18th birthday 1st time story

[YDB95]

I think I read it in 2012 or so...a woman survived an especially brutal rape that resulted in a pregnancy, and when her daughter grew up, the mother wanted to be sure her first time was pleasant rather than the nightmare she'd been through, so she enlisted a male friend to make love to her as an 18th birthday present. I seem to recall the mother wanted the guy for herself, but she had problems with relationships because of what had happened to her.

I suspect the story has been removed, as I've already looked high and low for it, but I'd love to be wrong...
