When Joyce called me, and asked me to do some work at her office, I readily agreed. As I drove to her office I wondered what she might be wearing as she seemed to enjoy teasing me with her body. Today was no different, and over the past couple of months I noticed her dress for work was becoming sexier. Her red skirt suit was tailored to her body, and her already long legs looked even longer with high heels, and were encased in black hose. As she showed me the work to be done I was enjoying the tight fit of her skirt on her ass, and I saw no panty lines--a thong I figured. I began to work, and at one point while on my knees I caught a glimpse up her skirt as she sat at her desk talking to a client on the phone, and I swore she wasn't wearing panties at all. By the end of the day I saw she was indeed pantiless, and all I wanted was to go home and stoke to that image as I usually would. She came to check on my progress, and as I showed her what I had gotten done I also saw she was wearing a black nylon body stocking, and no bra. My head was spinning, and my cock was rock hard as I loved a woman wearing a body stocking.
"Jimmy, you ok?" she asked again bringing me out of my thoughts.
"Yeah, just got a lot on my mind," I told her as her sparkling brown eyes melted my heart as only they can.
"Like what?" she now asked moving closer so her perky breast rubbed against my arm.
"Nothing you would want to hear," I told her now looking at my feet like a little school boy talking to a girl for the first time.
"Try me, nothing would shock me," she said with a smile that made my cock throb.
"You," I blurted out before I realized it, "I mean..."
"I know what you mean," she finished for me as she ran a hand down my chest stopping at my belt.
"I'm sorry, you're just so beautiful, and very sexy," I told her as I stood perfectly still.
"And you are only human," she said with a chuckle, "I've been teasing you for years, and you never made a move on me. "
"Cause your my sister," I told her.
"But you still fantasize about me right?" she asked as her hand moved downward feeling my hardness.
"Yes," I said nervously as she began to caress my cock.
"You want to fuck me don't you Jimmy?" she now asked, whispering in my ear as her hand applied more pressure.
