"I want see Franz be new Initiate Incubus," Kurt said, noticeably dripping a steady stream of juices from his permanently stiff hard length squeezed inside Jake's wet leather thong. "He like have sex with so many college girl, too."
"Oh, he'll never get to have sex with a college girl again," Jake said with a giggle. He licked the drool spilling off his lips, and said, "but he's not even going to mind once he ... oh, you'll see. Let's go and convert Franz, then. He's about to have an excitingly cool change."
Kurt rose upward into the air behind Jake, thrilled with the ability to fly as his sleek black bat wings lifted him almost weightlessly without even having to flap them too often. As they approached the staircase, Kurt saw their family pet lift its head at the top of the stairs, growling, black jowls peeling back from its canine fangs.
"Good Doggie," Jake shouted.
Instantly, Mad King Wagner's short clipped tail began wagging excitedly as the Doberman sat up.
Kurt followed Jake up the stairs past Mad King Wagner, growing aroused by the dog's warm male scent and hardening member, drooling as the pink canine shaft slid out from its canine sheath. Kurt wanted to mount the Doberman and feast on its warm flowing blood. He wasn't even alarmed that he wanted to have sex with a canine. In fact, the idea was almost as exciting to him as having sex with one of his brothers. And his vampire bat bloodlust needed to be sated, and fed soon, because something inside him craved drinking any male's blood while having sex.
"Later," Jake chuckled. "First we'll change Franz. Then you can feed. Oh, goodie. He already senses something outside his door. Here, boy! Here, Mad King Wagner!"
With a thought, Jake materialized the three of them inside Franz's bedroom at the foot of the 19-year-old jock's sleeping bag. Stretched out on the floor, on his back, Franz Wagner had awoken from the sudden erection swelling at his crotch.
Franz had unzipped his sleeping bag and looked down in surprise at the stiff boner rising up from what was now a completely hairless shaved crotch. Where the hell are my pubes, he wondered, horrified from his missing blond bush as three forms materialized inside his bedroom.
"Who the hell are you?" Franz shouted, covering his unexpected hard-on and embarrassing bald crotch. Dressed in matching queer looking leather men outfits, a slightly muscular Asian teen and an odd looking blondish blackish-haired teenager had somehow appeared out of thin air inside his bedroom. And his family's dog, Mad King Wagner, sporting a full-on raging doggie pink boner, sat between them. "How the hell could you get in here? I locked my door and--"
"Shut it, Franz," Jake interrupted the beefy college jock, cackling loudly. Franz's mouth snapped shut. "A Doberman's not suitable all by himself, Franzie-boy. So, why don't you crawl over to that duffel bag and allow Mad King Wagner to share your jock muscles. He's gonna be your best friend forever, Franz, and you'll be his BFF once you and him are sharing a canine and human merged body. That's right, Franz. Lean down over it and offer up that ass and let him mount you, Franz. You'll enjoy that male gay doggie humping sex real soon, being tied just like a real bitch does with only real dogs. Horny male dogs, Mad King Franz. That'll be your name now. I promise he'll slide right in for you."
Franz's resistance lasted about 2 seconds. He couldn't believe he'd crawled over to his large duffel bag packed with his prized weightlifting and football gear, and was offering his ass to their young Doberman puppy like ... like he were some bitch dog in heat! But that's exactly what he did, and Mad King Wagner, ever the horny male canine, bounded over to him with his bright pink doggie boner bouncing and swinging madly between his short pelted tan and black flanks instantly.
And before Franz could even think how to stop him, Mad King Wagner's long sharp black nails were roughly scratching against the sides of Franz's rib cage as the horny Doberman's slick pink canine boner slid right inside him just like that teen had said. Mad King Wagner's canine cock slammed roughly inside, retreated slightly, then slammed back inside him so deeply and forcefully that even the stretchy sheath around the hard canine spike slipped inside him, too.
Within seconds, the moist thick canine sheath was followed by a hot gushing squirt of Mad King Wagner's canine sperm being quickly and forcefully pumped inside. Franz lifted his head from his duffel bag, thinking, "holy shit, what the hell am I even doing letting Mad King Wagner do this to me? I'm not enjoying this! I've never let anyone stick their dick inside me let alone the horny family dog." Then Mad King Wagner began rapidly and violently humping him! Franz's back arched up in hopeless rebellion, his mouth opened with pain, and Franz felt like he should just submit to the Doberman, helplessly.
And Mad King Wagner was clearly enjoying his domination over the bigger male he'd sometimes have to nip at in self-defense whenever the male put that restraining thing around his muzzle. He wasn't kind like the double stinky younger males who usually fed him, or took him to those places he could mount weaker canine males. Sometimes he could even get close enough to one and smell their butts first, or eat those food-scented treats they'd leave for him, often laying around in a tasty smelly dried clump. Mad King Wagner had only encountered a female canine once, and the bitch bit his snout and barked so incessantly at him, her entire body no bigger than his head, shook with such a jittery nervous aggravating twitch he lost all interest to even attempt mounting the bitch. But this male--although not of his four-legged kind--submitted easily.
When Mad King Wagner's canine knots began to swell, preventing his shaft from full entry, he just rammed inside harder and faster. Then he latched his fanged jaws around the bared neck of the big male, pumping his fluid in with quickened canine spurting jets, repositioning his hind legs for even quicker plunges that made his hard stiff canine spike more slick and the tight hole more slippery.
Unknown to anyone except the Incubus Demon Jake, altering muscles formed inside Franz's rectum so he could tie with dogs in his human form just like a canine bitch, and when Mad King Wagner forced all of his large knots fully inside, the new muscles contracted and held the male's canine cock deep inside, tied, as the Doberman's hot sperm again pumped inside in powerful jets.
"They'll be an hour or two like that," Jake said, chuckling. "Franz's gotta absorb all them Doberman fluids to become what he's turning into, course I don't wanna miss the very last part of that change, so how about we go change ...
