bed with our lips locked. I would slide off her panties and begin to finger her burning pussy while she jacked me off. When I could no longer hold it in any longer she wrapped her silky panties around my hard cock and I would shoot my wad in them. "Tara, I got your candy," we heard Mary call up the stairs from the porch. That was the signal that her parents had just rounded the corner and were about ten houses away. I was dressed and was out the back door in under a minute.
