Skilled Mechanic

A female who has graduated with honours after serving a sex academy apprenticeship. She has proven ability to give rousing, memorable and meaningful blowjobs. It applies to any woman whose oral cavity is in coordination with her respiratory technique, tongue and teeth movements such that the testicles and shaft can both be pleasured at the same time without her having to repeatedly extract one's tackle from her mouth in order to breath! Her mouth is generously ample without being cavernous. The true skilled mechanic will be able to demonstrate ball and shaft swallowing at the same time thus living up to her deserved and well earned academic title! Spitting or swallowing is optional depending on how well the connection works out between you!
