When they finally pulled into the station in Omaha, they were bone tired and ready to get some sleep, and waiting for them on the platform was their aunt, ready to drive them to her home. As they rode along, Aunt Meg asked them how their trip had gone, how was her sister, and all the other question relatives would ask after a long absence. Even though it was only two o'clock in the afternoon when they got to their aunt’s house, the twins were so tired, Aunt Meg showed them to their room and they quickly fell asleep. At six sharp Aunt Meg knocked on the guest room door and roused the twins form their sleep. "Time for dinner, children," she sang out, "up and at 'em!" Both Zack and Zoey, still groggy from the long trip, came to the table sleepy eyed, but ready to eat a good home cooked meal. After the dinner dishes were washed and put away, the three of them sat down and watched a little television before bed time, until at nine o'clock Aunt Meg announced that it was time for baths and bed! The bathroom was at least twice the size of normal, and was dominated by a huge hot tub that sat over in the corner, already filled with hot water. "Okay, now the both of you, off with your clothes," ordered Aunt Meg! Zack and Zoey paused for a second, looked each other in the eye, shrugged their shoulders, and then slowly peeled off their things. Aunt Meg just stood there with her arms crossed, looking on approvingly at the naked bodies of her young visitors. "My, my," she commented softly, "You two have beautiful bodies, and Zoey, you have very pretty breasts and your vaginal lips are so puffy, and you Zack, you have a very lean and hard body with a much bigger penis than most boys your age!" Both twins turned red when they heard their aunt commenting on their body parts, and even though he was totally embarrassed, Zack immediately became erect while standing naked in front of his nude sister, and the roving eyes of his aunt! "Look Zoey," Aunt Meg said enthused, "Zack has an erection, and look at how large it is!" Zoey had never seen an erect penis before, and even though she felt ashamed, she couldn't help but feel her vagina dampen at the sight of this strange new wonder! Aunt Meg went over to her and put her hand around her shoulder and whispered in her ear, "Do you feel your pussy getting wet, dear, all women feel that way when they see and erect penis!" As she whispered in Zoey's ear, she let her hand slide up and cup the youngster's firm budding breast, squeezing it gently and softly twisting her now erect nipples. "Does that feel good," she asked Zoey, whom by now was beginning to breathe shallowly, as she became more and more sexually aroused! All Zoey could manage to do was nod her head yes, as her vagina became soaked with pussy juice. Aunt Meg then led Zoey to the hot tub, and helped her climb over the side and into the hot soothing waters. It was now time to turn her attention to her nephew, Zack, who was still standing all alone with a big hardon sticking out proudly from his crotch. Taking his erection in her hand, she asked, "Do you ever jerk your cock off thinking about naked girls?" Growing even redder, Zack barely above a whisper replied, "Yes, yes I do!" "That's very good, Zack," she rejoined, "It's good for a you to have orgasms thinking about young naked girls, a young man needs to ejaculate at least once a day to keep himself relaxed, now, get in the tub with your sister so I can bathe you both!" Zack quickly scampered into the tub, grateful to get the chance to hide his raging hardon under the warm water, but what happened next was a total shock to both of them, because right before their eyes, Aunt Meg began undressing slowly, putting on a striptease for the two youngsters! While they were both lean and hard, Aunt Meg was full and plush with just a hint of paunch on her tummy. Her breasts were huge, and they spilled out of her bra and hung proudly with two large nipples in the state of constant erection, while her pussy was covered with a dense forest of brown pubic hair that spread into a large v above her wet slit.
