The gluttonous giant was so ginormous that he didn’t notice Mars slip into his belly button. He was too distracted looking at his next snack: the Earth itself!

Until I find my symbiote boyfriend for the perfect glistening skin and basically walking around naked just covered in him... this will have to do.

Eric came out here for some sunshine, but now he’s sitting on the bench trying to act normal while his pecs feel like they’re about to burst. He laughs about it, loving the sensation, but he’s trying to find someone to come and help him release all this fullness before he explodes! Anyone out there?

“Not to be vain, but life’s so easy being this sexy and huge! So many horny men would throw their life savings away just for the chance to feel up my body for a few hours. The fuller my muscles get, the emptier their wallets become.”

Me: I’ll do a quick chest workout, nothing crazy.
Also me: I accidentally became a massive, human dairy factory.
Now every step feels like moving a pair of mountains, and I can’t see my toes without a side mirror. But come on! You gotta love these milky tits! 🍼💪😂

“I don’t know if I’m gonna make it through No Nut November guys. It’s only been ten days and look at me! As times goes on, it’s like my cock and balls are protesting by getting heavier and more sensitive. I spend every hour gooning absentmindedly while growing and waiting for the perfect orgasm.”

A familiar Husky has gotten his hands on a few boxes of Pump-Up Pills.

Anon comic commish
Panel 1; Greg has delivered several boxes of Pump-Up Pills to a very excited Husky Panel 2; the husky tosses a handful of the pills back Panel 3; they instantly take effect, causing his neck to swell and thicken Panel 4; the growth spreads through his chest, pecs ballooning Panel 5; they swell up even bigger, pumping up like air bags and shredding his shirt Panel 6; the husky feels a tingling in his arm Panel 7; just before it bulks up and he has to flex his new glorious biceps Panel 8; one leg of the husky’s jeans bursts open as his legs grow Panel 9; the door opens just as his bulge drops free Panel 10; the Doberman is stunned as a shadow looms over him Panel 1; the Doberman stands stunned in the doorway, looking up at his pumped up buddy Panel 2; the husky scoops up the Doberman, pinning him against his pecs Panel 3; with just a flex of his biceps, the husky forces his buddy’s mouth open and pours in several pills Panel 4; while the Doberman struggles to swallow, the husky grabs one of the boxes and starts emptying its contents into his mouth Panel 5; the husky bwooms into the ceiling while the Doberman’s pecs and bulge balloon out Panel 1; the house starts to feel pretty cramped as the two canines grow against each other. Panel 2; outside, the roof begins to buckle, a tuft of fur breaking through Panel 3; the husky’s head breaks through the roof Panel 4; most of the upper floor has been demolished by the hulking husky, the Doberman tumbling out on onto the front yard. Panel 5; the Doberman tries to waddle into the street, even as his friend’s cock rapidly grows even bigger than his is Panel 1; looking down on the neighbourhood the husky and Doberman continue to grow Panel 2; their huge bodies swell bigger and bigger, covering even more of the neighbourhood Panel 3; their growth continues to escalate as they quickly grow even bigger than mountains! Panel 4; their growth finally starts to slow as they begin to outgrow the continent Panel 5 & 6; close ups of the Doberman and husky’s heads buried in their immense muscles

Unaware of the virus that was altering his brain and body, Leon Kennedy didn’t question his revealing new uniform or the way his ass jiggled considerably with every step. He had missions to take care of and wouldn’t let his mouthwatering derrière get in the way!
