Castiel could have removed his shirt himself, but he was fairly certain that proper protocol was having Meg do it, instead. She'd done it for him already, before, when she placed the medicine for his cold on his chest, but this was different. Much different. It wasn't because he was ill, but because of something that had nothing to do with colds or her being his care taker. This was about the connection they were trying to forge between them, something deeper than what they already shared, that much Castiel was aware of. For him, that was what sex was about, because it required actual feelings involved and people didn't engage in that if they didn't care about the person they were otherwise involved with.
When his eyes swept over her as she leaned back against the pillows, the appreciation in his gaze wasn't simply for her physical beauty. There was that, yes, because he couldn't deny the attraction he had for her, the very attraction that his body acted upon at the sight before him. This time, she was aware of his gaze on her, it was something that she placed before him of her own will, not because he'd trespassed on her because he'd been seeking her out. He felt that momentary lump in his throat, not out of fear but because he was struck by what he saw. He didn't know that what he felt was actually love, that the word he'd been searching for to explain how he felt for her, it was love, but he knew he felt whatever that feeling happened to be, when he looked at her.
"I... yes." He answered her question, stammering a bit as he did so. "I like it... very much." A beat. "You're beautiful." It was honest, no frills. He didn't know how to truly wax poetic, not including when he attempted to read poetry to her before. He simply saw what he saw and put it into words.
There was a moment of pause, as he looked down at her, one hand currently cradling the side of her face, tracing along there for a moment, until his hand made its path along the slope of her neck shoulder. When he moved in to kiss her again, it was that soft, gentle kiss from before, more tender than when she pulled away to remove his shirt.
