Derrick really couldn't peel his eyes away from the naked half man half wolf sitting on the couch there, the wolf was covered in his own seed, breathing heavily. The cock had barely softened enough to even be considered half flaccid. Licking his lips, Derrick walked over to the panting animal of a man. “I think you still have one more in ya.” He said kneeling between the male’s legs. Jessie could only blush in return, seeing Derrick smile. He nodded a bit. “G-go ahead.” His deep red cock throbbed, a drip of pre landed on Derrick’s face. “Whoa down boy!” Derrick said leaning in, his tongue reaching out to meet the slightly pointed tip of that cock. Gasping and holding his chest, Jessie watched as Derrick slowly took that red meat into his maw. Just sharp breaths escaped him as the male between his legs descended down, those soft lips closing around the red veiny cock felt so good. Derrick grinned around that member, saliva dripped over the shaft. God he was so much like an animal, he could even see the swelling at the base of the member, it was like he was growing a knot, then again he likely was. Derrick started to bob over that member, groaning into it, vibrating Jessie’s cock. Slowly Derrick bobbed back and forth, slurping and covering the canine human cock in saliva. Jessie humped lightly, trying to urge Derrick to speed up, his breaths were quick and light. “Oh gods Derrick.” He was already so close, mostly because he was rather sensitive from that last orgasm. He couldn’t help but hump and grab Derrick’s head and pull him down. Those lips slurped over the slightly swollen bit at the base of his smooth dick. “MMPH!” Derrick grunted, yet underneath his pants, his own cock was getting a bit hard and it stuck up causing a tent inside. “RRrrrr suck me hard Derrick.” He growled a bit at Derrick for going so slow. Derrick got the hint and just started to bob faster, sucking hard, slurping louder as his lips spread over that knot, just over and over. Gods it felt so good! Jessie growled and humped, his clawed hands gripping that head, the tips of the claws digging into the scalp, just making for a bit of a pinch, but not breaking the skin. Noticing how animal like Jessie’s voice was getting, it just turned Derrick on even more, his eyes moved back down, every time he pulled off that cock, it looked slightly more red, and that knot seemed more swollen. By now he couldn’t feel the man’s glans on his tongue anymore, and the tip felt rather different every time he tried to deepthroat it. It was like he was changing even while giving the man a blow job. He groaned around it and suckled down any bits of pre that kept dripping from that pointed tip. Jessie was getting closer and closer to his climax, he just looked down, listening to those slurps, his black ears twitched in pleasure, as his soft tongue just hung out of his black lips. “Rrrr come on! Derrick harder!” he shouted as he kept thrusting into that maw, by now Derrick wasn’t really doing any work anymore other than keeping that tongue on Jessie’s cock, and his lips clenched tightly over it as well, keeping it a perfect little hole for Jessie to just get off in. “Nnngg!” Derrick grunted, his jaw having to open a bit wider each thrust, Jessie’s knot was starting to swell out more. He didn’t want to stop though, his own cock was soaking his underwear and jeans in pre. There was a very obvious spot on the tip of the man’s tent. Jessie’s foot moved down and brushed up against Derrick’s member just over the fabric, yet he just ignored that. His legs pulled up as he held Derrick down between them, that mouth over that throbbing cock. Derrick kept bobbing back and forth, Jessie’s knot swelled out even more as he was getting ready to cum. Growling out, leaning his ears back, Jessie humped hard a few hard times before a quick throb, and another howl escaped the changing man. That wolf human hybrid seed started to spray down into Derrick’s maw, coating his throat in the white sticky stuff. Derrick couldn’t make a sound as Jessie made sure Derrick’s nose was buried in that soft pubic hair that was more like fur. Eye’s clenched, Derrick tried to swallow all of that doggy seed, but it was just too much, some spilled out between his lips and that swollen knot. Jessie was panting, almost like a dog, as he came down from that orgasm. Derrick slowly pulled off and wiped his mouth off in his arms. “Good boy!” He said teasing Jessie. “Shut up.” Jessie replied and leaned back, letting out a huff. Derrick couldn't wipe the silly grin off his face. He knew why he loved that so much, he just hated it was happening to his boy friend. He crawled up and sat next to the changing wolf man and leaned in against him. Jessie looked over and smiled at Derrick, “That was good… but…” He yawns and stretches out his arms. “It’s late and I think it’s time to sleep.” He said leaning his head over and he was instantly out. Derrick chuckled and got up and pulled the man over. Hoisting