As a ronin preparing for entrance exams, I've already failed three times. This year, I absolutely must pass. But there's one obstacle constantly getting in my way—my unemployed sister. She spends her mornings drunk, constantly interrupting my studies. Still, no matter how much she messes with me, I'm determined to pass this year! Huh, speaking of her, I hear her footsteps approaching my room. As usual, she's half-naked and slovenly, coming here to ruin my concentration again. Chugging shochu while grinding her hips, she performs what she claims is a "prayer for my success"—some kind of bizarre new martial art?! The drunker she gets, the hornier she becomes. Oh Goddess of the pussy! I'll creampie you—please, grant me success on this exam!!
