Subtly take your mouth off his dick and lick this balls while you continue to stroke the shaft, or gently caress his balls with your fingers while you suck him. Be forewarned that he may be so turned on by it that he'll cum right away. Be sure to tell him upfront that you're okay with him cumming in your mouth or wherever so he's not worried about where to cum. Also try licking the perineum. Ask him if he likes what you're doing. When he cums, keep doing what you're doing until he stops ejaculating. If that's in your mouth, keep his dick in your mouth for a minute until he desensitizes. Then pull gently on the shaft to squeeze out the last drops of cum.
Both. Licking the balls, stick them in your mouth. Move your tongue on and around his cock and balls. Make some nice moves with you tongue. Be creative with your tongue.

When in doubt, lick and suck.

Lick yes you can do that. Suck is a resounding no that hurts!
In a standing BJ, gently cup, lift and knead them as a unit. When the guy cums, you may feel them lift on their own.
touch them and guage his reaction. if its a pistive reaction then go further and repeat till you learn what he does and doesn't like
Yes you can lick them and gently suck on them. If he is shy and doesn't express much you can break him out of this by looking him in the eyes as you suck on him as you moan out sweet purrs, also smiling as you lick his shaft and all around being enthused.
