I'm a 50+ senior scientist who used to work for a large pharmaceutical company. My high position had allowed me to accumulate enough funds to finally say goodbye to the rat race and retire. With my wife Tanya, my 11-year-old daughter Candy and all our belongings we moved out to a so-called 'lifestyle' suburb. A few hectares of prime forest, a huge rambling single-story house with a pool and spa - and peace. After a couple of years of doing almost nothing except having fun, we'd established ourselves in the small community, finding out that we weren't the only ones wanting out. Most of our new friends were in similar positions, and surprisingly, most had children (OK, young adults) of around Candy's age. Pretty soon, Candy had a large group of girlfriends, and probably some boys too, although we never met any of them. It was certainly fun to watch all their nubile bodies when Candy invited them to one of her soon-famous pool parties. Tanya had also made some good friends amongst the ladies, some of whom I found exceedingly attractive and sexy. Some guys seemed to have been luckier than me at finding young wives. Some of the best-looking wives must have been only 25 or so!! Those couples didn't have kids, of course, but they still joined in with the social activities. Not that Tanya was old-looking - she was a beautiful and super-sexy 40-year-old, with a body that she kept well-toned by lots of exercise. It was mainly due to her insistence that most of the other wives also went regularly to the local gym with her. I don't make close friends easily, but slowly I got to know one of the fathers, Ron, who was (or had been) a scientist like me. In fact, we soon realised that we'd met a few times at conferences and meetings around the world. He had a gorgeous young wife, May, who was from Thailand. He'd met her there after his first wife had been killed in a car accident. His daughter, Sara had survived the crash and was, quite simply stunning! She was now Candy's best friend, so I could drool over her often. Ron and I decided that perhaps total retirement was not for us. Eventually we decided to set up a research chemistry lab at my place in one of the workshops away from the house. It took a fair amount of our capital, but with our wives in full agreement, we set up a fully working research lab over a period of 18 months. It should keep us from lusting after each others wives and other females - or so our wives thought! However, what both myself and Ron had been realising was that our age was beginning to play a role in our sexual activity. We'd become close enough friends to discuss this sort of thing and we soon began to realise why we'd agreed to set up this lab project. We wanted to develop the ultimate sex drug - one that would keep us potent as long as possible after each does, and be completely harmless. Intense research of the available studies on chemicals likely to be of use, including Viagra, led us to the conclusion that there was no compound available that did what we wanted. Yes, Viagra worked, but not all the time and not to everyone's satisfaction. We wanted something better and easier to consume, or even for women to slip into their partner's drink when they were in the mood and their partner wasn't - as often happens! We began to synthesise compounds that were very close to testosterone in structure. We made many hundreds of close analogues and tested them all on each other to study whether there was any effect. As in all pharmaceutical research, there was virtually no response from either of our bodies for almost all of the compounds. This study had already taken two years and my daughter Candy now 13 was beginning to blossom out into a real beauty. And her friends were too. It was almost a perfect wet dream for Ron and me to watch the girls enjoying a pool party at our house. Ron's place, which was about a kilometer from ours, was a lot smaller and he couldn't be bothered with a pool. Then one day, around Xmas, Ron noticed that a compound at the beginning of a series we'd just made had surprisingly stimulated him more than usual. He and his wife had had their first sex session for about 2 months and he'd enjoyed some huge orgasms with her all last night. I didn't want to tell him that I'd been having a highly satisfactory affair with his wife almost since the moment we moved into the area. She was almost a nymphomaniac, being ready for my cock anywhere and any time I was available. He persuaded me to try a double does of that compound before we went home for the evening. Within about 30 minutes, I noticed that I had already gained a strong erection, even without thinking about sex. I found my wife lying under a shade beside the pool in her tiny bikini. Immediately rampant in my mind as well as my cock, I quickly pulled her bikini bottoms off, pulled out my cock and plunged it into her wet pussy in a single thrust. I did almost pause to wonder why she was wet, but the feelings of lust that built up in me were overpowering. She groaned with delight and instantly pushed back at me - I guess she did know it was me? I must have thrust my cock in and out of her willing pussy for more than 30 minutes, making her orgasm many times before she asked (or maybe begged) me to stop. And even though I was still hard, there was