A high school girl wearing a powerful electric massager challenges herself to a game of Twister! Can you last 15 minutes peeing? This time's challenger is Haruka from the brass band. After she gulps down a drink containing a diuretic, a vibrator (with super vibrations and bumps) is firmly fixed to her with a special belt. Her beautiful legs are exposed, her left foot is blue and her right hand is red -- if she starts to move her hips like that, the vibrator will hit her clitoris directly! "... No, I'm going to come!" No matter how hard she tries to hold it in, she can't avoid the end. Her beautiful body has been enduring the pleasure, and no matter what the staff does, she can't resist. With the electric vibrator on, they lick her lips and ears, and even her beautiful big breasts! When I ejaculated inside her tight pussy, she said "That's gross...!" Even after cumming, I just keep pounding away!
