The Naturalist [M/Femboy] [fantasy]

It was a humid summer morning as the Naturalist trekked down towards the valley’s floor in search of a fae. It was perhaps late in the season for such an encounter, but it was to be his last day in the region, and he felt lucky – and the Naturalist had learned long ago not to ignore such premonitions. The air was heavy of the richness of gardenia, and birdsong echoed from one of the numerous trees.
Resting his travel pack against the trunk of the willow, the Naturalist settled himself between the roots and freed his swelling shaft from his trousers. His fist closed around his member, slowly stroking himself to hardness. The Naturalist was thick, with dark, curling hair nestled around two heavy balls. His eyes flickered shut, relaxing into the sensation of rising pleasure.
Within moments, the Naturalist felt a cool breeze against his face. He sensed their presence before he opened his eyes, the familiar electricity that hung in the air wherever a fae was present.
“Hello, there,” the Naturalist said, and opened his eyes.
A few feet away, the fae blinked long eyelashes at him, curiosity plain across his youthful features. He was slender, blonde hair messily trussed into two braids, each interwoven with flora, although the rest of his body was quite hairless. His minimal coverings were made of woven summer grasses, a quiver of arrows hanging at the back of his thighs. Rising from between his shoulder blades were a pair of glimmering wings, catching the sunlight that shone through the willow’s hanging greenery. Like a church’s window, the limbs casting jewel-tone blues, reds, and yellow hues over the ground. Between his legs, there was a slender and uncut cock. As the Naturalist’s eyes roved over the creature, he assessed that the fae was certainly an adult, fully-grown to the size of a young human man, although certainly within his first century.
As always, the Naturalist’s breath caught in his throat at the remarkable sight. His hands twitched for his sketchbook to capture the fae’s extraordinary likeness, but he knew refraining from sudden movement was critical in the first few moments.
The Naturalist continued to stroke himself as the creature’s gaze wandered over his body. The corner of a pink tongue dragged across the fae’s full lips, and the Naturalist’s lips twitched in a smile as the young man’s member rose in arousal. He had been measured, and found agreeable.
On silent feet, the fae approached, watching the Naturalist in wary caution, until he straddled him at the waist. Their eyes held, and the Naturalist was delighted to see the shimmering colours of the fae’s wings echoed in his eyes.
“Easy there,” he rumbled.
The fae lowered himself onto the Naturalist, who grunted as he felt the head of his cock bump against the fae’s opening.
His entrance was slick, a feature of fae anatomy in which the Naturalist found utterly superior to human males. He bit back a moan as the fae lowered himself – the heat and tightness of the fae’s innards as equisiate as he remembered from previous encounters. And yet each was incomparable, like different vintages of perfectly aged wine.
The fae placed a slender hand against the Naturalist’s shoulder, bracing himself as he began to pump up and down. His pink mouth opened, a whimper escaping. The Naturalist, moving slowly, rested his gloved hands against the creature’s thighs, even though he was eager to thrust his pelvis upward and take what his body demanded. It was always best to let the wild creature lead.
Even so, there was nothing to complain about, and the Naturalist’s eyes rolled in their sockets, pleasure rushing through him.
In due time, blue, luminescent cum began to leak from the fae’s cockhead, evidence of his own arousal. With a wordless cry from the fae, it spilt across the Naturalist’s tunic in thick, glowing droplets.
“Good boy,” the Naturalist gasped. The praise earned him a tired, honest smile that reminded him that although languages may be a barrier, fae had been theorized to sense the emotions of a human. The Naturalist could only guess that was the reason the fae began again in eagerness, watching him closely with his bright eyes. His head dropped against the roots of the willow tree, the heat swallowing him.
“I’m – I’m going to…” The Naturalist struggled to form coherent words as the liquid heat built to a point in his gut.
Dark spots burst before the Naturalist’s eyes as he came, his pulse thundering in his ears as his cock twitched inside the creature. Without thought, he seized the fae’s cock, sliding his palm across the slick shape – and with a whimpering cry, the fae came again. More cum splattered across the Naturalist’s gloves and jerkin as the creature’s pale thighs quivered. He collapsed against the Naturalist’s chest, glimmering wings fluttering behind him with each shuddering breath.
After he had awoken, the Naturalist had carefully collected samples of the fluid in his jars, knowing the high price it would fetch in the nearby town – although he would keep at least one for his private collection. Although the fae had long since vanished, he was certain he could feel bright eyes watching him as he shouldered his pack and began the long trek out of the valley.
