Unfortunately, or fortunately for Riku, Sora really was hanging on the mood swings. Anything could happen between now and then to completely wreck his mood and desire to even be close to Riku too much.
"Oh, exclusive. I feel really special." Well, he did consider himself a little special anyway. He was Riku's only boyfriend, and Riku was awesome.
Sora paused for a while. He swore he heard it was bad for you to do it in a hot tub, but that might just be actual sex, which he was sure there wasn't going to be any of. "Wouldn't we get in trouble?" Or drown on accident? "I want to make out with you in the hot tub," he said, just putting that out there. "Anything else can happen elsewhere." He nodded, as though he had made an important decision.
And he didn't think it even remotely awkward to be talking about their intimate life just like that. Cheeseburger!