Jessie up, Derrick huffed and started for the bedroom. “You’re so adorable sometimes.” Derrick said with a smile. Each step was a heavy thud with their combined weight. He slowly lowers Jessie down on the bed. The man was completely naked save for that pendant that he was given. He looked over the overly hairy man, just wondering if Jessie would ever give into the change, he was hoping that he’d just go along with it. He’d have a perfect mate, a canine… that could think for itself, with a human mind but with such an attractive body. The chances of him actually giving in were slim. Jessie was fighting it the whole time, save for just now. But that could have just been the lust that animals have, maybe it was just too strong for him to easily resist. Derrick crawled into the bed with him and snugged up against the hairy man. He let out a sigh and played with the chain the pendant hung over his neck. “Good night my sweet.” He said kissing into a furry ear. Sounds of snoring filled the room as Derrick passed out, but Jessie’s snores were irregular and were often interrupted by grunts and dog like moans. As both men slept, Jessie was squirming about, trying to stop the itch that was taking over his lower half. The thick hair that had grown there was growing more. The fibres were soft, slowly the black fuzz grew in volume. The change didn’t wake either men, but Jessie was clearly getting annoyed in his sleep, the sensations were affecting him in his dreams. In his dream he was running around, on all fours, he couldn’t really focus too well, he guessed that he was on paws, not hands and feet. Before long he sat down on his haunches and started to just chew and nip at his legs, trying to stop the itch. Jessie whimpered and squirmed as his fur was growing in, covering his legs completely. He whimpered like a puppy in his sleep as he was getting agitated. It didn’t stop there, as the hours passed with both males snoring away, skin began to bunch up over Jessie’s soft and boned member. Bunching up more and more, it pulled his member up against his groin and belly. Black fuzz took over the skin as it was taking over his red pointed cock. It was oddly tight, causing Jessie to grip and pull at it in his sleep. Not enough to wake him, the sheath continued bunching up and soon took over the tip and created a new home for the penis. Both would be in for a heck of a surprise in the morning. Neither set the alarm clock, and it was bright outside before either woke up. Jessie was the first, he stretched and yawned, using his right arm to prop himself up. He saw Derrick there behind him, arms around his waist covered by the sheets. “Morning.” He said lightly, but not loud enough to actually wake him. Groggly, Jessie crawled out of the bed and wobbled his way out into the bathroom. He scratched just over his side, above the new fur line. As he approached the toilet, he looked down and yelled out. “AH WHAT THE FUCK!?!” Derrick woke and sat up in a snap. Jessie was looking down at the new sheath, and the whole lower half covered in fur. The change had continued through the night! This didn’t happen last time. Why was that? He kept thinking to himself about this. Derrick burst through the door and looked at Jessie with eyes wide. “Oh god, you changed more.” He said slowly walking in now to offer the man a hug for comfort. Jessie didn’t have the slightest idea about what to do now, he had to pee, and this thing, it was in the way. He sighed and returned Derrick’s hug through all the thoughts racing through his mind. “Okay Derrick the shock’s gone, I knew the changes would at least go this far, I just didn’t expect it to happen while I was asleep.” He said. Soon, he pushed Derrick out of the rest room, despite what Derrick wanted. He looked down and frowned, he wasn’t sure what he should do. He looked to the toilet and then back down. His hands moved down to the black fuzzed sheath and pulled down. He groaned a bit as the tight flesh slid down his cock. He moved a thumb down and started to push his cock down, the bone inside wasn’t making it easy or even comfortable as he started to angle it down to the rim. He bit his lower lip and just let the wizz flow. It didn’t flow easily as he was pinching his urethra closed. Finishing up the man let go of his sheath and it instantly took over his member, closing over it tightly. Jessie shivered and looked down at himself.What was different last night over the night before? What caused him to change in his sleep? He kept wondering these things and hardly noticed that the pendant that Derrick gave him was still hanging around his neck. Derrick outside was wondering the same too, but he soon remembered something. He remembered where he got that pendant, some crazy old lady said it would make the next person to wear it his perfect mate. He didn’t really think too much on that part of it. He just figured it would help him out with his problem for liking animals more than just humans. He