Ethan approached the front door to Tai's house, his stance a bit odd as he walked in, more than familiar with his young bull boyfriend and his family to have to knock first. It didn't take long for the lupine youth to track Tai down, and he ushered the bovine to his room where Ethan clearly had something to say.

	“Ethan, is everything alright, you look nervous?” Tai asked, seeing Ethan was tense. The wolf's only reply was to sit up and undo his pants, letting them drop to the floor for Tai to see a radical change to Ethan's genitals; the sight of a sheath was in place of where Ethan's normally humanoid length hung, allowing the wolf's already weighty balls to appear more prominent than ever. Tai could only stare in wild fascination, shaking his head and wiping his mouth as he caught himself beginning to drool.

	“How?” Was all he could think of to ask as Ethan briefly explained what he'd done to make this change occur.

	“I'd heard of this 'potion' or whatever that can make your junk look any way you wanted, so I saved up enough to buy one and thought I'd go with a little more 'on the wild side' so to speak... I did it for you, y'know...” Ethan replied, giving an awkward chuckle at just how corny his explanation sounded, but any apprehension he felt vanished at Tai's next question.

	“Mind if I try it out, after all if you did it for me...” Tai stopped short as he abruptly recalled something, then speaking in almost a whisper.

	“Kari really likes this sort of thing, so if you want me to have some fun with you first we have to keep it a secret for now... okay?<3” Tai said as he knelt at Ethan's groin, the wolf nodding hastily in agreement as Tai reached out to cup his boyfriend's package, giving their soft round shape a gentle squeeze before placing his muzzle at the sheath. Trailing his tongue around the fuzzy hole in an attempt to draw Ethan's newly shaped cock out, Tai thankfully didn't have to wait long as Ethan's body reacted near instantly. In moments the sight of a more canine looking member, knot and all throbbed in it's complete length before Tai's face, also retaining it's usual fiery orange color.

	“Still just as warm as I remember, too...” Tai said sweetly as he placed a soft kiss to one side of Ethan's shaft, citing a gasp of delighted approval from the wolf youth. From there Tai ran the flat of his tongue under the entire length of Ethan's cock, from root to tip where an already thick dollop of precum sat waiting to be sucked away. As Tai's lips enveloped the slightly pointed head, the flavor of his boyfriend popped in his mouth, prompting Tai to bob his head and draw Ethan's thick length in a bit more with each forward motion.

	“Oh... sh-shit Tai, babe... that...!<3” Ethan squealed, not noticing his voice was getting a bit loud, but Tai didn't seem to notice or care either as he pulled off just long enough to push Ethan sitting back on the bed, spreading the wolf's legs before picking back up where he left off. Unable to stand going at the slow pace Tai was taking, Ethan gripped the small horns on his bovine lover's head and began to pump him up and down his shaft hard and fast, his hips moving up into the motion a bit as well as he got a feel for just how good his newly formed genitals felt. He soon found himself bringing Tai's lips down further and further, but unable to push his whole length in for a reason he didn't quite understand at first. It was only when Tai helped finally work into his mouth what Ethan couldn't that it added up; the knot had swollen at the base of Ethan's member, making it a bit more difficult than he was used to to get it all inside of Tai's muzzle. As it managed to push in however Ethan lost it, throwing his head back in a wild howl of pleasure as he erupted balls deep in Tai's face, sending spurt after spurt of his seed down the young bovine's throat. Ethan's fluffy tail swished madly behind him, signaling all the more the sheer bliss coursing through him, but as his eyes finally opened post orgasm and he brought his gaze back forward, he saw Kari standing at the door after having obviously heard the howl.

	“Hey you two, having fun?” Kari grinned as she closed the door, apparently not aware of the change with Ethan's length still down Tai's throat and thus out of sight. As Tai pulled off however Kari stopped, her whole body language suggesting a double take of sorts while she stared carefully then keenly at Ethan's new change.

	“Hey bro, I know he's your boyfriend and all but... well...” Kari began as Ethan happily gestured her over.

	“You want'im to share, I won't say no to that if he doesn't?” Ethan said, looking back down at Tai to get his approval on the idea, and Tai nodded as Ethan pulled the bull up onto his lap.

