My wife asked me to go to our daughters house and have a look at her electrics as they were suffering the mains tripping out at various times. I had a few days off and I rang my daughter to tell her that I could take a look in Tuesday morning. Elisa told me that she would be at work, but Danni may be there. I had long suspected that my daughter was gay as I had never seen her with a boy or man. Then my suspicions were amplified when she started to buy a house with her friend Danni. Elisa told me to use my wife's spare key to let myself in if Danni wasn't there. I rang the doorbell several times without any signs of movement, so I let myself in and went to the cupboard under the stairs to start testing. I had all the fuses out and was testing for any high or low resistances and straight away I could see almost a short circuit. I put my tester back on to the offending wires and went to crawl out the cupboard. I was stopped dead when I saw a pair of legs next to me and on looking up I could see the smallest pair of panties that I had ever seen and over that was a baby doll nighty. I had a good look before finishing getting out the cupboard. Danni was a really sexy little thing and I had often imagined her in bed with another woman. My mind couldn't put her with my daughter. As I stood I could see down the top of the baby doll and the swell of her boobs looked very inviting. I had met Danni before so she knew who I was and she had obviously just remembered why I was there. She offered to get me a cup of tea. I told her that I would be upstairs starting to try to locate the problems. I went to the first bedroom. I guessed it was Elisa's room as there was some of her clothes on the bed. I couldn't see anything of Danni's in that room. I tested the sockets and they tested ok as did the hairdrier and rollers that were still plugged in. I thought I should tell Elisa that she should unplug when not using them. The fault was elsewhere. I checked the socket on the landing and that was OK. So I walked into the other bedroom. Imagine my embarrassment to see Danni in it in just a very small pair of panties. She had started to get dressed. I quickly shut the door as I heard her laugh. My beliefs were confirmed, Danni really was a sexy little thing and to that end she had my cock stretching my jeans. I went down stairs and waited for her to come down. When she did I apologize to her for walking in on her dressing. She just laughed and said, "See anything you like?" I just gave a coughed and said I was going to check the sockets in her room. I was in there for just a few moments when she joined me. She had two double sockets in her room. The first had a TV and seperate recorder plugged in. The other double socket was behind the bed, after I pulled the bed out I discovered it had far more appliances plugged into it. The sockets had a triple sockets plugged into each of the sockets and off them were six other devices. I followed the cables. There was a heated blanket on the bed, an alarm clock, a separate radio, a set of curlers, a mains driven vibrator and a Sybian. For anyone who doesn't know what a Sybian is, it's a saddle for the lady to sit astride and it has a dildo that penetrates the woman's pussy while the mounting vibrates against the woman's outer pussy parts. I could feel my cock getting hard and my face going red. Danni just watched as I unplugged each one and then tested the socket. The socket was fine. It was one of the devices plugged in that was the offender. I told Danni that it was one of the appliances. I could see that she was also going a little red. I had tested the clock and the radio and was testing the heated blanket when Danni told me that she rarely ever used it, it tested fine. I must admit that I thought with her in bed with you who would need additional heat. Trying to avoid the two items that would embarrass I went for the curlers. Unfortunately they tested fine. That just left the vibrator and the Sybian. I went for the vibrator and that also tested fine. I connected my tester to the sybian and straight away it tested faulty. I almost swallowed my own tongue as I informed Danni that it was the Sybian. Danni cried, "Oh no that's my favorite. I could feel my cock pulsing and the redness in my face imagining her sat on it with it throbbing away inside her. "Can it be fixed," she asked. I told her that I would take a look. I started to undo the base from the sides and discovered that the top didn't come off with out removing the dildo and the rubber surround that would press into the woman's fanny. I could feel my cock getting harder and my red face become even more flushed. I could see Danni smile as I held the dildo that had probably been in her pussy many times, especially if it was her favorite and pulled it off and then removed the surrounding rubber. The top then came off with ease. The fault was obvious. It was a wire that had vibrated free and was touching the casing. I pushed it back on, and after connecting it to the mains and replacing all the fuses in the fuse panel, I