David moaned loudly as Saul tossed the box aside & laid his chest against David's back. Growling loudly Saul wrapped his arms around David's abdomen, the fur felt warm & soft against his back. David groaned as Saul's canine knot pushed past locking the two together, Saul leaned over to David's ear & said " Do you like that my horny little fox boy? Do you want me to fuck you like an animal?" He whispered. David removed his mouth from Tim's tool & replied "Yessss! Fill me with your hot foxy seed." " David, don't stop!" Tim wailed. David immediately brought his mouth back to Tim's prick. Saul & David moved there hips together slow at first then faster, David's eyes rolled back in his head sliding his warm wet tongue along Tim's canine knot & tip. The trio fucked for hours, their tongues rolling out of their mouth's. " David, it's starting. Your becoming one of us." Saul informed him. " I can feel your tail forming, tickling my balls, I can see your back becoming hairy." He added. " Nice fur coat you're growing there, and what big ears you have, so sexy & pointy...oh shit…aaahhh…uhh…yes…yesss…yessss…ahh." Saul moaned, their furry balls rubbing against each other. " David, your fur, it's...it's gray. Your becoming a silver fox, holy shit!" Tim shouted. David eyed the full view mirror behind Tim, body now covered from head to toe in a handsome pelt of thick silver fur. His thick tail merged with a great looking ass.
This drove Saul over the edge, in his excitement he lustfully leaned over & bit down on David's furry mane. He felt a surge of animal lust and his cock grew another inch in length. David growled & lifted his ass out of instinct, Saul took full advantage pushing his cock even deeper. David's body was gaining mass in his chest & arms, his feet reformed themselves. His big toe shrinking in to his foot, arches disappearing, ankles stretching away from his four remaining toes. David shifted his feet, feeling that he was standing on his toes & not his whole foot anymore. Light brown soft leathery pads graced the balls of his feet & hands, toes changing length. Feet becoming more akin to a dogs then a humans, but definitely larger. Long gorgeous ebony claws outstretched, transformation near completion. A warm furry flap of flesh closing around his now very uncircumcised fox cock, seconds later reemerging from it's new sheath. David's reddish pink shaft swelling at it's base forming his new knot. With a loud crack David's muzzle stretched outward in to a beautiful vulpine shape. "Ohhh God...God...suc...oh...oh suck harder fox boy!" Tim moaned. David quickly obeyed, " Yes, oh dear God yes, I'm going to...going to...to...CUM!" He screamed.
Almost instantaneously both Saul & Tim shot there load, Jet after jet of warm fox spunk filled David's muzzle & ass to overflowing, he greedily swallowed as much as he could. The air filled with the blissful howls of the three foxes, cum flew everywhere, on everything & everyone. The overwhelming pleasure was finally to much for David to bear, " Hey Tim! Open wide." David snickered, grabbing his long shaft blowing his hot fox load in Tim's face. The foxes collapsed in exhaustion laughing loudly basking in the joy of the moment, several minutes later David freed himself from Saul's knot. A loud sucking sound was followed by a pop, he stood up, a half gallon of cum gushing from his furry ass. David's foxhood still fully erect lay gingerly in his right paw dripping with his newly released fox spunk. " Your beautiful! Wow, look at that wonderful sheath, your cock & balls are so nicely shaped." Tim beamed. He leaned down & buried his wet nose & nuzzled his sheath, breatheing in deeply tacking in it's musky sent.
" Such a nice smell." Tim said licking David's furry sack gently. The two foxes backed away as david moved towards the full length mirror to get a better view of himself. He cocked his head to the side, dick in one paw balls in the other. His forearms & paws were gloved in a luscious black fur, his calves down to his feet also socked in jet black fur. Ears & tail tipped in black, creamy white fur stretching form his chin to his groin & inner thighs. David's left paw moved along his inner thighs, the fur much thicker then the rest of his coat. " Thank you!" David sighed. " " Thank you so fucking much, all of you! " " So, what now? " He said, a naughty smile across his new muzzle.
