A black monster to rival Adam's

Devon sat there panting as his body was rocked by Adam's Growth-X enhanced cum. His average cock had already grown somewhat since the gym incident, but now with so much cum coursing inside of him and soaking into his skin the change really took over. With every pulse his cock thickened, the veins bulging obscenely on its side, and eventually it started to lengthen to enormous sizes as inches and inches of cockmeat **** their way out of his body and added to his black monster. Finally with one almighty moan Devon's cock maxed out at a mouthwatering 14 inches of pure, thick, slut-making power.

Adam first looked on with pride, still recovering from his own mind-shattering orgasm, while his cock rested against Devon's muscular thighs. But soon that look turned to one of horror, of shock and then one of pure desire. It was so big and beautiful, and those thoughts of being bent over and fucked and filled suddenly came back with a vengeance and all he could think about was how good it would feel to let Devon take his first spin with his new cock on his tight pert little ass.

Clark beat him to it, however, still **** for his own fill of some more of that delicious cum. He had crawled over from besides Adam and lowered his lips towards Devon's monstrous beautiful veiny shaft and its purple bulbous head. He kept perfect eye-contact with Devon until the black stud nodded gently and guided Clark's mouth to his massive cock head. There was nothing gentle about the way he used the boy's throat though, and soon enough the changes that had made his throat such a perfect cock-sleeve took hold of Clark, and before long his new and beautiful swollen balls were slapping against Clark's chin. Devon looked over at Adam, who was biting his lip and moaning like a slut, so jealous that he didn't get to taste that meat first. His cock was something but Devon's just had a power and a magnificence that was indescribable to Adam. He was Devon's and Devon knew it.

Devon pulled Clark's head off his shaft with one huge pull, the scrawny boy's throat gripping it like a face-pussy that desperately didn't want to let go.

'There's a good boy,' Devon told him. 'But now I think there's a slut here who needs to get broken in proper fucking hard.' He shot off a spurt or two of cum into Clark's mouth before pushing him aside to undergo his own life-changing transformation. Adam took one more amorous look at Devon's incredible cock before bending over and letting Devon line-up. The stud spanked Adam so hard he whimpered, before taking a firm grasp on his ass and lining up his cock with the previously dominant boy's tight hole. Devon pushed and Adam screamed.
