The obese 22 year-old earns up to £130 a week and hopes to become one of the biggest names on the 'supersize big beautiful woman' scene. But shockingly, rather than being appalled by her career choice, her mother Dorothy, 50, has given Caitlin her blessing and even acts as her photographer.
"I love the way I look and I started actively putting on weight because it makes me feel sexy. My speciality is to rub and shake my belly for the camera." Incredibly - despite being a dress-size 24 and having a BMI of 80 - the healthy range is 18-25 - Caitlin insists she's healthy and has check-ups several time a year with her doctor.
She said: "My blood pressure is athletic perfection. But I do get out of breath going up the stairs or walking short distances. "If my health became badly affected, I'd consider slowing down. But I love what I do and I have no plans to stop." Despite Caitlin's expanding waistline, her mum - who works with special needs children - is surprisingly happy to encourage her unusual career.
She said: "I'm her mum and I'll support her whatever she wants to do. If this makes her happy, that's fine by me. I think she looks beautiful in the photos. "I take some pictures and advise her on which photos to use. "I do worry about Caitlin's health but she goes to the doctor for check ups and seems to be fine. "There's nothing wrong with what she's doing - she's not showing off her boobs or private areas, it's just her curves.
"I'm proud of her and as long as she's happy with her career, it's fine by me." Catlin, who performs under the name Calico Bombshell, grew up with her mum, dad, and younger brother Blake, 17, who is slim, in rural Kentucky. By the age of seven she weighed 8st 7lb after gorging on fatty foods common in the South like corn dogs and macaroni-and-cheese - and became a target for bullies.
Caitlin With Mum Who Gives Her Full Support
She said: "Childhood was hard for me. I was picked on by kids and came home in floods of tears." At ten, Caitlin weighed a staggering 15 stone as she continued to feast on fast food - sometimes up to three-times a day. But her weight began to get her down and by 13 she embarked on a crash diet. Caitlin - who is recently broke up with her long-term fiancee and primary 'feeder', said: "The bullying got me down so I tried to lose weight.
"I'd go to the gym three times a week and survive on just boiled chicken and crackers. I got down to 11 stone by 14. "But I was miserable. I felt like I am a naturally big person and I felt like I had betrayed myself. "Over the next 18 months I started putting on weight again. As my curves came back I began to feel more womanly and sexy."
At 16, weighing a whopping 21 st, Caitlin had the unconventional idea of becoming a super-size BBW model. She explains: "I came across a website of obese models called Big Cuties and there was this 600lb model who looked like a goddess to me. I knew I wanted to be like them." Shockingly, Caitlin decided to drop out of school at 18, and pursue a career as a webcam girl.
After researching online she registered with an erotic website where women can charge men to view and speak to them. She said: "The first time I performed on webcam I was so nervous. But once I got going it was fun. I wore underwear and exposed my belly. "It boosted my confidence - it was nice to have people lusting over me rather than bullying me."
After several months, Caitlin decided to tell her parents.She recalled: "At first Mum was skeptical about it and a little shocked. She was worried I might get teased by men online but she came round to the idea when she saw how happy it made me." However, Caitlin's dad didn't approve.
"He wasn't happy," said Caitlin. "But I'm hoping he comes round in future." Since starting her webcam work, Caitlin's flabby figure has proved a hit with men and she's has joined one of the top SSBBW sites, 'Gaining Bombshells.' And her mum has been on hand to help.
Caitlin charges up to £7 a month for subscriptions to her webpage and estimates she's made up to £6,500 in total. She says she has hundreds of fans around the world but not all subscribe to her site.
She regularly stuffs her face in front of men and her trademark meal is three meat pizzas, four double cheese-burgers, curly fries, milkshakes and two litres of fizzy drink.
Caitlin says: "Men love watching me jiggle my belly and can't get enough of my cellulite. Other men just like watching me eat and get full. There are some strange requests. Some men want me to eat pure bacon fat or raw meat, which I refuse to do.
"Others ask me to show them my rashes or bed sores, which is a bit disgusting. But I'm not ashamed of what I do. Guys love big beautiful women and I'm proud of my body. "Even the the guy at school that tortured me the most is now one of my bigger fans.
"He bullied me all the time and now he messages me almost daily begging me to get with him and telling me how beautiful I am and buying me gifts." Caitlin has recently broken up with her long-term boyfriend Kenyon is focusing on piling on the pounds and making an even bigger name for herself on the BBW scene.
She said: "I want to be 500lb by the time I"m 30. My long-term goal is to be as big as physically possible without being bed-bound.
"I don't care what anyone says, I love my career and it makes me happy. Having mum's support is the icing on the cake."
