The most talented female deep throater I ever knew was so into sucking cock that, if the guy had sufficient holding power, she could have multiple orgasms during a single blow job. And she would almost always have an orgasm at the end of the job when the spunk starting shooting. Alas, she ultimately married and turned monogamous on me .... but not without leaving many fond memories.
I always thought that she was totally unique, one in a million if not one of a kind. But later in life when I got into sucking dick myself I found that, with the right cock and under the right circumstances, I too could blow a load without ever touching myself ... just from the sheer turn on of sucking cock. Regardless of your gender, orientation or experience, if you're a member of this site you must have adequate phallic fascination to understand the phenomenon. In a number of threads here at LPSG posters have wondered why a person (male or female) can so enjoy giving head to a guy. Well I think this thread pretty well answers that question.
