Are You Coming In? ThranduilxReader

Thranduil decides to bathe in one of the glittering pools of his kingdom. You chance upon him in the process. As you try to escape he senses your presence. He could either pronounce some punishment or, he could treat you kindly. What will it be?
This is based off of some fan art a friend made. Credit to Marletta Williams Patterson, my friend, who made this fan art of Thranduil.
