Go at it from behind

You swallow your pride and move behind the dragon, to get at his cock and balls from behind.

"What is your name?" he asks as he moves his tail, exposing his asshole and balls. "I wish to know what to moan if you do a good enough job."

You tell him as you sit on your knees, your face disgustingly close to his red asshole. "John? Well, John, I am Cambin the Red. Begin when you are ready."

His semi-erect dick lays flops on the ground. You reach your hand out, and are shocked as it is extremely warm. Not to hot to touch, just...unnatural. You put both hands around his huge dick, and your fingertips barely touch.

You begin moving your hand up and down his red penis, avoiding the spikier parts toward the base. You try and imagine how you would want a handjob in order to replicate that, but you keep getting distracted by how rough his member is. The overwhelming musk coming off of the sex-starved beast doesn't help either.

Apparently what you're doing is working however, as his member begins to grow, getting ever more difficult to get a grip on. The dragon musk grows stronger at the same pace. Cambin groans in pleasure. "Yes...just like that, John. Trace your hands on the tip."

Leaving one hand pumping on the shaft, you change position so the other can move down and delicately stroke his hot tip. At least here you escape some of that overpowering musky smell.

You continue like this for a few minutes, alternating between stroking his tip and using both hands to stroke his member, until Cambin speaks again. "Your tongue! I've heard the human tongue works wonders; please, use it! Kiss my balls, lick my penis, I don't care what you do, just do it!"
