In this follow up to Julien At The Pool 3, Julien heads into the locker room to change.
He had just changed out of his sweat pants, when the dumbstruck Julien found himself getting turned on by the atmosphere. When he gets turned on, Julien grows bigger. He grows without even realizing it too and when he does figure it out, he has to flex. He tends to wear stretchy clothes for situations like this, but even they couldn't contain his new size when he flexed so hard.
