"Here it goes..." Coal tips the vial nearly upside down, and forces its contents down his throat. The taste bitter and acrid, but he manages to hold back throwing up.
"Master, are you ok? I can get a bucket for you if you'd like?"
"No, Xan, I think i'm ok..." Many minutes pass, and Coal has almost given up that anything will happen, but he begins to feel lightheaded. Then an intense warmth settles in his genitals, and he feels heat surging through his balls and cock.
Gripping himself through his pants, he can feel his little nuts expanding in his hand. Growing fat and heavy. They become almost too big to hold in one palm, and Coal decides he needs to take a look.
Pulling down his pands and boxers, Coal sees his swollen balls growning before his eyes. His skin gives only a little, making his nutsack look like an inflating balloon. Soon, heavy veins can be seen running under the skin, and pulsating with sensual power. His now stiff dick begins to lengthen, and large veins begin to twist and branch out all over its added girth. Xan is even frightened by the transformation and takes a step back.
At just over 25" Coals dick stops growing. His meaty balls, however, grow along with his lust. Coal mind begins to be filled with thoughts of the huge dick of his spewing. Being pushed into soft warm places. Fondled by sensual hands. Soon Coals mind races with only thoughts of sex.
A bead of cum begins to dribble down his enormous cock, he bends over to lick it. The sticky paste wets his tongue, and he swallows. It tastes like honey. Obsessed by the sensation of his own tongue lapping his plump cockhead, he goes down again, and slops up a trail of ooze that is now streaming out. His balls, now painfully bloated, are begging for release, and Coal is becoming more and more eager to oblige.
He wraps his lips around his dickhead just as he lets his first volley of cum shoot into his mouth. The velvety sweet jizz quickly fillsthe space, and Coal has to gulp down cup fulls so none will be wasted. His balls continue to expand.
