School Stud: Scrub girls showers
From Create Your Own Story
Coach puts you to work on the girls showers all day. You scrub the walls with a bucket and a brush. You have to fill the bucket with water and detergent. You can't believe how much gunk there is on these grimy walls. Your muscles start to ache. Hour after hour passes by and you realize that your day is gone and your dick goes limp. Damn, you're a sad mess.
The end.
