There is a possibility she wasn't grey hair grandma old, if "step sister" is a baby, everyone on that side had kids young and aunt is the youngest.... But it does sound disturbing how its written.

The op said the grandma's aunt. So if I'm correct that would great-great Aunt. I'm assuming she's in the 60-100yo range.

Well not in all cases...sometimes the aunt/uncle is younger than the niece/nephew...it's weird but not uncommon

GILF? Grandma I'd like to fuck?

GILT - Grandma I'd like to tongue?

Who doesn't love a good gumjob every once in a while?

I have a nephew that is three years older than me.

Classic

@33 - Touche. My friend has an aunt the same age as her.

This step-stisters grandma's aunt could be about 40 years old just about, It's possible the OP could just have an older best friend... although this is a bit of a stretch :/

or his step sister's young.

Colin?^ Or there could be an age gap between the friends

Hold up a second. If you calculate this. Lets assume OP's best friends is 16. If grandma was born when mother was 20, and great granny was born when mum was 20, granny's aunt could be as much as 40 years younger. (see next comment for rest)

Lets assume 25 years younger. Lets say stepsister is also 16 and her mum and and her were born when their parents were twenty, so granny is now 56, aunt could be 31. Or if you were to take an extreme and assume early and late sexual activities, birth at mothers only 12 and late as 50 then aunt could be unborn. So best friend could also be a paedophile. But I'm sure it's not as bad as it sounds anyway.

I was guessing OP could be early twenties, with a step sister younger than ten. Atleast then it makes his sisters great aunt not look like a pedo.

That is one of the weirdest FMLs I've read... -___-

Basically, the OP's best friend hooked up with someone three generations before him.

Thank you for the explenation. Points to you for not being a smart ass.

Haha, no problem.

Well aunts and uncles can be much younger than their nephew/nieces.

I'm guessing 60-70 years

It was most likely divisible by 30.

Well if the age difference is 20+ years then the higher probability is that the younger man/woman is after her/his money...not "love"! Be real

that is a really good picture! its like she posed for it

53 - to your pic: stalkers.

It could have been a she. That would be a better story.

Lol, I get it... 'great' grandma, and 'amazing' aunt...

And so is 911

A number and potentially a statutory rape charge.

12- The only people who say that are the people who are dating someone who is too young/old and trying to make that sound ok.

And a jail cell is just a room

Are you the friend he is talking about?
