He thinks my truck is sexy

The night sky was filled with stars and crickets sang their sad songs. Daisuke was running through the woods to his truck. He kept looking over his shoulder as if afraid that something might jump out at him at any second. He nearly tripped over a huge stone as he made his way over to dark omnious shape that was his truck. Though he was breathless, he smiled in relief. He was relieved that whatever had been chasing him hadn't caught him.
He reached for the handle and opened the door only to be thrown forward onto the truck seat. Something had pushed him forcibly and was now on top of him. He heard the door start to close and moved his legs in time before it slammed shut.
He could hear someone breathing right by his ear. It was panting, whatever that was on top of him. The panting wasn't of breathelessness but something else. Something lustful.
"Hello, my lovely," came a familiar voice.
"Nishi!" Daisuke nearly shouted "You were chasing me?"
"You seem so surprised to find out that it was me," Nishi playfully said "It's not like this is the first time I've chased you," With that, Nishi tugged Daisuke's shirt off and licked from the base of his neck to the small of his back. He grinned as he felt Daisuke shiver with pleasure "You know you love it,"
Daisuke only moaned as Nishi started to gently rocked his hips back and forth. Nishi was torturing him, he knew that but it felt so good. Nishi stopped rocking his hips and despite his small size, turned Daisuke over onto his back. Nishi brushed Daisuke's bangs back and stared into his human's eyes.
Daisuke blushed under the intense weight of the demon's green eyes. He started to squirm but Nishi held him firmly in place "Okay, I love it . . . I-I want it,"
Nishi grinned wickedly and got up. Daisuke sat up as Nishi unzipped his pants and his member sprang out. Daisuke's eyes grew wide at the sight. No matter how matter times he saw the demon's member, he was always surprised at how large it was.
Nishi leaned over and gently kissed him on the lips. Opening his mouth with his tongue, Nishi explored Daisuke's warm mouth like he had down a thousands before and like he would do til the end of time. While he was busy entertaining his mouth, Nishi grabbed one of Daisuke's hands and lead it over to his member. He guided Daisuke in stroking and caressing it. He lightly bit down on Daisuke's bottom lip and pulled him gently over.
Daisuke moved his hand up and down, slowly and tantalizing. He looked at Nishi as he broke the kiss then bent low. He wrapped his full lips around the top of the demon's hot and ready member. He started to suck, slowly. He started to move his head up and down, gaining speed with each movement. He heard Nishi moan and sucked harder. He felt Nishi run his fingers through his hair. Suddenly, Nishi bucked causing him to choke and sputter.
Daisuke was about to look up at Nishi when he was pushed down on his back on the seat. He felt his pants being ripped off and he watched Daisuke moved into position. He felt Nishi penetrate him with one finger, then two, then three and then four. When the fourth finger was in, Nishi started to slowly move his hand back and forth making Daisuke groan.
"Please . . . Nishi," Daisuke was tired of games, he wanted Nishi to bring him pain. He wanted pain to forget, to forget what he had done. He was a bad man, and he needed to be punished.
Nishi stared at Daisuke with sorrowful eyes. Daisuke punished himself needlessly. He remembered when he had found Daisuke. He had tried to kill himself by drowning. Daisuke was lucky that Nishi had been by that particular river that night. Daisuke almost screamed before Nishi realized that he had continued to gain speed until it almost tore Daisuke from the inside. That almost scream had done it. Nishi could sense the fear and pain behind it and it was enough.
He pulled his fingers out of the warmth and positioned himself at the human's entrance. He almost couldn't control himself and he bucked. He bucked hard in to Daisuke, causing the human to scream in pain which only turned the demon on. He pumped harder and more vigorously with each thrust. He heard Daisuke gasp and felt his seed splash up onto his stomach. Nishi wrapped Daisuke's legs around his waist and bucked and thrusted more powerfully. He watched Daisuke's face contort into a face of mixed emotions. Of regret and guilt, of pleasure and pain. It was delicious to see him like that. Nishi moved his hips faster and hard enough to make the truck move back and forth, adding to his momentum.
Daisuke and Nishi cried with blissful pleasure as they both came with one last, final thrust from Nishi. Nishi collapsed ontop of his human. They both panted heavily. Daisuke wrapped his powerful arms around Nishi "Th-thank you . . ."
Nishi gritted his teeth and turned his head as a single, solitary tear escaped and rolled down his cheek.
