This reminds me of Yurika no Campus Life, it has a similar basic premise: dumbass straight female MC learns to become a womanizer for her own benefit, hilarity ensues.
It's bi at best and at worst it's just a straight woman being forced to have sex with women (she still has a ton of male lovers off-screen while all this "seducing" going) to avoid getting her head chop off.
If that's what get your rock off go ahead, it's a nah from me.
