I moved to Tokyo to prepare for my university entrance exams, but since the exam date was still far off, I decided to stay with relatives. Living there were my cousins, Mitsuki and Aoi, who were always hanging around me. During my study breaks, they kept teasing me relentlessly. Whenever I tried to focus, their accidental upskirts would catch my eye, breaking my concentration. To make matters worse, they mischievously started touching my crotch, leaving me constantly on edge. I didn't know what to do—I was completely overwhelmed.
