"In the trial rehearsal," "locked in the toilet," "made to drink diuretics," etc. A private tutor who encourages his female high school student to feel the urge to urinate. The girl is not allowed to go to the toilet and fidgets... And when she reaches the limit of holding it in, the man suddenly changes! He slides down her panties and forcefully inserts a large erection! Stimulated in her private parts, she has a massive incontinence with splashing sounds! He makes the whole house covered in embarrassing juices and makes her climax repeatedly!!
