Blackmailing my sister for sex.

It was the summer after my high school graduation and I had nothing to do till I started college in the fall. I had not been able to find a summer job so I was just going to hang out and relax for the next couple months. We lived in an upper middle class neighborhood in a nice house on a two acre lot and we had a pool at home so I expected to spend a lot of time in it and to invite friends to come over and join me. I was planning to invite a lot of girls and hopefully convince them that swim suits were not required.

My name is Rex and I had just turned 18. I lived with my mom and dad in a suburb of Dallas. I also have a sister named Sandra. We all called her Sandy. She was 22 and had her own little apartment a mile or so from home. She worked downtown at a company that has something to do with financial investments. She was the company president’s personal assistant.

One day I got the urge to go down and have lunch with Sandy so I arrived at the building that the company was in at a few minutes before noon. Her lunch started at noon. I went up to their offices on the 12th floor. Everyone there knew me so no-body questioned it when I walked in, walked past them and went back to the president’s offices. Sandy had a desk in his outer office but she was not at it.

The door to his office was closed but not completely. I thought about asking him if he knew where Sandy was. Maybe she had started lunch a few minutes early and had already gone out with some of the others from the office. If so, it would not do me any good just to wait around for her to get back to her desk. I started to knock when I saw something thru the small opening in the doorway that made me stop.

Mr. Donniger who was about 50, chubby and going bald was leaning against the front of his desk with his pants on the floor. Sandy was on her knees in front of him, giving him a blowjob. You could see enough of both of their faces to easily tell who they were. She had her top off and he was fondling her breasts. She was doing a great job. Sandy has big tits and I have always wanted to get my hands on them but never figured out a way to do it. I guess that being her boss was a good way. She is attractive and about 5’5″ and not more than 120 pounds with tits that I am sure are D-cups. They did sag a little but I guess that it is hard to hold up all that weight.

I pushed the door just a little way further open and took out my cell phone.
