I am that male friend in the harem story

Madness. 

This was probably how they described their night. 

Onodera thought the beginning would be painful and even rough, yet unexpectedly, it was so comfortable and pleasant. His 19 cm white marker was intimidating after all, and it was also their first time, but even so, he made her comfortable; crying with happiness, she became a woman.

Last night, Ishigami became a teacher; he was so gentle, teaching her knowledge that she never knew. 

As a student, Onodera was also eager to learn this knowledge and kept begging happily for him to teach her with a sweet voice. Unfortunately, instead of getting smarter, she became even more idiotic as her language became limited, and the words that came out of her lips were just "Sugoi!" "Iku!" "Yamete!" 

Yes, even if Ishigami was gentle, he was also strict, so Onodera was thoroughly worn out after last night's study session. 

Fortunately, the hotel had a service where they could send food to their room, so the two of them ate in the room, washing up before they slept soundly. 

Well, Ishigami could teach Onodera more, but he knew well this was Onodera's first time, so she needed time. At the same time, due to the system, he could quickly master his new knowledge even if he just lost his first time yesterday, so even if it was their first time, the two of them didn't fumble awkwardly and hurt each other due to their inexperience. 

Instead, there was no doubt this first experience was something that the two always remembered. 

"You were so amazing..." Onodera said with a hoarse voice. 

The two washed themselves in the morning before they rested in the bathtub together. 

Using that chance, Onodera sat between his legs and leaned on him, rubbing her face lovingly like a kitten on her boyfriend as she kept praising him, which made him slightly overwhelmed, but he didn't hate her overflowing intimate exchange since he also understood how emotional she was and being praised on that area was nice to hear since what kind of a man who hated the praise of his woman who told him that he had given her a pleasure? 

"When I recover, let's do it again."

At that moment, Onodera felt that her lower body was sore and exhausted, and she believed that she would walk while limping later, but even so, she couldn't forget the pleasant joy that came from their first time. 

It was so unbelievably great! 

"Yeah, you should sleep later." 

Kissing her hair from behind, Ishigami hugged her softly as he played with her breasts. Frankly, they were small, smaller than he had thought, and if there was a reason why they appeared bigger, it was because she wore a breast enhancement bra, which made her breasts more prominent than they were. 

If Tsubame was a cantaloupe, then Onodera would be an orange. 

Her two oranges might appear sour, but when he sucked them, they were sweet, and they were rather sensitive, which made Onodera's reaction something that he loved to see. 

"I don't want to leave you..." 

There was still time before they checked up, which was great, and it was fortunate that they didn't wake up late, so they had a lot of time to be together. However, as breakfast time for the hotel was almost over, they wanted to eat something before they left, but even so, Onodera was reluctant to part away. 

"Me too." 

Ishigami also didn't want to part away since it felt so comfortable to hug her in his arms. 

"But your parents might get worried about you." 

"....." 

Onodera knew that she had made an excuse by saying that she would be sleeping at her friend's house, and she also had told her parents that she would go home on Sunday, so if she stayed with her boyfriend for a longer time, she knew that her parents would be suspicious. 

Still—

"Let's go back after this." 

When Onodera said so, Ishigami's body stiffened since she again held his white marker. 

"It's as lively as ever." 

His 19 cm white marker had always been straight and impressive. 

In the beginning, she was a little afraid of it, but just one night, she loved it, and when they slept, she never let it go, holding it in her hand like the most precious treasure. 

Rubbing, stroking, caressing, Onodera held the 19 cm white marker in a variety of ways, trying to search for the most comfortable ways to hold it, but as she kept shaking it, the white ink spurted out from the marker and stained her beautiful face. Some of the ink even entered her mouth, but instead of being troubled, she tried to lick it, tasting it, which she thought was kind of nice. 

Fortunately, this ink was organic, so it was safe to consume. 

"It tasted a little strange, but strangely enough, it was nice." 

The taste was quite nice, she thought, so she sucked the tip of the white marker curiously. 

Yet, watching his girlfriend, whose face was stained due to the white ink and her sunken cheeks due to her sucking his white marker, Ishigami thought that his girlfriend was dirty. 

