IT'S A TRAP!

As the young scientist finishes his cup, a strange tingling begins to wash through out his body. Starting in his stomach and radianting outward. As the tingling grows warm, he nearly drops his cup as he spins on his stool to look at his assisstant, who now has an evil smile as a previously hidden bump begins to grow in her skirt.

"D-dorothy? Why?" He said as his heart began to race. His body was nearly on fire now. "Because this is the next step in the evolution of humanity! Two sexes have gotten humans as far as it can, and now we, the futas, were created to be the ultimate penical of human ability," she said in an elaborate manner as she watched the scientist fall to the floor as he body began to change.

His face grew softer and feminine, as his hips limbs and torso grew more womanly. Within 10 minutes, the newest futa on planet Earth sat on her knees, panting as she gropped her new chest and her cock bulged and strained at her now to tight pants.
