Martin's ears actually look like they might be painful, they're so red. But honestly, there's a lot of pleasure mixed up in that embarrassment. Yeah, he's not used to being in this situation, he's not used to people fancying him and especially not used to people who follow through on that fancying, but he isn't entirely inexperienced, and he's pleased that (at least on the face of it) she had as much fun as he did.

Martin sinks into the kiss easily. He does try to keep in the back of his mind that he's holding a mug of tea, but that sort of thing doesn't matter as much as she does.

His expression is a little dazed coming out of the kiss, and then she says thank you, and it's morning and he's not even entirely sure why she's saying it, but there's really nothing left for it but to grin at her, squished morning face and bed hair and all.

Kaidy is definitely not wrong in her suspicions.

He ducks his head, still grinning, and takes another swig of tea. He thinks as he does so.
