Not sure how I want this to end. I kind of want the scumbag siblings to end up miserable because one is turned on by being the 'other woman', while the other just doesn't care about his partner.
At the same time I hope this goes the hentai plot route with the GF trying to have a sex battle with the sister to win over her BF, before all three decide they love each other and end up in a three way relationship.
Anyway, this post clearly shows I'm reading this for the plot, unlike you other degenerates.
