Koushien Ha Oitoite (“Koshien As An Afterthought”) [English], by Shirono Jia
Don’t run away. This is vanilla.
I’m making the precision, because I was totally convinced it would end up badly.
Force of habit.
When a highschool boy on a sports team is cheered on by a smiling girl from the sides, it doesn’t bide well. I was already picturing the girl blackmailed by an evil principal (“you don’t want your boyfriend expelled, right?”), or raped (by jealous teammates), or mindbroken (by a horny pig-coach with a big dick and disgustingly good skill at twising girls’ spirit), shit like that always happens.
But… no, nothing of that, vanilla. YISS!!!
There’s pretty good art, bearable censorship (a few black bars, this is nothing nowadays), a lovely naughty proactive female MC, enjoy! ^_^
And thanks to Ingloo, from Scans For Humanity, for this one!
By the same artist, I also share Gaman Shite Hoshigatte and Yahari Ore Wa Isshiki Iroha No Shoujou De Odoritsuzukeru.

Sweet, to the point, reallistic and for added bonus the girl is aggressive :3
Thanks for the share!
Dialogue during sexy fun time might suggest on another occasion that Senpai is merely an Assertive Girl who’s sexually active and is more attracted to her underclassman’s dick than to him. But it’s a vanilla-flavored work this time around, so I’ll let that slide. And so, with virtually every cheer from the sidelines or encouraging call-out by Mizuno-senpai, there is one dominant thought resonating in the minds of the rest of the team towards male protag-kun:

yeah, that “yours really is amazing” line of page 8 suggest that she might be aquainted with a couple of others that provide her service…
Seems that we need to be the ones finding non NTR ones for you, Oliver. You need them, a lot.
Hentai-aid, is it in you (or her)?
