No sex should be without a blow job. And in general, it is on oral sex that relationships should be built. After all, if the woman will suck, the man will always be happy. And if the man will be happy, he will make his whore happy. I think you understand the logical chain. The truth is, a blowjob is not a blowjob. All guys prefer a deep blow job. Only in this case, the technical characteristics of the sucking mouth should be appropriate. At least the throat should be deep. By the way, what is the throat of your chick, deep or not? Or your dick in her mouth only half a lump goes in?
