A Traditional Family

My wife to be grew up in the country, She told me about a family tradition.
The night before the wedding the mother was to bath her child for the last time.
She explained her mother had been so insistent with traditions growing up,
she wanted to know what I thought about it.
I said "aww that's nice, your mum is losing her daughter and this is her way of remembering your innocence". You should honour the family tradition.
She then asked if my mum was alive would I do it?
What could I say? I had already said she should do it, "Yep, no worries".
She said "good, because your mum has passed, Mum is insisting she doing you to".
"your straight after me". I nodded of course babe, nervously.
I went thru with it. At first I was terrified, she lifted my arms, washed my back and chest.
I started to relax, I had put way too much thought into this.
Then she took hold of my manhood, as I jumped she laughed, relax your got nothing I haven't seen before. Those words are meant to be disarming. all I could think was please don't get hard please don't get ... dam you! She was smiling good that makes it easier to wash. Easier to wash? didn't she understand that if she kept doing that it .. nooo don't think about that!
With a grin she said, That's normal, don't worry about the mess, it means you will have plenty of children. I gave up and let her have her way. She seemed to be glowing, "you will be the perfect son in-law'.
