"So you're afraid that I won't go easy on you by... being more irresistible?" he wrinkles his nose a little at the strange bit of logic. "I can't say that I know what I'm doing that makes me that desirable, but you are stuck with me in your bed a few more days, so I guess you'll either have to learn some self-control, or be exhausted," it's pointed out very logically, but then he smirks, relaxed enough to joke,

"Unless I'm sleeping on the couch?"

It's a joke, but it costs him something to say it, because it's not outside of the realm of possibilities and his brain is still trying to remind him that this isn't the kind of thing that happens to people like him. Still, he's also pretty sure he's not sleeping on the couch.
