Himself

Finley understood the greatest way to grow his new silver brood, as he lay on his back and watched his long, swaying cock jut out in front of him like some monolithic steel sculpture, veins bulging and the tip just leaking a few drops of glistening liquid, he slowly curled his thick cock down, circling his cockhead around his puckered asshole before it stretched open for him, his impossible girth easily sliding inside himself, teeth biting against his lips and grinning as he loudly moaned, his asshole gaping and stretching over his own throbbing length, his insides slicked with argent slime.

He just wanted to fuck himself all night long, but understood he needed to do more than that, as he grabbed the wide base of his cock with both hands and pushed deep into himself before letting it slide slightly out again, driving his shiny length in and out deeper and deeper, faster and faster, feeling parasitic cum in his hyper-sized balls churn and gurgle before releasing a hot thick wave within himself over and over, a shuddering orgasm releasing within him. His stomach swelled, bigger and bigger, inflating with his argent cum, giving him a small pregnant belly bump on his small frame. His body looked ridiculous and he loved it, Finley's large basketball sized balls slapping against him, his beautiful swollen monster cock pushed within himself, and a baby bump quickly growing and filling him up, his internal organs replaced with the perfect incubation chamber for a creature of the shine, until even his little nipples started to leak silver milk.

The silver slut grinned, as he let his rod slide slowly out of him and plop to the floor, gurgling cum out like a leaking hydrant. Finley shivered uncontrollably as his large, stretched out belly deflated and a thick glop of silver began pushing itself out of his gaping asshole, his eyes darting around and tongue lolling out of his mouth, feeling the slick perfection slide out and slap to the floor, as he let out a roar of joy.

There it was, beneath him just a pile of silver mass, rapidly taking shape and forming beneath him as he stepped out of the way, shaping into a tall amazonian humanoid form, voluptuous with large leaking tits, thick pillow lips, wide hips, and a leaking hungry cunt of shine.
