Luke tells Emma he wants to stop, feeling overwhelmed by the situation.

Luke's heart pounded in his chest as Emma's lips pressed against his, her body molding to his new curves. He could feel the heat of her touch, the softness of her lips, the sweetness of her breath. He kissed her back, his hands tangling in her hair, pulling her closer. He could feel her moans vibrating against his mouth, the sound sending a shiver of desire coursing through him.

But as their kiss deepened, Luke felt a growing sense of unease. This was wrong, taboo. She was his sister, his elder sister. He couldn't do this, no matter how much his body yearned for her touch.

He broke away, gasping for breath, his eyes searching hers. "Emma, stop," he whispered, his voice barely audible.

Emma looked at him, her eyes glazed with desire, her breath coming in ragged gasps. "What's wrong, Luke?" she asked, her voice husky with need.

Luke shook his head, his heart pounding wildly. "This... this is wrong, Emma. You're my sister," he said, his voice filled with turmoil.

Emma's eyes widened, the desire in them fading, replaced by a mix of shock and understanding. She pulled back, her hands trembling slightly as she ran them through her hair. "Oh god, Luke, I'm so sorry. I didn't... I didn't mean to..." she stammered, her voice trailing off.

Luke looked down at his body, at the breasts that were not his own, at the curves that belonged to his sister. He felt a wave of shame wash over him. What had he done? What had he become?

He quickly pulled off the bra, his body returning to its normal state. He grabbed his shirt, pulling it on, his hands shaking slightly. He couldn't look at Emma, couldn't face the shame and guilt that was reflected in her eyes.

"Luke, I'm so sorry," Emma said again, her voice barely a whisper. "I didn't mean for this to happen. I just... I got carried away."

Luke nodded, his eyes still fixed on the floor. "It's not your fault, Emma. It's mine. I should have known better. I should have stopped it before it went too far," he said, his voice filled with self-loathing.

Emma reached out, her hand gently touching his shoulder. "Luke, look at me," she said, her voice soft but firm.

Luke hesitantly looked up, his eyes meeting hers. He saw the concern in them, the love and understanding. He felt a lump form in his throat, the weight of his actions pressing down on him.

"Luke, this is a lot to take in. This power of yours, it's... it's overwhelming. But we can't let it control us. We can't let it change who we are," Emma said, her voice steady and reassuring.

Luke nodded, his eyes filling with tears. "You're right, Emma. I just... I don't know what to do. I don't know how to handle this," he admitted, his voice barely a whisper.

Emma smiled softly, her hand squeezing his shoulder. "We'll figure it out together, Luke. You're not alone in this. I'm here for you, no matter what," she said, her voice filled with determination.

Luke felt a wave of gratitude wash over him. He had made a mistake, had crossed a line he never should have. But Emma was right. He couldn't let this power control him. He couldn't let it change who he was. He had to find a way to navigate this new reality, to understand and control his power. And he knew, with Emma by his side, he could face whatever came his way.

{What does Luke do next?}

Option 1 - Luke asks Emma for her help in understanding and controlling his power.

Option 2 - Luke decides to keep his power a secret from the rest of the family for now.

Option 3 - Luke apologizes to Emma again, promising to be more careful in the future.
