GrowthINC introduced a new scheme in their laboratory, the GrowthMill. The longer a subject runs on it the bigger they get. Andrei of course trying to stay ahead of everyone made sure to get first use of it.

It had only been tested by someone physically unfit who could only manage 10 minutes, there was no way of knowing what it could do to a bodybuilder!

Andrei had already packed on some serious size after the 10 minute mark and had no intention to slow down anytime soon, however his shorts were definitely starting to strain from his sudden mass increase.

Not wanting to stop running he ripped them off, allowing him some more breathing room. Thankfully GrowthINC provide a super stretchy poser with all their experiments.

After 45 minutes Andrei was becoming exhausted, not only from the long run but the sheer weight of his body was a lot of effort to keep holding up, especially with his huge thighs constantly rubbing together now after each step.

So many to choose from! I'll try to name guys that aren't the typical Jordan Torres/Mike Thurston that come up every single time. In no order,
