I do not think it's really a netorare. In this comic the protagonist is the blacks haired guy, not the blonde one. The bully is what usually ends up being the one to netorare other guy, in this case the blonde one is the bully who hit the black haired guy. Sorry i am italian and i not write very well.
I think this H-manga is a netori, not a netorare. I realy hate netorare, but in this case fuck you blonde boy, you hit me, i fuck you girl! And i fap on you face.
End ofc on the dlsite, the tag say
制服 学校/学園 パラレル "寝取り" 強制/無理矢理
In this case "寝取り" if you use the translated is Netori. So is not a netorare.
