Very nice. Reminds me of a pixiv series that I've been looking for for a while where a magical girl gets raped by her classmates at school. That one was also 3d renders, but the classmates didn't know she was a magical girl and I think she had animal ears or something.
Either way, this is really good. Thanks for posting!

Sad that she shifted to posting all the good stuff at Fanbox instead of at Pixiv or as survey rewards like before
