Warning! This story may contain so Shuichi bashing. Please don't be mad Shuichi and Yuki fans. I had to do this pairing. I didn't find a lot of stories of them and the ones I did find kinda sucked.

Pairing: Yuki (Seme) and Hiro (Uke)

Chapter One: Fuck You No Fuck ME

"What the hell are you doing here?" Hiro said swinging his door open.

"I am here to talk to you, but now talking is far from my mind." Yuki smiled and pushed past Hiro, entering his apartment without his permission.

"I am not doing anything. You are with Shuichi, remember? He is also my best friend." Hiro slammed his door shut.

"Why get morals now? I have been fucking you for almost a week now. Besides, I don't care if he is your friend. Hell I could care less if he was your brother. I want you. I know you want me." Yuki walked over to the redhead. He looked Hiro up and down. He smiled. Hiro was wearing some extremely low jeans. They were tight and hug his body just right You could see the lower part of his abdomen. That was Yuki favorite part of Hiro. Those two lines drove him insane. He had on a white tank top or a wife beater. That was what Hiro called it. It also hugged his chest just right. Yuki was getting hard. Hiro's body was gorgeous with and without clothes. He was muscular but lean. With his red hair down , it just made him more fuckable.

"What is so fucking funny, asshole?" Hiro glared at Yuki. The blond hair man was making him nervous. He knew Yuki was right. He had been sleeping with him for almost a week. Hiro fucking loved it. Yuki would fuck him so hard sometimes he couldn't get out of bed for a whole day. He never let anyone take him before. Hell he never had sex with a man before Yuki. Yuki was truly a man that made you weak when he touched you or kissed you. Every time he heard his voice or seen him, Hiro would go hard instantly. Shit, he was hard now thinking about him.

"It is funny that you want to stop seeing me behind Shuichi's back. I loved the voicemail you left me. You know you couldn't end it, even if you really wanted to." Yuki walked closer to Hiro, backing him into the door. He pressed himself into Hiro.

"Don't do this, Yuki. I can't do this to Shuichi anymore. I… we.. Can't do this anymore." Hiro struggled to move Yuki away. He knew Yuki could feel his erection. He would used that to his advantage. Yuki put both his hands on Hiro's hips and started grinding his erection into Hiro's. Hiro bit his lower lip so he wouldn't moan. The friction Yuki was causing felt so damn good. He knew that if he moan Yuki wouldn't let up.

"Do you really want me to stop?" Yuki grind harder into Hiro. Hiro whimpered a little. He still refused to moaned. He bit his lip harder almost drawing blood. Yuki could tell that Hiro was trying to hold back. He decide he would break the younger man. He would make him want it so bad that his body would tremble. Yuki slipped his hand up Hiro's shirt and began to play with his left nipple. Hiro let a moan escape his lip.He knew it was his weak spot. Yuki pinched the nub making it grow hard. Hiro moaned again. Yuki kissed the redhead hard. He played with the others tongue with his tongue. He wanted to taste every inch of Hiro. Fuck , he was such a damn turn on. He broke the kiss letting Hiro breathe. He began sucking at the boy's neck. He nibble and bit at his neck. He didn't care if he left marks. He wanted to let people know he belong to him. He bit roughly into Hiro's neck causing him to wince.

"Yuki. Please…stop." Hiro moaned. Yuki was putting him close to the edge. He wouldn't be able to think clearly if Yuki didn't stop. Why was he so not himself when the blond was around.

"No, I am already hard. I don't intend of leaving until I fucked you to sleep." Yuki throw off his jacket. He dropped to his knees and started unbuttoning Hiro's jeans.

"What are you doing?"

"What the hell does it look like I am doing?" Yuki pulled off Hiro's jeans and boxers in one swift movement. He tossed the pants behind him. Hiro's cock was standing at attention with precum oozing off of it. Yuki licked the head first. That caused Hiro to tremble slightly. With that Yuki began to suck Hiro off. He was going slow at first. Going up and down Hiro's length slowly while wrapping his tongue up and down the length in the process.

"Fuck.!" Hiro yelled. He entangled his fingers in Yuki's blond locks. Yuki began to pick up the pace and deep throat him. He tighten his grip around Hiro's length. He began playing with the redhead's balls. Hiro's legs began shaking. He started thrusting into Yuki's mouth. He didn't go hard but when Yuki picked up the pace, he thrust harder. Yuki didn't mind instead he grabbed Hiro's hips to pull him in deeper. He was now touching the back of Yuki's throat. Hiro started literally fucking Yuki's face.

