I am a ronin student preparing to take the university entrance exam. I have already passed the third grade, and this is the year I have to pass the exam. However, I have a point of view. My sister, who is a NEET, gets drunk in the morning and always interferes with my study. But I will definitely pass the exam this year without letting my sister's bad influence get the better of me! Oh, I hear footsteps of my sister Mai coming towards my room.... She is always coming to disturb my study in her half-naked, slovenly attire! Sis shaking her hips while stirring the shochu, a prayer for success that I've never seen or heard before! Is this a new fist technique? The drunker my sister gets, the more erotic she becomes! God of pussy! Please let me pass the test because I'm going to cum inside!
