As the semester neared its end, even Kaede and Suzu, who had excellent grades, were focusing on revision.
As for Sagiri and Elf, who didn't attend school... they sent photos every day. Rin Ito went over every other day to swap out their plugs for a slightly larger size. For the rest of the time, Rin Ito was mostly at home drawing, as the deadlines for the manuscripts had to be met, and he couldn't trouble Orie like Shigure did.
On the last weekend before finals, Rin Ito finished his manuscript and stretched deeply in front of the computer. Thanks to his previous 'scouting,' Rin Ito had an inexhaustible supply of material in his mind; the storyboards would surface immediately with just a brief recall.
As Rin Ito stepped out of his room, he heard Nanami's voice, sounding close to a breakdown, coming from the room next door.
"Mashiro, this problem should be..."
Rin Ito quietly walked up to their door, knocked, and then pushed it open. He saw the nearly broken Nanami and the composed Mashiro sitting side by side at the desk. The table in front of them held textbooks and practice books, not drawing paper.
That's right, Nanami was tutoring Mashiro.
But the results... Why! Why are Mashiro's grades so bad! Why can't Mashiro learn anything at allllllllll!!!! His mind was trembling!!!
Judging by the expression on Nanami's face, which looked on the verge of a breakdown, the tutoring wasn't going well. Nanami sniffled and looked at Rin Ito. The look of wanting to cry made Rin Ito feel... like laughing. Nanami was now truly experiencing what it felt like for a mother to help her child with homework.
Although Mashiro didn't need grades to prove herself, she was still a student, and she should try her best in exams. If not top scores, at least... at least she should pass, right!? At least she shouldn't have to attend remedial classes during the school holidays because she failed, right? Nanami had voice acting classes during the holidays and wouldn't have time to accompany her to remedial classes!
Seeing Rin Ito appear at the door, Mashiro quickly rushed up to him, squatted down, and reached out to touch his waist.
"Stop, stop, stop, stop..." Rin Ito quickly held Mashiro's hands. Mashiro was so cute that he wouldn't get tired of her even after a year of 'having her,' but Mashiro was clearly trying to use this method to escape studying.
Mashiro had a phenomenal memory; even problems she didn't know how to solve could be memorized simply by seeing them once. And she didn't memorize the solution steps but rather memorized the problem and the answer as a single drawing. If a normal person memorized the solution to a problem, they could apply the principle to similar problems, but Mashiro couldn't solve it if the problem wasn't exactly the same.
However, Mashiro wasn't stupid. She just put most of her energy into drawing and a small amount into sex. If she dedicated just a small portion of her energy to studying, her grades would certainly be fine thanks to her memory. The energy dedicated to drawing couldn't be touched, so he had to find a way to temporarily divert Mashiro's sexual energy towards studying. But ordinary lecturing wouldn't work.
After a moment of consideration, Rin Ito sat on the chair and picked up Mashiro, letting her sit on his lap. His hands slipped under her shirt and gently kneaded her breasts, which perfectly fit in his hands. However, Rin Ito didn't deliberately tease her, only gently massaged.
"Do you like this feeling?"
"Mhm." Mashiro nodded.
"But... if you fail the exam, you'll have to attend remedial classes during the holidays."
"So?" Mashiro asked, confused. Remedial classes were just like regular school; what was the big deal?
"In that case, during the holidays, when Nanami and I stay up all night, fill both her openings until she comes so hard she sprays all over the floor, you'll have to go to bed early because you have class. When we have a party during the holidays, you'll have to stay home because you have class... Is that okay?"
Mashiro hadn't said anything yet, but Nanami's face was already burning red... We're encouraging her to study; why bring me into this! Although Nanami's entire body had been thoroughly explored, her sense of shame was the same as before.
"And... if Ms. Chihiro finds out your grades are too poor and doesn't let you stay here anymore, you'll have far fewer chances to attend parties."
"...No."
Hearing this, Mashiro finally spoke, shaking her head repeatedly. It was absolutely unacceptable to have a party without her!
"So, you have to study hard. After you revise, you can join the parties."
"You must have done similar problems in this practice book, Mashiro. How about this... for every correct problem you solve today, I'll reward you with 5 minutes of time?"
Mashiro hesitated for a moment, then nodded, and lightly rubbed her soft butt against him. Even through his pants, Rin Ito could distinctly feel the softness of Mashiro's buttocks.
"Put it in," Mashiro paused. "Otherwise, I can't concentrate."
"..."
Rin Ito and Nanami were speechless... What the hell is 'concentrating better with it in'!?
Wouldn't that be a distraction? Although Rin Ito doubted whether this would make her concentrate or distract her, Rin Ito had similar experiences before, like doing homework while watching TV. So, it made perfect sense for Mashiro to be able to do homework while being fucked!
After a slight hesitation, Rin Ito nodded. "I'll let you try first. If you get two problems wrong in a row, we stop, got it?"
"Mhm."
Mashiro was too lazy to wear panties when at home; often, a long-sleeved shirt or a blouse was all she wore. Rin Ito only needed to pull out his shaft to directly reach the depths of Mashiro's body.
"Alright, start working on the problems now."
Rin Ito held Mashiro like this, watching her do her problems. Seeing Mashiro's serious demeanor, Nanami breathed a sigh of relief... Although Mashiro occasionally wiggled her hips, she seemed genuinely focused. If Mashiro maintained this state, getting a passing grade should be no problem.
But still... Concentrating better this way is just too weird! Is his dick some kind of 'Concentration-Injecting Stick'!? That only requires insertion to focus her mind!? Nanami suppressed the urge to complain and didn't disturb Mashiro.
Nanami had only heard that men become smarter when they want to have sex, but Mashiro... does Mashiro also become smarter when she wants to have sex? No, Mashiro wasn't becoming smarter; she simply hadn't focused on studying before. Now that the 'Concentration-Injecting Stick' had injected focus, she could finally take it seriously.
Nanami only had to suppress the urge to complain, but Rin Ito had a much harder time. Rin Ito had to suppress the urge to thrust his hips. Although Mashiro's tender, wet, smooth body felt comfortable even when stationary, the more comfortable it felt, the more he wanted to move, the more he wanted to forcefully thrust into the 'baby room' and fill her up.
Although it was tough to hold back, seeing Mashiro write down the answers in the practice book one stroke at a time, Rin Ito felt somewhat relieved. It was hard work, but at least it was working!
