My alpha says i get him off way too quickly in a blowjob. How do I slow it down??
You must be good, brother!
The key is to regulate the pace of the blowjob by focusing on other areas. Come off of his dick periodically and lick/suck his balls. lightly kiss the shaft of his cock (which is markedly less-sensitive than the head area), and make sure you are not using your hands to stroke it too much. If you do these things, I have no doubt he will last a significantly longer time!
