3 Be a good person!

"Uwaaa!" 

Watching the tragedy that happened before him, the other teacher, who wasn't bitten by Teshima, quickly ran away in panic, leaving all of them. 

Meanwhile, Kyoko no longer cared that Isao held her breasts, and she stared at this scene in fear as she realized how dangerous their situation would be. 

Teshima bit the male teacher mercilessly. 

Kyoko was about to scream, but her lips were covered by a large hand. 

"Sensei, don't scream." 

Kyoko was startled, and she only realized that she was still in the ambiguous position, being hugged by her student as he lightly touched her breasts. However, she thought this was an accident as she knew he was trying to protect her from Teshima. Nevertheless, the mix of fear and heat that came from Isao's strong and manly body made her feel strange. 

Kyoko knew she shouldn't react this way, but she was wet.

"It seems that it reacts by sound. If we keep quiet, then they won't notice us.' 

Hearing his whisper, Kyoko was surprised, but she followed his words obediently and didn't say anything, letting her mature body be hugged by a young man, who was also her student. She tried to calm down, especially when she was an adult, yet she couldn't since this position made her body react to something that she didn't wish to. Moreover, suddenly, she could feel something huge, hot stuck between her soft, big buttocks, causing her to be startled before she looked at him with an admonished gaze as if trying to scold him. 

"Sorry, Sensei." Isao looked awkwardly at Kyoko as he apologized. As his body grew stronger due to the DNA of animals that had been absorbed into his body, he felt like it was so easy for him to go into the heat. Moreover, he was young and strong. Lastly, Kyoko's mature and charming body was so unbearable! 

That huge ass, wrapped in a tight skirt, was pressed against his nether region. 

Frankly, he shouldn't have reacted, especially with the current situation, yet what could he do?

Moreover, her admonished gaze was tinted with a cute blush on her face, making his erection harder. 

Yet, in such a situation, the two of them were in silence, and they saw how the teacher, who was bitten by Teshima, became similar to Teshima and the man outside the gate. 

However, as Isao had said, when they stayed quiet, it seemed like... Teshima and this male teacher ignored them, and they didn't seem to see them. Instead, their eyes were attracted to the noise that was made in the school. 

Yet, at the same time, Isao knew they planned to ravage everyone in this school! 

When that happened, then they would turn everyone into a similar existence, and by then...

"..."

While Isao was fine with following the original plot, he also felt that it might be better to make his development easier, so after learning the result of letting those two into the school, he made his decision. 

"Sensei, stay here for a while." 

"A-Are you going to leave me? Please don't leave me!" 

Kyoko held Isao tightly in panic. Even if Isao pressed his erection on her huge ass, it was a hundred times better than being bitten by those things and turned into something that wasn't a human! 

Yes, she knew she was older, and she was a teacher who should lead him, yet in this situation, there was no one she could rely on except for Isao!

If Isao left, then...

When she thought of this, she looked at Isao's erection, which was impossible to ignore from his pants. Her body became hotter, and she knew that there was only one way to make him stay with her, but Isao said, "Calm down. I will not leave you, but if we let them, they might bite everyone at school, and by then..." 

Even if he didn't continue, Kyoko knew that if they let those two enter the school, then everyone would be in danger, but... but... 

"Stay here. As long as you stay quiet, you will be fine." 

Hearing his comfort, Kyoko looked at Isao with misty eyes. "Be careful." When she said those words, whether she did it subconsciously or not, she put her hand against his erection and lightly grabbed it before she let him go as if it was an accident. 

"....." 

Isao looked at Kyoko, whose face was so red, and made up his mind to come back alive. 

Still, what could he do?

If it was before, when he was still a normal human, this situation might be difficult. The only thing he could do was beat up the two male teachers, and this was the fastest solution, but then, as no one knew what was happening, he would be pointed at and become a criminal in everyone's eyes. 

While he didn't care, as everyone would be bitten and die anyway, he had decided to do a good thing from now on, but even if he did so, he wanted to do it smartly so no one could pick a fault at him. 

So, at this moment, he quietly walked behind Teshima and the male teacher, who had turned into something that wasn't a human. As expected, as long as he didn't let out a voice and just walked quietly, they didn't notice him. Moreover, as he had removed his shoes and even changed the soles of his feet to be similar to a cat's paws, his movement was so quiet that it was almost impossible to pick up a sound from him. 

By then, he had picked up the male teacher and thrown him outside the gate before he did something similar to Teshima. 

With this, all three strange beings were outside the gate, but they didn't seem to give up on entering the school. They continued banging and biting the gate, trying to force themselves inside. 

While they might be powerful, Isao knew that they weren't strong enough to break this gate unless there were more of them. Nevertheless, it might be strange of him to be able to do this, as throwing a human outside the gate wasn't an easy feat, especially when the male teacher and Teshima weren't light.

However, he got the DNA of the Tosa dog, a specially-bred type of dog for fighting and one of the strongest dogs in the world. Moreover, it was said that this type of dog could pull up something weighing more than 3,000 pounds!

As those muscles and power transform into something for a human, what would happen?

While Isao didn't think he could throw a road roller into his opponent, he knew that he had become so strong that he might easily win the World's Strongest Man competition. Moreover, while the gate was relatively high, the wall on the side was short, so it was easy for him to throw the two out. 

However, the most important thing was that he was able to save everyone in this school and save himself from various troubles that he might encounter if everyone in the whole school turned those "things." 

As he succeeded, he turned and made a V sign to Kyoko, who was waiting for him with a bright smile.

Watching this, Kyoko looked at him with relief and a happy yet helpless expression. 

Nevertheless, Isao felt that doing something good was great, and naturally, as he had decided to become a good person, he was going to uphold his promise to Teshima by taking care of Kyoko well~!
