Body swapping

As Jessica recited the incantation, "Mutatio corporum aute irure, dolor et reprehenderit in voluptate velit esse…" a surge of energy rippled through the room, wrapping around them like a gentle embrace. Colors danced in the air, and a soft hum filled their ears, lulling them into a state of serene drowsiness.

With a final, gentle exhale, they succumbed to the spell's magic, their consciousness slipping away.

When they awoke, the world around them felt different. James blinked, trying to make sense of his surroundings. He looked down and realized he was holding the Arcanum Grimoire in his hands. 'Why do I have a long pink nails?' Thought James as he dropped a book on the ground.

"Jessica?" he called out, his voice tinged with uncertainty, sounding exactly like his step-sister. There was a pause, and then he heard her voice, filled with equal confusion, reply from across the room.

They had swapped bodies. He was looking over the bed as he saw his own body moving on its own. "Yes! It really worked!" Jessica, now occupying his body, jumped off the bed, and her masculine legs hit the hard floor. "Woah, bro! You are much taller than I do." She tried to hold her ground as she balanced in her new body.

"And it feels, quiet off not feeling a bounciness as I do this." She jumps up and focuses on her chest, which now holds abbs instead of her regular B-cup tits.

James' eyes fall down where he spots what Jessica normally sees - a large cleavage to her modest breasts. Two mounts, supported by a black bra, gently moved as he stood up. "Woah, it feels weird, Jess. Why did you do this? Swapping our bodies?" James also tried to hold a balance as a new weight on his chest sent him forward.

She comes closer, her figure is now a half-head taller than her former body. She looks down into her own blue eyes and says to her stepbrother. "Hey, James. Don't be a pussy, literally…" She jokes as she pokes her pussy mounds through the fabric of leggings. James moans with a high-pitched tone as he experiences a jolt of pleasure in parts that he never should have. His womanhood twitches and he steps back, trying to process the emotions that go through him.

"What are you doing, sis!" His anger looks cute on her gentle face and she bursts into laughter.

"Huh? Toying with you." She says as she grabs a bulge forming in her pants. "I've always wondered how it feels to have a dick." She grabs the top part of her pants, pulling it away as she looks at his junk. "And who would say, you have such a cute dick, bro."

"Hey, cut it out!" James moves to put his sister in place, his tits bouncing in a way unknown to him as he pulls her hands away from his crotch.

"Don't tell me, you never wanted to know how it feels to have a pussy…" She looks down on her brother, now occupying her lovely body. James just twitches, thinking about what she said.

"Maybe… But that's not what we should do!" James argues back, but he also wonders what it's like to be a girl, how fair sex is when it's full of pleasure. But his moral is higher than his sister's so he tries to hold his thoughts back, but Jessica sees him hesitating.

"Just give it a try. If you don't like it, we can go back to our original bodies." Jessica's words are tempting, leaving her stepbrother to decide his next move.
