As soon as the couple were inside the room, Haru slammed the much larger male to the wall. Haru leapt into Yuujin arms and started to roughly kiss Yuujin. Yuujin moved away from the wall and closed the door while still holding onto Haru and kissing him with equal intensity. Haru's mouth moved south to Yuujin's neck. Yuujin quietly hissed at how harsh Haru was but did not care because the pleasure he received canceled out the pain, Haru intended to leave his boyfriend with large purple welts, marking Yuujin as his, and his alone.

Haru tried to kiss and nibble even further south on Yuujin's body but articles of clothing prevented from doing so. "This won't do, Yuujin," Haru stated.

Yuujin hazily replied, "What do you mean?"

Instead of answering, Haru removed Yuujin's sweater. Yuujin did the same to Haru. The couple went at a quick pace stripping each other, both quickly wanting to go back to feeling the other.

Before they removed each other's last piece of clothing, their underwear, the couple pressed their bodies together and mouths met once more. It was a desperate kiss, tongues frantically moving within their mouths. The green-eyed teenager kept their bodies close together, while Haru, keeping his lips attached to Yuujin's, placed his hands on Yuujin's hips.

Without removing his mouth from his boyfriend, Haru freed Yuujin's cock. Haru went down on his knees and gazed back at Yuujin.

Yuujin flashed a cocky grin. "You like what you see down there Haru?"

Haru uttered "uh...yeah." Haru forgot how huge his android lover was. He created his latest body based on the YJ-14 model and made modifications of how Yuujin would look at 17, if he was human. Leviathan for some odd reason made Yuujin extremely endowed.

Haru, however, would not be deterred. He had never done this with lover, but his lover had sucked him off time and time again. Haru didn't feel that only he should gain pleasure from this. Yuujin deserved it too.

Haru started the session by slowly licking the head of Yuujin's member. Slowly, Haru started to wrap substantial portion of the tip with his tongue. Haru then put the whole head in his mouth. Haru tried putting more of the thick and large flesh into his wet crevice but had to stop. He realized Yuujin was far too large to successfully imitate what the porn stars did. Nonetheless, Haru could still make the other parts of Yuujin's cock feel good. Haru did this by using his hands. They helped by gently rubbing on the lower half of the exceeding large organ. It seemed to be successful. Haru's gaze caught a glimpse of Yuujin's face. His boyfriend's eyes were closed, and his mouth made an O shape.

Haru wasn't quite too worry about his boyfriend feeling pleasure down there. While this may be Haru's first time doing oral on his boyfriend, Haru hands had grown quite acquainted with Yuujin's lower half. No, what Haru worried more was making this new experience between him and his lover a fun and pleasurable moment. However, the fun didn't last long.

"Ow," Yuujin uttered. "Haru try not using your teeth."

Haru quickly removed his mouth out from Yuujin's cock. "Oh, my goodness, I'm so sorry Yuujin."

Yuujin looked down and saw what he thought was the most delectable scene on the planet. Haru with foggy eyes laden with lust, his mouth leaking liquid, and both his hands wrapped around his cock with Haru's face right next to it. "Damn, you look so beautiful like that Haru."

"Yuujin..." Haru face lit red, embarrassed but flattered by his boyfriend's compliment.

Yuujin enveloped Haru with his arms and lifted him off the floor. He tossed Haru onto the bed and trapped him under the weight of his body. Haru protested, "Yuujin let me go, I'm not done yet."

Yuujin silenced his boyfriend by connecting their mouths. The reunion between their lips was slow and gentle. While tasting another, their hands roamed their bodies. The lovers found each other's' bodies to be irresistible. For Yuujin, it was Haru's pale and smooth skin. He let his fingers rubbed up and down Haru's back. For Haru, it had to be his boyfriend's muscles and toned body. It didn't help that when Haru's fingers were touching the bumps and curves of Yuujin's upper chest, Yuujin flexed his muscles. It shivered down Haru's spine and blood to his organ.

Haru's hands moved down and roughly touched Yuujin's flat and defined stomach. Haru loved taking his time to explore the body he created for his boyfriend, but he still had his mind set on completing his objective.

