Such a basic question.... But there can be so many varied answers...

It feels so good when it turns that corner at the end of my mouth and into my throat.
Kinda like stroking the tonsils I don't have ...

....around the tip here and there and to watch/hear him shudder is like sex to my ears, When in one lick I'll go from the tip and do a loop around the balls and back again over and over etc and he goes crazy lol ..... can't give away anymore tricks .

I love it when she takes one hand and squeezes the base of the shaft and rolls her tongue and lips right around the underside of the head.

Also keeping just the head in her lips while stroking with her hand, quickening the pace and twisting the hand and wrist a little in a circular motion as it goes up and down.

But my all time favorite was a BBJ from two girls, both going up and down the sides. When I said I was going to cum, one started to deep throat me, the other grabbed by head by the hair held my head down, kissed me ramming her tounge down my throat, then giving a good solid bite to my tongue just as I came ... I need a cold shower just thinking about it

loving art!

Oh My favorite is definetly by starting with a light t hard up and down stroke just enought o get him a little alive..
then i like to give it a firm squeeze and slap my tongue with it until he feels hard enough to go inside my warm mouth..
ill spit all my juicy saliva on it and lick it up and down while it slides down your hard shaft..
then ill push you as deep as you go and while I leave it lodged in my throat ill tighten my tonsils around your head so you feel how deep it is..
Mind you ..I have NO gag reflex
t Ill let you grab my head and Coach me as fast or slow as you want while i keep stroking my tongue up and down it while your going to town keeping me in chicken head motion :p
constantly Spitting and making it as sloppy as it can possibly get
so wet itll slide down my wrist and forarms..
then ill put a little pressure just under the boys (balls)
while you face F*ck me until your legs are quivering and your moans cant be held in anymore..
when your ready to cum i want you to call out your wildest fantasy words yet!
whatever turns you on  most!!
I will enjoy every last drop of you until it seems your amazing orgasm is to a complete finish...while i every so often give you a peak of your warmness on my tongue..

WOW I just got all wet writing that lol
Time to go to the bedroom with my atf toy

Definitely the teasing/build-up... My ex would lick and suck on my balls like there was no tomorrow... She would do this until I was at full attention... Fantastic! Then she would wrap her hands around the base of my cock and scrotum and alternate between sucking my balls and cock... Porn star like... She would also do this thing where she would hold my cock down against my inner thigh and just lick is from top to bottom... She was tireless and would suck and tease for 30 min's non-stop... To finish she would take me deep... Hands wrapped around my ball sack until I exploded... I never knew where and how she developed such talent and I did not ask... but for a 24 year old... still the best bj artist I have ever been around... She was a med student... I use to refer to her as my little Japanese porn star... Should have married that girl, oh well.

So here's my answer to my own question....

My favorite part is when the gal is working my cock and a little bit of pre-cum leaks out and combines with a nice coating of saliva. That combo makes the head of my cock ultra slick and amplifies every single touch of my cock head. If it's licked just right (at that time) not too hard, not too soft - it's mind blowing. my whole mid section of my body goes into sensory overload and the reaction of the feeling is very strong in my brain. Totally an awesome part of the blow job experience.

On her knees and facing, her tongue finds the sensitive sweet spot on the bottom of my erect penis, just below the head.  My moans of pleasure tell her when she's arrived.  As she begins massaging that spot slowly with her tongue, she reaches up with her index fingertips and very lightly strokes my nipples.  Soon this 3-point massage brings me to a peak of super-charged ecstasy, followed by climax.  That pleasure peak is most reliably achieved if the woman is athletically coordinated!

Piece of cake ... let me show ya
