Pulling your balls inside yourself you muster the powers of strength and stamina to deposit into Charlie. "Are you ready to join the gods?" you ask, Charlie eating away, "3...2...1..."
Boom! You feel your seed erupt and enter into Charlie. He's so lost in his own duties he barely notices until the pure power ejaculation nearly knocks him back. You hold his head into place as you bestow him with the powers of strength and attractiveness. You don't give him the supernatural power you and Graham hold, but prepare Charlie for the transformation into a beast.
You toss him back as he lands on the floor, grabbing his stomach as he regains awareness of his surroundings and feels something very different beginning to occur. "What's happening to me?" he asks, a bit in fear but also in excitement as your seed integrates into his body.
Looking down Charlie sees himself changing. Only in his black swim trunks, Charlie notices hair growing on his chest and down to his abs as they contort into a tight eight-pack. The muscle mass moves over his arms, up through his neck and down to his hips and quads as they pump up. Charlie begins laughing as he casually slips off his trunks and stands, admiring his growing body in all its naked glory. His dark hair covers his quads as they bulk and climb up and over his ass. He grabs his package as it too grows. Stretching himself, he relishes in the moment of growth as it slows and the new super Charlie stands in all his muscular glory.
"Dude," he tells you between breaths, "this is incredible." He looks up and smiles. "Let's have some fun!" he says.
