AN: Before this begins I feel the need to remind people while I am writing same sex couples I am actually straight.
The light shone through the cracks of the curtains in the turning thirteen-year-old Mokuba's room. He was asleep until he heard a noise, his door open. He shifted in his bed when he heard the noise and shifted his hair which lazily drooped over one of his eyes. The figure was familiar, something about it reminded him of someone, and as the figure drew closer into the moonlight, it was abundantly clear who it was. Yugi.
The older male looked at Mokuba with sweet eyes smiling softly and caressing his cheek lovingly. Mokuba looked at him gulping as he felt a feeling between his legs, he was all too familiar with the feeling, his cheeks turned to a dark red color as he looked at him biting his lip. Mokuba was shocked when the older male pinned him down and the entirety of the older boy's structure changed, he grew taller, and more defined and held a more devious, sinister smirk rather than his prior look of sincerity and kindness. The older male leaned in and they locked lips.
Mokuba was kissing back and before long he was finding foreign fingers grazing along the inside of his thigh. Mokuba's eyes widened and felt as the dominant Yugi Moto ran his hands along his inner thigh and soon found his way to his zipper, a smirk rose on Pharaoh's face as Mokuba's member was released into the air. Mokuba then looked at the male as he reached towards his member.
"Yugi!" Mokuba jerked awake breathless as he looked around his room, surprised that he hadn't seen even a trace of the young Moto boy in his room. "Wh-What? It-It was a dream?" he looked down, a part of him felt disappointed, but a majority of him was glad. "W-What even was that dream? I-I'm straight . . . as straight as an arrow." He told himself. But his soiled sheets said otherwise.
The young Kaiba bit his lip, seeing the soiled sheets. "Oh no, how do I explain this to Seto?" Mokuba got up and quickly got his sheets together to wash later. He went into the bathroom with entirely new clothes and took a cold shower. The water felt nice and calming on his skin, normally he hated cold showers, he'd yell at his brother who will sometimes decide to try and be funny by turning off the hot water for a brief moment. But, normally Seto isn't funny.
Mokuba washed all over and flashes of the dream were coming back to him in very realistic thoughts. His cheeks went red and he touched the tile wall, his voice echoing in the large bathroom. "What is wrong with me?" he mumbled.
As the young Kaiba was drying himself off, he heard a familiar voice in the back of his mind, the sounds of Yugi's reassuring caring nature and then to counter that the carnal rough voice of Yami. Mokuba stared at the wall for a solid minute before realizing there was a voice calling his name.
"Mokuba! Get out of the shower you're coming with me!" Seto said in a demanding, yet brotherly tone.
"Be right out, Seto!" Mokuba called out, his voice barely overpowering the sound of the loud, rushing, cold water running down the back of Mokuba. The boy got out and slipped on the new clothes. He went downstairs seeing Seto waiting for him, his coat that defies all laws of physics on.
"There you are, Mokuba. What took you so long? Normally you're the first one up and downstairs." He said in a slightly concerned voice.
Mokuba looked down and shrugged his shoulders. "Oh . . . nothing . . . just had a dream . . ."
