You can't even remember what your job was now. Something... with computers? You drank coffee at some point... sent a fax OH GOD.
Hau is plugged into you and can tell when your thoughts are wandering. The very moment you think of escape, ZAP, he sends another pulse of pleasure through your shaft util the thought slips away. His numberless tentacles aren't just pumping and coiling and polishing your dickhead, they're forcing their way into your body through every orifice, plumping you up wether you like it or not. An oblong, twitching bulge under a shiny, creamy fox belly is the only evidence that Hau's body has a passenger. You'd be more traumatized if this isn't, in a way, exactly what you signed up for.
"It's a beautiful day, Luke." You watch your arms turn as he admires his vulpine claws. "Why don't we go for a walk? I have a friend I'd like you to visit."
Your bodies travel together effortlessly. You feel lithe, weightless, powerful yet lean. Being a fox has its advantages, though you're not sure foxes normally have liquid latex pumping into their throats every few seconds. Your mouth suckles at thin air, either to clear the phantom invader or to push it further in. There are a few people watching as you pass, some human, some anthro animals. It's hard to judge what they think right now, because the wire in your brain says you don't care.
Hau jumps down a rocky ravine in a single bound, landing in a three-point pose. He guides you towards a cave opening in the side of the rock wall which feels oddly familiar. A few steps within the cool darkness, a silver latex tiger awaits you.
No, calling him merely a tiger is underselling him. He looks like another symbiote, but instead of the human-sized friend you're wearing he stands over three meters tall, an impossible giant. He sways and springs as he walks, legs like pistons as he carries himself with none of the weight he looks like he should have. "Good for you, Hau, you found another sucker."
"Nuh-uh, he's a friend, not a prisoner like yours."
"You keep telling yourself that, Hau." Up close, his muscles seem unnaturally perfect, statuesque and sculpted. "Cut the crap. You know what we have to do to keep on living. Why not make it fun?" The tiger grabs at Hau's crotch- YOUR crotch- and both of you gasp. Hau's symbiotic rubbing and frotting was one thing, but this unnamed tiger man clenches you with rock-solid force. This isn't a gooey soup like you've been swimming in, but a crushing metal piston with almost no give to it. Hau dutifully lets your penis pop out in its own sheathe... only for the tiger to push it back into a bulge.
"Oh, no no no. It's my turn." He waits for you to move- you realize after a moment that Hau is letting you take the lead for this one. Your foxy hand grasps at the tiger's crotch, feeling the rubber surface of his smooth, featureless crotch while he lets out a huff. It's like a springy foam shell over... wait... deep in there, you feel a bump and hear a muffled moan. He's got a man inside him too! They're buried so deep that nobody would even guess unless they were searching. "C'mon, boy-toy. let me take you for a spin."
"Yeah, c'mon Luke, it'll be fun!" A pair of hefty tiger paws push you down on your knees. You could swear your kneecaps suddenly have slim pads protecting them now. Neither you nor Hau have a moment to even react before you feel an enormous anthro penis enter your ass! You drop down to your elbows and brace yourself against the ground, fox fangs clenched and growling. The wet stone below you is solid, and the shaft within you is harder still. It takes only a moment to hit your g-spot, flooding you with a foreign euphoria!
Pump, pump, pump! You can feel the tiger getting engorged with you and pushing deeper within you, but your own dick is another story. After days of being milked for sustenance, you have almost nothing left to give. Your balls ache, sputtering like the last hair's breadth of gunpowder in a firework. A moment of doubt enters your addled mind as you wonder how you're going to come even one more time.
But then the tiger stands, lifting the two of you up like nothing more than a stuffed animal. You remain impaled on his stick, a treat for him to enjoy. Powerful paws pull you an inch or two off of him, and then DROP you back down- hard. Hau's body rocks and wobbles like the fucktoy he was built to be, like the fucktoy that you've embraced being. The giant slams into your prostate again... and again... and AGAIN. Against everything you knew about biology and your own limits, you feel an erection building underneath Hau's tight embrace. Both of you moan as you know what is going to happen-
And you come-
And a few seconds later, you ride the high back down to earth. Now you know for certain that you hit your physical limit. Hau, on the other hand, stands back up as if none of that even happened. He braces his skinny paws on the tiger's chest, jaw clenched. "Hold on Luke, it's about time you got to see this."
You're... getting bigger? No, not quite. You feel your hands slipping away from Hau's paws as his arms become longer, burying your fingers somewhere in his wrists. Your former humanoid feet stretch out into digitigrade springs, with your ankles resting in high heels and your toes nowhere near where his fox paws end. All around you, sculpted latex muscles expand outwards from your body- not quite the bodybuilding physique of the tiger, but instead a lean swimmer's frame. You test the limits of your new symbiotic body... and find that you can't. Hau's old coating felt like pushing against a rubber band when it resisted, but this is like a shell of concrete. He really is as strong as he looks.
"Hey Luke, how do you like it? This is about as big as a symbiote can get without burning too much energy to keep it going. You and I are going to enjoy this..."
