He fell back against the floor, going crosseyed with the amount of pleasure he was feeling as his penis started to grow larger. The skin of his cock had turned green but now it was starting to look transparent as it grew taller, still squirting green slime against the ceiling.

Inside his penis looked to be dozens of green orbs swirling around, seen through the transparent green skin. He couldn't fathom what he was seeing or even care as the intense orgasmic delight had him in a fog as he felt his cock twitch.

Soon, along with green slime, many glowing orbs started to erupt out of his cock, giving him even more pleasure as he had a stupid smile on his face, unable to stop what was happening to him while his monstrous penis wiggled and squirted those things all over the place.

Soon all of them were in the air, floating in a circle, lighting up the ceiling as they spun. His penis was still glowing as the original was still inside him, controlling his penis as his brethren began to disperse. They disappeared through the walls and the ceiling, seeking out other sexual organs to give their creator more power.
