With Naruto
Soon, he heard footsteps and turned to the right to see 3 first year's making their way towards the peephole he created. A shit-eating grin started to form on his face as he identified his prey.
'Niiiiiicccccccceeeeee,' said Naruto with a satisfied expression as he got 3 targets instead of one. As they neared the hole, he let them enjoy it for a few minutes.
After he confirmed they saw something from their conversation and giddy expressions, he enacted his plan.
"Torrel," called Naruto and his slime familiar formed in his hands with a bouncy cheer.
"Yes, yes. I know you are happy to be here. Now, the time we have waited for has come. Let's get started," said Naruto and Torrel bounced from his hand to the ground.
As they planned, he slowly made his way through the grass, which shielded him from discovery and reached the peeking students.
No one could see Torrel as he was one with the grass due to his green colour as he walked through it. He reached them and turned to get one last confirmation.
Naruto nodded and Torrel split into 3 small globs and started his work. He first poured some of the glitters and paints he held on him and moved up to their pants.
Naruto wanted to spank the boys hard for trying to peek so they would shout and get caught by their own mistakes.
Torrel enlarged his slimy hand and changed it to a large fist. From the moment he has become his master's familiar, he has begun going strong.
The power and strength were unlike anything he ever experienced before. He initially only had the cloth eating power, but now he can split and maintain conscience in all three bodies.
He is aware of his surroundings to a degree and can dodge any attack thrown at him or divide and hide for the time being and reform after the threat is gone.
His increase is also noticed by his forest mates and they have started to show him respect instead of throwing him around like before.
He was so happy that he found his master and his master chose him. After all, he has so many responsibilities to perform for his master and wishes to become strong so that he can better perform them.
But now though, he has important work to do. As soon as he got the confirmation, he spanked all of them at once, hard.
"Aaaaaaahhhhhhhhhh,"
"Hhhhhaaaaaahhhhhh,"
"Ooooppppppppppaaaaaaaiiiiiii," came the 3 different screams from the 3 friends.
They already heard the kyaa and heeennnntttaaaiii comments from the changing room and their instincts started to kick in.
"Oh shit, run," said Matsuda and started sprinting. The other 2 followed him, unaware of the red liquid that started to flow from their backs.
After they reached a sparse part of the school, with so many things to hide in, they took a breather.
"What the fuck, guys. Who hit me!" Asked Motohama, rubbing at the hit spot.
"What! I got hit as well," said Motohama. They both turned to Issei.
"Guys, I was hit as well!" Said Issei but got a blank stare. As he rubbed his ass.
"Ok, see," he said, turning back. They say a red liquid falling from his back and noticed how it came along them the whole way in 3 lines.
"Issei you idiot. Why are you wearing paint on your back!" Yelled both of them. But they also saw 2 more red lines and checked to see they also have similar colours.
"Ah, you started just after the first week?" Asked a sweet voice. All of them turned to see a blonde-haired girl with a bokken.
They didn't know this one. She is taller than most of the girls and had a large bust, her kendo uniform unable to hold in. Issei immediately got a lecherous smile.
"What are you laughing at, Perv," said the girl and whipped him on his ass, hard as he was showing his friends his injury, it was accessible. Matsuda and Motohama shut in an instant.
They don't want to end up on the other side of that bokken. What they heard terrified them. They gulped nervously. They didn't see this blonde bimbo when they peeked on the kendo girls.
"What are you 3 doing at the wall on the other side of our changing rooms?" she asked in an outraged tone. The three gulped again, Issei recovering from her whipping.
"You perverts, how dare you!" She said again, this time all the other girls joining in the accusations and cries for a suitable punishment filled the area.
The blonde bimbo leading the charge. They took everything head-on like a true man, not even flinching. Though all their bodies are battered, they didn't lose the lecherous grin they had.
