Rape/ganging up on her: You're applying logic to a manga, especially a smut one? First of all, I don't condone rape. Second, while not every smut manga has rape and/or begins its story this way like this work, rape is a common feature.
So small reminder: FMC will live together with her childhood friends (Twins) whose even work in the same company! She had a crush on these two and these two had nearly raped her... is it right?!
Damn the art and the rape are fucking hot, I'm a man and faceless classic old man rape doesn't hold a candle compared to this in terms of making me horny
