Good day everyone! I apologize once again for the late update. Mainly because of school :V I actually shouldn't have worked on this now either but meh xD First off, I want to thanksPaulie MickyJ for pointing out mistakes in the previous chapter~ And secondly I want to thank South Boy for encouraging me to write this and beta'ing. I needed the encouragement because I've never uploaded anything M-rated before and I barely write dirty stuff so I'm sorry if it sucks HAHA ok bye.

Somewhere between the trees, a white car was parked in a dark spot. Outside was cold, but Law himself found himself in a space where it was rather the opposite of that. It was only a few weeks ago, when Monkey D. Luffy, Law's student, confessed his feelings to the older man. At first, Law tried to hold back, but it was difficult when Luffy was the first one to initiate their love-making. With every lesson, their interactions got more intimate step by step because of his curiosity.

It started with a deep kiss, where their tongues clashed against each other. They lasted until all the oxygen was gone and had to end their hot, steamy kiss. The week after it was even more affectionate. It was from then on that Law realized how sensitive the boy was in general, despite acting naive all the time. Step by step, he knew most of his favorite spots. On his chest... His thigh... His back... Everywhere. Not one lesson elapsed without touching the younger male in some loving way. But Law couldn't help it, not when Luffy used his attractiveness to seduce him.

Today it was a few lessons later and Law still wasn't tired of Luffy's face and body, but most importantly his playful and cheery personality- the opposite of the man itself.

"I caught you again!" Luffy shouted enthusiastically as his hands rested on both sides of Law's shoulders and his face facing the man. His head was nearly touching the car's ceiling so he had to lean forward to not hit his head. They were in a cramped seat, but that only added a more intimate effect. He placed his legs next to the sides of the seat, giving him no chance to escape.

Law smirked in return and was glad to know that he wasn't the only one who grew a sexual side after meeting each other. But how could he not turn into a pervert when Luffy was literally inviting him?

And with literally he meant when Luffy made a grinding movement on his lap as a declaration to start their activity.

Law managed to stifle his grunt as he did not want to give in that quickly, especially not from only a grind.

"Impatient aren't we Luffy-ya?"

"That's because Traffy's always taking his time!"

Well Luffy wasn't exactly lying about that. Law wanted to make sure he knew all of his sensitive places on the raven-head's body. He really should do something about his nickname though...

Law tilted up his head and leaned forward, but stopped before his lips brushed Luffy's. While he tried to catch the dark-colored eyes right in front of him, his index finger moved smoothly from stomach to the chest. With the tip of the upper joint of his finger, he rubbed the teen's nipple through the fabric and watched the changing expression from close. "How long are you going to continue this nicknaming-game, Luffy-ya?"

Luffy's eyebrows knitted from the small arousal and grinned challenging in return. "I'm not giving up your nicknames," he responded firmly.

The instructor let out a small chuckle. "Stubborn aren't we?"

The teen laughed as response. "I don't wanna lose after all."

Law always liked it when Luffy challenged him. It added some extra spice in their relationship, even though there was already a lot. While Luffy won most of the challenges (because he was so persistent), Law knew Luffy's body very well and didn't plan on losing this one.

"I wonder about that," he whispered and locked their lips together to end their short conversation. Luffy's arms automatically wrapped around the man's neck until a moment later he broke off the kiss and pouted.

"Tra-guy! We've done this every week. I want to do the cool adult stuff!"

The taller male sighed in response. "Luffy-ya, this kind of thing need time, you understand?"

"But I'm not some dedicate girl," he argued.

"It's delicate.", Law corrected. However, now he got curious again. With an argument like that, Luffy couldn't be as innocent as he sounded. Either he had done some research on 'sex' to understand some morals or actually experienced something in real life. "Also, what are you implying."

"Well Sanji said-"

"I don't think you clearly know the danger here, Luffy-ya," Law interrupted, already knowing how Luffy got all the information.

"We're going to make love aren't we?" the straw hat boy questioned with his pure eyes.

