Crossmare [one shots]

Teachers pet

The moon shined through the windows as the only noise that filled the cold and silent halls, was the sound of footsteps that echoed through the halls. A certain monochrome skeleton was walking around the halls of his Teacher's house.

He was training to be a thief like his teacher, he had grown interested in it ever since the other found him. Nightmare, that was the name of his teacher. When Cross was still a kid, he met Nightmare who was two years older than him. He didn't have a place to go and Nightmare gave him one, he basically grew up with the other but the taller was more experienced in stealing and Cross wanted to learn too.

Though some kids in town would always beat up and bully Cross for how different Cross looked calling him ugly and weird. Though Nightmare would always come and beat them up and patch up Cross. But Cross didn't want to be protected forever, he wanted to be strong too and defend himself and Nightmare. So Cross trained hard he would fail but didn't give up, sometimes he would train for day's straight without eating and Nightmare would scold him for not taking care of himself and soon Cross limited himself while the taller would keep an eye on him. Soon Cross was strong enough to beat the royal guards and everyone in town. He was the strongest in town, but not as strong as Nightmare yet Cross didn't mind. And now here they are, adults by now and the smaller training to be a thief.

Cross stopped as he reached his destination as it was Nightmare's room. He knocked on the door and waited before he heard a muffled 'come in' and he took a hold of the door knob and opened it to reveal the other looking out the window to stare up at the moon. His tentacles flicked and swayed before one stretched out towards Cross, making the other raise his hand as his fingers coiled around the tentacle gently making Nightmare hum in satisfaction.

Some times they did that. It was Nightmare's way of showing affection to the smaller when he was far from the other, both of them enjoyed it so it was fine. Soon the tentacle tugged on Cross' hand, gesturing he should move towards the other. He did and walked over to Nightmare making the taller turn around to look at Cross. He pets his head. "How are you feeling? Did you sleep well?" He asked calmly as he scanned Cross' face for any sign of distress or discomfort as his hand slid to cup his cheek.

Cross nuzzled his hand and hummed as his cheeks heated up slightly. "..Yeah...." He said his voice so soft yet still being able to be heard by the other. He gave a satisfied hum and rubbed his cheek before he pulled his hand away which made Cross kinda sad but it didn't show. "Let's begin our training then" he said as he started to let Cross sit on a table and started to explain stuff to him and teaching him stuff and even making him try and steal something from him.

As Nightmare began to explain something Cross couldn't help himself but stare at Nightmare's face that everything the other was saying was just a muffled buzz to him by now. Cross admired Nightmare's features from his beautiful cyan eyelight to his- in Cross' opinion- hot lips as it moved but he couldn't hear the words coming out.

Oh what he would give to kiss those lips as their faces collide while Nightmare pins him to his desk then-

"Cross!"

Cross jolted and snapped out of his trance as he looked at the taller as he was raising a brow and frowning making Cross gulp the lump in his throat."Y-Yes?" He cursed himself mentally for stuttering as he stared at the other. "Are you even paying attention?"

"Yes!"

"You we're daydreaming-"

"No I wasn't!"

"You have drool on your chin-"

Cross blinked and wiped his chin quickly as his cheeks heated up a bit, making Nightmare sigh. "You've been more distracted these days....is there something wrong?" Nightmare asked softly, genuinely concerned for the smaller skeleton as he reached out and cupped his cheek gently to make him face him. "What has gotten you so distracted?"

Cross stared at Nightmare's eyes and blushed softly at the question as he felt his heart beat faster, though this time this emotion did not go unnoticed by Nightmare. The taller felt the smaller's soul flutter as he felt that disgusting feeling.

Love...

Nightmare frowned at the feeling. He's never felt love from anyone other than Cross and his brother though he loves Cross' love more than ever and finding out Cross' is feeling love towards someone else made his blood boil and stomach turn. Cross was only allowed to love him as selfish as that sounds, he hated the thought of someone taking Cross away from him.

He slammed his hands on the desk as he stood up, making Cross flinch in the process as he looked up at the other. Soon Nightmare trapped Cross to pin him against the table as his eye narrowed as he stared at Cross, his tentacles twitching and thrashing slightly. "Who is it?"

"W-Who is what?"

"DON'T PLAY DUMB WITH ME!!"

Cross flinched as Nightmare raised his voice at him. It was the first time he's ever done that and it scared Cross to his core. He started to shake violently as he tried to escape but Nightmare didn't let him. "ANSWER ME CROSS!!"

"I-I don't-"

"STOP LYING AND JUST SPIT IT OU-"

"I-I don't know!" Cross choked out as he felt tears start to build in his eye sockets, threatening to fall. "I-I don't know what your t-talking about! I-Im sorry!!" Cross' finally broke as his warm tears started to fall down his cheeks, he moved his hands to cover his face as he sobbed quietly in his hands as he shook violently. Cross was a strong person who rarely cried, the last time Nightmare saw him cry is when he found him for the first time.

Nightmare felt his soul drop as he stared at Cross, the person he cared about more then anything, crying.

Because of him....

Nightmare gently wrapped his arms around Cross as his tentacles wrapped around him too, making Cross flinch. "I..... I'm sorry Cross...I didn't mean to upset you...." The taller said softly as he rubs Cross' back gently. Cross stiffened but after a few minutes relaxed as he hugged him back, nuzzling his shoulder as he would release soft hiccups. Nightmare had already forgotten why he was so mad. He kissed Cross' head as he held him close to him.

Nightmare soon sighed. "I think that's all for today....you should rest...." He said softly and unwrapped his tentacles and was about to let go when Cross' grip tightened as he shook his head. He didn't want Nightmare to let go. The taller hummed and picked Cross up and teleported to his room as he went into the smaller's bed as he had Cross beside him. Cross cuddled him as he nuzzled his chest making Nightmare sigh in content as he wrapped his arms around Cross.

Even though Cross was an adult and was very strong, he still was soft and was still that scared little kid he met in the woods no matter how hard he tries to act cold and stoic. Nightmare can see right through him.

Cross yawned softly and felt drowsy from crying so much, he was half asleep. He heard Nightmare talking but couldn't make out the words so he just answered with a small 'ok and good night' before even realizing it he leaned in and gave Nightmare a soft peck on the lips before nuzzling the taller's chest as he soon drifted off to sleep.

Nightmare blinked and felt his cheeks heat up slightly. Before he just smiled softly and kissed Cross' head.

"Goodnight...my dear, Cross"
