Mettaton X Papyrus

Overprotective Sans

Papyrus was on his date with mettaton and he had some spaghetti then mettaton decided to try some so he ordered some as well. Mettaton tried some of the spaghetti and he lit up like a light, papyrus looked at him " do you like it..? " he said. Mettaton smiled widely " I love it!!! " He shouted then chuckled and sat down. They both laughed and talked about each other and ate spaghetti. Little did they know sans was watching them from behind a plant and he glared at mettaton. ' be good to my little brother you robot '. Mettaton felt eyes on him then he spotted sans and smirked then put his hand on Papyrus's sort of hand and papyrus blushed. They both finished their dinner so they went back to Papyrus's place since sans stayed back and ate for a little while.

( later at Papyrus's place )

Mettaton layed papyrus down on his bed as he looked at mettaton straight in his robot eyes then mettaton rubbed the bones on his chest. He continued and grinded against the part of his bones where his dick would be if he had one, papyrus moaned a little then breathed heavily then with his robot tounge ,mettaton licked that part and papyrus gasped then moaned louder and jolted up then in the middle of it ,sans came in without knocking and papyrus knocked mettaton on the floor where sans wouldn't see then he blushed and covered up " hey bro I got you so--" sans blinked and dropped his plate " SANS i-its not wh-what it looks like! " mettaton got up then sans grabbed mettaton " I told you not to touch my brother or I'd kill you " papyrus shouted for sans to leave mettaton alone just as soon they kept battling then mettaton lost his arms " I'm sorry papyrus I should be going now.." Mettaton ran out of the house then sans smiled " and stay out.." Papyrus was so angry " SANS YOU KNEW I LIKED HIM WHY DID YOU DO THAT YOU KNOW WHAT?!?! IM MOVING OUT " sans gasped then watched papyrus as he grabbed his photos and broke them then packed his clothes up and left. Sans sat there. He started to cry.
