"Just an electric device for giving good deep massage," Sue Robin said soothingly. Hell! Surely this sexy-looking woman knew what a vibrator was. But, if she wanted to pretend to be dumb – well, it was part of the game.
Skillfully she played the smooth cylindrical implement up and down the top of Mary Beth's thighs, and in a few moments the thighs slid farther apart and the hips rotated slowly on big round asscheeks like jewel-bearing machinery.
It's getting to her fast, Sue Robin smiled. This and the vodka. A little booze never hurt in a situation like this. Lifting the cock-shaped device, she ran it lightly along the curve of Mary Beth's neck and shoulder, and the woman's smile widened.
"Oh, that's so nice!" She sucked in her breath ecstatically as the vibrations touched all the sensitive areas of her neck, under her ears, and down her shoulders.
Smiling wickedly, Sue Robin slid it down between the big, purple-nippled boobs.
"Mmmmmmmmmmmmmmmmm!" the brunette groaned, writhing on the couch. Her lips parted and twisted, just as her body was twisting. With her eyes still closed, she raised her hands to press her tits inward, enveloping the vibrating cylinder.
Feeling her own temperature rising, Sue Robin leaned over her sister in-law and slowly slid the smooth instrument up and down between the hemispheres of erotic flesh. Mary Beth's breath sucked in with a loud gasping sound and her hips wriggled in wider rotations.
Now, Sue Robin thought. Now. Gradually she drew the vibrator downward across the suntanned stomach, toward the belly button exposed above the narrow bikini panties. She circled the ivory-colored tip around the deep indentation in her belly while Mary Beth's breath came in sharp moans. Her head rolled slowly back and forth on the cushion and her hand remained on her breasts, pressing and massaging them.
Sue Robin's own breath was coming short and fast as she gradually guided the vibrator across the brunette's belly button and downward across the low hill of her belly, toward the top of the mound barely covered by the transparent panties. Mary Beth's thighs were as wide apart as the couch allowed, and now her left leg flexed, dragging her heel upward on the couch.
The vibrator, circled and glided back and forth over the curve of the girl's belly, working steadily toward the mound just an inch away now. Moans came steadily from Mary Beth's throat and, bracing against her drawn-up heel, she rode her ass upward to meet the approaching instrument. Hesitating no longer, Sue Robin eased it under the nonrestricting waistband of the bikini panties and plowed through the furry bush.
"Ahhhhhhhhhhhh!" erupted hoarsely from the writhing woman as the vibrating tip touched her pussylips. She thrust up against it as Sue Robin tilted it downward to rub across her clit. "Ah! Ah! Ah! Oh, God!"
With her own intimate and experienced knowledge of eroticism, Sue Robin plied the vibrator up and down the juicy slit of her sister-in-law, urging her on and on toward an explosive climax.
The brunette's tongue was flicking back and forth over her feverish lips and one hand still squeezed and manipulated a heaving tit, while the other hand plowed wildly through her hair as her head whipped back and forth.
"Oh! Lordy! Oh! Oh! Ohhhhhhhhhhhhhhh! Aaaaaaaaaaah!" Her ass whipped up and down so hard and fast that Sue Robin could hardly control the vibrator, barely letting the bullet-shaped tip slide into the hungry cunt that lunged at it.
Sue Robin was gasping, too, as she felt part of the excitement of the stimulated woman jerking and writhing on the couch. A fine mist of perspiration dampened her forehead, and she felt the juice beginning to flow in her own pussy.
In a moment it was over, and Mary Beth's boobs heaved like mountains tossing on a volcanic eruption as she panted her way back to normal. Not once had she opened her eyes during the whole session.
I hope she doesn't come out of it embarrassed and pissed off, Sue Robin thought as she dropped the vibrator back in her bag. Then it occurred to her that this was probably the first time her sister-in-law had ever got her cookies. She had come close earlier in the day, when Sue Robin had given her the other massage, but she hadn't really climaxed.
This must've been a real block-buster, she thought, looking anxiously at the closed eyes of the other. Mary Beth was breathing normally, deeply, now, and the flush was paling from her cheeks and throat. The long brown eyelashes fluttered and parted, and Sue Robin faced the great brown eyes, glistening with satisfaction.
Mary Beth smiled. "That was wonderful, honey. You're a real miracle-worker. I haven't got a kink left in my body."
Whether she was referring to the muscle-massage or to the orgasm, Sue Robin left unquestioned. It had worked. Leave it be. She smiled back at her sister-in-law.
"Any time, Mary Beth, any time. Now you just lie there and stay relaxed y'heah? I've got to run home for supper or Papa will send the bloodhounds after me." She patted her cheek lightly and sprang to her feet.
In less than a minute she was roaring out of the driveway. "You're a real Girl Scout, Sue Robin," she laughed, then squinted her eyes against the lowering sun as she turned into the highway. "That's one iceberg that is getting defrosted. Fast."
Her father had already eaten and gone back to his office downtown when Sue Robin got home, but Aunt Minerva was still at the table.
"Sony I'm late, honey." Aunt Minerva looked at her beautiful grandniece through wise old eyes, noting the faint signs of recent excitement. "It's all for the cause."
It was dark by the time Sue Robin left the table. She went upstairs to her room and flopped across her bed, but she was stirred by a vague discontent. Giving Mary Beth a going over had gotten her horny, too, and now she felt frustrated. She looked at the telephone on the table by her bed. It would be a simple thing to call one of the young men she knew. A few, a very few had enjoyed encounters with the liberated young woman that they would not likely to ever forget.
Sue Robin had always been very selective, and it had paid off. Not a single man she'd ever screwed had talked about it, something of a record in a small Southern town. Of course, not more than half of her partners had been local boys; thanks to Tyrus' wealth and his generosity, both the twins had traveled as widely as they chose, ever since teenage. Now they were both sophomores in college, or would be when the fall semester in less than three weeks.
The early September breeze, warm and enticing, puffed through the open windows of her bedroom, and Sue Robin sat up.
"Hell!" she muttered. "I'll go for a swim in the river. Nobody's around this time of year," he said.
The tide was stable when she got to the river; no current would be running until the tide changed a couple of hours later. She slid down the short sandy bank to the narrow beach and stood looking and listening for a minute. A tardy seagull screamed in the distance, but no other sound came to her ears. A chunk of golden moon was just getting up in the sky, and its ghostly light was all the illumination that touched the area.
Slipping quickly out of her sandals and shorts and shirt, Sue Robin tested the water temperature with her bare toes.
"Nice," she muttered.
In a moment her bra and panties rested on the little pile of clothes. Poising like a graceful barbarian maiden, she lanced out over the water, hitting the surface in a smooth racing dive. Just cool enough to be comfortable, the water closed about her naked body like a caress. She struck out strongly for the middle of the river, which was a hundred yards wide. On the other side were barren lands.
It seemed ages since she had gone swimming nude, alone or with anyone. Often, she and Buz had gone skinny-dipping, and a couple of times in recent years she had brought some young man who had attracted her strongly down for a secret nocturnal dip in the silent river.
Too bad one of them isn't here now, she thought as she rolled over on her back and floated lazily, looking up at the stars getting rapidly brighter and forming recognizable figures in the early autumn sky. She slid her hand across her belly and downward until it brushed across the wet thicket of hair.
