Sara sat once more on the train, only this time she was returning to school after the most bewildering weekend of her entire eighteen years. She had looked to her mother for reassurance that what had happened to her in the school doctor's office was normal and that she shouldn't be worried about it. Her mother, however, seemed to relish the details of her daughter's experience as they had seemed to reawaken the older woman's long lost desire. And now she was on the way back to school not knowing what to expect from her next arranged visit to the doctor.
As she relaxed back into her seat she looked across the carriage to see the same man who had been staring at her on her last journey. He was smiling at her, just as he had been then, but his smile unsettled her and made her squirm in her seat. He seemed to be able to look deep into her most secret thoughts but, after this weekend, she couldn't even admit them to herself.
After she had shown her mother what the doctor had taught her, the older woman had suggested they go shopping. Sara didn't think she could even walk, her legs were so weak after yet another huge orgasm, but she would have done anything to get her naked mother off her bed and out of her bedroom. So shopping they went.
It wasn't a shopping trip like she had ever experienced before. Her mother took her straight to a lingerie boutique and insisted that she choose and try on some new underwear. She explained to Sara that she was a woman now and the big navy knickers that she wore to school were no longer suitable for her beautiful daughter.
Sara's face burned with embarrassment as her mother described to the shop assistant exactly what she wanted for her daughter and the young woman quickly gathered a selection of the skimpiest thongs and knickers that Sara had ever seen. She picked up one piece that looked no more than a few strings of material tied together with a tiny piece of cotton to cover her pussy.
"You must try that one on, Sara," her mother urged and the shop assistant led the young girl through to the changing area. Sara had never been so embarrassed as her mother and the assistant, a girl of her own age, stood outside the cubicle while she changed. She could hear them talking about her body and how good she would look in the tiny pink thong. Slipping off her jeans, she slid her white knickers down her slender legs and noticed in shock that they were wet again. She couldn't understand how this could have happened. She hadn't touched herself since her mother had left her bedroom and the only emotion she had felt since entering this shop was embarrassment.
She hid her wet knickers in the pocket of her jeans and tried on the new thong her mother had suggested. Sara couldn't believe that she could ever wear anything like this. Apart from anything else, the dark curly hair covering her private place, her "pussy", was far too wild to be contained by such a tiny garment. She left it on but stuck her head out from behind the curtain to explain to her mother; seeing the other girl still there, however, she simply muttered something about it not being suitable.
"Nonsense, Sara; let me see." And with that her mother pulled back the curtain, exposing her daughter to herself and to the smiling shop assistant.
"Oh, I see what you mean. You will have to shave your pussy when we get home but, don't worry, I'll show you how to do that. In fact, we can do it together," she smiled to her daughter and to the shop assistant who was hoping she would get an invitation to the mutual shaving event.
"Now turn around and let me see how it fits at the back."
Sara's face burned bright red as she tuned around and felt the other two women staring at her gorgeous young bottom. She knew that the back strap of the thong had slipped between her cheeks because she could feel it rubbing her dirtiest hole but she nearly jumped when she felt her mother slide her finger under the strap and pull it out.
"It looks great, Sara. Don't you agree, miss?"
The young assistant could only nod in agreement, totally mesmerised by the sight of the schoolgirl's beautiful arse. "I have got to have a taste of that," she thought. She had never been attracted to girls before but this young girl was doing things to her pussy that she had never even imagined and that was just from looking. She squeezed her thighs together, hoping that no-one would notice, as she became aware of a very urgent need to touch herself.
"Perhaps your daughter would like to try another colour," she suggested helpfully and quickly produced a white thong from the shop display that, if anything, looked even smaller to Sara. The poor girl didn't know where to look or what to do as the other girl knelt in front of her and reached up to lower the pink thong. She practically had to peel it off Sara's wet cunt and smiled to herself as she breathed in the unmistakeable aroma of a young girl's arousal.
Mary watched as her daughter silently suffered this new humiliation as the shop assistant slid the pink thong down her smooth legs, and then replaced it with the white one. She wondered if the assistant was paying too much attention to her daughter's private places as she pulled the new thong up then proceeded to run her hands along it to smooth out any unnoticeable creases.
Sara squirmed with embarrassment once again but, even worse, she could feel those strange feelings between her legs again. She had already soaked her own knickers as well as the pink thong, which she was sure the other girl had noticed. Now she could feel her juices soaking a third pair and she knew she had to get out of that shop. She looked pleadingly at her mother who finally took mercy on her and turned to the assistant.
"Thank you, miss. We'll take both pairs. Sara, you had better keep those ones on as I can't see your own knickers anywhere and you've soaked the first pair."
Sara practically ran from the shop as she thought her mother was going to pay the bill, desperate to get back home and hide her shame from the rest of the world. Her mother, however, had other ideas. After a few moments, the young assistant appeared at the door and asked Sara to come back in.
She followed the other girl, Sue, back into the shop and back to the changing area. What she saw nearly caused her to turn around and run back out. He mother was posing in front of the full length mirror wearing nothing but a tiny black thong. Sara could see the back strap between her mother's bottom cheeks but only just. Mary turned when she heard the girl's return and smiled to them.
"What do you think, Sara? Do you like it?"
Sara was lost for words. Her mother was standing there in front of her daughter and a stranger, her large breasts swaying as she moved, her tiny thong barely covering her private place. The summer dress that she had been wearing was hanging on a hook and Sara realised that her mother had not been wearing any underwear, no bra, no knickers, nothing but her linen dress. The woman didn't wait for her daughter's reply but turned once more to the assistant.
"Sue, do you think I could try on a pink one? I'd like to have one the same colour as my daughter's."
Sue ran back to the pile of knickers she had collected earlier and grabbed the first pink one she could find. Handing it back to the older woman, Mary took it with a smile.
"Perhaps you could help me change the same way you helped Sara earlier."
Sue was now the one who was smiling as she knelt down in front of her customer, her face inches from the older woman's pussy. As she peeled Mary's thong from her sodden cunt she could smell another woman's arousal for the second time in less than an hour. This time it was too much and, as the black thong slid down Mary's legs, as Sue noticed the damp spot on the small crotch, as Mary rested her hands on the top of Sue's head, the young girl couldn't help but lean forward and kiss the older woman's pussy.
Mary sighed with delight while Sara gasped in shock. As her mother pulled the shop assistant's mouth to her eager hole, Sara felt as if she had entered some sort of twilight zone. She was standing in the middle of a shop watching a girl the same age as herself licking her mother's private place – and her mother was loving it.
"Oh, God, yes! Don't stop, Sue, don't stop!"
Sue had no intention of stopping as she ran her wet tongue along the length of this sexy woman's hairy slit. Running her hands up the backs of Mary's legs, she grabbed her customer's arse and pulled her closer. Mary purred in absolute pleasure as all the years of self denial fell away. She ground her pussy harder against the young girl's tongue and felt Sue's nose rubbing against her ever sensitive clit. When the young girl began to circle her arsehole with one finger, Mary let it all go.
"Oh God! Oh God! OH GOD!" she screamed.
Sara couldn't take any more of this as she watched her own mother behaving like the worst kind of woman. She saw her forcing Sue's tongue deeper and deeper into her private place and wanted to run away. Only the juices flowing from herself and the weakness in her legs prevented her.
"Mother! What are you doing?" she cried.
"Enjoying all that this young girl has to offer, Sara," her mother replied when she regained the power of speech. "I think you should let her do the same for you."
"What? No! That's disgusting! I can't let another girl kiss me there."