didn’t think well enough on that phrase either as it was turning this man into his perfect…. mate. He froze as he thought about this, maybe this was why Jessie was turning into a wolf. A wolf that could think and solve problems on his own, an animal with human intelligence… That was something he had been longing for and he tried to be rid of that want because of it’s impossibility. That had to be why Jessie was turning, it just had to be. It seemed all too unreal, but the evidence couldn’t lie. His boyfriend was turning into a wolf. Derrick sat there, his cock getting hard the more he thought about it, but the more he thought about it, the more that he figured he should tell Jessie. That everything was his fault, but he didn’t want to miss out on the chance for something like this. Yet how could he go on living with the fact that he turned his man unwillingly into a wolf. He didn’t know if he should confront Jessie about this or not. He kept weighing the good and the bad over and over in his head. He kept thinking about how hot this was, that he was having lustful urges that were so hard to suppress with a human mind. He could just not tell him, and Jessie really would be none the wiser to it all. Even once he was completely wolf he could just take good care of him. Yeah that would be what he should do. He couldn’t think about what Jessie would do to him if he was told. He didn’t know if he’d lose him as a boyfriend or even as a friend. If he’d be attacked. There were so many scenarios that could just end up bad for him. Not once did the thought of Jessie accepting it, and would continue the change just for him. That was just too much for a man to really do. He heard the shower running and a quick squeak and the water stopped flowing. He must have been thinking the whole time Jessie was in the shower. He figured he’d follow the man in after he was done. Jessie grunted out as he was rubbing the towel through his lower half. The fur clung to the fabric of the towel, being pulled and not much water was getting out with it. He growled at himself and just got his legs and feet to the point that they were just damp. He finishes up his upper half of his body and just walks out. “Hey seemed you were having some trouble.” Derrick said and waved to him. “Don’t worry we’ll figure this out and stop it okay?” He faked. Jessie sighed and nodded. “One can only hope.” Was Jessie’s reply. Derrick walked over and hugged Jesse and felt over his wet tail. He giggled a bit and walked into the bathroom. Jessie’s ears twitched as he heard the water turning on. He figured it wasn’t a good idea to just put on some clothes with his fur being so wet. Then again his sheath actually did a good job hiding what needed hiding. He looked around and sighed. His hands idly played with the pendant around his neck as he waited for Derrick to come out of the shower. He’d ask about that sheath now that the initial shock was gone. He didn’t think it was a bad idea to ask, to at least know about what was going on with is body. Derrick seemed to know what certain parts were. He flopped back and looked down over himself, noticing that some of the fur had crept up from the waistline, it now had a bit of a taper leading up to his navel. His hands slowly moved down to his sheath. He blushed some as he felt over it, the flesh was stretchy, yet the cock inside, still had that erect feeling to it. He stopped before any blood rushed to his cock. He didn’t want Derrick coming out to seeing a hard dog cock and risk him pouncing it again. He sighed and stood up, he started for the door and went for the kitchen. There was something off about his feet, every time he took a step, it felt like he was walking on swollen feet. He didn’t stop to look though. He looked around gathering two pans and plates. He dipped into the fridge, bending over, his tail raised up without him actually telling it to do so. Derrick walked in seeing that sight, he noticed how Jessie’s crack wasn’t very deep. He quickly walked by and slapped that furred ass causing Jessie to yelp and hit his head against the fridge. “Ow hey! Watch it!” Jessie said as Derrick just giggled and sat down at the table. Jessie had gone back down, this time making sure to keep his tail down. He came back up with bacon and eggs. He quickly threw the bacon on and tossed the eggs into a bowl. He went to his pantry and pulled out some grits and threw that into another pot. He was quick to work with the breakfast, the last thing they were waiting on were the grits. Soon Jessie had tossed Derrick his plate and told him to help himself. He made enough for three people just incase Derrick ate more than he did. “So did you come up with anything while you were showering Derrick?” Jessie asked just before biting down on some bacon. He noticed how his teeth just tore through the meat a bit too easy. They must have gotten a bit sharper since the last time he ate. Derrick looked up and shook his head. He had