Wufei froze, drawing in a sharp breath as the words sank through the haze of pleasure and actually registered in his mind. He shuddered, eyes wide as they met Duo's. "Y-you what?" he whispered, but before Duo could actually answer, he lifted his hand to cover the other man's mouth.

He knew damn well Duo wouldn't say the words lightly, or in the heat of a moment. He knew they were real, and it terrified him. He swallowed hard, scraped his brain for the right words, before settling simply on the truth; "That's the only thing I'm afraid of. I don't want to hurt you." He knows he's terrible at this, no matter how strong his feelings for his fellow pilot are.
