Sexy blonde schoolgirl is with her teacher in a room. He gives her cups of water to drink and then after a while, he has her sit on a stool and he ties her hands together. The water she drank works in her system and her bladder becomes full.
She is desperate to pee but she can not do much because her hands are literally tied. After a lot of squirming, she pees on the stool and wets her panties and the floor. The teacher unties her hands.
