"Let's go to bed." Robert said matter-of-factly, as he stood up, and started pulling his light cotton shirt over his head, exposing the hard muscles of his stomach. He had read the look in his mother's eyes and was ready to relieve the boredom of the long trip with a little family orgy. He had it made, and he knew it. He was the nominal head of a household containing two good-looking women who were as sexually free as he was. The problem of incest, he had long ago dispensed with and looked forward to making his incestuous sexual bouts international.
"Are you tired so early?" Marie asked her son with the lilt of friendly teasing in her voice.
“No. Just horny," Robert shot back with a practiced casual tone.
"You could be a little more subtle instead of just standing there with your muscles hanging out and giving orders," Suzanne put in as she folded her magazine and threw it on the little table next to the train's closed window. Actually, she was relieved that the issue had been settled and she could stop worrying about the feelings that were making her crotch itch. Now she could look forward to the relieving of the sexual tension that was mounting steadily in her young body.
Dropping his shirt onto one of the two beds in the compartment, Robert looked down at his sister and smiled. "Come off it, Sis, you know damned well that you're just as randy as we are."
"What makes you so sure?" Marie interjected. "I haven't agreed to this group session yet, and you might have asked me if for no other reason than that I'm your mother."
"I know you too well," was the only reply she got as Robert undid his belt and then sat on the edge of the bed and pulled off his loafers, letting each one drop to the carpeted floor.
"You might at least put those away so that we don't stumble over them in the middle of the night," Marie flared slightly but not really caring, since her need was growing and she could feel her lubricating juices running thick and hot in her pussy. She didn't wait for a reply, but started to pull off her own clothes so that she wouldn't have to wash wet panties. Leaning over, Robert picked up the carelessly dropped shoes and placed them under the table out of harm's way. "Come on, Suzanne, don't be modest, it's all in the family."
"Don't get your ego trip going too much," Suzanne chided, "I might have my eye out for a little strange action now that you all have introduced me to some of the more rewarding pleasures of life."
"Whatever's right," Robert said as he shoved his pants down his strong legs and pulled them off. Taking his mother's cue, he carefully hung his pants and shirt on a hanger in the small closet of the compartment.
Marie had shrugged her way out of her jersey blouse and folded the light green fabric neatly before placing it in her suitcase. She was wearing a wispy bra that was transparent, and she knew that her nipples were hardened and poking tightly against the thin fabric of the skimpy bra. "Undo me," she said to. Robert as she spun around playfully on the ball of her foot, presenting the long curve of her back to his view Working with deft fingers he unhooked his mother's bra, letting it fall free. "How 'bout you, Sis?" he said, turning to his sister.
"Oh, come on. You know very well that I don't wear one," Suzanne said as she tugged her sweatshirt up over her head, exposing the perfectly shaped mounds of her young, ripe breasts. Reaching out, Robert tweaked both her nipples between his thumb and forefinger, making the tips stand up like sharp points.
"Cut it out, damn it," she riled at him, but not really meaning it. She was always amazed at the speed at which her body reacted to any sexual stimulation. All someone had to do to turn her on was look at her with bed in his or her eyes and she was all aflutter, her juices starting to run and her breasts swelling with desire. She had tried to fight it when Robert had first started sneaking into her room at night, but then she learned that he was also making it with her mother, and she figured that she was a slut just like her mother and stopped thinking about it. Besides, she reasoned, sex was fun and accepting that took care of a lot of mental anguish.
"Don't tease your sister," Marie admonished Robert as she pushed down her skirt and panties with one swift movement, having already disposed of the loosely hanging bra.
Turning to face his mother, Robert saw her lush body, still young and vibrant. His eyes glued themselves to the small triangle of dark, curly pubic hair that covered her sexual mound. He happily recalled the many times during the last year that he had buried his face there like a rutting animal to suck the juices from her and gain sustenance. Other scenes flashed before his mind's eye, times when he had been gazing up as she had lowered herself to his waiting mouth, her head thrown back, mouth open, with the passion of a wild thing, raw and brutal, seeking his lips on the very center of her womanhood. Hastily, with mounting excitement, Robert pulled down his cotton shorts and tossed them on the opposite bed. His prick sprang forward with the full hardness of youth. His body was ready and he threw himself down on the bed, stretching out in the middle to wait until his sister was ready.
Marie, now completely nude, her body pulsing with desire, climbed onto the bed and settled herself next to her son's prone body.
"Come on, Sis, what's taking you so long? You said you don't wear underclothes, but you're always the last one ready," Robert complained as he inserted his arm under his mother's shoulders and pulled her head closer to his own.
"Go ahead and start without me. I never knew you to wait anyway, so what are you complaining about?" she replied, pushing down her jeans and bending over to pull them free of her feet. Kicking off her canvas shoes, she turned to the bed, and watched as her mother ran her hand down the length of Robert's stiffened prick, gripping its base and pumping it slowly.
Suzanne had been ready to deliver another biting remark, but when she saw her brother's prick standing tall and strong, clenched in the determined fingers of her mother, she forgot what she was about to say and kneeled on the carpeted floor next to the bed. She knew what was expected of her and she set about to carry out her task.
"What do you want me to do, Mom?" Robert asked, turning his head so that he could look directly at his mother.
"Just keep it hard," she said crisply as she rolled to her side and got to her knees.
Robert knew what was coming so he folded his hands behind his head and waited patiently for the fun to start. He was going to get it his own way tonight because she was hot and wanted to lead the action. It wasn't always the same, but whoever was hottest usually got things started and the others followed their lead.
Feeling his muscles convulse under her lips, Marie kissed her way down her son's belly, letting her nimble tongue lave at the tender surfaces of his skin. She wasn't worried about Suzanne, who was still kneeling at the side of the bed, because she would pick up on the action without being told. Suzanne could always be counted on to fit herself in where it was necessary. Clearing her mind, Marie held Robert's prick in her gripping fingers, stroking it and squeezing the thick shaft.
Straddling his legs, Marie held her son's cock steady while her mouth descended, her lips opening to engulf the rosy-tipped head, her tongue licking the rubbery surface. Her breath came sharply as she breathed deeply, taking in the air through her nose, the nostrils distending. Her loins convulsed as she felt the heat from his cock invade her mouth. As she sucked at his root, she felt hands sliding up her thighs pushing them further apart, and she knew that Suzanne was fitting her body into the action.
Lying on her back, Suzanne wiggled her body until her head was directly under the dark bush that marked her mother's cunt. She saw the glistening hair that covered the pink lips of Marie's cunt. She knew that Marie was hot and ready for the intrusion of her tongue. Circling her mother's hips with her arms, she pulled her head up and let her tongue flick out, its point wet and slick. Parting the lips of Marie's cunt with her tongue, Suzanne savored the sweetness of the juices that ran in profusion from the channel which split her mother's crotch.
