SPOILER!
This was both super miserable and super hot.
Why did they have to make her a cute chuunibyou only to then spoil that cute part of her personality?
NTR usually make me cum the hardest when the girl looks like she was manufactured for the sole purpose of getting fucked (hence the term NTRbody), but here she's actually cute and weird and then when she's 完落ち'd she just drops the chuunibyou act and talks normally, turning her into a generic hentai slut.
I don't really get why so many NTR works become hotter once you're actually invested in the characters. The other girl in this actually feels like a reasonable person, feeling regret at letting the cucks girlfriend become a generic slut and leaving him. All until the final track where she gets 'punished' and fucked so hard by the bull she completely 180s on all of it and gives in to the cock.
I simply don't get it. It's soul-crushing, but I came so hard.
