Dominating Aunts

All of the novelettes in this book describe how aunts (and their daughters) psychologically change their nephews into nieces - or at least sweet young things who appear to be nieces.
"Aunt Rose's Place" tells of a young man who is only too eager to enter the service of his girlfriend's aunt. He succeeds beyond his wildest dreams.
In "Aunt Morag and her Daughters" a young man unintenionally offends his aunt who is caring for his mother. She punishes him as she would her own daughters - and he develops an effeminate streak.
In "Fanny" a young orphan is taken in by a family of women. He is quickly reduced to a simpering equivalent of one of the daughters in the household.
