My wife's best friend lost her husband to a heart attack. Debbie had been on her own for nearly two years. Then my wife asked me if I could do a few repairs for Debbie, joking that Debbie herself might need a bit of servicing. I wasn't sure if my wife was actually offering me her best friend or just joking. Debbie was a good looking woman and I had often wondered what making love to her would be like as I masturbated. Debbie was 41 and I was 43. She had long dark hair that hung just below her tits that were a nice size. She always wore long skirts, sometimes with long splits up them. Saturday my wife dropped me at Debbie's house along with a lot of tools, then went off shopping. First Debbie had me look at a tap that was permanently dripping. She had a pair of replacement taps and luckily there were stop valves that allowed me to complete the task in about 30 minutes. Then the downstairs toilet wouldn't flush. The oval link wire that connected the handle to the flush mechanism had rusted through and broken. Again Debbie had spares and it took just ten minutes to fix it. Next was a shelf that was coming away from the wall. Several new rawplugs and longer screws sorted that out. Then she said that she was unable to pull one the drawers out from under her bed. She showed me that the other three all pulled out, but the last one was stuck. As Debbie pulled on the drawer her skirt split open allowing me to see her pink panties. I couldn't help myself as my cock twitched as it flooded with blood and within seconds was rock hard. As Debbie moved away to give me access to the drawer I was sure she noticed my unwanted erection. I could see something in the drawer stopping it from opening. With a thin long screwdriver I managed to dislodge a cardboard tube and the drawer opened. Debbie removed the tube telling me that it contained poster pictures that her husband collected. She then shut and opened the drawer several times as I stood my cock was just inches from her face. Then she stood telling me there was just one last problem requiring attention. There was a small leak from the plumbing under the the kitchen sink. She also told me that the water was slow in flowing away. On inspection the u trap was partially blocked so once Debbie emptied the cupboard with a bowel below it I dismantled all the plastic piping. The trap was blocked with fat and rubbish. It was soon cleaned free as was all the other pipes. I was on my back reassembling the pipework when Debbie suggested putting the kettle on and making a cup of tea. I agreed before I realized that Debbie was about to run the tap. Before I could say something I was soaked. Debbie quickly shut the tap off, but for me it was too late. As I slid out of the cupboard I could see right up Debbie's dress. This time, I couldn't see her panties as she had removed them. I could see her pussy lips dangling and the bush of dark pubic hair just above them. My cock once again sprang to attention. As I stood, Debbie said let me help you with that as she dabbed my tee shirt with a towel. "Take it off," Debbie said, pulling my tee shirt off and throwing it into the tumble dryer. There was no way that she had not seen my erection tenting in my jeans. Apologizing she was drying the water up in the cupboard. Once dry I climbed back in the cupboard and finished reassembling the plumbing pipes. As I slid out of the cupboard, Debbie was straddled my body and as I cleared the cupboard I could again see straight up her skirt. Then Debbie pulled her skirt up and as she sat down on my face she said," Just one more thing to service." Then my face was covered by her fanny. The fanny that I had wanked thinking about many times. I wasted no time in sticking my tongue into her wet pussy. She tasted good, and she was moaning as I ran my tongue along her crack and circled her clit over and over again. Her hands were undoing my belt and trousers, eventually releasing my cock from it's confinement. She was licking the head of my cock for a few minutes before sucking it deep into her mouth. I came quite quickly and Debbie swallowed the full load. Then Debbie climbed off me and taking my hand led me back to her bedroom. This time I was on top as I sucked her pussy and she sucked my cock again. It was a while but my cock started to rise again and Debbie was struggling as I was pumping her mouth and throat with my cock. Pushing me off her she got into the doggy position and insisted that I fuck her long and hard. I was soon sliding my cock into her wet pussy and plowing her with long hard strokes. Debbie was groaning with each thrust. Then she came, groaning even louder and thrashing her head around as her body shook. As she came down from her orgasm, I rolled her onto her back and slammed back into her pussy. As I resumed pumping her pussy I undid the front of her dress to get to her tits. The tits that had also filled many dreams. They did not disappoint me as I fondled the large firm orbs. Debbie was wailing as she approached another orgasm. As I sucked a nipple into my mouth, Debbie groaned her way through another orgasm. Her legs were twitching while she came. I continued pumping away at her fanny. Then Debbie was building to another orgasm. I lifted her legs up and put her feet over my shoulders, enabling me to slam even harder into her pussy. This time I went with her and pumped my cum deep inside her pussy as she shook her way through her orgasm. This was new for me as my wife only ever came once in a session and then put up with me pumping away until I came. Debbie told me that she was had always had multi-orgasms. "I must start making my next list of repairs required," Debbie said with a devilish grin on her face. A while later we showered and I fucked her again in the shower. Debbie had two more orgasms before I pumped a second load inside her hot pussy. Then I dressed and with my dry tee shirt from the tumble dryer was ready to be picked up by my wife. Debbie kissed me as my wife parked the car. Then after loading my tools into the car, we were on our way home. "Did you do the repairs and service Debbie, " my wife asked. "Of course," I answered, still not sure if my wife was joking or not. This happened three years ago and about every four months or so, my wife tells me that Debbie needs another servicing and takes me and my tools around to Debbie's. To this day I do not know if she is joking or she knows that I am fucking the daylights out of her best friend. I have no reason to tell my wife the truth and ruin a good thing so I am happy to leave well alone.
