Muscle Growth Experiment - Part 2 (Full Version)

Hey there folks~! ^^

It has, as always, been a challenging but fulfilling journey in bringing these stories to life :)

I have completed the second part of the Muscle Growth Experiment story.

Thank you all for the support while I worked on it! This was a fun one. See what happens when Gavin grows to epic proportions, all while Alfred is seemingly helpless to do anything about it. But... maybe he doesn't want to... ;)

Let me know what you think~ ^^

So get your ideas ready~!! ;)

Is there a way to get something better than sprout video?

That was great, love the shot of his dick and balls at 0:21!!! I wish they grew more tho, a god like him needs a massive pair of low hanging balls. Definitely do a part 3.

what a great surprise in the middle of the week haha. the quality of your animation is so good! I'm not a big fan of macro but gavin's insatiable lust for more strength and growth was so hot

Wow, I'm impressed as always by your work—I loved this one. I’m so happy you continued one of your videos—I find it exciting to see the guys keep transforming. I especially enjoyed the growing of more abs and the jiggle of the pecs, and the interaction with Alfred and the pose he makes at 2:14. Drips of sweat are cool too. I really like how he keeps asking for more and more, he deserves it. To be honest, I’d really love to see a Part 3 or a continuation of their story. If a tiny vial could do that, imagine what those huge vats right at his feet could do—I want him to drink them all ! Godhood at his feet ! haha Bravo again Taka

Really enjoyed the first part. thought the second part lacked the excitement and action of the first part, I didn't really feel it added anything.

Love it 😍 worth the wait, Gavin became a towering Muscle God.

I enjoyed it but I’m a little bit disappointed, I wish there was a bit more interaction between Alfred and Gavin and that Gavin would end up growing too (more one the fatter muscle side lol) because Alfred forced him the serum. This one felt a bit stagnant at times.

I really love it! I would've love to see Alfred grow as well after Gavin giving a massive amount of load. But other than that I love it. Can't wait for the next animation. :) I think you could make third part of it. ;)

Man I would be so down for a part 3, i mean there is giants vats of serum in the lab as we saw in part 1 or 10 years video. Gavin should drink them all and become a God

Was NOT expecting this to drop but oh my god did it not disappoint. Fantastic work on it Taka! Absolutely loved the first part and this one hit all the right buttons again! Hopefully this isn’t the last we’ve seen of Gavin! (And maybe Alfred can join in the fun!). Thanks for knocking this out of the park!
