Seize his cock

Her iron grip fastened itself around Bowens cock, cutting off all fluid transfer, even blood circulation. A look of painful realization crossed his face before his eyes rolled up into his head and he let out a choked scream of pleasure. Thanks to the luminous quality of the magic-imbued cum, Lilith was able to actually watch as his oversized balls convulsed and the majority of the glow left them, traveling deeper into his body before re-emerging at the base of his cock... Where her grip stopped it cold.

Bowens cry of pleasure instantly morphed into an anguished call of pain as the duct bulged with surging cum, his cock turning a greenish-purple from lack of blood-flow. He stumbled backward, falling on his side as he tried to no avail to escape her vicelike grip. With nowhere to go but back into his body the cum pushed one last time against her hand before the pressure released back into his bladder. Lilith smirked as his engorged balls began to visibly shrink and he let out a high moan. Her magic began to do its work as the cum was reabsorbed into the treemans body, the green glow shining through his abdomen and spreading outwards.

The effects were obvious almost immediately: Bowens muscles softened, their chiseled quality reforming into something smoother but no less appealing, just like the formerly strong lines of his face, which bent and expanded into more smooth contours. His broad shoulders shrunk, the weight redistributing to his hips even as his smoothing stomach cinched up tighter, and his chest developed a very unmanly puffiness.

Lilith was so enthralled by her work that she didn't realize she was losing her grip on his diminishing cock till a spurt of nutty cum struck her face, momentarily blinding one eye, "Oh you little bitch!" Cleaning her face off with her tongue and trying not to let the delicious taste impair her rage, Lilith seized the tip of the once again spasming meat stick (which had shrunk to about half its original size) and halted the escape of the magical cum. Bowen groaned as the momentary release was halted and let out a high pitched keening as the demonette sadistically wrung the cum filling his cock back into his body, "That's right, you aren't allowed any release till you take the full load." Lilith flicked his overtaxed balls, rekindling some of their glow with her magic and drawing a panicked yelp from the still-morphing treeman.

Mindful of her grip, Lilith continued to watch as the glow spread to Bowens fingertips. Like most of his body their girth shrunk to more effeminate proportions and his nails grew out slightly, emphasizing their dainty quality. Similarly, his wild tangle of mossy hair grew out and straightened, falling in a silky green curtain around his contorted face. The corrupter maintained her grip on the shrinking sex organ till she was holding nothing but a tiny nub which, with a final weak pulse, shrunk back into the treemans body. Lilith kept her finger on it just in case. His balls were likewise minuscule, having emptied their entire volume into his body. With an unpleasant slurping sound they retracted into his body, leaving a cute little slit behind.

As the glow faded Bowen was left a heaving, sweaty mess. The taught leafy skin was now harlequin green, like new shoots in the spring, and had a supple quality that clearly separated it from its plantlike origins. Lilith pulled her finger away to reveal a similarly cute clit, engorged with arousal, and a tiny urethra. A small dribble of the former treemans male spunk leaked out, which Lilith deftly swept up with her tongue. She was rewarded with a faint shiver from the exhausted fey, who appeared to have passed out from the strain. "A treewoman... No. Treegirl is so much more descriptive. I am going to have so much fun tasting that nutty-" Too late, Lilith realized the flaw in her plan, "Damn it!" Without balls it would be impossible to milk the treegirl of the delicious cum she'd just sampled. Come to think of it maybe she shouldn't have consumed magically imbued transformative cum...

"Oh well, I'm sure it's fine. What to do with my new toy... maybe I could make her produce actual milk for me. Shouldn't be too hard." Lilith pondered for a moment, still unsatisfied, "But what if it tastes different? What if instead I sent her to go collect other treemen's cum... now there's an idea!" Either choice was sadistic, one just involved turning the treegirl into everyones bitch instead of just her own. She absentmindedly licked the last bit of glowing cum from her lip as she considered her options, the still gasping Bowen laid out before her...