Still, while there were many incidents in the bathroom, the two weren't late for the breakfast session and sat together closely, eating breakfast as their study session had taken much of their stamina. They might be young, and their bodies were brimming with vitality, but even so, they needed food to replenish their energy, especially Ishigami, who needed to work hard to make the white ink that his girlfriend loved so much. 

'I need to work out a little harder.' 

If his physical ability was at level one, he knew that it would be impossible to produce white ink so many times, but fortunately, his physical ability was at level two. Still, while he was okay, he was a little worn out and hungry.

Well, it wasn't that Onodera caused him trouble since even if her stamina was good, considering she was a member of a sports club, she was a beginner and a newbie. More importantly, under his relentless attack, she could only succumb. 

However, Onodera loved to play with his 19 cm white marker and drank the white ink even if it wasn't supposed to be consumed. Ishigami also didn't want to admit defeat, so even if she tried to drink his white ink, he kept working harder to meet her demand. 

"Come on. Eat first." 

"Feed me..." 

Onodera asked feebly like a baby. 

"It can't be helped." 

Under his care, Onodera smiled happily, and she realized that many were staring at them. No, it should be that they stared at her boyfriend. While she had realized it before, she also had to admit that he had become more handsome, and more importantly, his skill, energy, and 19 cm were impressive. 

Onodera knew that she was blessed, and because of that, she was a little smug, leaning on him happily, watching everyone, and showing them that this young man that everyone stared at was her boyfriend. 

Regardless, after they ate, it was their time to part. 

Ishigami didn't follow Onodera's home since he had somewhere to go, and it would also be dangerous if he sent her off since there was no doubt her parents would definitely find out that she was lying. 

"Go home and take a rest." 

"Um." 

While Onodera felt reluctant, she knew that she needed to rest since she was so dead tired! 

"When I wake up, I will call you." 

"I might not answer your call since I might rest too." 

"It's fine. Just call me when you wake up." 

"Okay." Ishigami then kissed Onodera's forehead and said, "See you tomorrow." 

"See you tomorrow..." Feeling his gentleness, Onodera felt satisfied, and her heart also calmed down since she really didn't want to leave him. Still, this wouldn't be their last time to be together, and tomorrow, when the school came, she could be with him again. 

Still, she didn't want to part right away and kept hugging him until he told her that she might cause trouble to the taxi driver. 

By then, Onodera reluctantly parted away before she went home by taxi, but even so, her face was stuck on the window all the time until she couldn't see him. 

"She is like a puppy..." 

While it was rude, Ishigami couldn't help but think so, but he knew that his day wasn't over yet. At the same time, he was glad that he trained his will by working out and studying most of the time, which made him resistant to the laziness inside his heart.

"Now, one more time." 

When this day was over, Ishigami knew that he could meet a new peaceful day, so he knew that he had to work out. 

"I wonder how Kaichou and Shinomiya-senpai date is..." 

Shirogane had called him before telling him that he would go on a date with Kaguya. 

It was good, Ishigami thought, and by then, he knew that there was no need for him to worry about anything; he just focused on improving himself.

To become a better man. 

That was his goal. 

Still, even so, he wondered what to do at this moment, but he knew that his time was limited, especially when he was almost late, so when Onodera left, he hurriedly left toward his appointment place. 

As for the items he bought yesterday, he put all of them in the coin locker on the station. Fortunately, he wasn't late, but it surprised him when he saw the person he was going to today had already arrived.

Still, she wasn't alone since she saw him being approached by a male, but fortunately, unlike Tsubame before, this guy wasn't trying to be touchy. Nevertheless, he could feel the aura of desperation from this guy, which made him speechless. 

Regardless, he had never tried to pick up a woman before, and this also made him a bit curious about how it felt to pick up a random woman that he had never known before on the street. 

However, he quickly threw this idea away since he had a girlfriend.

Nevertheless, when he arrived, she quickly noticed him. 

Their eyes met each other, and she appeared to be in a daze for a while before she snorted and looked at him with a taunting expression. 

Ishigami knew well what she wanted him to do, which made him laugh, thinking that she was cute, so without hesitation, he approached her and said, "Sorry to make you wait, Senpai."

While I know that this might be a stupid question, all of you must have understood what a "white marker" is, right? 

But then, depending on the woman, the name might change, so don't get fixed on it.
