Alistair Lloyd sank into the passenger seat and sighed contentedly as his wife, Shula, slid the car smoothly into gear. Her strapless evening gown showed off her well-shaped shoulders, and the tops of her creamy breasts, and Alastair's cock twitched in anticipation of easing it downwards once they had reached the privacy of their bedroom.
They had only been married a little over two years - the second try for both of them - and Alistair was continually amazed, and delighted, by the passion his normally reserved wife revealed, once the bedroom door was closed. Her previous husband, Mark, had died in a car crash, leaving Shula pregnant with Daniel, their only child, and Alistair had the distinct impression that their sex life had been pretty uneventful and that Shula was determined to enjoy that side of marriage to the full, from now on.
Alistair had been the lucky beneficiary of that resolution, and he wasn't complaining! They had spent the evening having dinner with Shula's younger sister, Elizabeth, and her husband, Nigel, and Alistair had to admit that an evening with Elizabeth was definitely calculated to make a man remember what his cock was for.
His sister-in-law's dress had been much more low-cut than his wife's, and she was very generous about bending forward and allowing her guests a long glimpse of her small, but firm tits. Three times, that evening, Alistair had observed a cute pink nipple, and his cock stiffened, again, at the memory. Elizabeth wasn't shy, either, about bodily contact, and Alistair was certain that the way she had slid her hips against his crotch when passing in front of him at the dining-room door had not been accidental.
He didn't think Nigel would be much good to his sexy wife, in the bedroom department. A 'spoiled little rich boy', he was nothing more than a good-natured idiot, in Alistair's estimation, although amusing company. But it was difficult to imagine him slipping the slim, sexy Elizabeth a decent length - hard to see him make her pant with ecstasy and desire. Maybe, one of these days, Alistair might get to know his young sister-in-law a little better ......
Which reminded him ......
"What were you and Elizabeth talking about in the hall, as we left?" he enquired. "Why did she call you 'spoilsport'?"
Shula glanced over at him, quickly, before returning her eyes to the road. Her eyes had betrayed a startled, curious expression.
"Oh, nothing," she mumbled. "It was just one of her silly suggestions." Alistair noticed her fingers whitening as they tightened on the steering-wheel, and his curiosity was piqued. He also sensed an unusual tension in his wife, and he had a feeling it was sexual ......
"What about?" he persisted. "Was it about us driving home?"
It had been suggested, earlier, that they stay overnight with their hosts, so that they could both enjoy, fully, the excellent wines from Nigel's cellar, but Shula had insisted that they return home, and had limited her intake accordingly.
"Yes," snapped Shula, clearly uncomfortable and irritated. "It was just Elizabeth being silly. She had far too much to drink tonight."
Shula was nine years older than Elizabeth, and was inclined to overplay the 'big sister' role, sometimes, Alistair thought. But, clearly, Elizabeth had caught her 'on the raw' tonight.
"Look at her in that dress," Shula suddenly burst out. "And don't tell me you didn't notice, Alistair - I know you better than that! She was practically inviting you in there with her!"
Alistair hadn't realised it had been so obvious to his wife, and was a little taken aback, but he recovered quickly.
"Why would I want to get in there with her, when I'm coming home with you?" he said, smoothly, his hand drifting over to rest on his wife's thigh. Her hand slid down to cover his, and she slid it upwards, nearer her crotch. This was what he loved about her - she could turn so quickly from a respectable, butter wouldn't melt, country lady into - well, something much more earthy. He felt a lot of the credit for that, though, belonged to him.
He pushed his fingers against the join of her thighs, and Shula let out an anticipatory "Mmmmmm."
"Won't be long, now," she said, softly, her hand pulling his deeper between her legs. Alistair imagined her thick-lipped pussy lubricating inside her black thong panties and pressed his middle finger against her crack.
"Steady," she murmured. "You don't want me to go off the road, do you?"
His cock was rigid, now, and he slid his finger up and down the front of her dress.
"You don't fancy Elizabeth's little breasts, anyway, do you?" Shula went on.
"No, I much prefer your big, luscious ones," asserted Alistair, his mind, nevertheless, dwelling on the remembered sight of his sister-in-law's firm pink-nippled breasts. He wouldn't mind getting one of those hard nipples between his teeth, and feeling what lay between those slim, long thighs ......
"Well, that's all right, then," said Shula, dreamily, "because Nigel's little prick wouldn't do anything for me, any more, either."
Alistair's eyes widened - it wasn't like his rather prim wife to use a word like that - even in the bedroom, let alone in the car. Anyway, what did she mean?
The car slowed, and stopped. Shula switched off the engine and turned to him. Her mouth was hot and eager, her tongue pushing into his mouth. He placed his hand gently on the curve of her right breast, and squeezed. She moaned, slightly, and pulled her mouth away. Alistair's heart was pounding - he had never seen Shula so - eager.
"Let's get inside," she said, opening her door. Alistair hurried out of the car and followed her to the empty house. He was glad Daniel was with his grandparents - no babysitter to pay off, and get home. As soon as they were inside, he could ......
Shula entered first and Alistair paused to lock up behind him. When he turned, Shula's fingers were unzipping the back of her dress. She pulled it down to her waist, then flipped the front forward.
Alistair licked his lips as her large naked breasts tumbled forward. Her thick brown nipples were already erect, but she cupped her hands round her tits and flicked them with her thumbs. He recognised the look on her face - it was an expression which she never showed at any other time. It was almost sly - an admission that here was her true nature - the slut, showing off her tits to an admiring audience, turning herself on by sensing the lustful reaction, revelling in it.
He stepped forward, putting his arms round her, dropping his head to take her engorged nipple into his mouth, biting it, lightly, with his teeth. His hands slid down her back to fondle her jutting bottom. Taking a cheek in each hand, he pulled them apart, squeezing each of them, digging his fingers into the firm flesh.
But her little sister was still on his mind. He tried to imagine what he would feel if he had Elizabeth's tight little bum in his hands, at that moment, and his cock told him he would like to know.
Suddenly, a thought flashed again, unbidden, into his mind.
"Any more?" he said. "What did you mean - any more?"
Shula stiffened, then slowly exhaled against his hair. He slowly lifted his head from her breast and looked at her. Her expression was still wanton - but wary. He slid one hand from her bottom, to cup her breast, his thumb rasping across the still taut tip of her nipple.
"I meant," she said, hesitantly, breathily - "Nigel's penis - his cock - it wouldn't do, for me, any more."
"You mean - it did - once?" Alistair asked, his mind struggling to take in the significance of the comment. He knew Shula and Nigel had 'gone out' for a while, but, surely ......
"Well - yes," replied Shula. "You knew that he and I - went out - for a time - long before Elizabeth."
"Yes," Alistair stammered. "But I didn't think that ......" The words wouldn't come, and Shula looked at him in disbelief.
"What did you think, Alistair? Did you think we just - held hands - and kissed a little? Did you think that Mark was my first - man?"
