Moonlight streamed through the bay window of Yuma's attic bedroom, bathing his sleeping form in a soft blue glow. His mouth hung open in a lopsided smile, left arm hanging down into the empty room, right hand clutching the now ever-present key around his neck. At least that was all his elder sister saw when she came to check on him, throwing a blanket over him to curb the unusually chilly night. "Sleep tight, little bro," she whispered, kissing his forehead and returning downstairs.
Astral watched Akari's intrusion into Yuma's room with interest, floating aimlessly above the stacked ancient paraphernalia. Once she had disappeared into the hole in the floor that served as Yuma's door, he glided down next to Yuma and tried to duplicate Akari's movements. His lips remained puckered, refusing to conform to the curve of Yuma's forehead. He frowned as he straightened to his full height. "It was humorous for awhile, but now it's just sad," a cruel voice reverberated in his head.
Astral turned around, shock carved onto his face. "How…?" His dark counterpart just smiled, sharp teeth stretching across his face.
"How can you be surprised? I am a part of you, after all."
"I locked you away!" Astral hissed, pointing at the Black Mist harshly.
"Locks were meant to be broken," the Black Mist glanced down at Yuma's sleeping body. "That is what the key is for." Astral suppressed the urge to slap the predatory look the Black Mist was giving Yuma off his face.
"Then I'll lock you up again-"
"But don't you want to TOUCH him?" the Black Mist suddenly cut Astral off, swooping in uncomfortably close, practically brushing their noses together. "I can touch him. Let me in, and you can too." Astral shivered as thoughts filtered into him: Yuma suspended in the air, pressed against him, lost in an emotion Astral didn't understand but desperately wanted. Astral pushed the Mist away, remembering the look of terror on Yuma's face from when the Mist had been free.
The Black Mist growled, tentacles growing from his legs, "How can you be so stupid? I see the way you look at him. You want him just as much as I do."
Astral clenched his fists, "And what if he doesn't want us?"
"Since when do you care what others want, my dear?" the Mist's tendrils played around Astral's legs. Astral looked down, defeat in his eyes.
"Never before I-" lost my memories.
"Then let's take what we want," the Black Mist wrapped around Astral, soaking into him. Astral nodded.
Astral looked at his hand, oily and congealed in a strange whirl of light blue and black. His body suddenly moved of its own accord, turning to face Yuma, who had turned over in his sleep, the blanket practically falling off him. "Yuma," Astral whispered, grabbing Yuma's shoulder for the first time ever. Something in his head told him to shake, he couldn't tell if it was himself or the Mist anymore. Yuma murmured sleepily, his red eyes blinking sleepily.
"Huh? Astral, how are you-"
Yuma's eyes widened, his tired look chased away by horror. And then he screamed. Astral panicked, pulling back, but his other hand shot to Yuma's mouth, silencing him. He could feel his mouth curving into a slasher smile. Tentacles lifted Yuma out of his hammock. Astral just stared into Yuma's face, wide eyes mirroring his captive. He (Or was it? He didn't know) slammed Yuma into the floor, their hips sliding together. And it was all worth it. Astral pushed his whole body against Yuma, rutting together and moaning.
He could feel his body darkening, the Mist controlling more and more as he lost himself in the joy of finally, finally feeling Yuma. He didn't care that he could only explore with his right hand, his left too busy keeping Yuma from screaming. He didn't care that he wasn't choosing where to move his lips anymore. He didn't even care that all he heard in his mind was insane lustful cackling. He felt like a coil was being tightened inside of him, until finally it broke, his entire body shaking.
Then the world came back into focus. Astral realized that he was probably crushing Yuma's chest with his hand if the bruise that was blossoming there was any indication. He managed to take control of his body back, flying off of Yuma.
"Oh, that was fuuun," the Mist's voice whispered in his mind as it oozed out of him, hands stroking his thighs tenderly. "We will have to do that again some time." The Mist disappeared back where it came from, leaving Astral staring at Yuma's newly bloodied body.
