"I know this sounds weird but..." I began to asked sheepishly. "Could you make me fat? Not in, like a dangerous way. I don't want diabetes or heart disease or shit like that"
Runt gave a surprised look.
"Huh, didn't expect you to say that" he said, grinning. "But a wish is a wish"
Runt started walking towards me and I started to back step.
"Wait, what're you gonna do?"
He pushed me back, hoisting me up onto the table, and bent down pulling my underwear down as he leaned in. His long, forked tongue snaked out, and slapped my ass cheeks, giving me a jolt of surprise, setting my cock throbbing.
"Oh fuckk..." I groaned, feeling Runt work his way around my ass cheeks, and then tickle my hole. I have never felt anything like it, and my balls shuddered in appreciation. Then Runt was rising, licking my balls, licking my cock, as his hands groped my ass, pulling my cheeks apart, his own hard member pressing against them, rubbing pre on my hole.
I groaned softly, and gripped Runt's small shoulders, feeling the firm muscle of his delts, holding on as he got to work, slowly pushing his tool up my virgin ass. I took deep breaths, as unbelievable pleasure filled me, Runt's not-so-runty cock filling my ass with load after load of cum. And with every thrust, I cried out in ecstasy, pleasure racing through me. And with every load, I began to swell.
I felt my body growing outward, getting bigger, rounder and softer. I watched as my belly distended out from a modest bump, to a round firm gut. I groaned appreciatively, as my ass grew wider and rounder underneath me, stretching the waistline of my already tight underwear, wich began to split at the seams. "Fuuuuuuck..." I moaned, as Runt laughed.
"You like this? You like having a dick up your ass? You like how it's making you into a fatty?" he teased. I nodded vigorously.
"Oh fuck yes... I can't believe how.... amazing this feels!"
I grinned back at him, watching as my chest inflated into a sizeable pair of man boobs. Runt's eyes flashed and he grinned excitedly, as he reached to caress my round tits, his talented fingers sending shivers through me. I growled appreciatively, and grabbed his tight waist, holding trying to pull him deeper into me. He laughed, and started thrusting in hard, while pulling on my nipples, squeezing and twisting them, the nubs growing perky and soft, with a wide areola to match the mass behind it, as sparks of pleasurable agony racing through me as he fucked me raw.
The faster he fucked me, the more he came, the quicker I grew. Runt laughed delightedly, and rammed himself home as far as he could, his big cock exploding inside me, filling my ass with his seed. I howled as my body swelled further and further with pound after pound of soft jiggly fat, feeling it slosh around inside of me.
As my underwear snapped off from around my obese body, my cock sent a fountain of cum into the air,
nothing compared to the flood Runt was delivering up my ass, the sticky goo inflating me like a water balloon. Runt chuckled, and began to lick my cum off of my huge soft body, his tongue sending shivers through me, his cock still planted firmly in my ass, pushing in the last of his seed.
Slowly, Runt pulled out, and I stood from the table, which creaked dangerously beneath me. I looked across the room, at the mirror, and gasped. I was massive. Every part of me had gained weight, my massive round belly pushing forward into my lap, my big round melon sized boobs resting on top. I couldn't help but smile, as I heaved myself to my feet. I looked down at myself, giving my huge belly a shake, as it jiggled and wobbled with every movement.
"Shit I could get used to this" I said, turning to check my huge round ass. I was now 350 pounds obese , my cock barely visible underneath my huge round belly. I guided my hands up the round mass of my gut, feeling the hairs on my treasure trail, and up to my huge round man tits, fat pink nipples sitting on top.
My face was fat too, with big round cheeks and about 3 chins. I looked at my hands, the fingers like fat sausages. I turned to see Runt, waving a glowing red hand as the mess of cum vanished, before he turned back to me.
"Glad you approve" said Runt, smiling admiring his handiwork. "Gotta say it's been a while since Ive done that to someone"