	“Hey, you know I have eyes only for you Tai, but no need to hog all the fun to yourself right?<3” Ethan reassured Tai with a kiss to the bovine's nose, giving his rump a loving squeeze and playful smack before looking over Tai's shoulder at Kari.

	“So, Tai told me you like this kinda stuff, mind showing me how true that is?” Ethan teased in a friendly manner, and Kari promptly removed her clothes before she made her way over to join them on the bed. The whole time she couldn't take her eyes off of Ethan's length, rock hard and throbbing as it sat nestled snugly between her brother's buttocks, and sensing what she was after Ethan sat Tai up and then next to him on the bed. With his canine cock now fully exposed for Kari to enjoy, she drank in the sight of it up close and personal as she knelt before him. She'd only been with Ethan a few times before but she never forgot the lupine youth's above average body heat, just enough to feel comfortable as she felt upon grasping the thick orange member in one hand, then both. Despite being older than both of them at 18, Ethan was considerably shorter than Tai by almost a foot, but they'd all adopted a friendly joke of a 'size difference they all appreciated' in the form of just how well endowed Ethan was.

	When fully erect the tip of his length could easily reach his chest if Ethan were to curl forward slightly, and as for thickness it had already wielded quite a lot of girth,  but with the addition of his knot it made the base swell even thicker. It's whole appearance could be best described in one word, beefy. Ethan's balls were also something to behold as much as hold, being over a double handful combined and padding out nicely in Kari's grasp as she stroked and squeezed them inquisitively.

	“No wonder my brother likes you, you always treat him nice and then you have this for some fun between you... speaking of which how about letting me be in between you boys, what do you say?” Kari asked, and both Ethan and Tai's eyes lit up at the obvious offer of spitroasting Kari right then and there, the question was who would get what end?

	“Y'know, I wouldn't mind cutting loose on your cute ass Kari, I always did like those freckles.<3” Ethan said in utter blunt honesty, only getting more eager at Kari's next words.

	“Well then I hope you're up for proving that, you remember how I like it don't you Ethan?” Kari said, referring to her favorite kink of spankings, good firm ones at that during sex, and given her durability Ethan was all too familiar with he knew he needn't hold back with her. With that she let Ethan up as she moved in front of her brother, her excitement building as Ethan mounted her from behind.

	“I guess that means I get a front row seat to that show, let's see how big we can get her, Ethan.<3” Tai giggled at the thought of just how much Kari was able to handle, having taken on just about anyone on the farm and come out not too much the worse for wear, proof she was definitely her mother's daughter. Just the sight and even feel of Ethan's change had apparently been enough to get Kari good and wet, leaving that much less reason for Ethan to go slow as he rocked his hips forward the instant he was lined up with her sex, hilting every last bit of himself knot and all inside of her. Kari's reaction was a loud warbled wail of pure pleasure, only further confirming what Tai had told the lupine youth earlier.

	“Ethan, push your knot in and out a lot, she loves that.<3” Tai said with a devious grin, and Ethan nodded as he took to doing just that, thankful when Kari's volume was stifled by Tai managing to finally work his length into her mouth. As Ethan rocked forward, Kari was pushed face first down onto Tai's length, getting pulled back as Ethan did the same making for a good if not rather slow rhythm. Soon though Ethan's actions were anything but as he picked up the pace, ramming himself hard, fast and deep into Kari's pussy. In the meantime Tai had managed to sit up and grip his sister's larger pair of horns, using them as leverage to let Kari deepthroat him, and as though finally recalling it Ethan raised a hand to give Kari's supple tush a good hard smack. The sound resonated sharply through the otherwise silent room, but Kari jumped in more delight at the feeling than surprise of the abrupt noise, only getting more into it with each subsequent slap.

