A Bone to Pick With You

by Snowflake Obsidian

Papyrus and Mettaton have a secret relationship and the only monster who knows about it is Sans. Papyrus and Mettaton want Sans to keep it a secret because it would be bad publicity for Mettaton, which he does, at the expense of teasing and joking to make them both embarrassed. (NSFW)

"M..Mettaton! What are you doing here?" He lay sensually on the tv, somewhat disappointed he didn't have a rose in his mouth and a piano to lay on. "Who let you in... What are you doing here?" The silent robot inched away from the tv and sat up, legs crossed. He grinned maniacally and jumped off the TV onto the floor.

"Oh... Papy." Mettaton looked down from the tall skeleton's boots to his eyes.

"Uhh... Mettaton... You're looking at me funny- Well, who wouldn't look at me like that. Me, the great Papyrus!"

Mettaton smirked. "Mmm. That's what I like about you. Such self interest. I wonder..."

"Wonder..?"

"Yes, I wonder if I could direct your interest and attention to me. After all, I am the underground's most famous celebrity. And well, when I see you, I see myself. And do you know what I think about when I think of myself?" Papyrus jerked his scarf to try to air his cervical vertebrae. "I think to myself," Mettaton inched closer, "'what a sexy robot. How wonderful would it be to try to please a robot this good looking?"

Papyrus looked at the sexy robot, inching closer to his face every second. "Mettaton... I understand you'd like to be with the future royal guard, but I'm afraid I won't be of use for I, the Great Papyrus, have no skin or lips to kiss or please you with."

"However, my dear Papy, you have big, long, large teeth... Your sexy bones... I can just imagine how you could make my wires short circuit." Papyrus began to blush. "Well, my Papy, I can see how despite your lack of skin, you can manage to impress me. I do wonder what other surprises you have in store for me." With this, Papyrus began to show a little something. "Oohh Yesss... oh Papy you're so quiet."

"M-mettaton... I... Well... What is the appropriate response to this... umm... surprise visit?"

"Well," responded Mettaton while stroking his hair, "You could reciprocate what I'm proposing..."

Papyrus stared at Mettaton's lips and thought about how those metallic crevices could do to him. "Mettaton, I believe I'm not quite sure what you're insinuating. Perhaps a visual refresher could do me aid." Papyrus flirtily lifted his eyebrow to show Mettaton how he wanted to be treated.

"Ohh... So that is how you want to play..."
