OK, all gutterite aside, I forgot to provide some examples to Smitten for that first night in the cottage.
I sort of noticed when the sky began to lighten...“Do you miss it?”...It wasn’t the first time we’d spoken, but we weren’t exactly keeping up a conversation, either.
This is hours later, and Bella is making it clear there hadn't been any real pillow talk up to that point, which suggests that there hasn't been any breaks in the action up to that point. Subsequent text indicates that they may have been taking a mini-break at that very moment, but that is inconclusive. If they were taking a break, it didn't last more than one or two minutes.
Finally, at sunrise:
"How long does this go on? I mean, Carlisle and Esme, Em and Rose, Alice and Jasper—they don’t spend all day locked in their rooms. They’re out in public, fully clothed, all the time. Does this… craving ever let up?” I twisted myself closer into him—quite an accomplishment, actually—to make it clear what I was talking about.
We laughed together, and the motion of our laughter did interesting things to the way our bodies were connected, effectively ending that conversation.
Assuming that this is an "after" conversation, SM's text suggests that Edward's engines were on idle, but not shut down. This is my interpretation only, but I think SM is getting about as explicit as she can without getting graphic.
"It will take an amazing amount of control,” she mused. “More even than Carlisle has. He may be just strong enough…the only thing he’s not strong enough to do is stay away from her. That’s a lost cause.”
