My mother bought me a wife

I'm the quiet shy type and a nerd is what I was called at university, my mother widowed wants grandchildren and as her only child it's up to me to produce said grandchildren. But at 26 and no girlfriend my mother purchased me a wife 20-year-old okay on the eye and shy like me. But we get on very well together and my wife is pregnant and due in early November, and I can't thank my mother enough. Lucky we're very well off financially.
