Greg moved over Theo's mouth, and now that Theo stirred and responded, he felt himself match the growing need that seemed to pour forth from Theo. Greg's lips parted and his tongue traced Theo's lips and touched the interior of Theo's mouth gently, stroking his teeth and tongue. His kiss was moving into snogging, deep satisfying snogging that would probably leave Greg frustrated as hell but he didn't much care. What he cared about was that Theo seemed to be alive in his arms, very much wanting the kisses he was giving him.
Greg kept rocking with him, and would have normally let his hands wander but he wasn't an utter idiot. He kept up the snogging though, his hand moving up to Theo's neck and into his hair as he kissed him, sucking on his mouth with want and desire.
