cumsplosion 

An enormous amount of jizz to come out during masturbation or sex.

Carl was jerking off to some porn when he finally cummed. A hot load of jizz coated everything in front of him, a cumsplosion. He didn’t stop though. The stream of hot jizz didn’t look like it was about to stop. The stream kept coming. Carl tried to stop it by holding his dick tight but it hurt like hell. He stepped out of his chair and it still rushed out. The dripping stream didn’t stop. He tried putting on pants but filled up with cum. He went out naked. He bravely stepped out of his house to try and get help but then the door locked behind him. His cock dripped with cum faster and faster. His raging boner was rock hard. He then saw his crush walking toward him.
