The grand finale of Ippontou's original movie series is finally here! This time, a raid-style investigation inspired by London boots unfolds. The target is the lovely Minami Otsuki, whose cute buckteeth hide a mature charm. The hilarious duo, Agent 1 and Agent 2, conduct a cheating investigation under false pretenses, exposing her private life one by one. From vibrators to used condoms, adult toys appear nonstop! As punishment for the naughty Minami, she's bound with duct tape and attacked with a vibrator—no bathroom breaks, even if she needs to pee! Eventually, the sofa gets soaked in urine, so they move to the bed where she's mounted in cowgirl position and cums almost immediately. Was she innocent or guilty in the cheating investigation? Discover the truth for yourself!
