The New Assistant
One of the major troubles of being a big hyper is how the world interacts with you. Sure, I hear lots of idle fantasies from my friends and admirers online about how great it would be to have a dick as big as mine, all of which begin at arousal and end at orgasm.
Out in the real world, though, you're at best facing muffled derision from onlookers when you go out in public--at worst, you may be entirely homebound.
My name's Alto and I have been in the latter category for my whole adult life. I'm not house-sized by any stretch of the imagination; if I were bipedal I'd probably be able to haul myself around without too much trouble. But instead, I'm a big shaggy mutt-taur whose legs haven't been able to reach the ground since puberty. My dick runs along the whole underside of my barrel even at its softest, and is generally thicker around than my own rather hefty body.
Yeah, I'm fat; it's not like I get a lot of exercise. Thanks to the wonders of technology I'm not totally hopeless when it comes to mobility--I have a little accessibility cart I can haul myself into to get around the house, but it doesn't have a lot of range to it. At least I don't need help getting to the restroom.
There are a lot of things that I do need help with though--luckily for me, I've got an assistant.
Well, I call him my assistant. I more thought of the tubby polar bear as sort of in the halfway space between caretaker and boyfriend. It may not be the most ethically luminous place to be, but if your job is to take care of someone with a big dick, it's also a little important that both sides actually enjoy it.
Marsh enjoyed it a lot. Not just the regular milkings to keep me from getting too pent up, not just the nights he spent keeping me company--he even seemed to like the simple cooking and cleaning.
And then one day, it wasn't him that showed up.
The stern wolf who knocked at my door that morning introduced himself to me as Dino, and said he was taking over while Marsh was "on leave", though he wouldn't say why the little round icebear had gone, or how long till I could expect him back.
After I made a quick call to the agency to make sure Dino was legitimate (and unsuccessfully trying to get details about Marsh), the wolf laid down his work bag and gave me a thorough inspection, taking measurements and vitals as my balls began to ache--my dick had a mind of its own sometimes and having a disappointing stranger in my room had done nothing to reduce my morning wood.
"Um," I started, feeling a bit awkward. "Will you be helping me with my, ah, morning release?"
The wolf frowned at me and reached into his bag, pulling out a strap with a black box about the size of his fist attached to it, and started tying it behind the head of my cock.
"Ah, come on man, that's not--"
He ignored my protest and switched on the vibrator.
I tried to reach for it, but the end of my cock is not in range of my arms when I'm hard. And the vibrations would definitely keep me hard, even though I could tell they were too weak to actually get me off.
"Dino, please... this isn't--"
The wolf looked at me with some confusion, then reached to turn the vibe off. "What? This is the procedure."
"Yeah, but this isn't about a procedure, it's about a person. Look at me."
Dino met my eyes and I stared him down.
"I don't know if you're new at this or what, but regardless of what they focussed you on in school, I'm more than just a sack of meat with a dick."
Nothing in his expression softened. I sighed and leaned over in an attempt to reach for the phone again.
"Wait--" he said, as I started to dial.
I lowered the phone. "Ah, you do have feelings."
He hung his head. "I don't know what you want, Mister Alto."
"How about we hold off on the milking for now. I think you and me need to get some bonding time in first. C'mere." I patted my flank, offering him a seat by me.
He looked a little uncomfortable as he nestled in against the big soft beanbag that was my balls, and I turned on the TV.
It took a couple of shows before Dino loosened up a little, nuzzling up to my hind leg. I paged through the list of recommended movies and picked something bland and inoffensive, figuring that we wouldn't be paying attention to it shortly anyway.
It was only a few minutes before the wolf started idly stroking my shaft, helping it stiffen again. I didn't push him or say anything lewd--I wanted him to be fully committed to it in his own mind.
And after a bit--when I was fully hard, my dick reaching nearly all the way to the other wall--Dino got up and crossed the length of my dick, putting his soft furry arms around it and nuzzling at my piss slit, which had started to leak heavy gouts of pre.
"Wanna ride it?"
He shrank back a little, just at the thought. "Your dick is bigger than I am. I couldn't--"
"Swallow down a little more of that pre before you tell me what you can and can't do."
The wolf shrugged and slid his tongue along the head of my shaft, slurping up all the pre I'd been leaking so far before returning to making out with my slit.
"Nnf... try sucking it now..."
He looked at me a little skeptically before opening his muzzle wide in what should have been an obviously futile attempt to get his mouth around something bigger than his torso.
