There’s no scenario here. For some reason, three Love Live idols offer one of their fans a private thanking session, and the fan finds himself greeted by the three girls disguised as nekomimi and telling they want to do ecchi things.
Hey, why not! ¯\_(ツ)_/¯
The drawings are quice pleasant, with only thin censorship bars over the girls. I hope you can enjoy your read, and thanks to Nakuke for this release!
Side note, I grayscaled the images, they had a very faint reddish taint.
