You inherit some mountain land from your dad, and lo and behold you find a pair of oppai loli twins using a shed in the mountains as their secret base. Naturally, "cohabitation" ensues as you spend your summer days hanging out with these twins, where you get to enjoy a variety of pixel animated scenes featuring a couple of outfit variations. There really isn't much in the way of "gameplay," and while the game is described as a touching SLG, there really aren't much reactions from touching and feeling. There also aren't as many scenes as you'd think, since between the twins they're basically the same aside from the hairstyle and the fact that one of them is *ever* so slightly bustier than the other. It's not the most engaging game out there but at the very least the art and animation is nice so it is, at least in my opinion, very enjoyable.
