This is the complete Mail Order Bride series.
In volume one, Mail Order Virgin, Henry can only get turned on by virgins. The problem? He is in his 40s and hasn't had a virgin since his teen years. Then he finds a mail order bride company specializing in this, and is about to have all his fantasies come true when Mai arrives, a 19-year-old half-Thai, half-Chinese girl. Will she be the answer for Henry?
In volume two, Mai's Turn, Henry continues Mai's submission training, only to have her turn the tables on him once she discovers her financial rights and the power she holds over him. Much to his surprise, he enjoys giving up the power to her, and finds contentment by being cuckolded by his half-Thai, half-Chinese wife. His sweet, innocent mail order bride transforms herself into a powerful, sexy woman who knows how to have her cake and eat it, too.
In volume three, Polyamory, the adventurous married couple continue the natural progression of the evolution of their sexuality by foraying into polyamory: their final frontier.
Warning: For very mature listeners only. Contains extreme subject matter, to include adult themes of submission training, orgasm restriction, anal, dominance, cuckolding, etc.
