Idol students who didn't attend enough classes were raped and gang-raped by an older male teacher. (Rainbow Kumi, MIDV-450)

For idol students with insufficient attendance, the teacher presents a lewd option: to avoid failing a grade... begin with being seen naked and subjected to on-campus rape. They shove sticky, engorged penises deep into the student's throat, enjoying intense oral sex and foreplay with a middle-aged man's tongue licking her! Her frail body nearly collapses during the intense sex! Even the principal joins in, escalating the filthy adult group activity! What fate awaits the idol students corrupted by pleasure...?
