In response to rising cancer rates among youth, a mixed-gender anal health examination was conducted in cooperation with government research. However, female students naturally felt resistance toward rectal and anal exams. To ease their anxiety, newly appointed English teacher Honoka Shiina volunteered to lead the examinations. Gently palpating lymph nodes, the squatting position with buttocks exposed exuded a subtly erotic atmosphere. Checking lower back, hips, body temperature, and specifically for lumps, all results came back normal, bringing relief. Next came the anal examination. When bleeding was detected, students felt embarrassed and tried to cover themselves, but any resistance was met with forceful continuation of the exam. The teacher carefully inspected for polyps and sphincter abnormalities, then used a special instrument to examine deeper areas. Students gasped in surprise: "W-what is this...?" "Uhh... ahh... what's happening...?" Then came the suggestion: "Shall we check the birth canal at the same time?" leading to simultaneous dual-organ examination, followed by re-examination with another specialized device adjusting angles. During the process, students were instructed: "Move your hips to see if you feel any discomfort yourself? Very good!" Students nervously asked, "A-are my organs really okay...?" to which Ms. Shiina reassuringly replied, "Yes, you're fine." Finally, medication was injected deep into the uterus to conclude the exam. Everyone, did watching Ms. Shiina's examination ease your worries? ※ Note: This title starring Kanna Shirai does not include anal sex.
