The Mask, The Task, The Flask

The masked man asked for a task to be completed.
He asked for a flask; his supplies were depleted.
The masked man asked for a flask of sun tan lotion.
In the sun he wished to bask, as he sailed across the ocean.
The masked man basked as he sailed across the ocean.
Thanks to his flask filled with sun tan lotion.
The masked man reveled in his newly tanned body.
But pined for the tan lines that looked so shoddy.
He spread the lotion here and there, ne'er to miss a place;
But in the end his mask undid him, for he forgot his face.
