My wife and I are always going to Dr. With our kids for immunizations, check ups and various things. The receptionist is in her mid 40's and always wears skirts nylons and heels. She is actually a very sexy woman. She is a single lady and flirts when my wife is not around. One day she mentioned she needed help moving some large items at her apartment and my wife volunteered me to help. So that Saturday my wife called her then sent me to her apartment. My wife said she was staying home which irritated me since she volunteered to help. I got there and she must have just got off work since she was still wearing her skirt n heels. I moved a couple dressers and table and was done in 10 minutes. She grabbed me some ice tea and we chatted and flirted for a bit. I stood up and said I better get going and she walked me to the door. I turned around at the door and grabbed her and started kissing her. My heart was pounding so fast, I couldn't believe I did that and she was letting me do this! She was moaning loud and went straight for my erection. We slowly worked back to the living room as she kept moaning and pushing my h****** down then telling me how stiff and strong my c*** was. I unzipped her skirt and unbuttoned and removed her shirt and took off her bra. I took off all my clothes for her and walked her to her bed room. She sat on bed and put my h****** in her mouth. I then laid her back and started kissing her p**** lips. I pulled her pantyhose and panties off and started licking and sucking until my face was soaking wet. I stood up and her pantyhose were hanging off my hard c*** bouncing up and down. She giggled and jacked me off with her pantyhose which felt real good. I rolled her over and stood by the bed while she was on her hands and knees on the bed and drilled her doggystyle. She was literally screaming in her pillow before I shot my load in her! I hurried and got dressed and she said we will have to do this again sometime. I hope soon! My wife is never that sexual and she has no suspicion either.
