Muahahaha. This is my fave thing to do (I don't rim much though, too much of a surprise bag down there lol)
I watched a video on how to give a pro blow job thinking it would enhanced mine, only to realize - I do a crap tonne of stuff that wasn't in the video. So, I'll just list those;
Start with the balls, suck on them, lick them, slowly move up the shaft to the head, tongue the urethra - trickle the head with your tongue, and kick it up a notch, instead of continuing the slowed pattern, throat it. It's not expected d=. Put your top lip over your top teeth, tongue over your bottom teeth and bite down whilst sucking, try to stick to the head to halfway down the shaft with a couple of deep throats thrown in from time to time. If you need air, disguise it by tonguing the urethra, or licking the head and going back down to the balls. While doing this lightly apply pressure to the 'taint' (the spot between the balls and ass), massage the balls. If your jaw gets tired/sore, you can relax it a bit by putting your tongue over your bottom teeth, and your index finger between the cock and your top teeth ; suck/or not and jack it like that - gets a few good moans out lol. Now to conclude with my signature trick that alot of people don't do: when deep throating swallow - it takes a couple of times to get used to, but it starts to feel really nice after a few times - and even better for them. Sadly I may do this a bit too much and haven't had any one last over 6 minutes >_>. So I try to stick to regulars that I know can do multiple loads, cause I could suck cock for hours if anyone could last that long lol.
