Ty walked down the street looking around at all of the people enjoying the nice weather. He grinned in sadistic glee. He could do any horrible thing to them he wanted. Anything.
A mother and daughter walked towards him. The mother looked to be in her late 30s the daughter looked to be about 11. The mother sported and impressive rack, but the daughter was only just starting to develop.
"Swap," Ty whispered to himself. The mother's shirt deflated as her daughter's suddenly filled to almost bursting.
The young girl's training bra had snapped off and was clearly visible through the tight fabric of her shirt, resting uselessly on the enormous and out-of-place breasts that now hung on her chest. Ty could see the middle age nipples through the shirt, looking dark and worn out. He could see cleavage poking out of the top, the flesh was freckled from years of sun and vein covered. These were a pair of saggy boobs well beyond their prime, and now they belonged to the young girl that had once fed on them. She looked so top heavy that she might fall over, and held her new endowments in her little hands to help balance the new weight. She groaned in pain.
The mother was a different story. She felt a strange lightness. A quick peek down her shirt gave her a view of a pair of pink nipples on two soft girlish mounds. She gasped in surprise, and then screamed in terror when she saw her daughter.
"Oblivious," Ty said. And the rest of the people on the street paid no attention to the panicking mother and crying daughter as they hurried away to who knows where for help.
A young boy walked by holding a balloon. Ty whispered, "Switch." The helium in the balloon deflated as the boy inflated with fat, until he was nearly as wide as he was tall, clothes bursting off of his body as he swelled.
"Oof," he said as he fell on his humongous ass. He tried to stand but couldn't. He started to cry, tears dribbling down his chubby cheeks to the folds of his many chins.
Ty walked around the round boy smiling. The boy paid him no attention.
A woman across the street with large breasts walked the opposite way down the street. Ty whispered, "Hop." The woman's lower half was replaced by the lower body of a kangaroo, which was clearly visible as her whole body was now naked. She nearly fell over but instinctively hopped forward her breasts bouncing wildly up and down, up and down.
A teenage couple walked towards Ty. The guy looked tall and athletic. The girl looked short and pretty. "Exchange," he whispered. The girl grew taller and more muscular while the guy grew shorter and prettier. They had exchanged genders. The former guy's clothes hung on her loosely as the former girl's clothes ripped at the seams under the strain his new athletic body had put on them. They looked like a pair of clumsy cross-dressers. They gaped at each other and started to loudly wonder in new voices about what had happened.
Ty walked passed them.
A more mature couple walked towards Ty next. Ty wished to read their minds. They were on a first date. "Jerk," Ty whispered.
The woman grew a foot taller all in her legs and stumbled a bit, while the man shrank into a 13-year-old boy, his clothes shrinking to fit him. He looked up at his towering date and then pulled out his pubescent dick and began furiously masturbating. They both looked shocked. "What?" he cried in a cracking voice. "I can't control my hand. It won't stop!" She stepped back, and her long legs became tangled. She tripped over her own foot, falling a long way onto her ass. "Oh, no! It's coming! No! I can't stop it!" her immature date cried as his body stiffened and he spurted out a small stream of semen onto her legs again and again. He groaned and gasped lewdly as his body shook from the orgasm. She screamed and stumbled to her feet, then stumbled down the street away from the boy, who had started to cry. "I'm sorry!"
The boy zipped himself up and started to walk off the other way, trying to escape the shame of that moment and hoping that no one else had noticed what he had done. Then, he spotted another attractive woman walking his way. Unconsciously, he unzipped his fly and started to masturbate again as he stared at her. "No, no, not again!" he cried, tears running down his cheeks. "I can't stop!"
The woman gasped and slapped the boy hard in the face. She walked passed him, but he kept jerking. "I'm sorry," he said between sobs. "I can't stop doing it." He sobbed. "I can't stop. Somebody help me," he moaned. No one came to help him.
Ty walked passed the boy and stopped at an intersection.
A mother and a baby in a stroller wheeled in Ty's direction as they crossed the street. When they reached Ty's side of the street, he whispered, "Age." The mother started to look more refreshed and attractive and then rapidly shrank as years fell off of her body. She flew through puberty backwards into childhood and ended up a baby sitting in a pile of grown up clothes. In the stroller, sat a naked woman, the new baby's daughter grown to an adult as the mother had shrank. Torn baby clothes were hanging from the stroller, which creaked and looked ready to collapse under the weight of her curvy adult body. "Mama?" she asked quizzically.
Ty walked by them turning the corner as the baby tried to extract herself from her formerly fitting clothes and stand on legs too underdeveloped to walk yet.
A family of four approached him on the next street: mother, father, sister, brother. They all held hands, mother and father in the middle, father holding brother's hand, mother holding sister's hand.
Little sister said, "I want a new teddy bear."
Older brother agreed, "Yeah, can I get a new ninja turtle, too?"
Mother said, "No more toys this week."
Older brother appealed to his father, "Dad, please?"
Father wisely supported mother, "You heard your mom. No more."
Ty whispered, "Toy."
Mother shrank and grew soft and fuzzy, while father shrank and grew green and hard. A moment later, daughter was surprised to be holding the arm of a new teddy bear in her hand where her mother's hand had been. Brother was shocked to be holding a new ninja turtle by the hand where his father's hand had been.
Brother: "Dad?"
Sister: "Mommy?"
Ty walked between the siblings as they stood in stunned silence, staring at their new toys.
He smiled and walked away not once looking back. "What a lovely day for a walk."