nothing I could do to get her to continue. "You randy man," she cried. "I can't take any more of that." Her eyes looked down lovingly at my still steel-hard cock. "What made you horny?" she asked, giggling. I wasn't going to tell her about the drug, so I said, "Your beautiful ass, darling!" Tanya laughed as she slipped out of the top of her bikini too and slipped into the pool. I joined her, my hard cock actually making it quite difficult to swim. "Perhaps I need your ass to bring me off?" I suggested. "Or maybe one of Candy's young friends?" Tanya said with a wicked smile. "Maybe!" I replied, grinning. "Which one would be best?" "Now, now!" Tanya laughed. "You're too old to have those sort of thoughts. I'll wank you off if you like." "In or out of the pool?" I asked with a chuckle. Tanya didn't answer. I was leaning against the side of the pool as she came right up to me and grabbed my hard cock. "It's never felt this hard," she cried. "Are you sure you're not thinking about those young girls?" "Well, maybe a little," I admitted, as her delicious soft hand began to work its magic on my cock shaft. We kissed, at first exploring, but then more passionately as I could feel my orgasm beginning to rise. "It's going to be huge!" I cried as we broke the kiss. With a loud groan of pleasure, I felt my cock erupt in the biggest orgasmic feeling I'd ever had. My eyes closed so I didn't see the spurts of cum shoot out, Tanya said later for some distance, into the water. Her hand was still gently caressing my cock as it remained hard, when I finally came down from the intense orgasm. "Wow!" I gasped, "That was really something else!" "It's so good to be able to satisfy you so completely," murmured Tanya. "You earlier gave me some of the best orgasms ever!" At that moment, our daughter Candy arrived back home, accompanied by a couple of her girlfriends. Their chattering alerted us sufficiently to at least get out of the pool and put towels around us. As we went into the house, we heard shrieks of laughter. The girls had stripped down to their bikinis and all three had dived into the pool. "OMG!" cried Tanya. "They'll see your cum!" I could imagine the young girls finding the streaks of white stuff in the otherwise perfectly clear water! Would we need to explain to Candy later? But just the sight of their incredibly sexy bodies cavorting in the water returned my cock to its solid state. Tanya noticed the tent in my towel and giggled. "Are you ready again?" she asked with a giggle. I looked down as I dropped my towel. My cock was as hard as ever. That drug was certainly effective. Tanya grabbed my hand. "They'll be there for an hour or so," she murmured as she reached out for my hard cock with her other hand. She pulled me with her into our bedroom and immediately lie on the bed, letting the towel fall open exposing her gorgeous body to my lust-filled eyes. She spread her legs wide. "Now give me some more of that horny cock!" she urged, watching as I clambered onto the bed between her legs. Her pussy was open and soaking wet, and not just from the pool water. My cock slid up inside her easily and we began to move in a slow delicious rhythm. I felt so good inside her, able to get deeper than usual. The pulled her legs apart, encouraging me to delve even deeper inside. Her orgasms began again very quickly and she began to gush each time, soaking us with her juices. This only made me thrust even harder, striving to give her the best orgasms ever. I was amazed at how well I was able to perform, quite sure that Ron and I had hit on almost the right compound this time. After so many orgasms that Tanya was completely unable to speak or move, I helped her get off the bed and then had her bend over against the dresser. Her beautiful asshole winked at me, but I wanted more of her exquisite pussy. She moaned with delight as I buried back inside her again and, holding her hips firmly in my hands, I began to pound my cock into her as hard as I could, while she moaned and cried with pleasure - very loudly. She orgasmed wetly, her juices dripping copiously onto the floor, and continued to thrust into her. We were enjoying ourselves so much that it was with astonishment that I suddenly caught some movement at the corner of my eye. Not pausing in what I was doing, I turned slightly. There were three faces peering through the doorway, each of them with a sexy grin. "Close the door, Candy!" I called, as her mother exploded into her umpteenth orgasm of that session. There were shrieks of laughter and the door closed. Tany looked round through the haze of her orgasms. "It's OK, she's seen us before," I said softly, pushing my cock even deeper inside her pussy. Tanya squealed, cumming again, even gushing more than previously. "Are you going to cum yet?" she queried, giggling. "Doesn't feel like it," I gasped, still pounding into her. "But I don't want to stop." "You'll have to soon, or I'll be worn out for a month or more." I slowly decreased the ferocity of my onslaught into her still willing pussy. I moved my cock slowly now, deep into and out or her. She orgasmed again, twice, before collapsing yet again, this time onto the floor, with a deep gasp of satisfaction. My cock was still hard and I felt awesomely horny. Part of me wanted to go out and take each of the