A woman who says Mother Nature was "generous" by giving her natural 34KK b.o.o.b.s has shared some of the disturbing messages she gets from strangers online.

Despite having back pain and struggling to find clothes that fit, Anastasia Berthier loves her large chest.

She said: “I haven’t done any surgeries on my b.r.e.a.s.t. Mother Nature was pretty generous to me.

“As a teenager I used to be embarrassed of my big b.r.e.a.s.t.s. “At the age of 15 I was already a D cup. But when I grew up, I learned how to accept myself and my body and even benefit from it.

“There aren’t many women in the world who have my natural b.r.e.a.s.t size, a fit body and cute face, so why I should be not happy?

“However, it’s hard to find lingerie for my size. Some stores cater to my b.r.e.a.s.t size, which is often the biggest size they have in stock, but not for all types of lingerie.

“I have to buy clothes in really big sizes then go and customise it with a tailor to fit, because I have a small waist compared to my b.r.e.a.s.t.s.”

“I do have back pain if I stand or sit in the same position for too long, but daily activities are fine and it does not bother me at all to do sports with the right sports bra. And yes, I can sleep on my stomach.”

But her large size does attract a lot of negative attention online, and on occasion it can actually be quite scary for Anastasia, who lives in Moscow, Russia.

She has faced repeated harassment from an online stalker for years, who has also disturbed her friends, family and even photographers she’s worked with in hopes to reach out her.

And one of her followers threatened to slit his wrists open if she didn’t reply back to his messages.

Anastasia said: “One crazy guy was threatening me that he will go to the kitchen and cut his veins if I will not answer.

“And I have crazy stalker who is following me for a few years, annoying my family, friends and photographers with who I work.

“There is a lot of pretty ill people and it's can be dangerous when they obsessed with you.”

Despite that, Anastasia loves her fans and said they constantly inspire her to create new content to share to the world.

She added: “I do have a lot of admirers and I really love my fans, they are such an inspiration for me! They give me a lot of support and ideas!

“My favourite comments are from women. When a woman gives you a compliment it’s always a big pleasure, but it’s very rare. Also, I love when followers appreciate my philosophy or my life advice.”

Anastasia now works as a model, but before that was a graphic designer and content writer for online magazine. She's also a painter and would often be commissioned for her pieces.

But this didn't pay well, and she was often left with no money at all by the end of the month.

She said: "Sometimes I didn’t have enough money to survive until end of the month so I accepted dinner dates just to eat!”
