"Yeah, I've gone and become self-indulgent over four and a half months of Milliways with access to money and appear to be in the mood for cake."
"You're so serious about it," laughs Bell. And she kisses a tiny little kiss right on the side of Sherlock's neck where her face happens to be.
"Hmm. I do not require cake urgently." Bell makes no move to let Sherlock go.
"There is some waiting involved in the last stage of the cake process," Sherlock observes.
"Okay." One more itty-bitty neck-kiss and Bell lets her go, smiling.
"You're blushing, that's adorable," says Bell, clapping her hands over her mouth.
"What kind of cake do I get?" Bell asks, getting up to follow Sherlock into the kitchen.
"There are many options," says Sherlock. "What are your opinions on the relative merits of chocolate and lemon?"
"Chocolate is better," says Bell contently, sitting at the kitchen table.
"Mmm." Bell inhales the scent of nascent cake. "You are good to have around."
"So good," agrees Bell. And when it goes in the oven, she says, "This must be the waiting period I've heard so much about!" and she trots sofaward.
Bell wonders what will happen if Tony is lured upstairs by the smell of cake and spots them. Probably he will go awwww.
