I always have the girl start giving the blow job when I am sober.. Then after i get my dick up and getting the blow job.. I load a bowl or light a blunt and put soem snoop dog on and start getting high while getting the BJ. Its fucking awesome to bust a load while ur high = HEAVEN. Anyways I am always sober b4 i get a blow job because I sometimes find it hard to get it up if I am really high then when i get it up then i start smoking.. lol but i reccomend doing this because u get to see what it feals like sober and high dont forget the snoop dog or some trance music lol