to struggle to keep his cool on this one. Now that he was pretty sure the pendant was the cause of everything going on. Jessie sighed and looked down at himself. He wondered if he’d ever get the nerve to even put on clothes like this. He was sure the fur would itch like mad if he put on pants and underwear. Of course Derrick would cut out the holes needed for the tail, but he’d rather not ruin any of his pants if they could reverse the change at all. He looked at Derrick noticing him eating rather quickly, while Jessie was going at a slow pace. “Derrick what’s wrong?” He asked, noticing something was up. He wasn’t onto him hiding anything though. “Nothing, I’m just hungry is all.” He said quickly, thinking that was a good excuse to use. Jessie shrugged and went back to eating. Derrick had finished before Jessie was half way done, he got up and took his plate to the sink and rinsed it off. “Thanks for that, you’re a better cook than I am.” He said thinking it would be a shame once Jessie’s hands were lost to the forms of paws. He looked over the half fur covered body and blushed. Jessie got up and turned to Derrick and nodded as he finished. They both moved to the den, Jessie got on his laptop while Derrick just turned on the tv and loaded up some video games. Jessie started to look around on the net for anything that could help him with what was going on with his body. “Oh Derrick I meant to ask.. what’s this.” he said moving his laptop off his lap and showing his doggy bits. Derrick turned and blushed some. “Oh that… uh most four legged animals have these, they’re called sheaths. They’re supposed to help aim and keep you clean.” he explained quickly. It was almost disturbing that Derrick was able to answer that so quickly and with that much detail. But when he thought about that one word, aim, his mind couldn’t help but drift to sex. His heart pumped a bit faster, and blood rushed down to his groin. His toes curled up as he felt an erection coming. He tried to not think about it. He quickly pulled one foot up and sort of crossed his legs, but he looked at the bottom of his clawed foot. There were these odd black patches that looked a bit swollen on his feet. One big one just before the toes, just under the ball like joint. He bit his lower lip knowing that these were the pads for his paws that he’d likely have if they couldn’t stop the change soon. He noticed that the pads were missing on his pinky toe. He didn’t know why that was right away. He forgotten that canines had only four toes on their hind paws. This worked for now, his heart stopped beating so hard now, and his cock remained inside of his sheath. He pulled his laptop over his lap again and started to type away through his favorite search engine. He found several things pertaining to transformations, and his luck he found something based on real life changes like this. But nothing seemed to match his situation or even point to any sort of cause for what he was going through. He was reading through several things that could potentially work. Some mentioned some things could be as simple as jewelry, and that got Jessie thinking. He looked down at the pendant that Derrick gave him. It was just a simple jeweled necklace. There was no specific shape about it, and the site described these objects with more detail than this thing had. But he had to wonder if it was that. He didn’t change at night the first time because it wasn’t around his neck when he was out. This time though, he had the necklace on in his sleep. What if this thing was actually the cause of all this. He looked to Derrick, and wondered if he meant for this to happen. So far he really couldn't tell. If anything he knew that Derrick felt bad for him. Especially after he shouted at him and kicked him out of his house. Maybe he just didn’t know the necklace could do that. He sighed and took the pendant off without saying a word, Derrick noticed him doing that. He frowned and wondered if Jessie had worked out what the problem was. Hoping that this would allow his changes to reverse, Jessie looked down at it and then back to the website. He was reading through so many paragraphs of stuff, but nothing lead to any sort of reversal. Permanence was starting to become engraved into his mind as he was hopelessly looking for that one word. He got an idea and pressed ‘find’ in the menu and searched for the words he was looking for. Everytime he typed up one word, he’d get the error sound. He sighed and his ears went low each time that sound went off. “This is hopeless.” he said snapping his laptop closed and tossing it off to the other side of the couch he was sitting on. Derrick frowned and came over to him, putting the video game down. “Don’t say that. Even if you don’t change back… I’ll take good care of you.” he said rubbing over Jessie’s back. Jessie couldn’t help but to smile a bit for that. “Thanks, at least I’d have a good owner if I did become some dog.” He said curling his