	Ethan didn't hold back, and the warmer than average sensation of his palm only gave that much more stimulation to the sharp pops he gave to Kari's backside. And with the way Tai held her locked firmly in his own grip to ram his cock nice and deep into her muzzle, Kari was about to lose it herself. She vaguely heard Ethan say something through the haze of amorosity she felt, that and the noise of the pops to her rear, but the only thing she gathered was Ethan asking about something to do with her rump. The flurry of thoughts of what he was wanting was the final straw as Kari came hard, followed swiftly by Ethan and then Tai as both boys sent their respective floods into her, giving her flat tummy a nice little paunch of their combined loads. She could feel Ethan's, nice and warm along with her brother's, a bit cooler by comparison but there was a lot of it, and it was so thick too...

	As both boys finally pulled free Kari was rewarded with a few rogue spurts of Tai's cum landing on her cheek and part of her face, while Ethan got a few warm streaks of white across her lower back and buttocks, ending the first round between them at last. 

	“I don't know if she heard you Ethan, she had that look in her eyes...” Tai said aloud, reminding Kari she'd heard Ethan speak up just prior.

	“I'd asked if she wouldn't mind if I showed my appreciation of her ass for real this time, I just hope I'm not too much for her to take now.<3” Ethan remarked, gloating a bit as even he noticed his newly shaped cock seemed a bit more muscly than before. Kari merely shook her head and smiled as she looked back over her shoulder at Ethan.

	“Like Tai and I both keep saying, you don't have to hold back with me, I wouldn't mind if you double-teamed me either truth be told.” Kari teased, hoping they'd both do just that. That one suggestion was all the encouragement Tai and Ethan needed, and the former was quick to lift his sister up in his arms, hilting himself in her sex while holding her up by cupping her butt in his hands. From that position Tai managed to lift and pull aside Kari's tail, leaving her open for Ethan to dive right into his indulgence. Ethan didn't wait at seeing this golden opportunity, going up to grip Kari's pert breasts from behind as he teasingly prodded the tip of his shaft under the base of her tail. After a soft kiss to her shoulder Ethan nuzzled his cheek to Kari's before pushing himself in slowly, savoring how Tai's sister felt every inch of the way. It wasn't until he got to the knot that Ethan finally did what Kari's mind was screaming for; in a rough thrust forward, he sunk the knot into her tight rear at last, making the cowgirl's eyes fly open in surprise and gasp at the feeling.

	“S-So deep... so gooood...!<3” Kari moaned dazedly as she felt the wolf youth bumping at her navel from inside her, and as both boys began to pump in and out of her words were no longer possible at all. It didn't take long for the two lovers to get their timing right, pumping in and out of Kari in a reciprocation fashion with reckless abandon. Ethan was loving just how soft and supple Kari's buttocks were, slamming into them in something of a 'spanking' in it's own right, while Tai was enjoying the warm, wet walls of Kari's sex cinching down snugly all around him, attempting to 'milk' him dry. Nestled in between both boys and held secure in their combined grasp, Kari was on the edge of heaven, so naturally when she felt Tai lean forward and give one of her nipples a firm suckling the bovine lost it. A loud wail escaped her lips as her head flew back, not holding back a thing in her expression of just how good she felt during her climax, of which was only prolonged as she felt both Tai and Ethan ram into her one final time and unload, flooding her with their own unique loads; Tai with his seemingly endless amount, and Ethan with his wonderfully warm amount.

	“Whoo, damn Kari, Tai wasn't kidding when he said you could go on forever...” Ethan said just audibly winded already, his lack of pacing himself having formed a light sheen of sweat on his muscular body.

	“You're not getting tired already?” Tai asked with a giggle, enjoying the sight of his boyfriend' appearance as he pulled out of Kari to catch his breath for a moment.

	“Just a little eager is all, can you blame me, you me and your sis all going at it at once is enough to make anyone lose control.<3” Ethan chuckled as Tai seemed to get an idea, whispering in Kari's ear as she went wide eyed before nodding with a sly grin.

	“Well we are twins to an extent, and since you both got a turn with me, what do say to us having one with you Ethan?” Kari suggested, clearly more to her offer than she was letting on given that grin that had yet to fade. Undaunted, Ethan grinned back with his own confident smile.

