"Ooh, we're getting feisty!" Karyn growled as she sprang toward him, crashing into her mate. She growled seductively atop him as he landed on his broadening back.
"Don't you know it, bitch," he snarled. Her scent was driving him insane; both his nose and cock began shifting in response.
Karyn licked her lips. "If it were anyone but you, I'd tear their throat out."
"And since it's me?"
"It sounds so perfect. Right now, at least."
Steadily, she began grinding her hips against Jon's crotch, dampening their underwear with their mutual love. The few strands of pubic fur snaked through the meager coverings twisted and flowed further outward, pushing through and from underneath as their fur began spreading over all their skin.
Jon, especially, snarled in sweet agony at the thickening of his penis, growing sheathed and triangular into a proper wolf's organ. He dug grooves into the carpet with curving nails as his testicles swelled within their furry sack.
Karyn could smell his eagerness, knew what her mate needed. Quickly but passionately, she gripped his straining briefs with both clawed hands and tore them away. Jon growled in sheer delight as she deftly began stroking him in her developing paw. Precum clung to his pelt of rich black fur.
Karyn looked to him, deep in the throes of change. She understood this heat well; she could remember how it felt, long before she found this wonderful man to be her mate.
Her own changes were accelerating, but she wanted to bring Jon home first. She slid perpendicular to him, and gripped his furry sack gingerly in one paw before sliding her mouth over the tip of his cock.
The effect was like acids and bases. Jon howled from the slow strokes of her mouth and tongue, and surrendered himself to his transformation. As she sucked him, he felt every muscle explode and rebuild itself, coupled with thicker bones and a black-furred hide.
Saliva dripped from his eyeteeth, flowing freely from a jaw that was slowly becoming lupine. He growled in delight, and reached a thick paw to his mate to claw through her bra. Already, he could feel her six nipples through the growing pelt of fur, the counterpart to his own triumvirate of stiff buds.
His mate continued to go down on his wolfhood, sliding his meat carefully between her fangs, and he braced himself sideways to make room for the growing tail nub to blossom. It billowed and furred, coupling the reshaping of his legs and dewclaw.
Climax was imminent, as was the eventual reach of his furry ears to the crest of his skull. He felt his face push into a muzzle, and snarled at the slight pain and incredible sensation. Karyn sucked him faster, feeling the displacement of her panties by her own swelling tail.
One final deep throat pushed him over the edge. The completed werewolf raised his muzzle and howled as his semen pumped deep into Karyn's throat. The hungry she-wolf swallowed every drop before tossing her own head back in a lustful growl.
She leveled her golden eyes at her alpha, nearly bowing on all fours before him. "Make me cum!"