The pair was still kissing when Haru's hands finally reached Yuujin's cock. Hands playfully touched said cock. The owner of it moaned his name, "Haru!"

Haru cried out, "Yuujin, I cannot take it anymore. Let's start."

Yuujin paused for a moment. His face smeared with the same color as his hair. Shame took hold of him due to ignorance of how to proceed. "Haru, I don't even know how this works."

Haru held in a chuckle, now was not the time to tease his boyfriend. He placed his hand on Yuujin's cheek and brought their foreheads together. He stared into Yuujin's eyes and said, "I'll tell you what to do."

Haru jumped off the bed and immediately went to his backpack. Not a few seconds after, Yuujin saw that the green haired teen pulled out a purple bottle.

"What is that Haru?" Yuujin pointed to the strange object in his boyfriend's hand.

Haru shined on him a warm smile. "It is lube, Yuujin. This is how we are going to make you fit inside me."

"Haru what are you talking about?" Yuujin was at lost to what Haru meant.

Haru's hand reached down and lightly squeezed Yuujin's throbbing member. "This, we are going to put this inside me." Haru then pointed to his hole. "And put it inside there."

Yuujin's eyes widen in shock over the words he heard from his beloved. "Haru there's no way that'll work. I'll hurt you. Please no."

Haru gave a light peck to his boyfriend's cheek. "It'll be fine, trust me." But if Haru was being honest, he had some reservations. The protagonist failed to recall while conducting his "research" that none of the specimens he viewed had anything comparable to the size of his partner.

"Ok Haru I trust you." Yuujin said with eyes that shone bright with confidence over him.

Haru smiled to his love. "Yuujin I want you to watch me and then do what I just did."

Haru opened the bottle's lid. He poured a good amount of lube on his fingers. Haru hovered his hand near his hole. Haru slowly inserted his index finger into his passage. He waited a few moments before slipping in another finger. Haru moved the fingers in and out of his crevice.

Following a few minutes of thrusting them in and out of his passage, Haru gently removed his fingers. He grabbed the bottle of lube and squeezed an ample of amount on Yuujin's fingers. Haru placed Yuujin's lube ridden fingers to his waiting hole. Yuujin took the hint and gently popped in the tip of his index finger inside his green haired lover before plunging his entire finger. Then Yuujin inserted another finger inside.

Haru noticed that the sensation was different from before. Yuujin's fingers were much larger than his own. It was hard to adjust to this new feeling, the feeling of being overfilled. However, just the idea of his boyfriend's finger inside of him made the blood in his arousal harden it. And just like Haru, Yuujin pushed the fingers in and out. However, unlike Haru, Yuujin added a third finger. Haru felt a shortness of breath. Haru tried his best to deal with the new feeling. He knew that if he couldn't take Yuujin's fingers, he would never be able to take Yuujin's cock.

A few more pumping of Yuujin's fingers in Haru's tight hole and Yuujin spoke up, "Haru is this good enough?"

Haru tensely replied, "Yeah it should be."

"What next?" Yuujin questioned him.

Haru laid on his back side told Yuujin, "take the bottle and squeeze some of the liquid onto your palm, rub it on your...penis and then put it inside me."

"Haru are you sure about this, if you want to stop at any time, please tell me."

Haru grabbed his partner's arm. "Yuujin I want this, please continue."

Yuujin did as instructed. He grabbed the lube and place an amount of it on the palm of his hand. Yuujin rubbed the liquid on his length. Haru previously had his eyes closed but now had them wide open. His view was directed straight at his boyfriend's shaft. His body started to tense. Deep in the recesses of his mind, Haru started to have second doubts of being able to fit Yuujin inside him.

Yuujin lifted Haru's legs and placed them over his shoulders to give himself better access to Haru's pink hole. The redhead steadily sunk the head of his cock into the warm heat of his lover.

Haru was not prepared for this. It stung. This felt unlike anything he had experience before. He hid his discomfort and need to moan in pain. Haru only made matters worse by not telling Yuujin the truth. He instead opted to endure the pain.

