Y/n pov

You were wearing a collor around youre neck it was Black since sans wanted it to be black and a red leach. "Come on pet." you were scared for him he hurted you sometimes and it hurted so much you were treated like a dog. You had Almost no food no drinks or warmth and in some cases you got whipped but That was rare. "yes my l-lord..." you were Almost crying you didnt ask for this. "what was That?" "nothing.." "fine.." he had a worried tone but he tried to hide it. You were thrown in youre cage again and when he walked away you started crying. You grabbed a sharp piece of metal you got from youre collar since they have spikes on them. You cutted youre self with the spike but at That moment sans came in. "i forgot some-" his eyesockets widend. "Y/N WHAT ARE YOU DOING!?" you were so dead so fucking dead. "l-lord..?" he pulled you out the cage and pulled the spike away from youre hand. "Y/N!" you started sobbing again. "y/n..." "im sorry lord.... I Will clean up the mess..." you wanted to walk back to the cage to clean up but he grabbed youre wrist making you hiss in pain. "S-sorry y/n are you okay?.."  "lord Just let me clean.." he shook his head. "no y/n Why did you do this..?" "because of all the pain im expierencing from you... The way you Hurt me....not only physical but also mental...." he pulled you into a tight Hugging making you freeze but you hugged back. "y/n im so sorry i Just wanted you to be a bit stronger.." you nodded. "i know im weak my lord...." "no y/n youre not youre strong but please stop cutting and stop calling me lord okay..?" "okay lo- i mean sans.." he sighed. "im so sorry im so fucked up I-i love you y/n.." he was blushing it was pretty cute. "i love you to sans.." he smiles at you