	“What is it you had in mind?” He asked boldly as Kari finally stood up, then ushered him to lean over the edge of the bed wherein she and Tai knelt behind and to either side of the lupine youth. It didn't become clear what the bovine siblings had planned until Ethan felt them both licking at one of his balls each, suckling and moaning to give as much sensation as possible. Ethan's length had started to go flaccid in between the wait to now, but it was rock hard once more in seconds, made all the moreso as he felt Tai and Kari reach around with a hand each to start stroking the bright orange member. Kari focused more on fondling and massaging the knot while Tai had happily taken the stroking the remaining length, their combined ministrations driving Ethan crazy. With how close he was, Tai could see Ethan's toned buttocks flexing and twitching in response to the sheer bliss he was giving his wolfy boyfriend, the sight only spurring Tai's actions on further; raising a hand up, Tai gently brushed Ethan's tail to one side before trailing his fingertip lightly around the edge of Ethan's tailhole, getting an instant gasp of delight from Ethan at just that alone.

	“A-Almost... babe, oh GOD don;t stop!<3” Ethan pleaded in a tone thick with desire, causing Kari to finally take notice of her brother's actions, joining in as they both began to prod their fingers where Tai's had merely been circling before. Just as the telltale twitches began to happen from Ethan's shaft, Tai and Kari both plunged their fingers in to feel Ethan's body shake with the force of his own orgasm, hearing the errant spurts of his hot cum hitting the bed and the wall it sat next to time and again. Ethan himself was unable to so much as squeak, his mouth simply hung agape as his eyes squinted shut tight, his back arching sharply at the mindblowing climax he was experiencing. Slowly it began to end and finally faded, resulting in the bed being absolutely coated in his seed by the time he opened his eyes again.

	“Oh... d-damn...<3” Ethan stammered as Tai and Kari pulled their digits free of his rear, allowing him to sink down and rest against the side of the bed now facing them both.

	“Need a break Ethan?” Tai said in only mild concern until he saw the blissful look on Ethan's face.

	“I'm not 'broke' yet, gimme ten minutes, then you and me are having it one on one.” Ethan smiled warmly at his bovine lover, pulling him in close for a kiss before letting him sit back again, reaching out with his digitigrade footpaw and casually stroking Tai's length. Despite Ethan's words the sheer exertion of the last orgasm had taken it's toll, and his eyes closed before he knew it from exhaustion, foot falling away from Tai's groin.

	“That was fun while it lasted, but I guess you're going to tell him what you've had on your mind when he wakes up, right?” Kari said abruptly, breaking the silence as Tai looked at her in surprise.

	“What, you haven't said it but I know what you've been wanting to ask him, Tai.” Kari said with an understanding look as she got up to leave for the time being, knowing that she wouldn't have to worry about time with her brother or Ethan ever again if things turned out like she and her brother expected.

	“Ask me what, exactly?” Ethan mumbled sleepily, apparently having heard the whole conversation, his eyes merely being closed instead of him sleeping as Tai assumed.

	“I, uhm... I wanted to ask if you minded staying here... living here, with me, I mean...?” Tai stammered nervously, knowing such a question to be a very serious one, but if Ethan agreed it would be worth it. Ethan slowly cracked an eye open to look up at Tai, his only answer in the form of grabbing and holding Tai close before giving his answer verbally.

	“Tai, babe...” Ethan replied as he nuzzled his cheek lovingly to Tai's. “I'd love to.<3” he finished, the two sitting in silence and enjoying one another's company. The thought they'd get to spend many more times just like this one only heightening their happiness, and that was when Ethan gave a surprise of his own.

	“That reminds me, I didn't just save up for that potion either, I got a truck so we could go out someti-... -URK!-” Ethan squawked as Tai's grip cinched down around him excitedly, relaxing before he could get too carried away.

	“Ethan, cutie... you're the best, at least now I know why you were gone so long, this is the best day ever.” Tai said softly, straining to hold back tears of joy in order to speak properly.

	“I didn't mean to get you mad at me if I did, but you're right about wanting to surprise you...” Ethan explained, knowing Tai wasn't the least bit upset by his next words.

	“When did you plan on taking me out then, Ethan?” Tai asked eagerly. 

	The answer to that however is, as with most other beginnings, another tale for another time. <3