tried the Sybian without the case on it. It buzzed very loudly and I could see the wire working it's way back off. It needed a new connector. I crimped the connector to get as tight a fit as I could, but every time it was turned to full speed the wire worked it's way off again. I crimped it one more time and told Danni that until I could fit a new connector she couldn't turn it above half way. She looked pleased, but also disappointed. Pleased it worked and could be fixed, but disappointed that until I could do it she couldn't work it hard. I started putting it back together and was soon replacing the rubber surround and then the dildo on the top. I turned it on to make sure it was still working. Before I could turn it off again Danni said she needed to see if it worked ok and with that she stood astride it and hoisted her skirt and pulled her panties to one side and lowered herself onto the throbbing toy. She sort of growled that it was ok. Then she was pulling herself off of it leaving her glistening pussy juice on the dildo. I was still sat on the floor where I had been testing and fixing it. Danni took a step towards me and grabbed my hair and pulled my face to her pussy. Here was a young woman the same age as my daughter offering me her pussy. My tongue reached out and touched her clitoris. Danni squealed at the contact, and then moaned as my tongue licked along her slit and then sunk into her pussy. Danni was now moaning every few seconds. I had to free my cock as it was getting painful as it pressed into the material keeping it restrained. Danni pushed me off her and away as she climbed onto her bed. She looked so damn sexy laid there with her panties rucked up to one side of her pussy. I got up and then reached for her panties and pulled them down and off of her. As her legs opened again I positioned myself between her legs and groped her shapely breasts . Danni was obviously impatient as she grabbed my cock and steered it into herself. Then as I started to pump her lovely tight pussy I mauled one of her tits and with my other hand held her head as I could thrust my tongue into her mouth. I was trying to pace myself but all the while Danni was trying to dictate the speed and wanted it faster than what I was giving her. Eventually I caught up with her and we were banging hard and fast together. The kiss had long been broken so we could gulp enough air in as we banged away at each other. Then Danni's pussy was gripping my cock tighter than before and she was groaning loudly as she came. I could not hold on any longer and pumped my cum into her pussy. We lay locked together for several minutes before I could roll off of her. "Wow you're good for an old man," she informed me. I told her she wasn't bad for a young girl. We laughed. As we lay there I told her that for some reason I had thought she was gay. Danni laughed and said that she swung both ways, but always preferred a good stiff cock. As she said that she reached out and held my cock that was pretty limp. "Shame," she declared "It's far too soft." I suggested that a good sucking always rectified that. Well that's just what I got. Danni spent the next five or so minutes sucking my cock back to health. Then she rode me like she did her Sybian. We came at the same time and Danni was laid on top of me for several minutes before she eventually climbed off. After I finished packing my tools away, Danni insisted that until I had completed the full repair on her Sybian I would have to come and service her pussy. I repaired the Sybian with a good repair the next day. Even with the Sybian fully working Danni still rode me to a good orgasm and I fucked her again a while later in the doggy position. Even with the Sybian in good order we fucked about once a week for nearly a year when she told me that we had to stop as she was getting married. About three months after her wedding she called me and told me her Sybian needed servicing. There was nothing wrong with it, what she wanted was a good fucking and our affair resumed. That went on for a good seven years when she fell pregnant. To this day I often wonder if her son was mine. Then I had the chance of promotion and move away to another office or take redundancy. I looked hard at the money and opted for redundancy. By selling our large family home and moving near the coast left my wife and I fairly comfortable. Our daughter, Danni and her husband sold their house and moved to a much bigger house a six bed house that they split almost in half. At the same time our daughter married her boyfriend. I visited them a few times on my own and stayed in their spare room. When everyone was out Danni would sneak into my room and we would fuck like teenagers. The last time was almost four years ago. I was hoping that her Sybian needed more repairs, but the call has never come and since then my daughter and husband have always visited us. This is because Danni now has three children and Elisa and Joe have a baby boy, so we have more space. If anyone out there has a Sybian that needs servicing, I'm your man.