"It's going to hurt," Law warned honestly. Despite really wanting to thrust inside the boy until both of them came, Law didn't want to force him, no matter how much he had to hold himself back. He was patient, especially now that he had already come this far.

"No worries! Grandpa's punches are really painful as well you know!" Luffy persuaded.

"This isn't some fight we're having," Law argued in return.

But if he really wants to do this...

Law looked up and directly gazed at the younger male. He lifted his hand higher and gently stroked the boy's cheek with his finger. "But all right. I'll drive you home afterward if you've really made up your mind."

Luffy smiled widely again. "Yeah!" he replied and gave him a quick, short kiss.

Law moved slightly pulled back his backrest in order to create more space. His hands wandered from the chest to the waist and finally to the back until they were low enough to slip underneath Luffy's pants. With a squeeze, he pushed the boy closer to him, their chests touching. Luffy, who still had his arms wrapped around the man's neck, was bended flexibly on top of him.

"Hold tight," Law ordered and tightly gripped the teen with one arm. He extended the other arm to open the glove compartment and grabbed the lube before closing it again. Luffy who couldn't see what he was taking from behind, only gulped while still being latched to the older male.

"Traffy?" Luffy called with a soft voice.

After Law leaned backward again, he could see the questioning expression on the teen's face as Luffy's wide eyes were fixed on him. "It's lube."

"Lube?", he wondered again which made Law wonder how much detail Luffy's cook had left out and what not.

The older male nodded. "Just focus on relaxing," he suggested and pulled off the cap to open the tube. While he inserted his two fingers to take out some of the substance, he felt Luffy watching again who was being unable to understand what his instructor was doing.

Law stared back at the teen again, who was much more quiet than a few minutes ago much to his surprise. Though Luffy was and probably never will be a romantic, perhaps he could feel the mood after all.

"Your legs Luffy-ya, can you spread them wider?" the instructor requested. Luffy did as he was ordered for once and widened his legs. Law pulled down his pants until they were lowered to his knees while Luffy held onto him. His coated finger slipped between Luffy's butt cheeks, touching the entrance. Pushing his index finger further, he slowly invaded the teen inside.

Luffy was still above him and close to his face, which made it easier for Law to read his expressions. His eyelids were closed, but there was no sign of pain, only discomfort.

"Relax more..." Law advised again as he noticed how tight his student was.

"Even if you say so..." the teen responded in a somewhat troubled manner. Law who directly took note of that, began to stroke Luffy's shaft with his free hand, hoping that it'd ease the displeasure.

The change inside Luffy confirmed Law's prediction, because after a while he was able to loosen the boy by moving his finger. It didn't take long before he added another finger and continued to stretch him from behind.

Luffy could endure a lot, but Law could see that that he was trying hard to keep his voice low because his teeth gritted to hold himself back. Fortunately for the patient Law, he had other options left to make the teen raise his voice.

His two fingers moved even deeper inside of him and searched for a specific place- that one sensitive spot that Law hadn't discovered yet. He searched and checked for it, digging deeper as he was exploring inside. When he curled his finger and touched a bump, the teen immediately gasped which indicated that Law had found it.

"Traffy!" Luffy cries and tightened the grip on Law's back.

"Oh? Finally opened your mouth?" Law answered in a somewhat teasing voice. "Did that feel good?"

The straw hat boy didn't answer again and for the first time, Law was in control. "You might want to remember the feeling," Law considered. Without any further ado, he pulled out his digits, wanting to replace them with something bigger. With half-lidded eyes, Luffy looked at the man in confusion.

"Traffy?"

Law unzipped his own pants, freeing the hard-on that was making him uncomfortable underneath the fabric. He felt Luffy staring quietly at it and heard a gulp coming from the boy's mouth.

"Are you backing out now, Luffy-ya?" Law said with a hint of fear in his voice. He didn't want to stop now and possibly can't either...

The boy shook his head 'no'. "I'm not!" he fought back, making sure to let know that he didn't want to stop now either.

