Susan, age 43, was thin and attractive in a meek librarianish sort of way as evidenced by her ultraconservative taste in clothes, wearing her hair always up in a bun, and quiet mannerisms; much in the classic "Adrian before she started going out with Rocky Balboa" syndrome. Bill was her only son, aged 16. His big turn-on was women puking. He admittted this to a friend of his who knew his mother, and the friend related this to his own mother, who in turn mentioned it to Susan over coffee since the two women had been friends for a long time. This realization sent chills of excitement up Susan's spine because she, in fact, was an emetophile with years of suppressed feelings begging for release but she'd had no choice but to hide her fetish. She'd had fantasies about doing something very "naughty" and non-conservative for a change but felt she could not because after all, she was a mom, and she'd lived in this community for all her life, what would all her friends and acquaintances think? She didn't dare proposition any men for a date of such a nature, yet she needed a release. She needed the kind of male companionship that didn't bring with it the fears of being exposed as an emetophile. What about her son then? It seemed like the only logical choice and she could count on him to keep secrets, and there would be no risk of her getting pregnant if they stuck to anal. She had always liked it better up the arse anyway. One day she had a long sitdown conversation with Bill about things sexual, and during this time she made it known that she would like to share emetophilic sexual encounters with her son since she could not trust any man to keep quiet about her vomit fetish. The ice was broken and it seemed like the perfect arrangement. Susan had always wanted to puke during sex, and her son Bill would finally get to live out his fantasy of having sex with a woman who was puking. They were in the same boat in regards to the need for total privacy. Further conversation brought them to address the topic of the age difference, appearance, ect.

"Bill, what can I do to make myself more physically appealing to you?" asked Susan.

"Well, Mom, for one thing, you could use a little beefing up in your ass and legs. You're on the thin side" replied Bill.

"Okay. I'll eat larger helpings and have rich desserts everyday. What about my hair, clothes, ...?" asked Susan.

"Start wearing your hair down, and add some lazy waves and highlights to it. You have beautiful long hair and I can't understand why you wear it up all the time, so let it hang over your shoulders. Get rid of the old-lady clothes. Guys like to see women in clothes that show off their bodies. Guys like to see big asses in tight pants that separate the butt cheeks, with the seam disappearing between the crack, and a cameltoe in the front. Get some colorful tops, too. Start wearing perfume. Get a suntan. Go to the gym and pump up your legs and glutes. Carry around a walkman and start listening to alternative rock stations and talk like they do. Lose the librarian glasses and get some wire frames. Don't act so shy all the time. Talk louder and laugh a lot. Make jokes. Use slang."

Susan followed Bill's advice to the letter and within six months time she had transformed from the meek, shy old fashioned woman into an awesomely cool and hip chick. To her 5'7" frame she'd added six curvy inches to her previously bony butt, an inch to her calves, and three sexy inches to her thighs. She'd also trimmed two inches off her waist leaving a firm washboard rippled surface, and lifted and firmed her neck, upper arms, and bustline. In short, she now had a body that just won't quit, and the attitude to go with it. Everywhere she went, guys had to do a doubletake and wonder "who's that chick", and she'd hear things to the effect of "yeah baby, swing that cheese" and "oooo, that girl got it goin on!". This was a real self esteem booster to say the least.

"Okay, now am I cool enough?" asked Susan

"Does a bear shit in the woods?" replied Bill. "I can't wait to see you puke".

"About my puke, what turns you on the most about it?" "Tell mommie your dirty fantasies!" said Susan.

"Okay, my fantasy is I want you hot and sweaty. I've smelled the seat of your panties after you've been to the gym and I'd like to experience it firsthand with my nose between your cheeks when you're hot and sweaty like after going without a shower for at least 24 hours. I want you to spread your cheeks apart while you puke, and I want to fuck you in your big sexy ass while you're doing it. I want to put my finger in your sweaty belly button and smell it. I want to drink mouthfuls of your spit when you're nauseous. I want to hold your hair while you retch. I want to see your puke splash everywhere and plenty of it. I want your puke to smell as sick as possible so drink milk and eat something fried so there will be a lot of smelly bile. Let the food sit in your stomach for most of a day so it'll smell more pukey. I want to taste your pukey mouth. I want to hear you burp loudly with my cock in your ass. I want to feel your velvety thighs against mine," replied Bill.

"Wow, that's a pretty tall order dear. This calls for some planning. Why don't we make a vacation of it? Think of it as an early graduation present" suggested Susan.

