Date: Thu, 18 Oct 2012 18:00:52 +1000 From: Jason . Subject: Elizabeth's Bottom Training - Part 4 Part 4 "..97..98..99..and 100...very good girl...," said a pleased Dr. Michelle, as she helped a sweaty and horny Elizabeth for the fifth and final time to lift her thoroughly stretched out bum receptacle off the obscenely big black shiny training cone she had just obediently - although at times requiring the firm guiding hand of Dr. Michelle - bounced her big beautiful butt up and down on exactly 500 times. "Urhnnn..," groaned out Elizabeth in a kind of open butt gasp, as her almost numb, but wonderfully stimulated back entrance was removed from deep on the cone and splayed fully and pervertedly open for the doctors scrutiny. Elizabeth could feel the full extent of what the long slow gradual stretching session had done to the still relatively quite tight and proper little rear opening she had arrived with - leaving it as an enormous gaping cavity flushed with a sexy red ring around her relentlessly worked looking, forcibly stretched-out sphincter. "Oh wow...her bumhole is really coming along nicely..." said Elizabeth's clearly impressed mother, seeming delighted by the sight and progress of her daughters unnaturally stretched out anus - having only just been able to rejoin her daughter's third session due to an unexpected call away. "That's it, good girl...lets show mummy what a big loose play hole you have," said the doctor, as Elizabeth assumed the now quite familiar head down - bum up position on the vinyl training table, while the doctor pulled the girls glossy oiled up cheeks apart so Elizabeth could easily let her stunningly dilated anus gape to its full extent. "Looks like someone's had a busy little bottom today," said Elizabeth's mother, disappointed that she had missed most of the session, but pleased by the state of her daughters bumhole and how willingly and enthusiastically she had taken to having it expertly and thoroughly violated. "She certainly has...her bum had quite a full schedule today...didn't it sweetie?" said Dr. Michelle, as Elizabeth looked back towards her big shiny oiled rump and nodded with a cheeky little grin on her sweaty flushed face. Elizabeth's mother couldn't help but beam with maternal attraction for her pathetically cute looking daughter, whose large fleshy rudely exposed behind, contrasted so perversely with her short little girlie pigtails and squeaky clean white tennis shoes and socks that adorned her clumsy looking feet. "Today she did a fifteen minute session on the bike, then we practised stuffing techniques before Elizabeth got to have a nice long ride on the training cone," said Dr. Michelle, taking size measurements of Elizabeth's nicely expanded smooth red ring. The sessions were definitely turning out to be money well spent, thought Elizabeth's mother to herself as she watched the highly recommended proctol therapist, expertly handle her daughter's backside. "Ok I just need to take some photos now, but I don't have any more sessions for the rest of the afternoon, so I was thinking if you'd like we can extend the session and do a bit of extra work on Elizabeth's bottom?" suggested the doctor to Elizabeth's mother, while preparing the camera for the usual end of session photos. "Yeah ..I think she could probably do with some more work on her bottom today...don't you sweetie?" asked Elizabeth's mother in a sweetly rhetorical way. Elizabeth looked up at her mothers smiling 'yummy-mummy' face and nodded happily in agreement, even though she knew it meant preparing herself to have her already hour-long used back entrance, once again filled. "Aren't you a lucky girl, getting to have your bum used repeatedly" said Elizabeth's mother in a cheeky but sincere motherly way, as she twirled one of her daughters pigtails playfully. "Uhn..huh..," cutely sighed the 21 year old Elizabeth, biting the corner of her lip innocently. "Ok I think we'll move this thing over to the examination chair now and do a bit of pumping work on it," said Dr. Michelle, deliberately and teasingly only referring to Elizabeth's bottom. Dr. Michelle carefully helped Elizabeth off the table and walked her across the room to a large, high set, almost horizontal reclining padded chair. The chair was only long enough to accommodate Elizabeth's back and head, with her thighs and upper backside just sitting on the edge. The examination chair also had elevated foot stirrups and looked to Elizabeth like the kind of thing she had seen in her gynaecologist's office. "Ok sweetie, just lie back for me now and make yourself comfortable," said the doctor, as Elizabeth lay back down onto her back, while the doctor took the girls thick athletic legs and lifted them up into the stirrups and strapped her white tennis shoes securely in place. Next the doctor carefully adjusted the position of the stirrups and Elizabeth's position on the chair, so that the girls legs and backside were spread fully open, giving the doctor unobstructed access to the big winking puffed out, bumhole in front of her. Leaving the vulnerably positioned girl and her