I wonder how many times the older sister stole away a guy without the younger knowing. Older sister is a beauty, hard not to be seduced by her.

Not only got she betrayed by her boyfriend, but also by her own sister. That's rough.

BF has no backbone and appreciation. Cutie girlfriend blowing him and asking him how to make it better. That kind of girl is a keeper and yet her fell for some bimbo with huge knockers. Disappointing but sadly the art was very hot.

@Kaisigmu
And what's so disappointing about this manga? I seriously don't understand where all these comments condemning the sister and boyfriend are coming from. This manga has a MALE:NETORARE tag that makes it pretty obvious what the plot is going to be.(The guy will be stolen from the girl) And yet for some reason people still read this manga, get exactly what's in the description, and then complain in the comments about the fact that the plot is not to their liking.

If you don't like male:netorare so much, why are you reading it in the first place?

It's crazy how many people in the comments hate the guy, where is this same energy in regular Netorare towards the girl when she's cheating ?
The Gender Bias and Hypocrisy towards men in Netorare never cease to amaze me. Anyways though Reverse Netorare is difficult to find these days and I sure as well enjoy them better than regular Netorare considering how Scarce they are, and to be perfectly honest I rather when guys are stolen so reading this was truly something.