young girls in turn. But, just at that moment, the doorbell rang. I grabbed a towel and went to open the front door. There was Ron's wife, May, looking deliciously sexy in a little top and tight shorts. She grinned when she saw me in the towel. "Is Tanya at home?" she asked, naughtily, staring at the huge tent my cock was making in the towel. "She is," I replied, adding quickly, "But she's had enough for a bit!" I pulled may quickly into the side room. "Can we?" she asked, excited. "If you want it," I replied, dropping my towel. Her warm hands encased my shaft instantly and she groaned with lust. She hurriedly sank to her knees, pulling my hard cock into her hot mouth and starting to suck it in her usual expert way. I groaned noisily as I reaised (for the 20th time, or so!) that Ron's wife was a real expert at cock sucking. She kept lifting her mouth off from my cock to cry "It's so hard!" and then she continued, until I was gasping with pleasure. While thoroughly stroking my shaft with both hands, she looked up at me, her eyes wild with excitement. "You've never lasted this long before," she exclaimed, immediately muffing her voice again with my hard cock filling her mouth. "Gonna cum, baby," I finally cried, after about 15 minutes of her superb administrations. As usual, May kept her mouth firmly wrapped around my cock as it began to buck and throb, soon sending huge spurts of cum deep down her throat. I cried out noisily, then hurriedly looked around in case either my daughter and her friends or Tanya had come into the room. Luckily our session had gone unnoticed. After some minutes, during which both of us managed to calm down somewhat, May looked up at me, slowly rising to her feet. "That was the best you've ever done me," I grinned. "Thanks," she smiled. "It's always a pleasure for me as an Asian woman to enjoy a nice hard white cock!" I knew what she meant and hugged her close. "It's not going down," she cried, her hands again grabbing my shaft as it pressed hard into her belly. I realised that I wanted her now desperately, despite my several orgasms already. However, I knew Tanya would be back to her usual self again and, although she knew about my affair with May, I didn't yet want to include her in our tryst. "Did you actually want something?" I asked her, laughing. "Well..." she hesitated, "apart from some more of that," she pointed and squeezed my cock, "I came to ask Tanya if she'd like to join me in a girls weekend at the resort next weekend." "OK, I'm sure she would love to. Why don't you go to the bedroom. She passed out after our last session." May giggled. "If you gave her some of that, I'm not surprised. Is it ever going to go down?" "Perhaps. When I've had a third session with Tanya later!" I chuckled. "You randy old man!" she giggled as she walked towards our bedroom, her hips swinging suggestively. I guessed May's pussy was as wet as I'd left Tanya. Perhaps they'd get it on together? I found and put on my board shorts and went out to the pool. The three young girls were all lying around under the shade chatting crazily. They were all wearing mini bikinis, which left almost nothing to my imagination. In fact, when I noticed that Joanne was lying with her legs apart and on her back, I realised I could clearly see the outline of the pussy. There was no need for me to look down to see how my cock was reacting - it was still firmly erect and hard. In order not to involve myself with them, I dived into the pool and began to swim energetically lap after lap. When I paused after about 20 laps, I looked up to see that all three girls were now sitting on the loungers watching me. "Hi, Dad!" called out Candy. "We're enjoying the view!" I just waved back and completed another 20 laps before getting out of the pool. I wrapped my towel round my waist before I walked past them, but I could feel their eyes boring holes in the towel as they giggled wildly. Back inside the house, I was almost surprised to see Tanya and May chatting happily to each other across the bar. Both were sipping wine from long-stemmed glasses. They waved to me as I passed, going to shower and dress again. In the shower, I found my cock was, at last, beginning to soften. Perhaps the effects of the drug were at last wearing off. It had now been more than 4 hours since I took it - not a bad start. I'm sure Ron would enjoy my stories in the morning. That night I slept alone. Apparently I was snoring so loudly by the time Tanya came to bed after watching her favorite mini-series that she went to the spare room to sleep. I have no idea when May left our house. In the morning, Tanya came to me and was clearly disappointed when I couldn't get my cock to erect at all. This was a usual side-effect to this type of drug once its main effect wore off. But I knew I could take more of the test compound later if I needed to. With her and May open and ready for me at almost any time, I didn't think I'd really need it - they would get me so horny anyway. She had agreed to go with May and some other women to the resort for the weekend, leaving me to look after the girls. "Remember, Candy is having several of her friends for a sleepover, so you'll have your eyes full all weekend," she laughed. (continued in part 2) [comments and suggestions to rockyhard4uc@gmail.com]
