There are somewhat inappropriate innuendoes in this chapter, it's not horrible but if you are really sensitive to that stuff don't read I guess... yea
it's the joke material of immature middle schoolers

Hinata tends to say things that you can take very, very wrong, and it's usually around Kageyama

The two were once playing a video game involving rubber balls or something (idk man) and Hinata said

"I feel like we should be able to change the colors of our balls"

And Kageyama just lost it

Other examples are

"Oooh I get to be on top now!"
"Can I ride this time?"
"Just stick it in already!"
"gAH it's so big!"

Oof it's been a while since I've updated
