When Robbie went off to work he was limping, hunched slightly forward and a little bandy-legged. I'd seen the symptoms once before, the morning after our wedding night when he'd shagged me furiously seven times, so I knew the cause.
Mark was in the lobby getting a morning paper and appearing to be in the early stages of decomposition.
"You're looking a little weary Mark," I chirped. "Overdid the naughtiness, did we?"
"It's all right for you sheilas to sneer, but you don't have to make the same strenuous effort that we do, on the job, I mean."
"The only reason you guys make an effort is because you're always in such a hurry to come in us," I told him amiably, surprising myself with the easy vulgarity of my remark. "That's why women can satisfy so many more partners than men in the same time."
Mind you, if I'd satisfied any more guys than I had during the course of previous day, my pubic mound would certainly be aching as much as Robbie's testes. As it was, I wasn't looking forward to any love-making before that evening.
"So what are we doing today?" he asked. "Vern and Eve are busy with a new group here, so Lisa and I thought we'd have a picnic at a beach somewhere. We've got a four-by-four waggon so we can go almost anywhere. Want to come too?"
"Love to," I accepted, thinking that with both Lisa and I together, his weakened libido would be much less a problem.
We drove around looking over the various coves, bays and beaches until we found a perfect spot, a small bay with rocky headlands at each end and huge shade trees. After a swim, I wore Ronnie's gold thong and the others went nude, we set out our picnic lunch and picked at the food as we drank wine. It wasn't long before Mark's thick dick was hard and horizontal, with Lisa holding it lovingly as she led him down the beach and into the water where they coupled for a submarine 'quickie'.
Within the half-hour he was horny again and Lisa looked at me, then down at his hard cock to indicate that she didn't mind if I'd like to try it.
"It's okay Deby," she assured me huskily. "I'm certain you'll return the compliment eventually."
I felt self-conscious at her assumtion that I would have casual sex there and then, wondering if Mark had told her of our getting things together on the previous afternoon, but assumed he had and slipped my g-string off to take advantage of her offer. It made me feel very close to them both, but probably even more so to her.
"Thanks," I whispered into her ear and pecked her cheek, then slipped my arm around Mark's waist in response to his doing that with me.
He squeezed a buttock and I reciprocated.
"You told her then?" I enquired.
"No, 'course not, I promised."
"Oh," I gulped.
Wading out to chest deep water we embraced before he lifted me by the bum as I guided his cool dick to my willing pussy to enter me. I locked my feet behind his pumping bottom and leaned back with my fingers entwined behind his straining neck to move my hips in meeting his lusty pelvic thrusting, sliding his cock deeply in and out of my love sheath. I abandoned myself to wallow in the voluptuous sensation of illicit sexual play, despite having full approval of both other partners, making sounds that came naturally to me rather than trying to find words to turn him on.
We ground and rolled our tingling hips together in sliding his throbbing member in my slippery sheath, increasing the cadence to a point where our bodies seemed to move of their own volition when we abandoned ourselves to carnal pleasures of lustful sex. I'd no doubt that it was the circumstances which excited me so much; never before having been so thrilled in a sexual contact as I'd been since my first adulterous bout with Mark the previous afternoon. I'd enjoyed accommodating Norman and Vernon as very experienced, older partners, but Mark and Robbie were different somehow; more cuddly and like fluffy toys I suppose.
Mark banged away at my crotch in a very much more leisurely manner than on the previous day, I whispered to him of my enjoyment and affection for him and we became oblivious to the world in our pleasure. As he increased the cadence of his thrusting hips I became more voluble as the spark of my climax became an erotic current through my whole being, ever growing until it exploded in a flash of pure pleasure and a series of hot convulsions had me jerking ecstatically as I clung to his warmly shuddering form.
It wasn't until my senses returned that I noticed five people, two blokes and three women, standing on the beach near Lisa and looking our way. I gotthe impression that two women wanted to leave, our exhibition no doubt, but the others insisted on staying.
Mark and I eventually emerged from the ocean, I'm sure I was blushing, to rejoin Lisa.
"Okay?" she enquired. "You seemed to be enthusiastic about it."
I blushed again. "You heard?"
"Yeah, but don't worry. I like it that you like him too."
We lay about sunning ourselves until I noticed the two of them exchanging secret glances and grinning. Mark made a circle with his left index finger and thumb and poked his right index finger through the gap before moving it rapidly back and forth to indicate coition, raising his eyebrows in a query which she agreed to with a nod. He was hard and horny as they rose to go to the sea hand in hand, waded in and were quickly and very obviously engaged in a sexual union. How did he do it, I wondered, particularly in that he had so recently been suffering both shaggers back and lovers' nuts. I remembered reading somewhere that men are capable of sustained sexual performance with a series of new partners and wondered how long he could keep it up, pardon the pun.
"Hi," greeted a female voice. "Do you lend him out to anybody?"
I looked up to find a nude, fully tanned redhead standing beside me.
"He's not mine, he's hers," I explained. "I just borrowed him to relieve my immediate need."
"She's happy to lend him around though?"
"She only started yesterday," I explained, "swinging I mean."
"So where's your partner?"
"Back in town, at work."
"He a swinger too?"
I nodded.
"Yeah," she said thoughtfully. "My hubby and I have talked about it, but not yet explored it seriously. Wouldn't mind though."
Her male friends had taken off their bathers to display their horniness, but their wives remained modestly clad in their brief bikinis.
"Oh they won't even consider it. Well Paula and Colleen won't," she told me, on seeing me looking their way. "So what do you reckon about..."
"Mark," I put in for her. "Well, there's no harm at all in asking."
"Just like that," she giggled. "Okay then."
And when they returned it's exactly how things went down.
"Hi, I'm Justine. I noticed that your husband enjoys shagging and, due to a great need on my part, wondered if I might borrow him too. I promise I'll reciprocate at the earliest opportunity," she told Lisa. "My hubby's coming down here tomorrow."
"Your friends don't, um...?" enquired Lisa.
"No, wish they did though. Billy and I thought we'd give them a chance to try it with us, but they have consistently refused to rise to the bait. Are you enjoying it? Is it as much fun as they say?" she wanted to know from us.
Lisa and I nodded enthusiastically.
"I'd never have done it at all," I told her, "but having it thrust in my face like that made me consider the matter. My need for sex, not love, was suddenly so much stronger than my desire to be a conventional woman of good moral reputation. I just had the almost overwhelming desire to do something to satisfy that part of me which needed to feel sexually liberated, some might call it slutty and loose."
"We'd talked about it, so it was just a matter of breaking the ice," Lisa told her. "I was a little fearful over the consequences, but without cause, as things turned out. I had a really exciting nooky with Vern and actually found myself looking forward to more in the near future."
By then Mark's cock was at the ready and I noticed Justine glance down at it, then up at Lisa who nodded almost imperceptibly. He stood and drew her to her feet as they joined hands and waded out into the sea where they very quickly got things together with some quite loud sounds of pleasure from an excited Justine.
They seemed to stay in the water much longer than the time at which their voices indicated that they'd climaxed, eventually emerging to rejoin us.
"You slut, you moll," one of her girlfriends spat out as Justine returned to get her towel.
"Don't knock it 'til you've tried it," grinned Justine. "You really don't know what you're missing."
"I don't know how you could," grimaced the other young woman. "A complete stranger."
