I kind of found the bit where she was just trying on different underwear kind of interesting.
At the point where he decided to 'help' her, I can't really blame him for losing control.
Well, he said he wanted his old sister back, and by that end I think he did. Except, well, she really fawns over him now, which I'd say is a good thing.
A scene of her with her usual black hair would have been nice though, I have to say.
He liked her the way she was before she started being influenced by her kogal friends, and his favourite panties were the cute ones. This guy has good taste!
So, he got his "original" sister back, but was it worth becoming the target of neighborhood gossip, especially on Page 22 when she revealed she's wearing (*cough-cough*) his favorite style of underwear? You Tell Us, "Onii" ... you Tell Us.
Cute story and girl.
But I start to wonder if they added step-sister. Most of the work are blood related sister. This time not. Not that is a problem tho. It's the more legal way.
Ah a legalish Incest (I do enjoy regular incest but step bro/sis is just better I think) release and kogal to boot! Abe my boy I think you just got a follow for this well done work.
