When your housemate is a wicked scientist with goals to grow, surely drinking all their experimental potions is a good plan... right? Looks like it worked out just fine for me~

The FULL ANIMATION can be found on e6, Itaku and the Hub! Enjoy!

After a long day with both his jobs. Nothing Larry likes more than to fill up and eat from the fridge. Thankfully his partner made sure to stock the fridge again after Larry ate everything for breakfast.

“Having second thoughts? Don’t worry, I won’t bite. There’s plenty of room in the shower for the both of us. My juicy ass will definitely pin you against the wall a couple times, but I have a feeling that’s exactly what you want.”

(1/2) Comic Commission for an Anonymous commissioner! Both OCs find a spring in the middle of their adventure. Without knowing that it was a magical spring, which had growy effects on any adventurer that drunk or bathed in it!

After getting swarmed by spiders and mushroom sprites in the difficult mines, Farmer Greg needed a trip to the spa to heal up. He was pleasantly surprised to find Alex having a soak after his workout.
Something something, luckily he's got some good floatation devices!

Here's the Participation Prize for @musclechubboi.bsky.social , one of the contestants of my MG Writing Contest! Featuring the characters in their story! The big bully becoming and even BIGGER bully throughout the story!
Thank you for participating!

The smaller man is surprised that his old bully ends up sharing the same dorm room as him.

Cornered in an alley, the now bigger bully forces his smaller roomate to worship his massive muscle gut.

The massive bully, right after eating a bunch of people that got dragged into his lair, picks up his lil' roomate to lick him and tease him.

To all skinny guys out there, check out Pump UP Pills!
*results may vary*

Panel 1; A skinny Jacob is getting bumped by a larger, buff Phil
Panel 2; Jacob puts a pill on his tongue
Panel 3; Instantly Jacob's neck bulks up, thickening with muscle
Panel 4; Jacob's upper body begins to swell up bigger and bigger, his pecs blowing up and covering his face, one arm pumping up while the other one grows at a slower rate
Panel 5; Jacob's speedo begins to twitch and bulge
Panel 6; Jacob's bulge BULGES a LOT more
Panel 7; Jacob is now hulked up and huge, pumped up with massive muscle and a very full poser

Greg is appreciating Jacob's muscles, but the fox's tender touch pushes the huge bull over the edge and he starts to cum

Here's the Participation Prize for YS, one of the contestants of my MG Writing Contest! Featuring the characters in their story! One of them going through a growth spurt in a bedroom!
Thank you for participating!

One of the characters starting to grow after kissing.

Big bf growing so big, that he hits his head on the ceiling, making him fall down on his butt.

Big bf, filling up the room more and more with his size, starts to get more in a "mood", stripping down his smaller bf.
