I debated calling her to apologize. Unfortunately, the store was busy all day, so I never had the chance.My mind was working overtime though. Dexter w...as a big problem. He had always been an issue, but now he was coming between my sister and I. There had to be some way to get him out of the picture. I was daydreaming, ringing up a customer's order, when a plan suddenly came to me. I knew just what to do. If my theory was correct, Dexter was history.Normally I am not a devious person. I tend to. "Have a good day at work babe." You too." Callie reached up to kiss her brother goodbye.Arriving to her office that day, she hurried being about three minutes late.

I started to swim in front of him, exposing my pussy and ass as soon as he had his head under the water. He was following just two meters behind me and It was so thrilling to have him there see absolutly all of me.
