Corinna Blake down for her taut labia to be humped properly

The book I am trying to track down contains this plot: An orphan/foster girl. Her hands smoothed down the crease in the hem of the satin pannier, and she smiled. This book deals least successfully with the problem of an astronaut. He starts with a black heroine and a Jewish hero. Dutch official father, her aunt tries to groom Katrien into a proper young lady.
