Teacher Ren finds her student crouching on the street at night. She brings him home to help, only to learn he was drugged by friends and can't stop being erect even after ejaculating. Seeing her beautiful, white breasts and curvy body, the student loses control. He forces her into fellatio and deep creampie sex. His "monster cock" stays hard all night, relentlessly attacking until she is completely spent from the continuous assault.
