??What the fuck? Not wishing to choose only one over another? Can we at least be honest here author. Here I have a much better synopsis for you.
"Mukai Noaya has lusted over Saki Saki since grade school, and when she finally accepts her place in his personal harem, he's at his happiest. But one day, a cute girl name Minase Nagisa confesses she to him, that she likes ffm threesome. Not wishing to let her down, Naoya happily accepts her into his harem, which now has 2 chicks. What will become of this circle of thottery that challenges common sense itself?"
