My trainer's fit body (Patreon)

“How long are you allowed to have her body?” Jack asked while he watched Emily from the other side of the room. “The contract did say that you could do whatever?”

“That was in the contract,” she told him with her trainer’s seductive voice. “It’s a full month - we both signed clauses that basically transfer ownership to each other temporarily. She can do what she wants in my body, while I can do what I want in her body.” She winked at him. “You want me to keep her body a little longer too, don’t you?”

He nodded as she giggled. Emily leaned in close to the nearby mirror right after, gazing lovingly at Kenzie's cute face. She looked at the personal trainer's pretty smile from the side, admiring the contours of her chin and the way her lips curled. Emily was given the go-ahead to spend the next month lounging around the condo while Kenzie worked out regularly in her slightly heavier body. They agreed to temporarily swap bodies at their local body swap clinic and signed al the necessary paperwork.

At first, Emily felt incredibly uncomfortable. But after three days, she mustered the nerve to take off her clothes and explore her body.  Her trainer's slender body felt flexible and elegant as she prepared for an exciting night out. Pulling on Kenzie’s sexily tight white dress, she glanced at herself in the mirror and finally decided to enjoy herself while Kenzie exercised in her body. 

She ran her fingers through her blonde hair and smiled. "I hope I look just as good as her when she's done," she whispered. Emily put on the last of Kenzie’s makeup and turned to her boyfriend. The look she got from him radiated with approval as she took his hand. She couldn’t wait to flaunt her trainer’s body in front of her boyfriend’s friends.
