Coal began to quiver, in a mix of terror and delight. The pulsating veins that once only roped around his new fat demon dick, had visably begun to snake outward...like roots of a great tree searching for water to bring it life.
It was mesmerizing. The veins coarsed all over his balls, completely covering Coals sack in pulsating warwth. They also began to branch out up into coals abdomen, and down into his scrotum.
"Oh god...Xan, this is...TOO intense!" Coal stumbled backwards and braced himslef against the wall as he felt the power spred to his inner thighs and ass. The rose up his torso just under his chest when they stopped.
"Wow...ya know, boss, I really have no complaints. It looks marvelous..." Xan cut himself short as he spied something unusal "Oh crap! What in the name of hell is that?!"
the two of them then noticed that the massive pulsing veins anchored all over Coals mid section waist and thighs were now reversing the flow of blood. Instead of pulling it into the fattening cock, it was being forced back into Coals body. From the dick itself, a black ooze started to seep through the veins, contaminating every capilary with a dark syrum.
"No! Make it stop! Xan, get me the knife...I have to stop this before..." Even as Xan bolted for the kitchen knife, Coal knew it was too late. He felt the erotic surge of power as the forboding blackness filled the veins that led into his balls, his scrotum, and legs. Even the filling nourishing sensation as it climbed up his waist.
The 2 foot Demonic cock stood high and proud now, almost glowing, as it continued to pump Coals body full of the the fluid. His balls began to expand, stretch and swell, now transformed into a factory for the black demon ooze. Coal could feel the veins digging into his muscles up into his chest, down into his calves, like tubes inserted into his flesh. His body began to swell in response....
