Idol Ishida Karen is caught in an unprecedented prank storm! Whether at home, during magazine interviews, in cafes, or even in the taxi on her way home, every corner of her private life is forcibly invaded by naked, erect men in a crazy prank party! "What? What's going on?!" → They just thrust in! → "Ah…" Despite being completely bewildered, she can't help but lick and be brought to orgasm repeatedly! Without realizing it, she starts actively twisting her hips, completely becoming a born, wanton slave to pleasure! Her manager cooperates fully; her schedule, shops, interviews, and taxi rides are all meticulously planned real-life surprise sex scandals! This is the Ishida Karen we've always wanted to see… Letting your guard down is a big no-no, hehe!
