In The Vaulting Lesson

Arriving at Juliette's house, Laura - or rather, Lasse, inside of Lauras skin - greeted Juliette warmly. They had arranged to meet up before Juliette's vaulting lesson. Lasse had mastered the art of maintaining their separate lives flawlessly, his ability to keep up appearances as both girls becoming second nature.

They moved to Juliette's room, where they spent an intimate hour together. Lasse in Laura's body engaged with Juliette, exploring the new sensations and experiences of this shared intimacy. After the intimacy, they lay together, quiet, the soft rise and fall of their chests the only sound in the room.

It was time to switch. Lasse, still inside Laura, got up and looked at Juliette's still form. He reached for the 'pen' device, aiming it towards Juliette, and pressed the button. The transformation was quick - Juliette's body collapsed into the familiar skin suit.

Lasse sat back down next to Juliette's deflated form, contemplating his next steps. He carefully removed Laura's skin, like peeling off a second layer, leaving it deflated next to him. The transition back to his original body, Lasse, was abrupt and cold. He missed the warmth of Laura's body, the feeling of her skin against his.

But there was no time to dwell on it. He was on a schedule. He picked up Juliette's skinsuit, feeling its weight in his hands. The fabric was smooth and cool, just like he remembered. There was a seam running down her back, just as there had been with Laura. He slowly began to step into Juliette's skin.

His feet slid in first, stepping into a void that felt like nothingness yet at the same time like he was enveloped in a warm cocoon. Then came his legs, hips, and torso, each part slipping into Juliette's form like a glove. He closed the seam behind him, feeling a small shiver as the suit sealed itself along his spine.

His heart pounded in his chest as he looked down at his new form, his hands running down Juliette's flat stomach and curving hips. He cupped Juliette's breasts, feeling their weight in his hands. It was a strange feeling, being in a different body again. But he was used to it by now.

As Juliette, he moved around the room, testing out her form. Each step felt like an echo of Juliette's own movements, each gesture a mirror of her own. It was uncanny, but he was comfortable in her skin now. With one last glance at Laura's deflated form, he left the room before coming back a minute later to inflate Laura, she had to pick "her" up from "her" lesson later.

An hour later, he was at the vaulting lesson, perfectly playing the role of Juliette. His movements were graceful and fluid, the result of Juliette's years of training. As he twisted and turned in the air, he felt a surge of exhilaration. He was Juliette now, and for the next few hours, he would live as her, undetected and perfectly blended in. He looked forward to it. It was a thrilling, secret existence that he alone was privy to. And for now, he wouldn't have it any other way.
