Xavair is your swimming instructor.

You're standing at the top of the diving board while Xavair is staring up at you from the pool "Come on," He laughed at your nervousness,"scared?"

You glared down at him, And jump down and You looked down and realized... your underwear was.. gone.

You immediately looked around and saw it floating in the distance

"Can you.. get my.. thing.. over there?"You awkwardly said,

He just grinned. And very slowly, sunk into the water, disappearing from your sight.
