Mettaton's secret dance.

Sans was walking by Mettaton's room when he heard some...interesting sounds ,"Oh yes, work it baby!" Mettaton had yelled ,"Mmm, so good!" Sans heard once more, and he couldn't help but take a good peek, even if it'll probably scar him for life.

Sans didn't know what to expect, actually he did, but he didn't see what he expected, instead, he saw Mettaton dancing around in hot pink bra and panties. Once he did see this...interesting sight, he burst out laughing, which caught Mettaton off guard.

"YOU CREEP! DON'T LOOK INTO OTHER PEOPLE'S ROOMS WHILE THEY'RE...EXERCISING!" Mettaton said and he had slammed the door on him.
