The third wish ended up being used for something physical...as Sarah called it.
It was the first time Sarah went down on anyone, and Hajin had no idea what turned him on more: the fact that it was her first time, or how hard she tried despite not being good at it. She couldn't take it deep because of her bad gag reflex, but Hajin was already on cloud nine from seeing her red face and teary eyes. The fact that she still swallowed the cum just made him...ecstatic.
It was as vanilla as it got, but for a princess who only lost her virginity a few months ago, it was something. Hajin also didn't like the thought of using toys as if they were his substitute, so they didn't use that. As for the other, raunchier stuff...
Well, they still had many birthdays in the future.
