Run a hand over it

The weight of this enormous dick was overwhelming. If he had known this morning that he might be standing over his own body-weight in cock, well, he wouldn't have known what to do. But now, being here, he didn't have to imagine anything. He could feel it. Felt his balls churn with cum. liters upon liters. His legs, shifting from side to side to keep balance, could not get away from the warm, soft mass that pressed against his thighs and calves. Even with his enormous balls resting on the cold tiles, the heat of his churning sperm was more than enough to stop the chill. With so many nerves, he could feel every single tile beneath him. He could feel the way his balls sunk into the cracks, even the smallest of which was plugged by his enormity. His cock, on its own bigger than his whole body, began to leak a glob of precum. He watched the clear liquid slide out of a hole that could fit his entire hand as it splattered against the tiles. He felt a tingle erupt through his whole body as the weight of the precum fell away from his cock, released by gravity and replaced not a moment later by another bead of cum.

John was breathing heavily now, his ribs clear through his skin. His muscles flexed as another ripple of pleasure echoed from his beautiful monstrosity. His newly gained pecs straining to contain a heart that felt ready to explode. He reached a hand out, trembling like a leaf as the pleasure and awe racked his body in equal turn. His finger found a vein, resting against it. He seemed so small, compared to this cock. It was like an entity, separate to him but still so clearly of him. He pressed his hand down, and moved.

All noise caught in his throat as a wave of pleasure overtook his entire body. His cock, already rock hard, swelled further as gallons upon gallons of cum streamed out like a creamy waterfall. Inside his mind, John was blank. No thoughts overtook him, no emotions could be mustered. All that was there was the pleasure. It would take minutes of cumming and blankness before he would realise he had been screaming in pleasure.

He didn't know how long had passed. It felt like he'd been cumming for hours. He could hear a conversation outside, something about a cleaner. He looked down, and sobered up a bit. The room was flooded. His enormous balls were now half submerged in a river of cum. It was filling the room to the brim, and had even coated the walls. The smell of sticky, salty fluids hit him like a truck, jolting him further back into reality. Had it really been only this much? With nuts like these, he reasoned, he should've taken off the roof! He remembered his new abilities, and reasoned that the next time he did this, he would give himself nicer smelling cum.

But what was he going to do now? That was his family out there, he could tell. What was he going to say happened?
