Scott Birks awoke with a throbbing hard-on. He scratched his bare chest thoughtfully, his fingers working through the thick crop of dark hair which grew in a mat from just below his shoulders. A moment later and he had run his hand flatly downwards over the hard stomach muscles to where his cock thrust stiffly and curved to almost touch his navel.
   He clasped the hard prick tightly, the ache in his balls reminding him of last night and the farewell party. Never had he found Joan Allingham so good at fucking, and he put it down to the fact that it would be the last time the two couples would be able to get together again for some time. Tonight he would be in California where he was to open new offices for Condor Air Freight. It would mean weeks of hard work and trying to find a home for Robin and the kids. Hopefully, it would all be worthwhile, but for the first time he realized how Robin and he would miss Bill and Joan Allingham.
   He clutched his cock and stretched at the same time. At thirty-eight he was in pretty good shape, and he turned his head to where Robin was quietly sleeping beside him, her long ash-blonde hair in complete disarray across the pillow and over her beautifully rounded shoulders. She was lying on her stomach, one knee folded upwards so that the shapely leg was in a loop, the skimpy, flimsy little nightie up around her waist so that her young, curved buttcheeks were completely exposed.
   Robin was ten years younger, and his second wife. Martha Birks had died when Steve had been born, and for six years he had relied on his parents to raise Donna, who was now eighteen, and the boy. Then through Bill and Joan Allingham he had met Robin, found she was a terrific screw and four years ago married her. It was an arrangement which had worked beautifully, and any doubts he may have had about keeping up with a young, sexy stewardess had long ago been dispelled. Not only was she an excellent wife, but she had proved to be a fantastic mother for Steve and Donna, who both idolized her.
   He half turned towards the attractively slender body and feasted his eyes on the curved buttcheeks and the outspread thighs. They were creamy white, and he moved one hand to place it furtively on a rounded cheek, the velvety smoothness filling his loins with a dull, churning ache.
   Robin Birks sighed and rubbed her cheek against the pillow. She ran her tongue across sensuously large lips, coming to briefly before dropping once more into a drifting, hazy sleep.
   He left his hand over the softly yielding bun, his fingers digging gently into the warm, soft flesh. His thumb pressed teasingly near her brown puckered bung, and he could just make out the thin covering of silky pussy hair around the rim of her cunt. The sight brought another surging ache to his balls, and he moved his hand slowly into the small of her back, upwards over her spine and then under the hem of the nightie before reaching around and beyond to her tit.
   Her tits were like large oranges, not large like Joan Allingham's tits, but perfectly rounded, with no sag so that they always stood out as if taunting all the time. His open hand closed in to completely encase the beautiful tit, the nipple scratching his palm as his fingertips closed in around the exquisite base to probe and knead in a series of methodical squeezes.
   "Mnnnn…" Robin Birks was vaguely aware of a dull, soothing warmth as it raced through her tits. The excruciating feel of a man's powerful hand, molding itself over her right boob brought a yearning to her cunt and she cautiously allowed herself to come awake as the hand became more active.
   "Mnnnn… what…" she murmured sleepily. Bill Allingham and she had fucked last night. Then she and Scott had got home and fucked again in bed. Now, as she tried to clear her sleepy head, she wondered if Bill and Joan Allingham had come home with them, too. They had after one party at the Allinghams', and the party had continued the next day. She opened her eyes to find herself staring at the window through which the sun was streaming onto the table by the bed.
   Scott Birks moved his right leg over her left one and slowly eased his knee up into her warm, moist crotch. He pressed against her cunt, listened to her sigh and worked his knee up and down, the exquisite softness of her crotch filling him with lust. "Did you know you have the most beautiful ass in the world?" he asked, moving his cock so that it lay along her thigh.
   "Mnnn…" she murmured. He was cupping the tit now, one finger trailing back and forth over the bulging, fruit-like nipple. She shivered at the response in her aunt, moving her folded knee upwards to give him more room. "Better than Joan's?" she asked softly.
   "Much better." He brought his mouth down and kissed her on the neck so that she immediately cringed, giggled and tried to turn her head and force his mouth away. "That tickles!" she cried.
   His cock was a throbbing shaft, and he moved his knee from out of her crotch, moving it against her outspread thigh so that he could guide his cock to the opening of her cunt. "Does that tickle?" he asked, the aching in his balls almost unbearable.
   "Don't you ever get enough?" she asked, still giggling and waiting for the massive cock to begin its deep plunge up her quivering cunt.
   He slowly thrust it in, the pulsing head widening out the hot tunnel of her cunt as she made little appreciative groans from deep in her throat. "Do you ever get enough cock?" he asked, squeezing the fabulous tit as his cock finally extended itself to the top of her cunt.
   "No," she laughed, arching herself as his hips and thighs finally slammed against hers. "Oooooh…"
   He let go of her tit and moved his hands to her waist, the smooth, velvety feeling of her young body filling his balls with sperm as he held his cock rigidly in. Then he moved his other leg over, mounted her securely as she willingly folded her other leg outwards. A moment later and his hands had lifted her bodily into position, his thick, bloated cock thrusting and recoiling as she cried with delight at each deep thrust.
   She flung her head the other way on the pillow, his powerful thrusts making it difficult for her to breathe. They rarely fucked this way, with him behind, and she found it strangely exciting. She cupped her tits, squeezing them and stroking the nipples at the same time. Then she grabbed the pillow and pulled it under her, down to her waist so that she was curved over with her shapely young ass bare and exposed so that a moment later she was crying out and whimpering as his big, hungry cock swept in and out of her grasping, boiling hole.
   "Jesus but that's good." His hands left her waist and he was leaning forward and reaching for her tits. She moved her hands and let his take over. When they did, he pulled and milked at them as he steadily fucked her.
   "Sensational!" She was gasping for breath and straightening her legs at the same time. "God, but it's heavenly."
   The boiling jism was bubbling in his balls. He was sinking his excited cock to the hilt each time, her pouting cuntlips clasping at the base of his shaft with each deep plunge.
   "We… we… we should do this… more often."
   "I'll say." He thrust his dick in and held still momentarily.
   "God, yes." His cock filled her entire twat. It was as if it were reaching for her tits, and she gave a groan of despair as the thick, heavy prick throbbed and pulsed at the apex of her cunt.
   He knew he was coming and he tried to hold on. He released her beautiful firm tits, hoping that would assuage the ache in his balls. He grabbed at her hips, withdrew his cock once more only to find the familiar surging of his cum had started. Then he held her beautifully curved buttcheeks in place and slammed against them in a frenzy of delight. "Yes… I'm… I'm coming!"
   "What a… fuck… fuck!"
   The force of the ejaculation surprised them both. The magnificent head of his cock belched forth in a spasm of volcano-like explosion, the hot, boiling sperm striking her cervix and making her shiver and tremble in response. She gave a series of half-choking cries, her fingers grappling wildly at the sheet and mattress as she tried to spread her legs wider. Then she lay there, her mind fighting oblivion as his thick cock plunged hungrily in and out of her gulping, clutching cunt.
   He rolled off the warm, silky softness of her body. "Jesus, what a fuck," he gasped, his powerful chest heaving and falling as he fought for breath.
   Robin Birks lay quietly gasping, her face turned so that she could watch him, her eyes dropping to the wet, shimmering shaft of his cock. She reached out and clasped it, the warmth of the sticky tool bringing a surging warmth to settle in her aching cunt. She rubbed it several times, her eyes focused on the red, gleaming head as it bared itself each time she sank her little fist to the bottom. "I'm going to miss it," she murmured, as if talking to herself.
