The flanker is matter of fact as she tells the beginning of her rugby journey, "I was 27 before I started playing."
She continues: "I used to play Gaelic football. At the time I was playing county football for Kerry for three years. It was quite ironic as I was giving up as I had had enough of all the travelling.
"There was another girl who had given up at the same time as me and she was going to join the local rugby club."
That was in 2007 and just over five years later Fleming was part of Ireland's women's Grand Slam winning side of 2013.
When asked if she ever thought that she would find herself as an international rugby player, she laughs heartily: "Not at all! I am still thinking 'how did I get here?'"
Fleming's original motivations for playing were rather more modest than being capped for her province Munster and country, she adds: "I was purely doing it for the fun and for the exercise. I wanted to try it because I always loved to watch it on the telly."
The Kerry woman's first foray onto the rugby field for her club Tralee RFC was not the most auspicious start.
"the first game I played in was just a challenge match against the local college," said Fleming. "It was very unofficial and was probably not the best day to have my debut playing rugby."
Laughing as she explains, "I came off the pitch and I was saying to the girls, 'this is just crazy, this is the most crazy sport I have ever played, I don't know if I can do this!'"
However, her second match was to become a turning point, "then the next game which, was a proper game, where we would have had proper reffing and things like that, I don't know what happened but I came off that pitch just buzzing."
She adds: "It was just this feeling inside, it was the greatest thrill. I was just addicted then, it was just like something clicked in me and there was no coming back."
Growing up in the village of Currow, County Kerry in the southwest of Ireland Gaelic Football was a "massive" part of Fleming's life. However, the area also has an exceptional rugby pedigree.
"We have had major rugby stars in Currow where I am from, between Mick Galwey and Moss Keane, the Doyle brothers and now JJ Hanrahan. It is remarkable for a small little village," she said.
The forward gives an insight into her mind set, when she says, "I never would have played rugby to see if I was as good as those guys. What they did is amazing but it was never my journey to see if I could be like them."
Fleming is honest about her own awareness of the women's game before she became involved and how it has grown in the public consciousness, "when you think of where women's rugby has come from, it is not that long since I started out," she adds. "I will be the first to put my hand up and say I never knew there was a Munster women's team not to mention an international women's team.
"And now, if you were to go out on any street in any town in Ireland and ask about women's rugby, I would say there would be very few who would not know about it."
As a result of this heightened public interest in women's rugby and last season's Grand Slam success for Ireland, Fleming and her teammates have the opportunity to play in Dublin's Aviva Stadium for the first time this coming weekend against Italy.
Women's rugby coming to Lansdowne Road, is in Fleming's words, "an acknowledgement of the sport and it is an acknowledgement of the work and the commitment and the sacrifices that we make."
She describes her commitments to rugby that include training and gym sessions in the evenings and Ireland camps every weekend in the build up to the Six Nations as, "a full time job outside of work itself."
It is with great enthusiasm that Fleming talks about her day job as a special needs assistant, "I love my job! I am in a mainstream school," she said. "I am assigned to a little girl in first class. I would also help the rest of the class. I think every class should have someone other than the teacher, as there are always kids who need that extra bit of help.
"For me the difference between the teacher and the special needs assistant is that you can really get down and be a big kid with them as well. We have great old craic and banter as well."
Part of the thrill of this weekend's fixture is that it will be televised and this gives the children Fleming works with a chance to see her play, if selected, "the class are massive rugby fans," she says. "We don't really appreciate the value of being on telly until you come home. After the England match every one of them was like, 'we saw you on the telly and you were number six!'"
"It makes them see where I am gone off when I go training, that I am not just missing! It is lovely for them to be able to make the link to me playing through the television."
Perhaps, some of her young pupils will be inspired by this to take to the rugby pitch and follow Fleming's journey in wearing the green jersey.
