Then let me tell you one more time
Dutch wife is the predecessor of sex doll
A long time ago the Dutch went out to fight
But there is no woman around

Physical loneliness makes soldiers uncomfortable
So invented this kind of sex partner
Her name is Dutch wife

As time goes
She evolved into the sex doll we know now
