The music she had playing provided the perfect cover for me to make it up the stairs, across the living room, and down the hall to her room without ever being heard. Apparently, she was so comfortable in thinking that no one was home, that she didn't even bother to close her door all the way. "What a bonus!" i thought, grinning to myself. I made it all the way to the doorway, and slowly peeked my head in around the frame. what I saw almost made me give myself away! Linda was leaning over her desk reading the magazine. One hand propped herself up while she used the other to finger herself. This was incredible! I really shouldn't have been watching this, but I couldn't help it. I was stunned. She was wearing only a set of silver stockings and a pair of black platform heels that made her slender legs even longer and more delicious looking. Linda had a body that most porn stars would envy. She was moaning a little, and gyrating herself onto her own fingers. I wish I could have seen which pictures she was looking at, but guess it didn't really matter at this point.
What should I do? I couldn't remain unnoticed for very long. Sooner or later, I'd have to duck out or risk being caught, but I think I was trying to convince myself otherwise. So, there i was, spying on my sister as she finger-fucked herself while reading one of my porn mags. Who knew my day would end up like this?
Linda stood up a bit and opened one of her desk drawers. That was when I figured my luck would run out, since her desk had a huge mirror in front of it, and all she had to do was look up, and this little voyeuristic venture of mine would end in what would no doubt be the loudest verbal explosion I'd ever heard come out of her mouth. Holding my breath and trying not to move a muscle, I watched as she removed a huge rubber cock from the drawer and put it in her mouth while she resumed her previous position. She moved it in and out of her mouth, making sure that it was well lubricated, and the she slid the flesh-colored monster down between her legs and guided it straight up into her pussy. I was shocked! My mind was spinning, trying absorb the image before me, and still be silent.
It took a few moments before she was able to fully accommodate her instrument of pleasure, but what a gorgeous site it was. I think I was actually jealous of that thing!
A couple of times her legs began to tremble and then there was a quick jolt, followed by a deep sigh and an almost musical moan. She was really enjoying this! I stood there and admired her actions until I finally figured out which scenario she was acting out. She was talking out loud to an invisible person, and I could tell by what she was saying that she was fantasising about being a young secretary working her way up the corporate ladder. It as after quitting time, and she had gone into the boss' office and offered her services to him, which he gladly accepted and took advantage of. He said he was under a lot of deadline stress, and he needed someone to help him out, and relieve some of the pressure off. Without saying a word, she obliged by leaning over his desk and slowly lifting up her skirt to reveal her intentions. There was no need for a verbal response from her boss, who proceeded to move in behind her.
This is where I walked in...
"Oh, David, I want you to relieve your stress inside me!" she said aloud. Again I was shocked! I knew the name of the man in the story was Richard (the Big Dick in the office), and the name of the guy she has been seeing is George, so... Was she actually referring to me?? I decided to assume the affirmative, and go for broke. I slowly made my way towards her.
