Onii-chan, Erande yo! ~Kyuuni Kawaii Mitsugo no Imouto ga Yattekite Chou Yabai~ / おにいちゃん、えらんでよ！ ～急に可愛い三つ子の妹がやってきて超ヤバい～

I .... Sekijima Kaoru, I live with three beautiful girls on the same floor.
My father's new wife has daughters, triplets.
Cohabitation with three beautiful triplets, the envy of others ... But, this is serious.
Now ... "at the same time" all three confessed to me in love.
Mika is the eldest daughter, Miki is the second, Miku is the third.
I like all three, I can not choose any one ...
"We all love Kaoru, but if you love all three, then we will not be" loved ones "anymore."
"So this is only a problem in the compatibility of bodies?"
What? What do they mean?
"Let Kaoru appreciate us ... our bodies"
Then the sisters came and surrounded me.
"Relax"
"We will take responsibility"
"Kaoru, you just need to concentrate on evaluation"
Identical triplets took off their clothes and showed me the contents.