"Just... impressive size."

The man smirked from the compliment, but was also a bit surprised from his willing reaction. Now both hands grabbing the teen's hips, Law lifted him up and adjusted him above his lap, the tip touching the stretched entrance.

Law leaned his face closer to Luffy, his mouth near his ear. "I'll give you some piece of advice," he started in a threatening voice. "You might want to start calling me by my real name now."

The teen grinned. "We'll see about that," he responded challenging.

Law gave him a sly smile one more time before he slowly entered the boy with the tip of cock. Luffy held dearly onto him, his arms still wrapped around the man's shoulders, preparing himself for more. His mouth opened to let out another soundless gasp because of the sudden intrusion in his back.

Law pulled out again but re-entered to dig deeper. The thrusts were slow-paced and out of rhytm, but he knew better than to rush their first time. The friction between him and Luffy felt hotter with each movement and before he knew it, he was already fully inside him.

Luffy moved along the pace, both feet next to the sides of the chair to help himself pull himself up. His painful expression gradually changed into a way pleasant one, meaning that he was starting to enjoy it as well. His face was still close to Law's and even more red than when they started. Despite the chilly cold outside the car, sweat fell from his chin, but it was also underneath his vest that made the clothing stick to the body.

Both males were moving, meeting each other with every thrust. Law could feel Luffy's hot breath on his skin, but soon took it by putting his own mouth on his. The kiss was wet and salty, yet he couldn't ask for a hotter kiss despite it being sloppy.

"Traffy..." the younger male called softly from being out of breath.

"It's Law," the man corrected in the same manner and quickly kissed him again as he still hadn't enough of the taste.

Now that they had a steady pace, Law tried to shift the younger above his lap while trying to search for something that he could remember well. Trying to thrust deeper in a different angles, Law was able to hit the younger's prostate in no time.

Luffy moaned out loudly from the sudden pleasure. His eyes widened from the shock and his grip probably was going to leave marks on Law's back for at least a week.

"T-Traffy!"

Law made sure that the following movements didn't hit the bump again, but by the way Luffy was shifting, he knew that the boy was searching for it anyway.

"Traffy... I want 'that' again!" Luffy cried out.

"'That'? We had a game going on, remember Luffy-ya?" Law teased. However, he wasn't sure how much longer he was able to go on. He too, had his limits, was sweating heavily and could feel the strength in his arms being sucked away with every second. He just hoped he could hold back long enough.

"Traffy!"

Without giving in entirely, Law lightly brushed the sensitive spot. The tiny caress was enough to remind Luffy who was the boss in this play. Law just hoped that playing the boss was enough to make the straw hat boy listen...

"-aw!"

"I can't hear you yet."

"Law! Give me 'that'! P-Please!", Luffy's desperate cries continued. Law who was satisfied with the answer, gave him his wish. They went fully back to their old steady pace again, both wanting to release themselves. Every time Luffy landed down, he'd moan loudly in ecstasy until he could scream no more. It only took a few more thrusts before the younger came after a last hard thrust.

"Law!" Luffy cried one last time and released a teaspoon of white liquid. Law could feel Luffy suddenly tightening around him, the inner wands wrapped around the man's cock, causing him to soon come after Luffy.

Luffy's head soon fell against the man's chest. Both were panting hard and trying to catch up their breath from the exhausting session. Meanwhile, Law wrapped his weakened arms around Luffy to pull him in a comforting hug and still couldn't believe himself for a moment.

"Hey, Luffy-ya," Law called out to him after regaining his oxygen, but for some reason it stayed silent. When Law wanted to take a better look at the boy between his arms, a loud snore appeared from the student.

"Don't tell me..."

Not trusting his eyes, Law pulled him a little backward, enough to be able to take a good look on his face.

That's when he was certain: Luffy was indeed, sleeping. His eyes resting and mouth open, probably dreaming of all the food he had eaten today. The man sighed in respond, but couldn't help but smile afterward.

He was going to drive him back anyway.