toes, he jumped a bit as he felt the claws digging into the carpet. He’d have to get used to that if he couldn’t find anything. Derrick had started to rub down lower, going for Jessie’s tail. Oddly enough it started to wag between the couch. Derrick grinned and leaned into Jessie. “Honestly, I think you’d make a good wolf.” Jessie looked down at Derrick wide eyed. “Yeah maybe, I just don’t want to be one.” Derrick nodded and just hug to him closely, cuddling up to the half fluffy man. His free hand moved down to Jessie’s furred groin, rubbing over that sheath. Jessie couldn’t help but to blush a bit as Derrick was getting intimate with him again. It didn’t matter all that much by now anyways. At least the change would be stopping if it really was that pendant. He curled his toes as his cock began to swell, a pointed red tip emerged from the black tip of the sheath. “Mmpph Derrick… you’d be the better dog, you’re the one that seems to be so turned on by this.” Derrick giggled in response. “Maybe so, too bad I’m not the one changing eh?” Jessie relaxed as he let Derrick have his bit of fun, the other man was rubbing and pulling down on that sheath to expose more of that cock. He bit his lower lip and his ears leaned back against his head. His tongue hung out the side of his black lips, his eyes slowly closed. Derrick’s hand slid over that red rocket of a dog cock. While Jessie’s eyes were closed Derrick carefully picked up the necklace and slipped it back around the other’s neck. Jessie was so focused on what Derrick was doing between his legs, he didn’t even notice. It helped that it was rather light as well. Derrick grinned as his hand moved back down to that dog dick. It throbbed and leaked a bit of pre as he was getting horny. Jessie clenched his toes and growled a bit in pleasure, his tongue sticking out to lick at the black wet spot of his nose. His cock swelled out, and was just dripping pre right off the pointed tip as Derrick pulled it down and tugged on it. Jessie opened his eyes and looked down to the other male. “Rrrgg you’re making me horny again Derrick.” He said leaning over and pulling the man’s hands away. Derrick’s heart sank as he felt like Jessie was just going to stop him from having a bit of fun. Surprisingly Jessie pushed him over on the floor, turning him to his hands and knees. “This time you’re going to get filled.” He growled out. and pulled down on Derrick’s pants. His red meaty cock throbbed and swayed in the air. He bent over and gripped the man’s chest as his cock hung just behind the man’s ass. His thick fluffy tail was flagged up in the air, his tailhole exposed. Jessie’s head hung just behind his neck, huffs could be felt on Derrick’s hairs. Derrick couldn’t stop blushing, his own cock was hard, and it hung down between his legs. He looked back and nodded, though Jessie wasn’t really looking for his confirmation. Jessie poked his pointed tip to the male’s pucker and pushed in. His voice was deeper as he growled and pushed into the man’s ass. Grunting, Derrick clenched his eyes and fists as he felt his ass spreading open for that tapered shaft. This was so hot, he thought. His cock throbbed and dripped pre right on the carpet. Derrick huffed and Jessie growled out, nipping into the man’s shoulder as he started to thrust into the man’s ass. Moaning, Derrick backed into the thrusts, thanking god that the canine cock was already slick with pre. Jessie kept his teeth on his shoulder, his ears were back as his thrusts started to get a bit fast, so much so that Derrick couldn’t keep up. All the while Jessie as going wild with the man’s ass, fur began to creep up his torso and back. It was spreading out because he was giving into his animal side. The fur kept creeping up without the man noticing. The hair was already thick so it was hard for him to feel it as he kept sliding in and out of Derrick’s hole. The sounds of flesh slapping against fur. Jessie’s hips met with that ass over and over. Derrick’s cock flopped and he clenched his ass as tight as he could now that he was adjusted to the size of that member. “Oh gods Jessie! Keep going!” He begged while he was on all fours. The wolfish man just huffed and kept going, keeping those pointed fangs on his shoulder, not letting go but not breaking the skin. The thrusts got faster, and the slapping sounds grew louder. Jessie’s growls grew louder as the fur was creeping up his chest. This as the fastest any change was coming on. His knot was swelling up as he was getting closer and closer to filling Derrick with his seed. Derrick couldn’t stop moaning, keeping his hole clenched tightly, until he felt the knot bumping against his pucker. He bit his lip and looked back, trying to relax as he wanted to be tied for the first time. The two males were getting frantic the more they got into it. Jessie’s eyes clenched shut as he felt a dull ache over his face. He couldn’t tell but his nose and jaw was starting to stretch forward. It was