MMUS-041 The absolute tease sisters who stop just short of the line Mitsuki Nagisa and Aoi Suzuki

For university entrance exams, I moved to Tokyo and stayed at a relative's house for a while. There's not much time left until the exam. I need to push myself to the limit, but the problem is my cousins Mitsuki and Aoi who live in the same house. These sisters always interfere when I'm studying. I need to concentrate, but their panty shots keep flashing before my eyes. Soon they even started touching my crotch, and now I'm completely at their mercy with this teasing that stops just short of the line. Ahh, what should I do!