mother at the chair to wait in anticipation, Dr. Michelle went over to a cabinet and removed what looked like a long clear plastic cylinder with a thin hose and rubber squeezing bulb dangling from the end, much like the one on the black stretching ball the doctor had previously used on Elizabeth. Elizabeth felt a giddy flutter in her stomach as she starred in curiosity at the strange looking device the doctor brought over towards her, wondering what exactly she was planning on doing to her ready and waiting, vulnerably open bottom. Without saying a word to Elizabeth, the doctor got straight down to business, first running her gloved hand briefly over and around the girls slick, greasy hole, before taking the long plastic tube and placing it down between her Elizabeth's legs. This time instead of feeling something pushing on and trying to enter her backside, Elizabeth instead simply felt the cold plastic rim of the open end of the cylinder press down against the skin around sphincter. "Ok Elizabeth, nice relaxed breaths for me now...," said Dr. Michelle, making Elizabeth slightly apprehensive about what was in store for her. Elizabeth's mother felt her daughter squeeze her hand a little tighter, as Elizabeth felt the skin around her sphincter tighten a little as the doctor held the tube in place and took her first few squeezes on the attached air bulb. Elizabeth gasped ever so slightly as her body adjusted to the new sensation. The doctor squeezed a few more times, then a few more times again, as Elizabeth started to feel her skin little by little being pulled taut into the vacuum pressure of the cylinder - creating a sensation of suction. Steadily Dr. Michelle continued the bursts of pumping until she had created a nice strong vacuum seal around the girls anus. As Dr. Michelle let the girl get accustomed to the new feeling, Elizabeth remembered the doctors instructions and took some steadying breaths before she the felt suction become a little stronger, and the sound of the bulb once again being squeezed. The tight pulling of her delicate skin into the suction of the cylinder was at first a quite strange feeling, but not particularly uncomfortable or overly straining for Elizabeth. But as Dr. Michelle continued to work the pump the pressure began to slowly build on Elizabeth's anus as the oxygen was drawn out from the air-tight tube. Elizabeth softly moaned as the pressure of the air vacuum started to pull tightly and suck on the skin around her sphincter, pulling it taught and outwards. Elizabeth took some deep breaths and tried to steady herself, as she rapidly felt the self control of the muscles of her anus begin to give way to the unrelenting suction, that - to the girls surprise – had even started to draw out the soft plump inner flesh of her anal passage. "That's a girl sweetie, just relax and let it come out," said the doctor, as she watched pleased by the sight of Elizabeth's rosy red inner anus beginning to emerge from her wonderfully elongated opened hole. Elizabeth's face contorted into a cute pout as she strained and tossed her head back and forth, trying to deal with the intense throbbing and sucking sensation of having her bumhole methodically drawn out of her. Elizabeth's mother did her best to help ease her daughter's obvious discomfort, but couldn't help but show her pleasure at getting to watch her daughter's anus being forcefully but carefully prolapsed from her big beautiful bum. With a look of focused medical discipline on her face, Dr. Michelle used the pump with proficiency as she expertly teased the usually hidden innards of Elizabeth's orifice out into the tube. Elizabeth could only softly huff and groan as the air continued to be extracted from the plastic cylinder, that was being filled out nicely with Elizabeth's slick rosebud. It was definitely quite a guilty turn on for both the ladies to see the squishy red plump protruding anus almost looking like a pair of big fat lips kissing up against the sides of the tube, while Elizabeth squeaked and grunted as she felt her inner bum being rudely and unstoppably pulled out. "Nnh..Ohn...I don't think I can take any more mummy...," whimpered out Elizabeth meekly, as her prolapsed bumhole was pulled out to almost three inches outside her body. "Yes you can young lady...," said Elizabeth's mother, running the back of her fingers gently across her daughters slightly pudgy cheek and giving her a look that Elizabeth had come to know well over the years. "You just need to be a big brave girl and let the doctor finish working on your bot-bot...don't we sweetie pie...," said Elizabeth's mother, in a firm but loving way, as she grinned encouragingly at her daughter. "Mmhm...yes mummy," girlishly squeaked out Elizabeth, appreciating her mothers firmness as she let herself accept the unnatural but admittedly indulgently sexy feeling. Understanding the girls obvious strain, Dr. Michelle rubbed Elizabeth's stomach soothingly and let her have a short respite, before recommencing the intense pumping on towards the non-negotiable goal of giving Elizabeth her first fully prolapsed