You are a dirty minded and scrupulous gynecologist and run your own fertilization clinic. Lucky for you there are a lot of sexy girls out there with all of their sexual problems and desires that needs help to get impregnated and with other related issues. Of Course you will do EVERYTHING possible to help out these “poor” girls. You will even get payed for your “hard work” and as you make more money you will be able to expand your clinic, and buy more “tools of the trade”. You also may be so successful that you could hire an assistant or more.
I see endless possibilities around this scenario.
