Personally I would do mainly the same, no matter what I suck.
Step one, warm up:
Take all the time you need/want, start kissing, biting and more in areas that are close to it or that you know arouse that person (I usually like to explore from outside in), could be a ton of different things, ears, neck, tits, nipples, crotch. Just make sure that person wants more but is still enjoying what you do.
Tantra stimulation can be critical, massage the nuts, behind them, anus stimulation (I like to put a stop when it's a
for me, but the usual would be asking what is okay and what not before, it spoils the fun for me).
Step two, fluids:
The more wet the better, no matter what you're eating, salivate abundantly and/or use oils. I love using the tongue first but you can start with your fingers or both, spit on it or on your hands then keep exploring everything with your senses. The same can be applied to other areas at the same time, fingering from behind while playing with a dick/vagina, nipples as well, overwhelm them with stimulations (breath, fingers, toys), remember to maintain the most possible wet everywhere you play, it helps a lot. If you're using a condom be careful with your hands when playing around, don't stroke it too hard, you might break it or worse.
Step three, mastering the skills:
If you're curious enough you'll discover everything a person wants and what not. Practise will get you to the best levels of oral sex, try new things with the same people you're with and try with other people too to identify differences and similarities to be a true master on all grounds.
Hands can make a true difference if used properly, twist around, stroke harder, softer, find your own technique.
Tits are another skilltree that must not be ignored, no matter the size you can use your chest to put pressure on his dick and waist, lubricate and rub it like a snake climbing his body. You can combine almost every technique with your tits.
Use your tongue to hug the dick, wrap it around and use your hands too, remember to keep stimulating, if you're using the tongue on one side, stimulate with your hands where your tongue is not, start from bottom to top.
If you're gonna use your throat you're gonna learn to move your throat muscles properly, I suggest your practise on your own to see what could fit and what could not. The great thing about using the throat is that you stimulate the tip in a fascinating way, just be careful of the physical limits (lenght and thickness).
Extra careful with your teeth, the harder the dick the more sensitive it is, the mouth should usually be wide open, then just use your tongue as a pillow when entering and once inside your mouth, then you can play with your tongue around and use your lower/superior lips to cover teeth and ensure the dick's comfort.
Step four, enjoy!
Things to consider:
Long hair can be easily controlled but it's even better leaving it free and develop skills to put it aside while you're on it.
Eye contact usually is key, you don't really need them to be great at oral sex, plus the brain gets more stimuli with a penetrating look.
You can use your vagina to suck dicks too, rub it (specially if you're wet) play around and then back with your mouth, you can alternate however you want.
If you're using a condom be careful with your hands when playing around, don't stroke it too hard, you might break it or worse.
Remember the communication, hygiene and protection.
