Nikki loved early mornings; she'd wake, slowly remove her training plug then luxuriously slid a hand into her relaxed ass. It felt so good to be able to self fist herself so easily, and to be able to enjoy the warmth and softness of her back passage enveloping her hand. After a few minutes a self pleasure she'd have to get up, do a few minutes of exercise then take a shower and colonic clean, then a quick dash of make-up and chose her plug for the day. She'd heard Lucy arrive a few minutes before so wasn't shocked to see her naked in the kitchen with Sally and Gill when she walked downstairs; she also wasn't shocked when she was told to put on only shoes, a coat and a smile as they were going out to fuck – slightly nervous yes – shocked no.
Sally had decided it was time for Nikki to get over her reservations about public exhibitionism. Nikki had no problems with performing in a private place, even if it was on cam for the world to enjoy, but she wasn't convinced about doing all that stuff in public places, even if no-one else could see, so Sally was going to sort that, she was nice about stuff like that.
The four made their way to the public library; it was a regular photo-shoot location for them, it had good light, a nice open atmosphere, was public but the shelves allowed them to perform, it also had an accepted "entrance fee". As they walked past the main desk Sally flashed the woman sitting there; she was middle aged, not all that attractive in looks or figure, but she did have a penchant for teen girl pussy which she had made obvious the first time she had caught Sally and Gill naked at the back of the library capturing a few frames for the website – and that became the bargain. The girls could come and use the location, but she'd get first taste of the goods. They all made their way to the usual location around the zoology books then stripped off their coats – Sally, Lucy and Gill comfortably, Nikki with a bit of silent urging – and the librarian arrived to "book them in". About half an hour later and only Nikki was left, the other three girls had ridden the older woman's face and she assumed she would be doing the same until the woman hissed at her to turn round and bend over. Sally had pre-arranged this meet and primed the librarian on what would be most beneficial to Nikki's training regime, so the day plug inside her was quickly replaced by the fist of their host, who used this to pull Nikki back onto her face and keep her there. The anal stimulation was what Nikki needed to take her mind off the location and onto the situation, so she ground her pussy back onto the face of the older woman until she came, which was a nice fluffing for the photo-shoot. The girls erotically posed themselves showing their firm young bodies to the camera, Nikki was fisted again and gaped with everyone being shown running their tongues around the inside of her anus.
Now Sally stepped it up, Nikki was comfortable at the Z's so the girls and their host relocated to the B's leaving their clothes behind, this just left one shelf of books between them and the rest of the library. Whilst the light wasn't as good the risk of being detected was much higher making the situation that much hornier, Sally and Lucy didn't care, Gill wasn't all that bothered, but this was for Nikki's benefit – who was again starting to feel nervous, but again the remedy was nice and simple – destroy her ass. She was bent over, lube was liberally applied and Sally and Lucy went for a double fist. The librarian was openly masturbating at such a horny sight, so when Gill signalled she had the requisite shots she was passionately bent over for the older woman to tongue her ass and pussy. Sally and Lucy kept fisting away, they knew their little bum slut and were waiting for a certain indicator, an action that demonstrated lust had fully taken hold of the sexy brunette so she would be ready for anything; with her ass stuffed with two hands Nikki crossed that line and started shoving back. She grabbed a leather bound book from the shelf and bit into it to muffle the moans of her knee trembling orgasm, juices ran down her thighs which were scooped up by the fisters and fed to the other, and from behind them Gill just about stifled a series of moans as she rammed herself onto the librarians face for her second cum of the day – it was quite a scene which anyone going to get another book could have witnessed, but somehow only the participants were involved. Phase one was over so they extricated themselves from each other, collected their coats and started the walk into town.
