Bend him double

Lilith leapt up and shoved the boy against the wall of the hollow in a sitting position, he was in no shape to resist. With a wicked cackle she grabbed him by his head and bent him double so that he was faced with his pulsating erection just as his first load erupted from his cock. The blast of greenish ejaculate caught him square in his open mouth and he sputtered, trying to throw off her weight on his back. She had to use all her strength to hold him down, bracing her shoulder on his neck and raking her claws down his back, trailing paralyzing magic. The effect was slow but his resistance lessened and she was able to push him an inch or two lower, till his bursting erection was pressed right up against his face.

He was still erupting vigorously all over himself though he did his best to angle his gasping mouth away from the fountain of magical spooge. Even though the vast majority of the corrupting ejaculate hadn't made it inside, she could see the copious coat he was receiving was beginning to have an effect. His skin was beginning to take on the glow and she wasn't having to fight as hard to subdue his muscles. Still, this wasn't enough, "Mouth open." Lilith reached around and seized his jaw, "Drink. It. DOWN." She shoved him down onto his own erection, laughing sadistically as he coughed and choked, cum leaking out his nose.

Bowen had lost all sense of what was happening to him. As soon as his orgasm began he was lost to pleasure... or he would have been if this insane fairy hadn't contorted his body over itself. All fey were fairly flexible... unless they were of the earth. Or trees. Like treemen. This was the singular most painful pose he'd ever been in, he could actually feel the fibers of his back snapping. That was the main problem, to say nothing of the eruption of glowing liquid from his penis. He was vaguely aware of what was happening, he'd seen enough animals pair up beneath his tree to know this was part of the mating process, but he was pretty damn sure it wasn't supposed to go back inside him. Then the insane fey somehow got even stronger and slammed his mouth down on his erection, his lips slipping a good third down its impressive length. The cum splattered over his eyes seemed to be clearing and he was treated to the horrifying sight of his engorged testicles, glowing with the same unnatural feverish green as his ejaculate. He only had a split second to worry about that though as they convulsed again and sent a monster load of liquid directly into his throat. Still not having recovered his breath from the exertion, he took a good bit of it down the throat while the rest bulged out his cheeks. No matter how he struggled he couldn't seem to escape the corrupted fairies hold, if anything she just kept getting stronger. Choking on the copious amounts of hot green goo leaking from his mouth and nose, Bowen started gulping it down to make room to breath.

"Good... good boy. Swallow all that cum down." Lilith ground herself against the treemans back, stimulating herself even as she dominated the weakened fey. She could feel the strength leaving his body, both as her magic did its work and from oxygen deprivation. She leaned into it a bit further, gripping the boys head in her clawed hand, and forced him down till she heard him gag. What a pity. He was only halfway down his shaft. She felt a vindictive thrill as she did to him what he wanted to do to her, "What's the matter? I thought you wanted to force your cock into a nice warm throat? Take it FURTHER!" She shoved him down and held him as his magically enhanced orgasm continued to pulse into his throat.

She watched with delight as his mossy hair lengthened, turning into long curls that fell in a mop around his head, wetting itself on the overflow that covered his legs. She could feel his bone structure shifting, or whatever substitute treemen had, from his masculine lines into feminine curves. Her gyrations against his back became much more pleasant as his taught skin softened with plush padding, turning an even brighter shade of green under the effects of the magical glow.

Bowen was seeing stars. He'd never wanted to explore how much his plant heritage supplanted his need for lungs but he was getting the answer now: not much. His lungs burned but he couldn't get a breath in with the majority of his own erection down his throat. At least now he wasn't drowning in his own ejaculate and he could sort of... nope. Still suffocating. It was a horrifying realization that the last shove had pressed his lips all the way to the base, his own balls were contracting directly before his eyes, emptying eruption after eru-p... Oh. That was different. Maybe it was the lack of drowning but he was starting to notice the (what had she called it? Kum?) was burning like berry beer in his stomach. He wasn't so sure now if his vision was swimming from lack of oxygen or from whatever was in the stuff coming out of his penis. Swallowing was getting easier and he didn't seem to be seeing as many spots. Maybe he had plateaued or something and his plant nature was keeping him from passing out. He didn't really care too much it was more of a detached realization, just like how much easier it was getting to hold this pose. His lips were now flush with his skin, his cock had completely vanished inside his mouth. His balls were still at least double their normal size but they seemed to be shrinking and the glow was gone at least.

"Well well, look at you. Taking it like such a good little cocksucker. Why don't I give you a little more of that, Hm? So you can actually enjoy it now?" The fallen fairy reached around and cupped his balls once more, sparking a twinge of panic in the otherwise apathetic Bowen. She let out a long groan, like it took a lot of energy, but red sparks leapt from her fingers onto his engorged ballsack. The sparks rekindled the green glow inside his testicles, as well as enlarging them back to triple size, but more importantly they hurt just as bad as electricity. He screamed around his (cock did she call it?), a pitiful choked sound even to his own ears, but the vibrations alerted him to something interesting.

In spite of all the pain and suffering he was currently experiencing, this actually felt amazing on his cock. The mind numbing pleasure of his balls contracting returned to the forefront of his thoughts, the vibrations of his scream intensifying the feeling. He began moaning, pushing what little air he could through his vocal chords to stimulate his cock. He liked that word. Cock. Lilith laughed tiredly, "J-just (gasp) just like tha-" she slumped on top of him, breathing heavily, only her weight keeping him contorted. He could surely push her off... and he absolutely would. Just after he did this for a bit longer. Just... a while... longer...

Lilith was at her limit. She'd just thrown around A LOT of magic and since she was no longer fueled by nature she had to replenish it on her own. In short: she was exhausted. She barely had the strength to watch the feminized treeslut debase himself. It was really more of a "herself" now. She was really looking forward to playing with this one. Right after she got some... rest...

Lilith slid off Bowen's back but he barely noticed other than to engage his core muscles to keep his cock fully sheathed in his throat. He just kept swallowing and swallowing mouthful after mouthful of magically generated kum. He really liked the taste of kum he realized, liked how it felt churning in his stomach, liked how it burned oozing on his skin, and he really liked how it shot out of his cock with such pleasure. He actually really loved the stuff. The dots were starting to take over his vision again and for a brief moment everything went black.Then he was on his back, sucking in air for what felt like the first time in hours. His cock had softened but still spasmed weakly, leaking hot kum over his belly to pool in his bellybutton. Speaking of which, he had never felt this full before in his life. He felt nauseous as the burning fluid sloshed around in his stomach. After a moment he managed to raise his head, sure he would see his belly distended above him.

It was slightly engorged, not nearly as much as it felt, but that wasn't what caught Bowen's attention. He had breasts. They weren't particularly large, nothing compared to Lilith's, but they were a fair bit larger than Aster's. Sluggishly sitting up, Bowen became aware of all the other changes his body had undergone, "Mother Nature... I'm tiny!" He had no muscles at all! Nothing visible anyway... Turning, he gawked at his heart shaped butt, "What the-oop!" His hand flew to his mouth, his voice was about two octaves too high and sounded cute even to his own ears. He'd gone from a baritone to a soprano, muscly to curvy, hard to plush, manly to... girly.
