My Carpool Friend

At the hospital I work at I work in a medical supply room. The room doesn't have any windows and only one door. Very few people have keys to this room because some of the supplies have to be stored in a very secure area. The door is always locked and you can not enter without a key. Last week I heard a knock at the door and it was Katy. I let her in; made sure the door was shut and went back to work checking supplies. Katy was in our area delivering urine samples to the lab and stopped by to tell me she would be fifteen minutes late that night and for me to hold up the carpool. I told her I would. We were doing the usual chit-chat when her eyes came across the box of medical lubricant I was unpacking. Katy asked me if I knew how well the lubricant worked. I laughed and told her that you could push golf balls through a garden hose with this stuff. She smiled and told me that was the kind of stuff she was looking for. I had to ask her why and she answered that she could use it for anal sex with her boyfriend. I stopped what I was doing and looked at her. She told me not to look so surprised, that her boyfriend liked to do it up her butt. She asked me if I had ever taken it up the butt, but I told her I didn't because I was afraid it might hurt, even though my husband would like to try it. Katy smiled and said it wouldn't hurt if you just go real slowly. Then she asked for a tube of the lube. I gave her a tube and asked her what she was planning to do with it, and she smiled and said she was going to give me a demonstration. I watched Katy as she walked over to her handbag and pulled out her vibrator and then walked back and handed it to me. She told me to follow her instructions as she slid off her scrub pants and panties. Katy bent over the shipping table with her butt pointing at me. She then told me to grab the lube and spread it around and in her butt hole. I put on a pair of medical gloves and grabbed the lube. I spread it on her just as she had asked. I even gently shoved my finger, with lube on it, up her butt. Katy then told me to take a condom and place it over the vibrator and spread the lube all over the condom which I did. I didn't know why I had to put a condom on the vibrator and I really couldn't believe I was doing this, but the wetness that was forming in my own panties was driving me on. I couldn't believe I was getting aroused by this. Katy then told me to turn on the vibrator and gently rub the tip of it around her anus to relax it a bit. I did what she said and made tiny circles around her anus. After a few minutes she told me to put the tip next to her anus and to very gently push. Karen said that this was the place where you take your time. I gently pushed. Nothing happened at first and then the lube went to work. The vibrator began to slide in. Katy moaned out about how great this lubrication was working. The vibrator kept sliding in until Katy told me to stop and gently pull back on it. It was almost out when I began to gently push it back in again. I could see Katy was enjoying this. With my free hand I reached around and under Katy and began to rub my fingers across the top of her pussy. She moaned out and told me to stick my fingers in her. I began to massage her clit and she gasped. It didn't take long before she was quivering in orgasm. I shut off the vibrator and set it on the table as I stood back to reflect on what had just had happened. I wanted to finger myself right then and there. This was something quiet little housewives don't usually do, or do they? I was brought back to the situation by Katy's voice. She was using paper towels to clean herself up with as she was talking and putting her panties and pants back on. She was telling me how great that had felt. Katy then told me it was my turn. I looked up at her and didn't answer. My mind was numb and I felt confused. She told me to bend over the table. I walked over and bent over and watched as Katy put on medical gloves and pulled the condom off of the vibrator and replace it with a new one. She told me the condoms make for quick clean-ups. I then felt my pants and panties sliding down my legs. Katy had me step out of them. She asked me if I was ready and I nodded a yes. I guess I could have stopped at anytime but for some strange reason I wanted to do this. I really trusted Katy. I closed my eyes as I felt Katy spreading lube in and around my butt hole. Her finger sliding in felt different but good. Katy was being very gentle. Then I heard the vibrator turn on. The vibration on my anus felt so tingly and good. I was really becoming wet. I then felt Katy's fingers rubbing slowly on my pussy. I wanted to feel her fingers inside me and told her so. She began to massage my clit. It was at this point I began to feel the vibrator slowly sliding up into my ass. I was so distracted by Katy's fingers that I had forgotten where the vibrator was going to go. She began to slowly push and then pull on the vibrator. The vibration was making me tingle in places I didn't think could. Katy's fingers began gently tugging on my clit causing me to orgasm long and hard. Katy helped me clean up and get dressed again. This had all happened within my lunch hour. We both quickly cleaned up the area and Katy took the trash with her. I didn't want to leave any evidence behind. My husband and I had anal sex for the first time the following weekend. He really loved it. On the car ride home Katy and I never talked about it, but she did mention she was going to have a sex toy party.
