He was definitely surprised by the intensity of her kiss, but he liked it. He couldn't deny that he felt deeply and passionately for Riley, nor could he deny wanting to be more intimate with her and taking that kind of step. Lucas was very interested, so of course he just went with it for the moment. He even went so far as to turn toward her to wrap his arms around her waist.
After kissing pretty intensely for a little while, Lucas needed to take a breather and rested his forehead against hers. "Hey," he said softly. He honestly was all for whatever she wanted to do, but if she kept kissing him like that, it was going to be hard to hide how his body reacted to being this close to her.
"You alright?" This seemed a little more than usual so it was just how he was checking in with her.
