My wife is the youngest of two sisters and no brothers. Her oldest sister, Sheila, is eight years older and always trying to prove she's still young. She's 38 and about 5'2" tall and is about 125 lbs. with very nice c cup tits. She also has a very sexy voice and can be some what of a tease.
I knew that she and her husband had a very active sex life. They had no problem talking about it. But I never knew how active.
I was at work at the office one morning when the telephone rang, it was my brother in law, Sheila's husband. He wanted to know if I could talk him through a problem he was having with his computer. I guess I'm the computer expert of the family.
My boss was out of town on vacation and the office was very dead. So, I told him that I could come over and look at it. I left my assistant manager in charge and drove over. They don't live very for so it didn't take very long to get there.
It was about 9:00 a.m. when I got there and Gary, my brother in law, met me at the door. He showed me to his computer and the problem he was having. "No problem" I said as I went to work on his computer. As we were fixing the problem I asked him where Sheila was. He said she was still a sleep in bed. The problem took longer than I thought it would.
It was now 9:45 and I was almost completed. I told him I needed to call a friend of mine and get a code number for a new program I had put on his computer. He handed me the phone and as I was dialing the number Sheila walked out of the bedroom and into where we were. She was wearing one of Gary's button on shirts with only two of the buttons buttoned and no paints. You could she her nice c cup boobs through the shirt and her thong panties.
I was getting a hard on right away.
I she walked over to us my friend picked up the phone. To keep my mind on the reason why I called and to keep Gary from seeing my dick, I wheeled around in the chair and was faced the computer. My dick was still throbbing as I was doing my best to carry on a conversation with my friend.
Sheila then walked up behind me and placed her arms on each shoulder with her hands drooping down and her head just over mine and boobs brushing up against the back o my head. I never wanted hands on the back of my head so bad.
As my friend gave me the code I was looking for I had to lean forward to get a pen to write it down. I hated to move, but I had to.
