"Ooh, special sauna today? What's so special about it?" The curious rabbit wrapped a towel around his waist and pushed open the door. "O-Oh!"

He blushed as he saw a big red dragon, lounging with his legs spread and a tree-trunk thick dick swinging between them. Steam vapour seemed to be rising from his body, filling the whole room with a volcanic heat. 

"S-Sorry!" The rabbit turned, his white paws over his eyes. "I-I didn't mean to look!"

"Hey, no need to be shy." The soft growl came from behind him. "There's nothing to be shy about. You can come in."

"B-But if you're using the sauna..."

"What? Oh, not quite." The dragon's grin was audible in his voice. "I am the sauna! All this steam? It comes form the sweat vaporising off of my post-workout body. Feels good, doesn't it?"

"Y-Yeah..." The rabbit had to admit that it did. The wet heat was blowing across his back, and even just like that he could feel it soothing the stress out of his muscles. 

"Then come in! Trust me, you'll feel great." The dragon's claw, hot but not scalding, touched the rabbit on the shoulder. 

The rabbit blushed, but he was a little too shy to leave at this point. He let the door swing shut behind him, sat down and let his towel slip. He flushed from the heat and the exposure, trying to settle. 

"Hm, want it a little hotter?" The dragon suggested. The rabbit nodded, and the dragon grunted. The room rose a couple of degrees as the dragon's scales glowed slightly red. 

The rabbit leaned back, fully relaxing and letting his legs spread. He was sweating, the stink of it mixing with the scent of the dragon, lending a curiously invigorating aroma to the room that made his heart race. The heat wasn't just coming from without, it was blazing within.

In fact...

He opened his eyes, and squeaked as he realised that his little dick was standing proudly to attention. He looked over and realised that the dragon's dick was projecting out strongly too, at least a foot of pure solid meat sticking up into the air. 

His mouth gaped open at the sight. It was glowing with heat, just like the rest of the dragon's body. Pure lust and sexual musk seemed to radiate from it, filling the rabbit's lungs with every breath. 

"Helps with the blood flow, doesn't it~?" The dragon nodded happily, giving his length a stroke. 

The rabbit just moaned, staring in awe at the shaft. He took another shaky breath of the musky air, feeling his own erection throb with need. 

"You know, some dragons, my kind of dragons, were worshipped as fertility gods back in the day." The dragon spoke conversationally. "We had the power to broadcast the kind of 'feel good' vibes through our sweat, and body heat generally."

The dragon stood up, his body blazing with pheromones, and strode up to the rabbit. He unashamedly stroked himself over the quivering lapin. The rabbit's eyes were fixed on that shaft, growing hazy and they lost focus on everything else, all their attention focused on the wonderful smells. 

"It's not always that strong, but in a small room with not much air flow, the effect can be quite warming, and [i]potent[/i]~" The dragon put a foot on the bench and leaned his hips forward, letting his balls swing towards the rabbit's face. 

The rabbit took a long sniff.

Then he leaned back, moaned and let out a hands-free orgasm that shot his spunk all across the floor, splashing against the opposite wall.

"Whoa, not much in size, but there's that bunny virility!" The dragon grinned. Another sniff sent a gush of hot cum spraying up across the rabbit's legs. "Don't worry, we've got plenty of time here."

The dragon gently turned the lock on the sauna door, before turning back to the panting bunny.

"Let me give you a real workout~"
