When I first started going out with Sara we fucked like rabbits, at least once a day, no matter where we were. On the beach, down dark alleys, fields, woods, almost anywhere outdoors, in the car if the weather was bad. We would try to be reasonably discrete but if we were seen or watched even better. After we married we continued our outdoor activities having many a fuck watched, sometimes by several men, which always got her excited, extra good orgasm guaranteed. All that came to a halt when she got pregnant and the baby was born. It was probably two years before our sex life’s returned to anything near how they had been previously. Outdoor shagging was an occasional treat, on the way home from a night out, having to get home for the baby sitter. Sara stayed at home until our child was at infants, when she got a part time job during school hours. Meeting him from school, becoming friendly with the other mums, one in particular, Naomi who she frequently mentioned. Naomi is about 35, five years older than Sara, and sex mad, at least it was her favourite subject according to Sara. Telling Sara what she'd been up to with her husband and hinting at others, Sara telling her about some of the things we did, mentioning she liked to be watched. Naomi's exploits led to some good fucks for us as Sara retold the stories. Better, Sara started shaving her pussy, something else Naomi did, she'd always kept it smooth before the baby, and was something I liked. She'd always liked sucking my cock but now instead of stopping when I started to cum, she took my spunk in her mouth and swallowed. Naomi had told her she always did and loved the taste advising her to give it a try. I'd never met Naomi but liked her already. When I eventually met her, out shopping with Sara, I liked her even more, attractive, about 5'6”, slim wearing a short dress, great legs, nice tits from what I could see of her cleavage, shoulder length auburn hair. Sara introduced us and as we chatted I noticed her looking me up and down as if appraising me. Towards the end of the following week we were in bed when Sara said she wanted to ask me something. Naomi was having a party, we were invited, she continued there'd be Naomi, her husband and four other couples. Then looking directly at me said “Twelve of us altogether, very intimate, and if we like the others and they like us there will be swapping. Can we go? Please”. This was a bit of a bolt from the blue, but my cock started to harden which she could hardly miss. The first thing that came to mind was “When is it?” “Oh not for another three weeks you don't need to decide yet. But I've spoken to my Mum she'll babysit. It'll be good dirty fun, you might get to fuck Naomi”. My mind was already made up, she was clearly more than keen to go so like a good husband I agreed. Over the following three weeks she told me more, there would be a dinner we would have to serve as first timers a sort of initiation. The day finally arrived we had showered and our clothes were on the bed. She put a dress on and me jeans and t shirt, only needed to get to the house. We had been told to arrive first and greet the other guests at Naomi's detached house. Naomi wearing only a short semi transparent dress watched as we stripped naked, taking a long look at my cock, before taking it in her hand stroking me erect, checking out the goods. The house was screened from the road fortunately as we had to go outside to meet the guests. Completely naked, my prick still semi erect. Showing four dressed couples in, whilst naked ourselves was a strange situation but as the women got out the cars I noticed none wore underwear catching sight of tit and pussy. Once inside we served drinks, mingling with the others who were all friendly as we were introduced. Naomi took charge showing everyone in to the dining room a large table, set for twelve in the centre and we served dinner. Naomi told everyone they were free to touch us in any way, Sara and me both being touched by the other guests, the blokes feeling her tits and fingering her pussy, the women touching my bum, squeezing my balls or stroking my cock until I was hard. Watching Sara pouring wine, her cunt already wet and gaping was enough to get any bloke hard. I served with my cock fully erect, one woman giving me a quick suck, when my prick started to soften as I served her husband. By the time we sat with them to eat we were both highly aroused, my prick standing up erect and Sara's cunt dripping juices.. The meal finished, the table cleared, four men, four women sat at the table plus Naomi and husband Dave. We were standing at one end, ten pairs of eyes watching us, looking around the table some of the women’s dresses were open tits on display, a couple stroking the cocks of the men next to them. Naomi smiled at us then said “Masturbate for us. We want to see you both wank. Nick make sure you don't cum”. Out of the corner of my eye I saw Sara part her legs reaching down and start to play with her pussy, following her lead I stroked my cock slowly until stiff and throbbing, getting a thrill from being watched as was Sara who was enthusiastically ramming her fingers in and out of her cunt. After four