"Continue," Haru weakly said.

Yuujin continued to push his length more into the tight entrance. Yuujin, however, became concern. Haru kept quiet, no longer making his previous noises of pleasures. While they were fingering Haru's hole, the smaller male made plenty of moans, but now none. Nonetheless, Yuujin decided to press on. But, when he was two-thirds in Haru, he caught Haru trembling and tears were rolling down his face. Yuujin gently removed himself from Haru.

Haru suddenly noticed the blunt pain disappeared and a sense of relief engulfed him. He realized that Yuujin had withdrawn from him. "Yuujin what's the matter. Why did you stop?"

Yuujin dejectedly responded, "I'm sorry Haru this cannot continue. You are hurt, I am hurting you."

Haru sat upright on the bed. "Yuujin, I'm fine."

"Haru I saw you crying and trembling. This is hurting you. Please don't lie to me."

"Ok, I'm sorry Yuujin. I'm weak and I couldn't handle it." Haru's voice cracked.

Yuujin held Haru close to him. "Haru you are not weak, you are anything but that. This is our first time. So, you underestimated this? Big deal. Mistakes will be made." Yuujin flashed a warm smile to him.

Haru loved how sympathetic his boyfriend was. "Yuujin."

"If you want we can do something else, maybe just cuddle?" Yuujin offered.

While the offer was tempting, Haru was too stubborn to not continue. However, a thought occurred to him. Maybe it was the position that was the issue? Maybe he needed to try a different position? He figured it was worth a try.

"Yuujin I have a suggestion."

"Oh, what is it." Yuujin wondered what it could be.

"Maybe the problem was our position. Maybe because we our beginners, we need to try positions that are easier on me," Haru explained.

"So, what you are saying is that you want to try again? I don't know about that."

Haru put clapped his hand together and pleaded with his lover, "please Yuujin, let's try one more time. Do it for me."

Yuujin relented. "Ok fine, anything for my Haru. But if I start noticing that this is painful for you we will stop and go straight to bed, is that understood?"

"Yes!"

Yuujin asked, "ok so what do we teach?

"Lay down." Haru ordered his cybernetic lover.

Yuujin laid on his back. Haru used the bottle to squeeze an ample of amount of liquid to his hand. Haru stroked Yuujin's cock with the gooey watery lube.

Haru sat himself on top of Yuujin's stomach. Haru lifted himself slightly above Yuujin, his hand reached behind to hold Yuujin's cock while his other hand he placed on Yuujin's chest. He used the hand on Yuujin's chest to keep his balance while he positioned his hole next to his lover's arousal.

Yuujin felt totally exposed and defenseless, nonetheless, he trusted his partner. This trust was only reinforced when Haru looked at him with pure love in those blue pupils.

"I love you Yuujin."

"I love you Haru."

Haru gently allowed the head of Yuujin's cock to breach him. Haru soon realized that this sensation didn't feel as painful as the previous attempt. Haru chose to take in another inch of his boyfriend. And then another. Haru waited a couple more seconds of trying to get used to the feeling.

He looked down to see how Yuujin felt. Yuujin's face screamed flustered, his eyes were closed and his breathing staggered. Total bliss described him. It made the blood rush to Haru's cock knowing he was able to create such reaction in his boyfriend. In fact, it encouraged Haru to take in a few more inches. After minute of waiting and adjustment, and Haru had finished enveloping all of Yuujin's cock. At last, Haru and Yuujin's bodies were fully connected.

"Wow." Haru uttered suppressing his desire to moan in pleasure.

"Yeah wow is right." Yuujin said who was still lying down on the bed with his head on a pillow and red plastered all over his face.

"So, this is sex?" Haru asked with his breathing showing irregularity.

"I guess... so what now Haru?" Yuujin huskily responded.

"Give me a minute, it's a lot to take in." Haru didn't intend to say that as a pun. The fullness and the pain becoming pleasure had made him lose this train of thought.

