A shiver ran through Sebastian's body when Lucius' lips parted his own, leaning into him, letting the hand on his back guide him. It was immediately obvious how much Lucius wanted him- or this. Perhaps just this, but Sebastian wasn't going to question that now. But the feeling of Lucius' cock pressed hard against his thigh was thrilling. He hummed, his tongue tentatively brushing against Lucius' lips as his hand moved down, down the strong muscles of Lucius' chest until he was pressing tentatively against his belly.
The hand on his neck, the physical presence of Lucius, perhaps Sebastian should have felt threatened, but he didn't. Far from it. He pushed himself up against Lucius' body, surprised at how much he really liked his own vulnerability.