"YUKI! I am about to come." Hiro screamed. Yuki deep throat him one more time. Making Hiro cum hard into his mouth. Yuki didn't swallow, he was going to use Hiro's load for lube. Hiro's whole body was trembling now. That was the most powerful orgasm he had ever experience. He was so caught up in his orgasm that he didn't even notice Yuki had taken off his pants and used his cum for lube. The next thing he knew Yuki picked up his left leg, placing it on his right shoulder, and slid inside him. He was now trapped between the door and Yuki.

"Ahhhh…Fuck. You are still so fucking tight."

"Mmmm.." That was all Hiro could say. Yuki began pounding into him. Hiro was getting hard again. Yuki picked up Hiro's other leg and held it up. This cause Hiro to open up more and Yuki struck his spot.

"Oh SHIT! Don't fucking stop." Hiro wrapped his arms around Yuki's neck, taking Yuki in deeper. Yuki picked up the pace. Moving in and out of the redhead swiftly striking the younger boy's spot every time. He could feel Hiro legs trembling again. Hiro felt so fucking good. He loved fucking Hiro. He was so warm and tight. Damn. He loved how Hiro would tighten his muscles every time he pulled in and out of him. He know he couldn't hold back anymore. He felt Hiro start scratching at his back. Luckily, he hadn't taken off his shirt. He would have a hard time trying to explain scratches on his back to Shuichi, but Shuichi was so dumb he probably would believe anything he told him. Yuki began to suck on Hiro's neck again causing the young man to scream. Yuki was now fucking him harder. Hiro wrapped his legs around Yuki's waist causing the blond to go even deeper. He was close to another orgasm. Yuki began to stroke Hiro's erection. He was going the same pace as his thrusts.

"Yuki, I am cumming!" Hiro screamed. He tighten around Yuki, causing him to cum hard inside him. Hiro followed only seconds later all over Yuki and his shirt. Hiro's body went limp in Yuki's arms. Yuki slid out of Hiro and lower them both to the floor. He was on his back while Hiro was laying on top of his chest. He didn't even let Shuichi do that. The carpet felt somewhat cooler on his warm skin. He wrapped his arms around Hiro.

"I knew you wouldn't stop me."

"Huh… I am so tired." Hiro was listening to Yuki's heart. The rhythm was so soothing. His body felt so weak. He couldn't even move. Yuki did this to him often. He knew he would not be able to stop messing around with him anytime soon. He was having an affair with his best friend's boyfriend and all he could do was close his eyes and drifted into a blissful sleep.

"I guess I will be spending the night." Yuki reached for the jacket above his head and covered Hiro with it the best he could. He knew the redhead was asleep. He started running his hands through the his hair. His hair was so soft.

Even though he knew Hiro could not hear him. He had to say it, because he would never let Hiro know when he was awake. "I couldn't leave you alone, even if I tried." It was something that attracted him to Hiro. He was intelligent, confident, sexy, not clingy, and he didn't nag him or annoy him. Hiro didn't talk to him like he was going to break or like he was fragile. Even though he knew everything that was going on with his past and Shuichi, he never made him choose. He was never thinking of himself. Only about not hurting Shuichi. He knew that eventually they would have to break it off. But Yuki didn't really know if he could. Even though they only been together physically for less than a week. He was attracted to Hiro before the affair. If Hiro asked him to leave Shuichi today he would do it, but he knew Hiro would never let him. He could respect that, but he didn't like that. He thought about leaving Shuichi many times but he didn't want to upset Hiro or lose him, at less not yet anyway.

He loved being with Hiro. He loved the way he smelt. He smelled like fresh cotton and a light but appealing musk with a hint of cinnamon. The way he kissed him. He was such a passionate kisser. Hiro always kissed him like he was never going to see him again. He loved the way he tasted. He tasted almost like cinnamon or brown sugar. Yuki would lick his neck sometimes just to get his daily fix of Hiro. His skin felt great. It was so smooth. He never knew a man's skin could be so soft. It was like silk. The days he didn't get to see Hiro, he was anxious and annoyed at everyone. But when he was with him he was so calm. He didn't care about anyone expect for Hiro. He didn't know if it was love, but he knew it was a pure addiction. He was addicted and didn't care. Yuki didn't want to think about their situation anymore he just wanted enjoy the night with his lover, with his obsession.
