Bicep Kiss

His bicep was just so gigantic, towering over his head, he just had to kiss it and lick the throbbing veins.

Nestled

Nestled tightly between his gigantic pecs, it looks like he’s been doing quite a lot of pec bouncing.

Shredded Tower

This guy is small no more. He used to be tiny, but now is a rippling tower of shredded muscle.

Extra thick

He’s so incredibly thick, absolutely everywhere. He can barely see over his gigantic pecs, and clearly all that immense size feels really good!

Extreme Bulges

This guy’s got some pretty extreme bulges. There’s one he particularly likes the feel of.

Restricted View

If he ever manages to stand up from the lab bed, he’s never going to be able to see in front of him ever again with those gigantic pecs smothering his face.

What are you looking at?

What can’t you take your eyes off? That enormous double bicep peak, his waistband, his eyes, or that huge bulge?

Don’t keep him waiting

This gigantic guy is going to get impatient. Those huge muscles and throbbing veins aren’t going to worship themselves…

Gym Meathead

This meathead isn’t too sure what he needs to do in the gym. I guess that muscle growth formula didn’t do much for his intelligence. I hope nobody would lead him astray…

Difficulty Walking

Even with his huge muscular thighs, he’d be waddling, but with all that, he’s not walking anywhere fast.

Uncontrolled Biceps

His biceps have continued uncontrollably growing so he’s now unable to get himself off the lab table. He doesn’t look too concerned that he’s going to be stuck there for a while…

In shreds

There’s not much left of his clothes after all that muscle growth. I think he just needs to pull off those last few scraps!

Climb aboard

Do you think you could climb aboard that mountain of muscle?!

Holding on

There’s just a few threads holding on to him fully bursting out of those pants!

One button

He was able to do up one single button on that shirt, but I guess that means it’s only one to undo…

Surprised Growth

He can’t seem to believe his size after his growth treatment. Judging by the look on his face, he’s going to be having a very long night…

Too much mobility

He can still reach his hands behind his head, which means his muscles aren’t big enough! He needs more growth!

Monster Lift

I think he’s going to need to pack on even more muscle if he’s going to ever stand a chance lifting that monster!

Animation #21 - Leather Growth

Our next experiment subject is atomising growth formula directly into his gas mask. You just know the results are going to be massive! See him transform from tiny twunk into hyper muscle monster, and maybe he’ll become the muscle meatball he’s always wanted to be…

Another huge muscle morph video available to all �...

Overstretched

His biceps (and traps) are so gigantic, he can’t even reach his hands behind his head - let alone reach the top of his peaks!

Reach

Even fully extended, his bicep peak is absolutely gigantic!

Furry Monster

He stands in front of you, his muscles rippling, his gut bloated with muscle and his chest covered in thick fur ready for you to bury your head into.

WIP - Animation #21

I know it’s been a long time coming, but I’m putting the finishing touches to the next full length animation.

This guy has decided to atomise growth formula straight into his gas mask. You just know the results are going to be massive! Especially if that one vial isn’t quite enough…

Really hoping I’ll ge...

Crawling towards you

He sat up on the bed and saw you. He couldn’t take his eyes off you as he crawled forwards. After all that growth, he needs satisfying right now!

Bloated Beast

This gigantic bloated beast is ready for action. Looks like he’s been dosing on the roids too, judging by that huge bloated roidgut.

Pump him up

The muscle growth formula makes these guys extremely sensitive to any extra testosterone. So, do you think you can pump him up any more? He can still move his head, so lots of room for growth.

Squatting

Squatting on the gym floor whilst gripping the gigantic peaks of his biceps. Although he can’t quite get deep enough with his squats when he’s packing this much size… He clocks you checking him out. Maybe you could add some weight from him by climbing that rippling back?

Size Comparison

As he pulled off his top, he flexed his bicep which formed a gigantic peak. Looks like he wins the size comparison in every way…

Collapsed

His legs seem to have given out under that enormous weight. He just had to keep pumping himself bigger in the gym until his upper body was so overdeveloped his legs gave out. Looks like he’s been roiding too judging by that bloated gut.

Top Heavy

Looks like 90% of his growth formula was shot straight into his back and biceps. He’s so top heavy he’s probably going to have to stay on the operating table.
