The confident, Shorter goblin.

Yea, maybe you were right in thinking spit isn't enough... ma-maybe taking other fluids from a goblin that contain DNA might be effective... maybe even more effective? Purely for the scientific discovery that could be had. What if this comes in handy later, but you have no spit no ingest? What then?

Your lustful eyes fall to the short goblin. He indulged your kissing, so, maybe if you asked, he would let you suck him off? A guy with a giant cock like that must be an absolute stud, just built to break in a bitch. Speaking of, his giant bitch breaker was positively throbbing, and leaking pre like a faucet. The size was already huge, but the fact that it was hanging off such a short stud like the shorter goblin made it look absolutely gargantuan. Every vein perfectly crafted to push blood into his member. This, nothing to say about the balls that hang below. Absolutely pendulous, easily egg sized nuts dangle loosely in his sack, a layer of sweat hanging off of every square inch of his crotch. The goblin noticed you staring, and grabs a hold of his dick with his hand to wave it at you, grinning a confident grin.

Using your very rudimentary understanding of the goblin language, you ask if you could have a go at the beast between his legs. "S-suck?" you manage to spit out, neck deep in arousal, pointing towards his crotch.

The goblin nods his head with all of the swagger he can muster, and repeats your question framed as a statement, all while pointing to his monumental member. "Suck."
