The proud mum swapped a career as a suburban piano teacher for the glitz of glamour modelling, with her initial operations funded by strangers online.
Allegra, 47, styles herself on what she calls the “extreme Jessica Rabbit look” and openly talks about her “boob greed” and her desire to go even bigger.
Allegra grew up in a traditional Mormon household in Salt Lake City, Utah, and was a musical prodigy, performing as a professionally trained pianist at a very young age.
Speaking of her Mormon upbringing, she said: “I still believe in the core values of the church, their family values, but I couldn’t live with some of the principles.”
She settled into a tranquil life as a mother and piano teacher, but in her 30s she decided to pose for some modelling shots - and quickly got hooked.
But while Allegra loved being the focus of attention, she felt self-conscious about the effect of motherhood on her 34C breasts.
“After you breastfeed children your breasts are not as cute as they once were,” she said.
“Being someone who cared about the aesthetic, I wanted them to be fuller and rounder and even have a little bit more."
Allegra, a UK size 10, lives in Newport Beach, California, decided to go under the knife, enhancing each breast by 800ccs to a 34DD.
Emboldened by her surgically enhanced chest, she began putting images for sale online - which helped pay for her second boob job a decade later.
She now earns up to $100,000 a year posing for sexy pictures, with her 34MM cups in high demand.
She said: “After my first enhancement, I didn’t feel like it was enough for me, because bigger is better in my mind.
“I've actually got 'boob greed’ - I see something that I love, that is clearly bigger than I am, and I think, ‘Oh, I am greedy for that.’ You know I just want it.
“The word ‘greed' does have a kind of negative connotation but I did this for myself and the more that I did, the more that I wanted to do.
"I had women come out of the woodwork that I knew who said ‘I love the way you carry them. I would love to have bigger boobs but I worried about being slut shamed' or 'I am worried about what my family will think’.
“I want to be the 21st century poster woman for carrying big breasts and making them be classy and still not just be pigeonholed as maybe in the porn industry or as a stripper."
Allegra’s second boob job took her to 2000cc and the feedback she received was so positive that it gave her the idea to go into glamour modelling full time - despite the odd twinge of guilt due to her Mormon past.
Her third augmentation was paid for by a benefactor that she met through the My Free Implants website.
Tissue expanders were installed which enable her to inflate her breasts via a port by injecting them with saline.
Allegra’s breasts can now reach a colossal 4,000ccs in one breast and 3,600cc in the other - and weigh as much as 20lbs.
She said: “They are usually used for breast cancer survivors and they put it under the muscle and expand the tissue after a woman has a mastectomy.
"The expander for me is used obviously for a different purpose. It is a 2000cc bag put under the muscle, which is accessed with a syringe.
“I do 60ccs at a time but I have done as much as 340 or 320 CCs on each side and I do that every two to four weeks but I have been at the size now for a couple of months."
"I am nearly 50, and I'm still growing my breasts!” she said.
In total Allegra estimates she has spent around $75,000 on surgery.
As well as her three breast augmentations, she has had a Brazilian butt lift, a tummy tuck, upper and lower silicon lip enhancements, Botox and fillers.
The 5’7” beauty makes close to six figures featuring in modelling shoots and selling shots of herself online.
And Allegra credits her breast inspirations as country singer Dolly Parton and actress and model Pamela Anderson.
Amusingly, Allegra has no idea what cup size she is - the last bra size she remembers was 38HHH, but “that was more than 2,000ccs ago.”
“Also, one of the big reasons why I got a boob job is so I wouldn’t have to wear a bra because I just don’t like them!” she added.
Nevertheless she acknowledges that having such gigantic breasts can make some daily tasks more challenging than normal - including doing up her own shoes or just walking through a doorway.
She said: “Doing my own shoes is difficult, especially on this side, my boob is a bit lower due to a tear I had in January when I got a little overzealous with the fill.
“Getting through doorways or narrow spaces can be tough too. If I am not poking out in the front, I am poking out the back.
“But if the worse I can say is that having such big breasts has created a few hindrances in my life, I can definitely live with that.”
Allegra’s giant cleavage also gets in the way of her practising her beloved piano, as she has to reach over them to play.
But while she is closing in on her 50th birthday, Allegra says she does not worry about how her breasts will look as she ages.
She said: "I am kind of older now and I like what they look like.
“The beauty of having expanders is that as easy as it came in, it can come out the same way. So I am not too concerned.
“I’m 48 in May and if I am looking like this at 48 I am not really worried about the future.
"I can just picture I will be taking care of my great-grandkids and they will be like, ‘Grandma what big bowling balls you have!’"
During the recovery from the last surgery Allegra heard a bit of a pop due to over inflating them, but despite warnings from doctors, she plans to continue to 6,000ccs - all while still doing the school run.
And Allegra is now on a mission to prove that having giant breasts doesn’t make you a bimbo.
She said: "I am really enjoying the size I am at right now, but I definitely can see myself wanting to go bigger.
“I love the challenge of seeing how big I could go and still maintain some measure of class and sophistication.
"I am really traditional at heart, but I really just have this one aspect of my life that’s incredibly extreme and so I think there’s a lot other women out there who feel the same way I do.
“They are too afraid to may be have that extreme aesthetic. They feel like they have to choose one side or the other, like they can’t be a good mom, homemaker or businesswoman and have the sexy look. I will change that.
"I believe you can and I would love more women to embrace it and feel comfortable and if I can help them do that, I’ll be happy.”