Yuujin placed his hands on Haru hips and gently rubbed them, encouraging Haru to move. Haru slowly lifted himself up using his hand on Yuujin's chest to keep a steady balance. He stopped when most of Yuujin's cock was freed again, minus the head, and slammed back into his green-eyed lover. Haru's back arched following the reunion between Yuujin's cock and his hole. He let out a mild whimper, signaling his growing pleasure.

"Haru!" Yuujin moaned.

Haru repeated his action. The next thrust, however, Haru went faster, and then the next thrust even faster. A few more thrusts and Yuujin lifted his back off the bed. No longer content with just lying down, Yuujin wanted more intimate contact with Haru. Yuujin pressed their chests together, Yuujin's abs trapping Haru's cock between them. While Haru was bouncing back and forth on his cock, Yuujin wrapped his arms around Haru and began to suck on Haru's slender pale neck. In addition, Yuujin started to equally participate in thrusting into Haru's body, using his hips to meet Haru's slams.

The friction between Haru's cock and their two bodies, Yuujin's suckling, and Haru and Yuujin both working together to hit a certain spot in Haru's passage made the green haired youth reach the breaking point. However, despite lucid, Haru knew Yuujin's body better than anyone. The larger teenager wasn't close to completion. Haru aimed to fix this.

Haru groaned, "Yuujin please kiss me." Haru knew kissing was his boyfriend's weakness.

The two locked tongues. The kiss between them was wet and sloppy. Nonetheless, Yuujin's tongue dominated Haru's due to the smaller male too occupied with impaling himself on Yuujin's cock.

"Haru I think I'm going to come." Yuujin groaned.

Haru couldn't reply. He was too lost in the heat of the moment and released himself on his and Yuujin's stomachs. At that moment, Haru's canal squeezed Yuujin's cock in a vice like grip. The closeness of their bodies, the kissing, added with the tightness of Haru's heat pushed Yuujin over his limits. Yuujin loudly moaned his lover's name as he emptied himself deep inside Haru.

The couple tried regaining their breath. Both looked at each other. Blue eyes met green eyes. Nothing else mattered in the world to them at that moment but each other.

Yuujin broke the silence. "So, I guess we are no longer virgins."

"I guess so." Haru giggled.

"We should probably clean up," Yuujin stated.

Haru nodded his head in agreement. He slowly removed himself from Yuujin's shaft. Haru felt a little weird without having Yuujin in him. He wondered if that was normal for someone's first experience. Yuujin pulled some tissue's from Haru's nightstand. He used the tissues to clean up their chests, his organ, and Haru's cheeks and hole.

Yuujin left the bed momentarily to throw the used tissues in the trash can. He went back to the bed and pulled Haru close to him.

"How are you feeling by the way?" Yuujin quietly asked

"I'm doing alright, just feel a little sore." Haru hazily responded

"Sore?" Yuujin looked apologetic.

"No, it's okay, I enjoyed it. Did you?"

Yuujin nodded yes. "So where did you learn all that stuff?" Yuujin changed the subject.

Haru face flushed. "Internet."

"Wow, that's so naughty of you Haru." Yuujin said while nuzzling his cheek with Haru's. "Did you think of me while you were watching?" Yuujin huskily asked.

"Yeah." Haru said with his face changing pink. "Yuujin I have a question."

"Yes?" Yuujin replied.

"Do you think anything has changed between us?" Haru asked.

"No not really. I mean my feelings towards you are the same as before, the only thing that changed between us is we have a new way to express our love for each other." Yuujin stated with a warm small smile.

"I feel the same way." Haru smiled back.

Yuujin yawned and Haru commented on it. "I think someone is ready for bed."

"Yeah, what about you?" Yuujin somewhat knew the answer to that since he saw that Haru's eyelids were shifting between being open and closed. Haru just nodded to Yuujin's question. Haru rested his head down on Yuujin's chest.

Haru quietly said, "one last thing before bed. Happy anniversary Yuujin."

Yuujin sleepily responded, "happy anniversary Haru." And with that the couple drifted away to sleep holding onto each other.

AN: Hoped you liked it. Let me know if you want to see more in the future.
