No Glory

Unisex toilets were introduced in the school. After the study groups, you have to go to the loo again and use one of the now almost completely deserted toilets. You see the school's most popular girl, the blind beauty Sarah, enter in front of you. You go into one of the cubicles and, to your surprise, there is a hole at waist height through which you can see Sarah in the neighbouring cubicle. Luckily she can't see you, because her cubicle is brightly lit while yours is dimly lit. Are you going to watch her or do you have something else in mind?
