How to pass the time

He looked all around. The trouble was everything was as he remembered it. Still he had to start somewhere as he only had 30 minutes. He took the unwishing stone and placed it on a number of things but none were correct. And so he started to hunt through the cupboards. At the back of one cupboard he found a gift wrapped present that had a Happy Birthday John tag on it.
"Much too obvious," he thought, but he decided to open it up anyway.
He carefully unwrapped the present. After all he might just be undressing Karyn. That thought made him quite hot. Inside was a box that had on it Climax Creator Multi Vibrator. He took it out and looked at it. Luckily someone had thought to have included some batteries and so he switched it on.
"This is too good an opportunity to waste" he thought. He dropped his trousers and put it on his penis. Moments later he was beginning to feel excited and he started to moan. Eventually he exploded in a load of cum. "Oh man that was great" he said out loud.
"Yes you certainly sounded excited" said a voice behind him. Then there was a lot of laughter as he tried to cover himself up.
"I was watching the whole time, after all I was the clock on the wall. I see you like my birthday present for you" Said Karyn. I thought that we were supposed to be playing hide & seek. Since you didn't find me, I guess it is my turn again." So with the stones in hand she raced off upstairs.
