"Hold me," said Jon, and Adam did. They didn't repeat anything more than fondle each other's private parts and kiss a little, but Jon knew that Joseph and Jeff were off doing their own thing--and this time Jeff wouldn't chicken out.
Jon had wondered if he'd notice when the trip ended. Of course, noticing was easy. For one thing, everyone had returned to exactly the time and place they had started, which meant that he and Adam were separated by several yards rather than in each other's arms.
The other three--Jeff, Joseph, and Adam--were also looking very confused. They didn't know about the wishes (least of all about Jon's strange ability to make the wishes silently), so as far as they were concerned, they had appeared on an island for no reason whatsoever, had sex, and reappeared without any time having passed. Jeff would be even more confused, having gotten a pussy for those two hours.
Jon could immediately end their confusion by making them think it was just a dream, but was there anything better to do? He certainly couldn't just leave things as they are and have the boys tell people what had happened to them.
