My wife Tina was a precocious girl, attractive, highly intelligent and with a powerful interest in sex from a young age, and was on the pill by the age of 13. She lost her virginity to her first boyfriend that summer, in the middle of a road! She went on to claim the cherries of all the boys in her class at school. When I met her in her early twenties, she had calmed down a bit. From a personal ad. in Time-Out magazine (the internet dating site of its day) we met and arranged a holiday touring on my new motorbike. In the ad. I had put “Permanent ride for the right girl.” You could take that either way, but in the end, both applied! When we met I was relatively inexperienced in the finer bedroom matters like foreplay but she soon sorted me out. She taught me just how she liked to be eaten and learned what I liked. We used to go hard at it for three hour sessions and had to keep large glasses of water handy because we got so dehydrated from the effort. To keep our sex life hot she would drip-feed me tales of her rampant teen exploits and I would fuck her brains out. She played me like a fine violin for her pleasure. With the kids safely packed off to uni. she told me of her intension to have a bit of extra-marital fun. Knowing her roaming appetite, I had been expecting it and didn't object. She urged me to find a “bit on the side” too, but I never really fancied it. Then I had a health scare. It turned out to be a minor problem but it changed my attitude. Who ever complained on their death-bed that they had too much sex? Tina came into a bit of money and bought a seaside top floor flat in an Edwardian square on the south coast. She decorated it as a love nest. It was painted purple and gold, with an oversized four-poster bed, a swing and framed S&M erotic prints, all in the best possible taste. You can screw with a sea view from every window. She stays there at weekends when she has something planned. She loves finding partners on the internet. I often walk into our bedroom to find her playing with sex toys for the benefit of someone online. Sometimes I give her a hand. Or a cock. We went out to dinner with a swinging couple she met online. Dave was a regular at the flat and I had met Shirley briefly at our London house. They are a little younger than us. She has a great figure and always wears a real fuck-me outfit with high heels, a short lacy dress, push up bra and huge hoop ear-rings. It was arranged that we would meet at the flat for a bit of weekend fun. It would be my first swinging experience. Tina was keen to try DP. She had arranged it before with people she met online but it had never worked out to her full satisfaction. DP is a difficult area for some blokes as it involves two of them getting their tackle very close or touching for DV. They worry that it counts as gay if their balls touch. I told myself that if you have your hard meat in a woman, you are not gay, whatever the rest of you is doing. I watched some bi porn to get used to the idea and to my surprise I found it very stimulating. Does it matter who gives you head before popping it into a waiting pussy? Tina and I had always enjoyed occasional anal and played with toys in our asses. We all arrived at the flat together and as I followed Shirley up the stairs I could see she had no panties on under her signature lacy dress. I am sure she was taking big strides to make the dress ride up for my benefit and I was getting more than a glimpse of her lovely shaved pussy. By the time we got to the flat I had a massive stiffie. After a round of drinks we were all relaxed and I slipped my hand up Shirley's dress to find her pussy warm and juicy. Tina and Dave soon got naked and she sat on his lap, squirming on his cock and getting her ears and neck nibbled, watching us on the sofa opposite. Shirley rocked on my knee as I continued to work on her smooth pussy. I had three fingers in her hole, my thumb on her clit and as her juices flowed down to her ass, I used my little finger to play there too. I lifted her dress so Tina and Dave could get a clear view. Soon we were all naked. Tina and I were fully shaved and Dave was also sporting a full Hollywood. I am a little taller than Dave and we have similar, cut, average sized cocks except that I have a much larger helmet. Shirley took her time exploring all round it and down to my ass with her nimble tongue. I stood and lifted her so she was facing me. She wrapped her legs round me and I let her slide slowly down onto my cock, to let Tina and Dave see it going in. I have a bit of a fetish in that I like to get my cock in without any hand assistance if possible. I think it makes the experience more intense. I managed it no-hands and carried her to the edge of the raised dining area, which was conveniently at waist-height. Shirley could lie back on the thick carpet while I stood and pounded her eager pussy. As I worked on her pert tits with my hands, she put her ankles behind my bum and helped my thrusts into her. Using her legs in that position tightened her pussy round my cock on each stroke and she soon came to a shuddering climax and then another. Dave joined us on the raised area, on his back with Tina on top of him, keeping up a steady rhythm. Shirley knew about Tina's DP desires and moved to the floor so she could get her tongue to Tina's ass and Dave's balls. Meanwhile I was still enjoying her from the rear, doggy style. We had left toys handy and Shirley started work on Tina's ass with a medium vibrator and plenty of lube. This nearly sent Dave over the edge into coming so she had to turn it down. With a final smack of Shirley's buns, I withdrew and stepped up to Tina's expectant ass. No chance of hands-free entry this time! I carefully pulled out the vibrator. Tina slowed down and I applied firm steady pressure to my helmet against her ass. The full length of my cock soon eased into her. Dave started thrusting hard into her pussy from below. I held steady and could feel every movement of Dave's cock through her body. It felt amazing as his helmet swept past mine on each stroke. Dave slowed and I took over the action, my big red balls slapping gently against his. We alternated movement carefully so as not to slip out. Tina was making long low quivering moans and did not respond to questions. Shirley started to massage my back. She worked her way down and started to finger my ass with some lube. I wondered what was next. She had found a small vibrator and slowly entered me with it switched off. I had often wondered what it would be like to be the sandwich man in a bi porn film. She made sure it was in firmly and switched it on. Wow, almost immediately I lost control. I grabbed Tina's hips and had to ram my cock into her wildly like a beast until my cum exploded into her. My thrusts had sent Tina and Dave over the edge too. He shot so much spunk into her pussy that he must have been saving it all week. It finished with all four of us lying back next to each other, laughing and gasping for air. Tina took a cock in each hand, kissed both tenderly and said “Thanks guys”. She helped Shirley to her feet, put her arms round her and planted a long deep kiss on her mouth. I had never seen Tina naked with a woman before and it made my cock twitch as I watched. Dave took Shirley to the sofa for a slow fuck and I had Tina on the floor for slow sloppy seconds. I found it a real turn on to see another couple watching as we all made love. We had another couple of sessions that weekend and must have covered all the angles. Shirley and Dave became regulars at the flat, sometimes with other friends. It was just the start of my swinging adventures with my gorgeous sexy wife.
