Cheating 

—————————————————————————————————————

No ones POV : 

Blue and his lover , fell sans , were out for a stroll in blues Au . They were a happy couple , fell would give gifts and affection to his lover all the time .  Blue loved all the affection and attention he was given by fell . But what blue didn't know , is that fell was not as loyal as he seemed to be . Fell was secretly in a relationship with Sci , blues best friend . Fell didn't know what was to come by cheating on little blue ...........

Warrior sans POV : 

Damn fell , cheating on senpai with the ugly Sci sans . Warrior didn't mind the relationship blue had with fell until now . He may have been a yandere and jealous , but he was still a warrior with pride . If blue was happy with fell - so be it . But now , now warrior could dispose of the filthy abomination called fell . He never deserved to be blues lover . Only warrior sans would fit and be worthy to be blues boyfriend. 

I must protect my baby blue , oh yes - he needs protection from the filthy fell . And protection he shall get .  Warrior sans was on his way to fells home / with a bag of "toys" he would use on fell . And no , they weren't the kinky kind of toys - oh no no no no no , those would be for senpai . These type of toys were the ones that he used to torture those would hurt blue . And fell was next on the list.  He arrived at fells home , swiftly using his training to climb up to an open  window on the second floor - fells room . He saw fell sleeping with Sci . He decided that he would torture both of them for hurting his beloved .  He quickly gagged the two , restrained them and waited for the two to wake up .

{le amazing and convenient time skip because the author is lazyyyyyyy} 

Red and Sci wake up to a dark basement, chained up together . The basement door opens slowly to reveal warrior sans . Sci tried to scream / but couldn't due to the gag around his mouth ( area ? Idk skeleton anatomy is weirddddd) . Warrior sans soon took note of this and chuckled, and chuckled, and was fully psychotically laughing . Even red shook from his laughter, uneased by it . "You two know what you've done to blue , MY BLUE. I tried to give you a chance with him red , BUT YOU THREW THAT AWAY . YOU HURT BLUE , SO NOW .....hehe IM GONNA HURT YOU ." 

There screams of torture couldn't be heard that night, nor their pleas for mercy and forgiveness. The basement they were placed in was that of an old house , out in the woods , in an old abandoned au . The only thing one could hear if they were very close to the home , would be warriors psychotic laughter, from the pain of the two in front of him . 

{ Time skip brought to you by chocolate, that I took from cross . " wait WHAT " oops got to go hehe} 

Blue was quietly resting next to the waterfall in his au . He had just finished training with alphys and was resting here for now due to the calm vicinity the place possesses. Suddenly the small skeleton received a text . But what he saw made him loose control of his emotions . The text was sent to him by warrior , it was a pic of red banging Sci . Blue cried , he had thought there relationship was going well , what went wrong? Was he not good enough for red? He received another text from warrior , asking if he would like to be comforted. Blue immediately responded with yes , and warrior came right away to the water fall . 

That day blue had broken up with red , or so he thought - when it was warrior who responded to his break up text meant for red . He had killed red , but didn't want to scare his little blueberry . He rushed over and gave him hugs , and small rubs on his back - not wanting to go too far and make the little skeleton hate him . 

" T-thank you Warrior , I *hic* don't know what I've would have don't without *hic* you ." 

" Ah , don't worry little blueberry sans , I'm here to protect you ! Especially from evil beings such as red . You don't need that scum , all you need is me ." 

" Thanks warrior" 

And with that , blueberry went to sleep atop warrior . Warrior took this as an opportunity to take him to his home . He carefully picked him up , not wanting to hurt his princess, and took him through a portal . 

A few weeks after the incident, blue began to develop feelings for warrior sans, and they soon became a couple . They lived happily after that , but
