The cock quickly whipped out towards the finger, sensing the meal provided before it. As the ants sink into the slit they're quickly sucked up, even faster than before, almost as if it was learning how to eat things better and better with each feeding. About ten seconds later the pause came about again.. again repeating it's sudden growth, but as expected it grew twice as much, expanding in a wave from base to tip until it hung from his crotch, resting against his sac as it waits and drools nearly three inches long, now knowing it's going to get a steady supply of morsels. He begs and pleads, staring up at the lady. "Please don't.. I don't want to grow... not again..." He looks back down and away from his cock, not wanting to see the grotesque acts it's going to perform, feeling them is enough.