Susan booked reservations for the two of them at a Hilton five hours drive away from home where she was sure nobody would know them. They checked in, and bright and early next morning they set about their plan. Susan's ultimate smelly chunky puke diet consisted of toast with lots of butter on it, raisin bran, and two glasses of whole milk for breakfast. For maximum sweatiness of her buttocks, she wore her tightest black leather-look pants all day in the 90+ degree Florida heat as they toured the town on foot from about 9am to 7pm. She'd also not bathed since night before last, and she was wearing the same thong panties wedged deeply between the cheeks of her buttocks. The sleeveless top she wore was short and ended just above her navel. Periodically when no one was looking she would stick her finger in it and let Bill take a sniff. The seam of her leather-look pants were also well-buried between the crack, with voloptuous curves obvious on either side and above and below. The legs of the pants also fit her well as indicated by the crease in back where buttock joined thigh. Her thighs were well-muscled and firm with only a thin soft layer of fat which only enhanced the sexiness, and the front displayed a classic cameltoe if one had ever been defined. In the clothes and hot pink sunglasses she wore, along with her fit and tan body and youthful mannerisms, one would have never guessed the pair were mother and son, but rather, a teenaged guy and a slightly older chick on a date. They'd lunched on fried chicken, coleslaw, mashed potatoes, and chocolate milk, and for supper it was steak, baked potatoes with lots of sour cream, salad, rolls with lots of butter, and cheesecake for dessert at around 4:30pm. Then they toured some more. All day Susan could feel the sweat rolling down her legs due to the nonbreathable material of her pants, and her butt turning ranc and sticky, so by now, she thought "My ass must really be yucky after sweating like this all day! He's really going to love it!. And my vomit's really gonna stink with all that dairy and stuff that's been churning in my stomach since this morning. I'm getting horny just thinking about how hard his cock is gonna be".

At nine the duo returned to their hotel room and Susan broke out the bottle of Crown Royal she'd packed along. By ten thirty she'd finished all of it, saving about two ounces for Bill to lower his inhibitions. Susan was giggling like a teenager.

Giggling, Susan, with a proud, drunkenly comical look on her face announced "It's ipecac time!" and with that took the small brown bottle from her fannypack and drank half of it. "For me it takes an hour and a half before I start puking".

Playfully, she began licking Bill's face like a dog, and inserted a finger into her sweaty belly button before raising it to Bill's nose. It smelled like cheese. Bill got her to lie down on the bed as he began licking her tight washboard abs and her navel, unsnapping her bra and working his way upwards to her breasts. She worked her sticky pants off and past her feet, waving the seat teasingly in front of his face, and he caught a whiff of allday sweaty ass-smell, and his cock grew stiff. Susan laid back down on the bed, this time with Bill's hands on her buttocks as they embraced in a locked, tonguey kiss. After an hour of this foreplay, Susan's mouth began to run with spit, copiously. So copiously that she could no longer transfer the liquid to Bill's mouth without some of it running down her face, so she gently nudged his face away from her.

"The nausea's starting. The first sign is when my mouth gets watery like this. Put your ear on my stomach and tell me what you hear" said Susan, giggling.

Bill put his ear against her lean stomach and he could hear the sounds of liquids rushing and churning, getting stronger as several minutes passed by. The sounds came in waves or intervals. His heartbeat raced in anticipation. Two hours passed and Susan still had not puked. She burped many times.

"Shit. Sometimes one dose is not enough to make me puke and I have to take another dose. I don't even feel nauseous anymore" said Susan before drinking the rest of the bottle. "I forgot to shake it before I took the first dose".

Bill sat in the easychair, naked, before Susan joined him, also totally nude. She sat on his left thigh. Bill enjoyed this position and the sensation of a voluptuous, sweaty buttock on either side of his thigh. He put his arms around her waist.

"You've got a really nice stomach Mom. Your abs are really ripped since you started working out" remarked Bill.

Still drunk and playful, Susan said "Put your finger in my belly button and then smell it". Standing to her feet momentarily she then said "Now put your nose on your thigh where my ass was and smell it". Then she sat back down, wrapping his thigh with her warm humid butt cheeks and pussy as before. "Keep rubbing my belly. It feels good". She kept burping and giggling as she reached between Bill's legs with her right hand and fondled his cock and balls.