The route they used took them through a small park which had a point of interest Sally had spotted a couple of days before, one of the paths was under repair, and the gravel destined to be that renovating medium was in a large pile to one side, cordoned off by six large conical traffic cones. The pile was still there, as were the cones, in fact nothing had happened to the pile or the path, but the cones were about to see some action. Again Sally had prepared the way, and Gill used the alcohol wipes she had brought to clean the tops of the cones, then lubed them liberally. "Ok, here's the game," Sally said to Nikki, "you're gonna get naked, then slide your ass down on each of those cones in turn. You get one minute a cone then we're gonna draw a line on it to show how much you took, but," she continued mock threateningly, "we'd better see an improvement down the line, or your pics won't be going on the web". She was definitely kidding, everyone knew it, but Nikki did love her ass fisting pics being on the web, and she did love her ass being stretched, and she was rather horny, so she accepted the challenge. Now the easy way to beat the challenge was to only take a bit in initially, then lower yourself more and more – Nikki didn't do that. She went for it, forcing herself onto each one and wiggling around to get extra penetration. Sally and Lucy posed naked next to her whilst Gill snapped away, especially the stretched hole at the end of each minute, and the lines marked on the cones got a little lower each time. For the final one Nikki went for it, "help me, force me down" she pleaded and raised one knee. Lucy got close behind her so she could lean back onto her, then put her hands on her shoulders; Sally then took the offered knee and lifted the other, and both girls leant on her. Nikki cried out in pain and pleasure as she was stretched wide open, then Lucy changed her grip slightly so she could lift as well; then Nikki was bounced on the cone, her firm breasts followed the movement, her pussy squirted juices on each down thrust and overall she was having an awesome experience. Gill had captured it all on camera, and now reached between Nikki's legs and slapped her hard on the pussy, it was all that was required to make the highly aroused teen orgasm, and she did so with gusto. After she had calmed down they pulled her off the cone to marvel at the size of the hole between the peach like cheeks of their slut, the game completely forgotten; it was huge, her asshole must have been 5" across which gave the blonde a dirty idea. She ordered Nikki onto all fours then slipped off her shoe and proceeded to foot fuck the brunette, Gill helped out by squirting some more lube onto Sally's foot as the blonde pushed hard, again Nikki's bum was subjected to lovely pressure, but she was already massively dilated and after a couple of hard shoves her foot went in beyond the heel. Sally felt her whole foot – right to the ankle – being surrounded by the accommodating, warm, soft rectum of the bum slut. God it was good, Gill went from lube duty back to photography, capturing the rather dreamy looks on both their faces. Lucy wanted to experience it as well so Sally regretfully withdrew, Nikki enthusiastically presented her ass and Lucy blissfully got full penetration. They were all so horny now, they'd all cum at least twice but their pussies were dripping hot juices and had almost achieved the objective – Nikki was being overtaken by desire – her ass was stretched wide and she was starting to forget that actually she was naked outside performing, and enjoying, incredible sex acts where anyone might see her.
But Sally had one more card to play, the four made their way, flashing each other shamelessly into town, to the supermarket that Nikki used to work in. Sally and Lucy continued to flaunt themselves keeping Nikki at a peak of arousal, "do you think they'd miss 4 apples," Sally asked Nikki, "probably not" was the reply so Sally picked 4 nice firm green apples and removed the stalks. "Coat off, bend over" was then the command to the bum slut, who complied as required. Sally then started inserting apples, the last required an application of lube but was then quickly swallowed by the teens capacious rear passage. "Now show me where people take their break in here", Nikki started reaching for her coat "oh no, you don't need that" said Sally and beat her to it. Nikki couldn't move very easily with the amount up her ass and the effort required to stop from expelling it, but those sensations were part of the pleasure of being a bum slut. "This way" she directed and the four snuck into the warehouse and from there to the break room. There were only two people in there, coincidentally both teen girls, and both knew Nikki, although they had known the previous Nikki, not the naked bum slut who now revelled in the shock displayed on the store girls faces. Sally turned her around, and bent her over, then slapped an ass cheek leaving a nice red palm print "apple please" she demanded, Nikki concentrated and released an apple, hearing gasps of surprise from behind her; Lucy then Gill followed suit, a hard spank then "apple please" to which she complied. She then reached behind her, looked pointedly at the store girls and shoved out the final apple, winked sexily and bit into it – she was now an exhibitionist bum slut.
