The first 5 chapters of the game has 3 full blown sex scenes, one with a major character (the triplets mom) and two with recurring characters who are relevant to the story. That's not including 7 additional scenes that include third base or some form of oral sex. That's not including all of the other lewd occurrences, such as dark content including spanking, belting, baths, etc. ← Again, all of which happen with characters who are important, or major in the story.
You have a weird definition of blueballing.
But yes, there is a full fledged sex scene in Ch6 as well as more oral sex with yet another story-relevant girl and even a masturbation scene featuring a major character. Won't say more for fear of spoiling. There is even a chance of pregnancy in this one.
With main LI's pretty much everyone means the triplets, the rest are side characters, if these side girls play a role in the story and you see them from time to time doesn't change that.
The triplets mom sure as hell isn't a main LI...she is dead and even before that, she was a one night stand.
Also sorry, but dream sex is the worst kind of nsfw scenes, can completely forgo these, even side girls are better.
So what scenes do we have ?
One with the triplets mom, where she is alive, that scene is good.
The one with the crazy waitress, no thanks, i ignore her.
The forced bs with the mother of the dead boy, even more so, no thanks. I would ignore her completely if i could.
The cashier girl we met once and barely spoke to before she jumps the MC, also no thanks.
Necro dreams of a dead one night stand, fuck no...
Some foreplay with Olivia, was nice.
Did i forget something ?
I didn't play since the alpha release (first part) of the last update and it's been a while.
