It started in high school. 

Naruto's reliance on drugs, he had hidden it well that he had dipped his toes in that side of the city. He worked the street selling for extra cash and eventually all dealers tasted their products. He wasn't any different, it started with weed and worked his way up to pills and plunged over the edge into cocaine addiction. He was too greedy, snorting his product rather than selling and if he did sell he stepped on the coke with baby powder so he could have extra. 

He was caught and beaten out of his circle and no one would sell to him. He had a mental break, one that had Shikamaru kicking in his door to see the mess he had become. Pressed into the farthest corner of the room, Naruto looked at his best friend with distrustful eyes. His wrists were bleeding from him trying to quell the urge that was crawling throughout his body. He needed a rush, he wanted more. 

"You pathetic animal, scurrying into a corner when your belly is empty," Shikamaru snarled, he wasn't pleased. He knew Naruto had gotten into drugs, he's always had people watching Naruto. He wasn't upset that he was using, he was upset the blonde never came to him once for help. He just lied to his face when he asked if he was alright. 

Naruto whimpered, trying to find a way to get out but he had nowhere to go. "I'm sorry, sorry, sorry Shika," He apologized as Shikamaru grabbed him by the shirt. 

"Shut up," Shikamaru snapped. "What have I always told you?" 

Naruto couldn't formulate words, his tongue had gone heavy in his mouth as his vision blurred. Shikamaru could see he was on the verge of passing out from withdrawal and he sighed. He pulled a needle out of his pocket. It was liquid cocaine. The highest stuff on the market, only the wealthy had access and here he was using it to feed his obsession. He felt around Naruto's forearm before finding the spot and injecting him. Naruto could barely see him do it before he falls unconscious. 

*********

"Shika~" Naruto moaned the Nara stripped him. 

"Do you like it? It's a new drug to make you excited for an entire night," Shikamaru kissed around his neck, trailing down as he got the blonde's shorts off, he was already so hard. Naruto had cleaned himself as requested so putting his tongue inside the heated blonde's entrance was much easier. 

"Hot, it's too hot," Naruto opened his legs as his back arched. Shikamaru was pleased with him, he pulled back from the blonde's slippery entrance and rinsed his mouth before pulling the blonde against him. He was hot, that was the drug but his cock was drooling precum and it looked like he could give in at any moment. 

"Alright, I'll cool you off," Shikamaru sucked a mark into his chest, fondling his nipples as he stroked their erections together. Naruto spasmed, his hips moving in Shikamaru's fist as his vision became hazy. 

"Coming, not yet," Naruto choked out as he threw his head back. He was too sensitive and his body was racked with pleasure as the drug ruined his senses. Shikamaru grinned as he got the blonde to sit on him. He laid back on the bed and fully sunk into Naruto's sweet pussy. Shikamaru shushed the blonde who was sobbing as he held both of his hands and told him to start moving. "It's too much, Shika please." 

Shikamaru huffed in an annoyed tone. "You told me you wanted this and now that you have it you want to go back on our deal. Isn't that a bit unfair?" 

Hearing those words made Naruto whimper. "Yes, I'm sorry," He leaned down to kiss Shikamaru's face through his tears. "I'm just overwhelmed, I'm sorry."

He started moving even though it was obvious he was about to lose his mind but Shikamaru had already lost his when Naruto's walls were clinging to his cock. He snapped his hips up as he grabbed the blonde's hips, bruising him as he used Naruto for his own pleasure. Naruto cried out, his entire body drowning from Shikamaru sadistic nature as the Nara ignored his pleas, that he was hurting and it wasn't pleasure anymore as his body had gone over into oversensitivity. 

Shikamaru slapped him and Naruto's voice choked in his throat. "Shut up," He growled, the blonde sobbed but he bit his lip as Shikamaru used him. 

**********

Naruto was crying under the sheets trying to tear his hair out as withdrawal plagued him. It had been two days since his last needle and he had already started clawing at his arm. He heard the door to his bedroom open and knew it was Shikamaru. "Please," He started begging. "Shika," It was so desperate. 

Shikamaru pulled off the covers and gazed at his bruised ankles and hips. He was in a single black baggy shirt, the sheets bloody from his arms. The Nara scoffed as Naruto started pawing at his belt. "Stop it," He said coldly. "Don't you have any shame? Being a prostitute for a needle?"

Naruto looked up at him, his eyes wide and hungry and Shikamaru knew the blonde wasn't seeing him. It made him angry. Didn't Naruto see how much he cared, he was feeding the blonde's addiction but he really only cared for the drugs. He whacked him across the face. Naruto's mouth pooled with blood that drained onto the bed as a part of a tooth came out as well. His messy soaked hair covered his eyes but they were watered with tears. 

"Do you even see me?" Shikamaru yanked his head back, his neck snapping harshly as the blonde looked into the dark eyes of his lover. Could he even consider Shikamaru a lover? 

"Of course, I see you," Naruto's voice came out wobbly from the pain that was inflicted on his jaw. "Shikamaru takes care of me, he feeds and clothes me, gives me needles when I need it- ah!" 

Shikamaru pulled on his locks tighter but Naruto got excited from the treatment. He had gotten used to his tactics, he melted at it. His shirt had moved to show his hardened member and Shikamaru chuckled darkly at seeing it. "You're getting off to this," He observed as he pulled on his cock, Naruto panted, his hips rolling upwards into his hand. "The things you do to me."

He kissed Naruto, feasting on his blood as he unbuckled his pants and got his erection out. When he pulled back he nudged Naruto's mouth down to his cock. "I want your blood on my cock," He smirked as Naruto swallowed him, his gag reflex kicking in but Shikamaru didn't care as he forced himself down the blonde's throat. He groaned, thrusting into his mouth with shame. "Make sure you lube it properly, I'm not preparing you." 

Naruto closed his eyes, his face pink and blissed from sucking on his lover's cock as he stroked his own. Shikamaru ran his fingers through the locks with an almost fond expression. He pushed Naruto into his pubic hair and had him rest there, marinating his cock in blood and saliva before pulling out and turning the blonde around. He did what he said he would. He took Naruto without prep, they both moaned as the blonde pushed back into Shikamaru as the Nara drove his way into the tight entrance. 

The marks on Naruto's hips had barely begun to fade before Shikamaru was placing new marks. The blonde buried his face into a pillow as he was taken from behind by his violent lover who had slowly taken out a new needle. As he fucked the blonde he grabbed Naruto by his neck and pulled him into his chest. He turned Naruto's head to kiss him as he grabbed the blonde's ruined arm and plunged the needle in. Shikamaru saw the sparkles in Naruto's eyes and threw the used needle elsewhere as they got back to business.
