Flash back earlier in the day

It's a beautiful, sunny day, Tracy is walking quietly in the park with music in her ears.

Her graceful walk, with her slender legs perfectly shaped in mini shorts, attracts the attention of all the people she passes. Men and women turn around as they pass her, observing her perfect body, topped by an angelic face. Her t-shirt lets guess her flat belly, drawn by a firm 6 pack.

Completely distracted by her music Tracy doesn't realize that she is heading into a dead end and comes face to face with a homeless man, tripping over him.

Tracy: "Ouch! What are you doing here? Lying in the street like a piece of trash? Oh my God, you stink! Get your filthy hands off me!" Tracy said with a disgusted look as she got up.

Joe: "You're the one who fell on me! You insolent little brat!"

Tracy: "What? How dare you talk to me?"

Joe: "I can talk to you any way I want, kid! Besides, you should respect people more! You don't know what could happen to you, one day you could be in my place! Joe said with a sly smile that made Tracy take a step back.

Tracy: "What do you mean?" She asked in a panic.

Joe: "Oh, but you'll understand soon enough! With these words Joe grabbed a rock from his pocket and grabbed Tracy by the hand, preventing her from leaving.

Tracy: "Let go of me you old pervert!

Joe: "Soon you'll regret your words!"

Tracy: "Are you going to kill me?

Joe: "Oh no, but I won't tell you more, you'll see!" Joe says, starting to laugh.

Joe having just finished his sentence, Tracy notices something strange, his skin seems to lighten up. Just like his hair, from a dark black it becomes brown, then chestnut, then blond. Joe seems to be getting younger before her eyes.

Tracy: "What is going on? Your hair, your skin! It's changing! I don't feel well, I feel nauseous...". Says Tracy in a panic.

Joe: "It's normal my dear, it's justice! ahah! How nice it is, I feel the youth coming back in me! My hands! Look at my hands little one! "Joe shouted to Tracy.

Joe's hands started to get younger, the wrinkles disappeared, his fingers got longer and thinner, the nails slowly got covered with a shiny black varnish.

Joe: "Oh yes! Thank you! I'm feeling better and better!"

The changes start to become more and more obvious! Joe's chest starts to swell, two nice firm and young breasts grow rapidly stretching her patched t-shirt. His waist begins to slim, and he starts to feel Tracy's strength joining him. His big, fat belly shrinks to make room for 6 abs and a perfect stomach.

Joe: "It's almost over" Joe shouted, feeling his voice slowly change, becoming higher pitched until it sounded like Tracy's voice.

Joe: "Even my new voice is beautiful!" he exclaimed.

Once Joe's body was completely changed into Tracy's, his clothes started to tighten, and finally they were replaced by Tracy's.

Tracy on her side underwent all the opposite changes, she felt weaker and weaker, she could not breathe anymore, probably because of Joe's old lungs, damaged by 30 years of smoking.

Tracy: "What's happening to me?" Tracy says, crying, in Joe's voice.

Tracy, lying on the ground, sees her reflection in a window.

Tracy: "AAAHHHHHH!!!" Tracy screams, and passes out on the floor.

Joe: "Perfect, this beauty is mine now! And no need to run away from her, she fainted by herself! Too bad, I would have liked to scream at **** while shouting at the ****, I could have got rid of her for good! Too bad, at least it was quick!" Joe says as he slowly strokes his entire body, by the time he gets to her breasts he closes his eyes and moans softly.

He then directs his hand to her vagina and slides a finger in, his lips so wet that there is no resistance.

Joe: "Girl, are you still a virgin?" He says with his finger still in her pussy.

Joe:" I wonder if you were saving yourself for someone? ahaha"

Joe then bends down over Tracy and whispers in her ear.

Joe: "Sorry little one, I didn't want to use that thing, but you **** me to! From now on you'll have time to think about your words! Aha! While I'm enjoying your youth! That is, if you manage to survive long enough on the street!

Joe gets up, and pulls his finger out of her vagina, he then directs it to her mouth and sucks it languidly.

Joe: "Mmmhh, what a delicious taste!"
