A couple of days later Sally received a call from an unknown number, "hello?" she replied, "hi" came the response rather nervously "it's that girl from the supermarket". There was a slight pause for courage then she barrelled on, "I'd love to have sex with you, but I need to talk first – meet me out back of the supermarket in half an hour", and she hung up. Well Sally was kind of tied up at that moment, literally hand-cuffed to the wall with a spreader bar between her ankles, so that Gill had been the one to hold the phone up to take the call, but she was eager for the meeting. Gill gave her ass three more hearty whacks with the paddle, pulled out the anal beads slightly faster than normal and gave a couple of tugs on the chain connecting the nipple and clit clamp; then said "well, I guess we'd better get going then". She removed the restraints and the clamps, leaving Sally momentarily feeling dejected until she received a hard slap on her aroused pussy; then they slipped on some shoes, put a coat over their naked bodies and walked out to meet the new girl.
Amazingly they were on time, arriving just as she walked out of the back door of the supermarket, then following her towards the bin area for a little more privacy. She looked longingly at the two girls, and more importantly at their bodies as neither had gone to the effort of doing up their coats. She went for it, "I'm Nikki, and I love bum sex". "We do too" responded Sally; "no," countered Nikki "I really love, I fantasise about it all the time, I want to be the biggest bum slut in the world; I want to have the largest, slackest bumhole ever, I want to be able to take ANYTHING up there". Sally got it, with her it was exhibitionism, it wasn't about receiving immediate pleasure, it was the concept, the fantasy, the thrill – it was brain sex – she slipped off her coat then faced Nikki, "we'll make you into the biggest bumslut ever, but you will do everything we demand of you". Nikki nodded her agreement as the importance of her decision struck home, "so let's see this ass of yours" continued Sally. Nikki turned round and dropped her trousers and panties displaying the full, firm globes of her backside; "bend over then" commanded Sally and Nikki obeyed without hesitation. Gill, now also minus her coat, provided assistance by pulling apart the cheeks to the maximum presenting the twitching asshole to the blonde; who quickly sucked on her middle finger then drove it all the way into the willing bumslut. Nikki stiffened in a mixture of pleasure and pain, throwing her head back with mouth wide open in a silent scream. Sally knew instinctively that Nikki was sub, moved forward and roughly cupped the sluts face pulling it to face her. "This is just the start," she whispered ominously, emphasising it by withdrawing her middle finger and shoving it back it with another beside "you will see us every day for your anal training, and you will deny us nothing", and so it began.
Every day she reported for her training – as was delighted to find that it wasn't just Sally and Gill that would be her tutors, all the girls played the role; her ass was used and abused as she desired with a regular routine of flushing, stretching and penetration. She had fingers, toes and tongues; dildos, vibrators, speculums and butt plugs; carrots, cucumbers and cherries all shoved up her. She was also introduced to all the other forms of sex the group enjoyed – some were wonderful, some were initially degrading – all had the desired effect on her pussy. She initially found exhibitionism difficult, but just like her anal training experience helped, so she was able to "comfortably" join in the filming of her training for the web. Toilet sex was another acquired "taste", and there the feeling of degradation definitely helped, she was a natural submissive but quickly was becoming an enthusiastic participative submissive. The girls, especially Sally and Lucy, threw themselves into providing a proper education, so it wasn't long before Nikki felt the thrill and pride at accommodating her first fist, and thankfully captured on camera was stunning orgasm she experienced as her ass stretched just enough, then closed around Lucy's wrist. Lucy then started to pull out knowing full well that it was even more pleasurable having your ass stretched from the inside out, before driving back in. One of the key points of the lessons focused on depth, width was great but depth is often overlooked so Lucy greased up her forearm and started to shove. Nikki was feeling fuller than ever as a hand made its way up her rectum, it was delicious they way her body reacted around the object and made all her anal fantasies justified, and just spurred her on to do more, so it was only a couple of weeks after her first fisting that she received her first double. This was a pre-arranged event with Sally, Gill, Lucy and Miss Moulton; it was being streamed live by webcam and filmed directly, and Nikki was determined not to disappoint. As the session began Nikki adopted an ever such a cute but incredibly dirty position on all fours as Sally and Lucy began greasing up their hands and the target hole of their protégée. Sally began stuffing fingers into the willing back passage of the sexy little brunette, then pulled out to allow Lucy to take over; back and forth they went opening up the anus until Sally's left hand slid in. Almost immediately Lucy started working her right hand in along the wrist of the blonde; Nikki now went down onto her elbows, then shoulders to shove her ass further into the air grimacing with the pain all the time. After several minutes of hard work Lucy joined Sally inside and the two held hands surrounded by the warm, soft, accommodating rectum of the teenage bumslut. Nikki couldn't believe and was dying to see the pictures when Gill joined in; she had a lovely, thick phallus strapped over her crotch which as the two fisters moved apart she shoved into the sopping wet cunt of the girl in front. It was certainly a shock for Nikki, two hands up her ass and 8" of latex up her cunt and she took the predictable course of action available to her – she orgasmed hard. This wasn't enough for Gill though, she was horny, the air was filled with hot girl smells, the strap-on was rubbing her pussy as she moved, so she maximised the effect and fucked the hell out of the brunette, she fucked so hard juices were spraying out each time she shoved in and running out each time she withdrew. Sally and Lucy were also having a ball, as their combined double fist was wider than Nikki could stretch they were fucking in and out, with each attempted withdrawal distending the anus of the now thoroughly exhausted Nikki.
Sally, however, wasn't going to let it end there. She got Gill and Lucy to pull out, then lubed up her arm further and went for depth – hard. Nikki gasped as she felt a hand drive deep into her rectum, really deep, it didn't stop – Sally just kept pushing up to her elbow and slightly beyond. Lucy had one hand massaging Nikki's clit, but put the other underneath her belly, there she clearly felt the hard impression of Sally's fist on the inside and let a yell of surprise and pleasure – Nikki however was enjoying too much pleasure to even make a sound, her head was swimming and her ass was full – perfect.
Finally Sally pulled out and all the girls stood over the upturned bottom of their anal slut marvelling at the gape they had achieved, and almost wondering what to do next until Lucy came up with a plan, "foot fuck" she said simply. Nikki dropped her shoulders fully to the ground and reached back with both hands to pull her ass cheeks apart further, then the girls took turns in grinding a foot into the back passage of the bumslut; she wasn't experienced enough to be able to take a whole foot past the heel, although one day she would be, but that didn't stop the girls from trying and she adored being stretched. When each had enjoyed her ass she demonstrated that she'd been doing some homework – keeping her cheeks apart she squeezed back at the hole and prolapsed her rectum. Her teachers all moaned with desire and fell upon her deep red rose, Lucy and Gill licked and fingered in it turns, but Sally had the best idea – she opened her mouth pointing her tongue before shoving it into the now tight bum hole, then closed her lips over the rest of the rectum and began to move her head up and down in a perverted cross between a tongue fuck and a blow job. It was a great ending to the evening.