After 30 minutes the nausea began in waves again, and Susan became more playful, giggling as she verbally inventoried everything she'd eaten that day and calculated the number of hours it had been churning and mixing with bile and digestive juices, also making light of the fact that her choice of foods were such as to stimulate maximum production of smelly bile. As she did this she teasingly clenched and unclenched her hot sticky buttocks against the sides of Bill's left thigh in a steady rhythm, occasionally turning around to transfer mouthfuls of warm saliva with the faint taste of lipstick to Bill's eager mouth. Bill could feel Susan's stomach churn and pulsate against his hands.

Susan then said "I'm ready to go puke now. Let's go to the bathroom". Susan started the video cam and stood naked over the toilet with her hair held in her left hand and instructed Bill to stand behind her with his hands around her and on her stomach. Her feet were spread and so were her buttocks and he felt the warm soft cheeks against his pelvis and smelled the heavy, cheddary sweaty ass aroma wafting upwards towards his face at the same time while he felt the contractions of her stomach steadily increase in strengh against his hands as Susan continued to spit gobs of saliva into the toilet. He slid a hand between her buttocks and rubbed it back and forth before lifting it to his nose. His stiff cock was now inflated to it's full size and he lubed it with petroleum jelly before entering her asshole as she'd instructed earlier. One rule was that he was not to enter her vagina because what if he got her pregnant? Anal was the only foolproof thing to do with a young boy who'd not learned the fine art of "pulling out".

"Put it in anytime you want, I'm open all night" giggled Susan as she bent forward as far as she could, holding onto the flush tank of the toilet with her free hand. She also spread her feet apart wider to give him better access. Bill entered and pumped gently and slowly as per her instructions. Anal sex with a mature woman with a real ass was the finest thing in the world. No skinny supermodel could please a man like that!

Suddenly, with a burp her mouth filled to overflowing with saliva she'd swallowed, followed by a silent torrent of orangeish chunky liquid that smelled like parmesan cheese that rolled over her tongue and washed over the porcelain surfaces of the toilet and wall. This was followed by three more large silent torrents washing out of her mouth and all over the floor beside the toilet. It all happened so fast that Bill didn't even notice until the middle of the second wave. She now looked miserable, weak and sick so Bill pulled out to allow her to squat down in front of the toilet. He knelt down behind her and reentered with his now stiff as ever rod and felt the quick thrusting spasms of her stomach and loins against his hand as she dry retched forcefully with loud "huck", "brick", "ret", and "kawack" noises. This lasted for at least half an hour. By now she was covered from head to toe in perspiration and her face seemed greenish. The bathroom stank with the butyric acid smell of bile and a rainbow of unidentifiable chunks dotted all surfaces of and near the toilet and floor. The sight and smell of the puke, the burpy retching, and screwing a sexy mature chick's big sweaty ass caused him to come. He shot his load so massive and so powerfully into Susan's ass that she managed, despite her sickness, "Awesome" with her chin dripping with puke and some chunks stuck to her face that had splashed up from the bowl. There was so much puke in the bowl that it looked like thin stew or soup and the smell would have nauseated all but the most hardcore emetophile.

Susan instructed Bill "You've just cum so you're going to go soft. Don't take it out, just leave it in me. It feels so good". She continued to retch for ten more minutes. They went to bed afterwards with Susan drifting off to sleep from exhaustion and Bill licking the bitter pukey taste from the inside of her mouth as they kissed and he smelling the ends of her hair that had come in contact with the vomit earlier. Susan was now sleeping on her side with her soft yet firm buttocks against Bill's pelvis, and soon Bill drifted off to a peaceful sleep as he sniffed the hand he'd saturated with Susan's ass smell. Maybe one day he could talk her into letting him fuck her in the pussy. They left the mess in the bathroom until next morning and had another short session of anal sex, using the smell and sight of the vomit still in the bathroom to stiffen Bill's rod. This time, the fantasy involved Susan wearing no panties under a pair of black business slacks with the rear center seam cleverly split to allow his cock to enter her ass, since Bill had expressed it was a fantasy of his to fuck a woman while she was fully dressed. While they were doing this while standing in front of the toilet as last night, Susan bent over and spat in the toilet, burped, and made vomiting noises to add realism. The slit in the back of Susan's pants disappeared into her crevice when she stood upright, so she didn't bother to change into something else as they checked out of the hotel. On the long ride home, as she drove, Bill kept his left hand underneath the opening of the ass of her pants, sniffing it occasionally while his right hand held a ziploc bag containing a pile of tissues soaked with Susan's pukey smelling chunks from the bathroom at the hotel room as Susan made more burping and puking noises while driving to keep him entertained, and more importantly, horny. She had more plans for them when they arrived at home ...
