Assertive? Submissive?

Lucas was completely immersed in his thoughts that when warm hands wrapped around him, Jen could feel his body shake from surprise. Jen rested her cheek against the middle of his back and wrapped her hands tighter around him as if trying to warm his cooled body.

"I thought you were sleeping," Lucas said after getting over his surprise.

"I was, but you weren't around and I couldn't sleep anymore," Jen said her voice thick with sleep. She yawned and Lucas could feel her warm breath blow against his back.

Lucas kept his gaze focussed on the night lights of City X. After talking to his mother he wasn't really sleepy anymore. He held one of Jen's hands that were around his waist with one of his own hands.

"Let's go to bed" Lucas suggested when he felt Jen's weight become more pronounced against his back.
