This is a really sad attempt at keeping the story away from being tagged hentai. One thing for sure, there are much more psychological titles out there that's far out of reach of anyone not of legal age.
When we think of incest, most already jump at it and scream to the top of their lungs. Being as incest already comes with psychological theme, the author only adds more to it. From that point on, there will be more cruel play on intercourse overstepping its boundary. School Days' ending should not be ruled out.
The potential is there if you like drama, rape, and whatnot that goes beyond the list. The worst and best 'human' drama is when sex (rape, affair) comes into play.
To make it short, this is NTR censored for those whose blood rises at cheap panty flashes. This is not even worth recommending.
I just want to point out that girl who has sex with a stranger. That's bullshit for expressing one's love. I'm sure a lot of people expresses there love through a lot of ways like defecating in a bowl or some weird arse stuff but this is fucked up. to make it even worse, this is her first time too. it's either this girl lives with a broken family. she probably witness some batshit happenings. Maybe she saw her mom or dad with strangers and when she asks the parents why they're hugging (you-know-what) with strangers other than each other, the parents probably told her it's because they're expressing love to the person they love by having hot sweaty perverse u-know-what with strangers. she probably later found out it was all a lie but it was already too late. she was already way traumatized for any right reasoning in life. if the author doesn't even touch on her side of the story, then that would be the lamest turd ever.
i rest my case. there is not a normal young lady who drags a lover to a place and initiate sex with a stranger and while being fuck, moans and groans and tells the lover: "oh-yeahhhh, i am doing this cus i love you. i am having a stranger take my virginity because i love you. i am taking 2 at once... i am now trying to take 5 at once. i am now dripping wet BECAUSE I LOVE YOU! while losing her self in an orgasmic explosion.
i'll add that the story strays from 'aki-sora' like others have stated.
well, there goes my trolling. i registered just to get that off my chest.i'll be back for more.
