But when I think about it, technically, a granny could be as young as 36.
I had considered replying "ah, bless you" the other day when I read that, but....
Gypsy wife becomes world's youngest grandmother... at 23
.... yeah, that's better. That's technically how young a granny could be. You're always reading about 30 year old grans in the trashy magazines. My mate's seeing a grandmother who's currently 37 but I can't remember how old the little one is. Daughter's a frightful little tramp, obviously. I wouldn't touch either of them.
Not that age is much of a barrier. Best sex I've had has been with women in their 40s.
