Fourteen year old girls smuggling grapefruits in bikinis

A buddy of mine’s 13 or fourteen year old SIL, has got a nice, wide set of birthing hips. I pity the doc who has to handle it when she gives birth. That kid’s gonna shoot out of her like a shot from a gun!
When I first met her, I pegged her age as being roughly 16 or 17. She carried herself like a teenager and certainly acted like one. From her build, etc., etc., I concluded that she was on the verge of being legal (and yes, certain thoughts did race through my head). Then I find out that she’s twelve! (And, yes, I did feel horribly dirty about my earlier thoughts.) Twelve years old and she already stood almost 5’10", in the years since I met her, she’s grown to be my height, has grapefruit sized breasts, and if she hold’s still, you’d think that she was eighteen or better. She also has a tremendous crush on me, so I do all I can to avoid contact with her.
