Late Night Locker Growth (Patreon)

"Looking for this?"

It's the dead of night. You've just realised you left your bottle of Hulk Juice in your locker back at the local gym. Hurrying down, you're quickly confronted by your arch-rival. His naked body's pumped as hell, his cock swelling in anticipation of what's to come. You see in his hand a familiar bottle of glowing green juice.

"Payback time."
