Barcus having to make sure Satchel is distracted does mean that Bel has considered matters and decided he can wait the few seconds it takes to walk towards Barcus's bedroom. Feeling Barcus's arms around his waist, and hearing those words does cause Bel's pulse to pick up. "I'd say those are dangerous words, except, at the moment, I'm also all yours."

Well, that and while 'I am going to get laid' is a thought in Bel's head, most of the rest are along the lines of 'where does Barcus like to be touched' and 'I wonder what he sounds like in the throes of passion'. He bends to kiss Barcus's forehead while walking them towards the bedroom door.
