The situation was suitable now. Bobby Lee lay flat on his back on the sand, moaning first with frustration, then with mounting ecstasy as Sue Robin flicked her tongue tip rapidly up and down the shaft of his engorged cock. Like a tiny jackhammer her tongue pecked along the bulging tube on the underside of his shaft, up to the sensitive cord joining the head, and back down again to his balls.
He reached a hand down to stroke her hair. Maybe it was true what they said about twins, he thought. Maybe they were mind-readers of each other. Sue Robin knew just exactly where to touch him and how much pressure to put on and he groaned as she touched a particularly sensitive spot under the rim of his cockhead. If only Mary Beth would develop this art.
Sue Robin rounded her lips in a tight ring and forced them down over his bulging cockhead. Down she went until the knob blocked her throat, then slowly she came back up again.
"Ah, Sis, that's great!" he sighed again. He wondered vaguely if she would go ahead and suck him off. Sue Robin always managed to spice their excitement with a little uncertainty. He never knew exactly what she would do next. But it was always wonderful. He slid his fingers around her ear and gently poked his little finger inside. He knew she liked that, especially when she started getting hot herself.
With long deep strokes she went all the way down until her lips almost reached the base of his thick shaft. Nearly as acutely tuned to his feelings as he was himself, she felt the first throbs that signaled he was about to come. Bobby Lee relaxed, content to blast his load into her warm moist mouth, but suddenly she slid off him and rinsed her head. At the same time she clamped her fingers expertly around the rim of his cockhead, her thumb jammed firmly against the cord under the flange.
"Hold it, buddy," she chuckled. "I want some of that action."
As soon as the throbs subsided, she released his cock and sprang to her feet. In a second she had stripped off her shorts and was straddling his hips.
"Nobody's going to miss out tonight," she panted, seizing his cock again and stroking the head along the slot of her cuntlips. She felt the moisture of her cunt anointing the satiny knob which was already wet with her saliva. Spreading her outer lips with her left hand, she guided the tip of his cockhead upward until it stroked lightly across her clit, and a spasm shook her graceful body as the sensitive little nub sparked its sensations up through her belly.
"Oh, baby, that's good! How long has it been, Buz honey?"
His only reply was a groan of deep delight. Sue Robin was on top of the situation in more ways than one, and he was content to let her take charge. She had never failed him yet.
She titillated her rampant little clit for a few moments more with his cockhead, until she felt herself thoroughly juicy.
"Now!" she gasped. "Now, honey!" With her weight on her knees, she posed her arched-back body over him while she centered his rod tight against the slippery inner lips of her pussy. "Aaaaaaaaaaaaaah!" she sighed as she sank down, feeling the broad head wedge the walls of her eager cunt apart. Down to the very base of his shaft she went, until her asscheeks rested on his thighs.
She sat motionless, getting her breath again. Reaching behind her, she felt for his come-filled balls and softly massaged them between her smooth fingers.
"You've got a beautiful dick, Buz," she said. "A beautiful dick." Tightening her asshole, she made her inner muscles squeeze the entrapped pole like a hand squeezing a cow's tit. Sue Robin was a well-read girl and she had a healthy curiosity about everything, especially sex. So when she'd read a girl friend's book in high school about the "magic muscles" in a woman's vagina, she immediately set to work developing her own vaginal muscles.
Now she clamped and relaxed the velvety sheathed bands in her love-tunnel, and Bobby Lee groaned in ecstasy. If only Mary Beth would learn some tricks like that, he thought. Her pussy had been tight enough, but completely immobile, like the rest of her unresponding body. But the delicious massaging he was getting now washed away that other unpleasant memory.
"I'm gonna ride your ol' love-muscle to a fare-thee-well, Buz," Sue Robin warned, and suiting action to words, she rose up slowly, tensing her strong leg muscles.
As she rode back down, still slowly, her well-lubricated cunt made a slushing sound around the piston filling her snug passage.
"Oh, that's so good, so goooooooooood!" she gasped, pulling aside her unbuttoned shirt and squeezing her firm boobs.
Bobby Lee squirmed his hips, trying to match the slow rhythm she was establishing with her rising and descending buttocks. Reaching forward, he caressed the inside of her spread thighs, then slid his fingers into the upper crevice of her pussy to stimulate her clit. He found the rubbery protuberance easily from long practice, and lightly massaged it with his fingertip. He knew that Sue Robin liked a gentle rocking of her little man in the boat. Too much pressure, and it turned her off. "Ohhhhhhhhhhh, Buz, that feel perfect!" She arched her head back, facing up at the night sky, and little cries of passionate joy rippled through her tense throat. Releasing her tit, she ran her hand through her hair.
"So hard!" she groaned. "You're so hard!" Her movements became more rapid, more violent, and soon she was plunging her ass down hard, but the shock was excitingly cushioned by the pneumatic padding of her asscheeks.
"I can't – hold – it – much – longer!" Bobby Lee stammered, thrusting his hips upward to meet her downward lunges.
"Let it go! Let it go!" she sang out. "Oh, let it go!" Her movements became a wild gallop as she slammed herself up and down on his swollen cock, jerking to the first tremors of her climax.
"I'm coming, honey, oh I'm coming, coming, coming!" A series of little yelps broke from her gaping mouth, and her head whipped back and forth, whirling her hair out in long swirls.
All his pent-up frustration seemed to blast out with his sperm as Bobby Lee turned loose his load inside his sister's hot cunt. Burst after burst erupted through his aching rod and her body quivered with each change.
Abruptly she shot her legs out straight behind and fell flat on his body, to gasp out the rest of her climax. Her hot breath funneled into the hollow of his neck and shoulder, and he felt her heart pounding through her shock-absorbing tits which pressed resiliently against his broad chest.
As his breath slowed back to normal, he reached down along her hips and up to caress her plumply curved asscheeks. She lay quietly, breathing deeply as his hand dipped into the crevice between the two mounds of warm flesh, sliding easily in the valley which was lubricated by her love-juice and his overflowing sperm. She was so exhausted that she barely quivered when his fingertip poked mischievously into her tightly puckered but juice-filled asshole.
"That's one we haven't tried yet, Sis," he said. "Not now," she said languidly. "I can't take any more now. Some other time."
CHAPTER TWO
Sue Robin sat in the living room of the new cottage, watching her sister-in-law arrange some late-blooming flowers in a vase.
"Bobby Lee's gone to Atlanta on business," said Mary Beth, her huge brown eyes carefully avoiding those of Sue Robin. "He said he might be gone a week."
Sue Robin knew that already. At breakfast that morning her father had rubbed his balding head impatiently and rumbled, "I be dawged if I can figure that boy out. Hell's bells! With a brand-new wife like his'n at home, I'd be right there Johnny on the spot, not traipsin' off to Atlanta. Business can wait a few days. But he acted like he wanted to get away. More coffee, Clarinda!" he bellowed over his shoulder toward the kitchen.
