I couldn’t wait any longer.
My thick bear cock was aching, leaking precum down my hairy thigh. I found Ethan at the bar, a cute, smooth, skinny twink who looked nervous but excited when I pressed my massive gut against him and invited him back to my place.
As soon as we got through the door, I had him bent over the bed.
I shoved my fat, throbbing bear cock deep into his tight little hole in one powerful thrust. Ethan moaned loudly, gripping the sheets as I started pounding him mercilessly, my heavy hairy belly slapping rhythmically against his smooth back.
“Fuck… you’re so tight,” I growled, lost in the pleasure.
I had no idea Compound B was still contagious.
I fucked him harder, deeper, grunting like a beast as my heavy balls tightened. When I finally roared and unloaded inside him pumping thick ropes of hot bear cum deep into his guts,I thought that was it, that this would be a pump and dump.
Then Ethan started whimpering.
“Oh god… something’s happening…”
The changes hit him fast and hard.
It started in his ass. I felt his hole suddenly clench and pulse around my cock as it loosened and deepened, becoming a proper bear hole. Then his spine arched as his back broadened, shoulders widening with audible pops. His smooth chest began to itch violently, dark, coarse hair sprouting rapidly across his pecs, spreading downward in thick waves until his entire torso was covered in a dense, musky pelt.
Ethan gasped as his belly surged forward, swelling dramatically into a huge, soft, rounded gut that hung heavily. Thick hair continued to spread over the new belly, covering every inch. His nipples darkened and thickened, becoming sensitive bear tits that begged to be played with.
“Fuuuuck!” he cried out, voice cracking and dropping into a deep, gravelly rumble.
His arms ballooned with fat and muscle, biceps thickening, forearms growing strong and hairy. His legs followed his thighs exploding in size, calves rounding out, everything covered in thick fur. His face pushed forward, jaw squaring off as a full, bushy beard exploded across his cheeks and chin, he looks much older now. Made even older as his hairline receded slightly, giving him that perfect mature bear look.
His cock was the last to change.
It swelled dramatically in my hand as I reached around to stroke him growing longer, thicker, heavier, until he had a fat, uncut bear cock leaking against the underside of his new massive gut.
When it was finally over, Ethan , now a big, hairy, bearded bear just like me, collapsed onto the bed, panting, his enormous furry belly rising and falling with every breath.
He slowly sat up, staring down at himself in disbelief. His big hands roamed over his heavy gut, squeezing the soft, hairy flesh, tugging on his new thick nipples. His fat cock twitched hard against his belly.
“What… what the fuck did you do to me?” he growled in his new deep voice, looking equal parts shocked and insanely turned on.
I stared at the massive bear I had just created, my own cock already getting hard again.
“I didn’t know it could spread like that…” I admitted, voice thick with lust.
Ethan looked down at his transformed body once more, then back at me with hungry eyes. He gave his heavy belly a slap, watching it jiggle, and grinned.