very slow and almost unnoticeable. The fur was still rushing up over his chest, those teeth held tightly as his knot swelled out even more. He humped harder and pushed for a bit trying to sink that knot into the man. Derrick noticed and tried to push back with each one, feeling his ass stretching out a little more with every thrust. Jessie whined a little bit, his voice sounding a bit more like a canine’s. Jessie’s tongue lapped against the skin of Derrick’s shoulder while those teeth were still holding fast over his shoulder. It wasn’t too long before that knot popped in. Jessie yelped, and Derrick grunted, and followed up with a moan. “Oh gods! So full!” he squirmed under the wolfish man. His hole clenched down just behind that knot, his ass flush with the other’s hips. Jessie’s thrusts grew faster, more frantic, and shallow, the knot tugged on Derrick’s rear rather hard with each pull back. He was almost sliding on the ground with the power of Jessie’s thrusts. Jessie only growled more, his voice getting deeper as fur was just part of the way up his chest. He was almost completely covered in the midnight black fur. “C-come on boy! Cum in me!” Derrick begged, absentmindedly talking to him as if he were a dog. Derrick’s head hung low as Jessie finally let go of his shoulder. His lips pursed up and he began to howl out, his canine cock throbbed inside of that ass and started to spray his thick sticky wolf cum inside of the other male. Derrick blushed as he heard the wolf howl over his head, feeling that seed just spray and coat his inner walls. Jessie’s tail was wagging furiously behind them as Derrick’s ass clamped down, he was cumming as well. His human shaped cock just throbbed a few times and then let loose the comparatively smaller load between his knees. Both were panting and breathing heavily as they came down from their highs. “Oh gods Jessie, that was amazing.” He said. Jessie’s ear perked to that and he grinned. That grin soon faded as his face throbbed in pain. He growled and let go of Derrick’s chest, his hands landing on the ground. His skull was pushing forward, forcing his skin to stretch for it. His nose was turning up and becoming flush with his lips. He groaned in pain from it all. Fur was spreading down his arms and creeping up his neck as the change was kicking into overdrive. Derrick looked back and grew concerned. “Jessie? What is it? What’s wrong?” Derrick could see that his face was starting to push out. Oh god! He thought, Jessie really was going to become a wolf. The pain spread down to his hands. His fists clenched up, his eyes did as well as he tried to bare down with the pain. Jessie tried to pull out of Derrick’s ass, but the knot held fast and kept the two males together. Jessie whimpered and whined, his hands came up to hold his head, as his skull pushed out more and more, though it was hardly millimeters at a time. His fingers curled up on his face, but the joints felt stiff. Suddenly there was a very loud boney pop, then another. Jessie’s head was looking forward now, naturally, but to him it was like looking up. He put his hands down on Derrick’s back, he tried to stand himself up but his hips cried out in pain. They didn’t want to go back to that stature. “AHHG!” He fell over and threw his hands back down on the ground. Derrick couldn’t help but to feel bad, he felt like he did this to Jessie. In a sense he did. He was the one who threw that pendant back around his neck. Derrick looked down at his hands, he could see fur starting to spread down around the fingers, the fingers were growing fatter and were getting a bit stumpy. Jessie cried out in pain once more as his thumbs were pulling back, shrinking faster than the fingers were. “Ahh h-help me Derrick.” Jessie begged, but both were helpless really to do anything. Jessie kept trying to pull out of the man’s ass, Derrick grunted and told Jessie to stop. “Y-your knot’s to big!” He said. The man was almost wolf, just a few things were off, the muzzle wasn’t long enough, and the shape of the legs were right, same for the arms. The pain had passed just as quickly as it came, Jessie’s thumbs were gone, the fingers were shorter but they still had some dexterity to them. There was the beginnings of pads on the fingers. Jessie was laying on top of Derrick whimpering a bit. Derrick reached a hand back and rubbed the man’s side in comfort. After having gone through all of that, Jessie’s knot shrank enough, so Derrick pushed it out and helped Jessie up. “Oh god, I didn’t think it would go like this.” Derrick said. Jessie was scared now, thinking about how fast everything went just then. He tried to stand up a few times but his body just wasn’t made for it anymore. Derrick helped him up on the couch by holding his paw like hands. Jessie still managed to sit like a human. For now they rested, while fears festered in Jessie’s mind. He didn’t even want to look at himself, he knew it would be even more wolf like than before.
