Kel was too scared to breathe; Sabine was right in front of her.

"Practice on me," Sabine repeated.

"But…I'll go right through you."

"So? It's better than nothing. And I am technically nothing, so you're not even cheating on your sweetheart by kissing me."

"He's not my sweetheart."

"Not yet. So hurry up and do your practice."

Kel gulped and shut her eyes. She was just about to lean forwards to where Sabine was when she felt a light touch, almost like a breeze of air, on her lips. Her eyes flew open. "I felt that," she said.

Sabine was staring at her, confused. "Me too." She inhaled deeply. "Do it again."

Cautiously, Kel leaned forwards, her eyes staying open until the last moment this time. No sooner had she felt the same touch on her lips than she heard a loud thud. She opened her eyes to find Sabine standing on the floor next to her, and she gasped. "You're solid."