His jaw dropped--literally, to the floor--as he found his mouth opening far wider than he could have imagined. I nudged my hips forward a bit, pressing my cockhead into the cartoonishly-gaping maw.
He went to work suckling on my cock as soon as he'd grokked what had happened. I loved watching his body stretch around my member, the smaller wolf's whole body easily expanding to accommodate my girth as he worked to throat my enormous cock.
Enjoyable as it was though, I wasn't about to let him get me off that easily. "Dino... you want this load up your ass?"
He didn't need any further prompting, pulling his muzzle slowly off my dick till it was free to contract back to its ordinary proportions. He rubbed his jaw a bit as it slid back into place. "Wow," he said. "I can see why Marshall liked it here."
He stripped out of his clothes--which as usual weren't affected by the stretching--and got back down on all fours in front of me, tail up.
"You'll need to get yourself started," I said. "Thrusting won't work well and I can't reach you from there."
He looked back at me and I could see him pondering the logistics of what he was doing before tossing caution aside and grinding his soft fuzzy rump against my cockhead.
And as my precum worked its spell on him, his hole began to stretch. I heard him gasp out softly as he pushed back, his body stretching wide with slick warping noises as his incredibly tight hole let me in.
He slid onto my dick like a warm, furry condom, my dick lengthening him again to toony proportions as he managed to fit more and more of me in.
He felt really good. Marsh had gotten used to my girth over time--insofar as that could be said to be possible--and I'd almost forgotten how it felt to break a new ass in.
And now Dino got to learn what it was like.
As soon as he was in reach, I grabbed hold of his legs and pulled him further back onto me, the poor wolf yelping in surprise as the head of my dick forced itself nearly all the way through him, his own head wildly distorted by the underlying shape of my dick.
"Now we're talking."
With his legs as handles I started sliding the wolf up and down as much of the length of my cock as I could reach. I could feel the tight tunnel that was his body wriggling around my shaft with each "thrust", his hole loosening and growing slicker as more of my pre flowed into him.
I felt my knot forming under me, with its maddening insatiable need. Even with all the stretchiness my fluids could provide, I'd never been able to fit it into anyone.
That doesn't mean I never try.
I was able to pull Dino further and further onto my cock, reveling in the feel of his insides and the anticipation of my much-needed release. Inch by inch, I tried to hold back my climax.
"Oh pup, gonna fill you up..."
With a powerful effort that made my arms ache, I pulled the wolf's rump flush against the front of my body and locked my forelegs around his hips. He was burbling senselessly in an ecstasy of fullness, a heavy stream of pre flowing from his muzzle.
"Gonna stretch you so, so wide..."
I growled deep and thrusted, my hind legs straining to push my shaft forward as my forelegs held him in place. The wolf yelped as he felt the mass of my knot pressing against his hole, clearly surprised I'd try to stuff something the size of a small car up his ass.
"Hold your breath..."
I gripped my dick through the body of the stretched-out wolf and kept pulling. I heard myself whimpering as I strained to force my knot into him. He was so warm.
I kept thrusting as hard as I could, and I felt his hole open up further. He was so tight around my shaft I knew I couldn't hold out much longer--my arms were shaking, my dick was throbbing, and even though my knot was still untied, I could feel the need to release building up.
"Here it comes--"
The first shot blasted all the way through him, leaving a thick splat of cum dripping all down my far wall. I felt him struggle to get his maw shut before the second shot made its way up my cock, and he succeeded to the point that you could see his head deform with the release of my heavy load.
Each successive shot after that only served to round out his body, making him more and more like a warm, sloshy cum-filled balloon, and I leaned into the soft-furred ball of wolf as my body wound down from its exertion. I wanted to congratulate him on taking nearly a quarter of my knot, but I just held on to him as my cock softened enough to slip out of his rump, which immediately squinched back to its original tightness.
I spent some time stroking the big cumball till he seemed like he might be able to speak again without blurting out half the seed that'd been filling him.
"Thank you," I said. "That was much more comfortable than some silly vibrator."
He tried to rub his massively-bloated gut, but couldn't really get his hands past his chest. "For you, maybe. Not that I'm complaining. That knot of yours is..." He closed his eyes a bit wistfully.
"You did great for a first attempt. I bet with a bit of practice you could take the whole thing." Man, I hope so. "And then you'd really get me cumming."
"Mmm," he said. "I can definitely see why Marshall liked it here."
