It had started with a knock from the stall beside me. To my surprise, a dick slid through a conveniently placed hole in the wall. Next thing I knew I was on my knees going to town on some stranger's junk. 

I was incredibly excited. I couldn't control by breathing very well and took deep, shaking breathes on this guy's dick. I'd never tasted anything quite like it, and my tongue shivered across his sensitive skin. He constantly made these insistent grunting noises on the other side of the wall. They spurred me on.

I felt something touch my knees. It had weight to it, and I figured it was a backpack or something. I looked down and immediately dropped off cloud nine. It was his ballsack, massive and furry. I'd heard about people like this, and I knew I was in trouble. I pulled my head back, stood, and began to gather my things. I heard his stall door creak. Then mine burst open and hit me in the back. I fell forward and just managed to brace myself against the far wall. 

His arms were around me in an instant. He was incredibly strong. I felt an intense pressure as his dick, dwarfed by his enormous balls, pressed into me. We cried out together for different reasons. My knees trembled. He was unrelenting, deaf to my cries and pleas. I could feel the warm, immense weight of his sack pressing down on the back of my legs.

It must have been hours since then. I rest on my stomach, now roughly waist-high for my panting, sweating assailant. My sides press agains the stalls on either side, and my face is forced into the back wall. The toilet has long since been buried beneath my gargantuan body. I can feel him trying for ever deeper depths, standing on his tiptoes. The sounds my body makes as he assaults it are sort of taut and jagged, like slapping a balloon filled with water. 

I ache. The entirety of my skin tingles in sort of half-numb pain. I can't really breathe. My chest burns with the crushing weight of his seed. I can feel inevitability beckon as my body ceases to creep outward - but I can still make it. If he'd pull out I'd more than likely be fine. He can shoot the rest across my back. Hell, I'm willing to take a few shots to the face if he'd just stop now. I open my mouth to tell him and manage only to gurgle as gallons of cum flow down my chins.