asshole. Just over a minute later Dr. Michelle was finally satisfied with the progress of the pumping and released the pressure of the suction. Much to Elizabeth's guilty relief, Dr. Michelle removed the tube from around the girls elongated anus and surveyed the results, grasping the big fat juicy, lube glistened anus in her hand and gently playing with it, before giving it a gentle nudge back into the girls bottom - causing Elizabeth let out a deep sigh of well earned release. The sensation felt quite strange to Elizabeth as her anus slipped back into place, but with her sphincter muscles feeling incredibly relaxed and loosened. It was that relaxed and loose state that caused Elizabeth to only let out a slight gasp, when Dr. Michelle easily and assertively thrust her whole hand, wrist deep right into the temporarily pillow-like curtains of Elizabeth's inviting bumhole. After only a second or so of filling Elizabeth's backside with her hand, the doctor thrust back out in one smooth motion - slightly shocking the girl with the rapid filling and emptying of her hole. Dr. Michelle continued penetrating Elizabeth this way, making a sloppy slurping sound each time her hand re-penetrated back through the almost floppy - temporarily play-ruined slit. After nearly a dozen more rapid in-out – almost punch like penetrations of Elizabeth's wonderfully relaxed and rapidly sexually maturing bottom hole, it became clear to the doctor from the big dirty girlie...unmistakably slutty moans coming from Elizabeth's wet open lips, that she was definitely a young lady in need of a good long hard anal fisting session. Elizabeth's large smooth backside and thighs glistened with sweat and oil in the bright lights of the room, as the doctor's pumping rubber covered hand slid easily in and out of the hole a few more times, playfully toying with the hugely dilated opening. "Hoh," fluttered out Elizabeth, as she felt the doctor finally settle her hand fully inside her backside and hold it there, giving Elizabeth a well stuffed feeling and a sphincter that tingled with tension. Using her well practised professional skill and technique, Dr. Michelle then begun using her balled up fist to give Elizabeth a slow and sensual full butt screwing. "This is what's called fisting darling," said the doctor, slightly increasing the pace and force of her twisting hand and wrist. Elizabeth's mother smiled broadly as she tugged lightly on her daughters pigtail - keeping her contorting face up nice and high, while she enjoyed the sight of the doctors whole rubbery hand disappear into her daughters bum. "While toys are very important to your therapy, it is also necessary for a young lady like yourself to receive regular anal fisting," said Dr. Michelle, who's clinic also catered for many female clients who paid good money to have their needy bottoms given a good hard fisting. "Ahunh..ahunh..." sighed out a heavily panting and flushed Elizabeth, as the fisting settled down into a nice steady stuffing of the girls stretched-out and greedily accepting butthole. "Mmm...your really enjoying that aren't you pumpkin...," enthusiastically suggested Elizabeth's unashamedly turned-on mother, as the erotic aroma of her daughters sweet pink spread open and creamy vagina wafted into the air. "My big dirty girl loves taking it up the butt, doesn't she...," Elizabeth took her mother by happy surprise, when she gave her reply by urgently taking her mothers hand from her cheek and bringing it to her lips, where she passionately took her index finger into her mouth and begun to suck on, like it was the most wonderful thing in the world. Elizabeth quickly moved on to the middle finger, taking it deep and coating it with her smooth saliva, before hungrily taking her mothers ring finger into her pouting lips, guiltily tasting her wedding ring as it passed across her wet lips. Elizabeth's mother was needless to say quite delighted by her daughters sudden ravenous display of affection and loved how intimate and sensual the incestuous finger sucking was. "Thank you mummy...Uhn..., I'm so happy you made me do this...I love getting it..Orhnn..up the butt...I really, really dooo..." Sincerely stammered out Elizabeth, through the moans and groans of her incredible first anal fisting. "I know you do sweetheart and I have a big surprise for you when we get home...," said Elizabeth's mother referring to the reason she had needed to leave the session earlier. Elizabeth was intrigued but far to busy being solidly fisted to ask questions right now. Moving the girl over onto all fours, the doctor commenced giving Elizabeth a good hard fist pounding from behind, until the girls throbbing, sopping wet vagina could take no more and in what was becoming a slutty little habit of hers - exploded in a torrent of gushing juices, making a thoroughly nasty little mess everywhere. The two ladies grinned satisfactorily at the sweaty, well used mess of a girl as she collapsed contentedly onto the table, still proudly sticking her butt into the air an unashamedly showing off her sore but satisfied, sloppy gaping asshole.
