Draco grinned when he saw Theo getting undress, but the slight hesitation made him pause. Slytherins were all about covering insecurities; that was what they did from the moment they were old enough to understand.
He was happy to kiss Theo until he felt his friend relax, and only then he pulled back. "Don't be a dolt, Theo," he said, staring at the other boy. "Never give that kind of opening to anyone unless you're willing to make good on it." He shivered at the idea of what Rabastan could do with an invitation like that.
He started kissing Theo's jaw, moving down to his chest, which he let his hands mover over his lover's body. "Learn what feels good and that's what you do," he said, looking up at his friend.