or five minutes Naomi got up, and stood behind me, Dave behind Sara, turning us to face one another. Sara's eyes were locked on mine, her tits rising and falling, nipples erect as we waited. I felt Naomi reach round, stroking my cock, her tits and hard nipples poking in my back. My prick erect, Naomi enclosing my cock in her fingers wanking me slowly, Sara opposite me Dave's fingers parting her pussy lips, fingering her cunt with one hand the other cupping one of her tits rolling her hard nipple between finger and thumb. The woman nearest me had unzipped the man next to her stroking his cock, he had a hand between her legs, fingers in her pussy. Naomi was watching Sara who was moving herself against Dave's hand. Still holding my prick she said “Sara, Nick. Get on the table and fuck”. This was the next test, could we fuck in front of an audience. We clambered on and kissed, long and deep tongues in each other mouths. We broke apart and I told her to keep still on all fours and got on my back sliding underneath her in a 69. She lowered her head, opening her mouth taking my prick in her mouth, sucking gently, careful not to make me cum. She spread her legs wider, dropping her pussy to my tongue as I lifted my head, I held her open sucking and lapping her cunt, drinking down the juices pouring from her sex hole, taking her clitoris between my teeth, gently sucking and tugging it, a sure way to make her cum normally. We kept this up for several minutes, I could tell Sara was getting close, the point when she would want to be fucked. She took the lead, she stopped sucking me, got to her knees and moved so she was straddling me, her pussy above my prick. The other guests I could see were now all in varying states of undress, cocks being stroked, tits sucked, none by their own partners and off to one side Naomi standing naked, legs parted with a man sat on the floor licking her cunt as she frigged her clit. My attention was soon back on Sara who was holding my prick rubbing it against her pussy then guided it to her sex hole. I lifted my bum thrusting into her as she moved lower, slamming my cock into her slippery hole. By now I don't think either of us would have cared if we'd been in the centre circle at Wembley in front of a capacity crowd as we fucked. I heard Naomi call out she was cumming and one pair had lost interest in us, concentrating on fucking, but the others were watching closely as my prick slid in and out of Sara's cunt, encouraging us, comments from the men that they'd like to fuck Sara, Naomi claiming first shag with me. We must have fucked for 10 minutes or so before Sara sat up squeezing her tits, playing with her nipples, grinding her pussy on my cock, close to orgasm, the fingers of one hand frigging her hard little clit, gasping out that she was cumming. I thrust in to her faster, unable to hold back any longer shooting by spunk inside her. She sat on top of me for a minute most of the others moving into the lounge, music playing in the background. Naomi and Dave remained along with the bloke who'd been licking her pussy. As Sara moved off me he asked if he could go down on her and lick my spunk from her cunt. As I left the room with Naomi, Sara was laid on her back on the table legs spread with the bloke cleaning her pussy, watched by Dave. Naomi took me through to the lounge where one man was receiving the attention of two of the women on the sofa, another couple were fucking doggy on the floor. Naomi led me to a chair and set about getting me erect again. About ten minutes later I saw Dave leading Sara upstairs to a bedroom where, she told me the next day he fucked three times. The other bloke came into the lounge and joined those on the sofa. Normally I'd take an hour our more to get hard again but with Naomi using her mouth and hands on my prick I was erect in half the time. She'd been a perfect hostess and was the only one yet to be fucked, I'd fingered her, kissing and sucking her tits, teasing her hard pink nipples and she was desperate to feel a cock in her cunt. As soon as I was stiff she straddled me taking my prick straight in her tight wet pussy. With her arms round my neck, her nipples just brushing my chest she rode my cock. Having already fucked Sara I could last, Naomi fucked me hard, rotating her hips, leaning back to grind her clit against my pubes, using her fingers on her clit. She had a shuddering orgasm then feeling me still hard inside her, slowly moving my cock in and out of her cunt she continued riding me using her cunt muscles to grip and squeeze my cock, as she whispered in my ear to cum inside her to give her my spunk. With talk like that and her cunt muscles sending ripples through my prick I emptied my spunk as deeply as I could inside her just as she came for a second time. We watched the others fuck for half an hour or so before she led me upstairs to her bed. We fucked again during the night and again in the morning before going downstairs for breakfast. Sara and Dave were in the kitchen, everyone else had already left. We passed the test because we have been invited back three times since and are going again in a couple of weeks when I new couple may be introduced.
