She appears timid and afraid

You imagine the nurse sitting in her office after school, only a few hundred feet away from where you wait with bated breath in the tech lab. You know that Mrs. Pill--no, she asked you to call her Sarah after your unexpectedly sexy encounter a few months ago--secretly looks at porn at school. Is she horny right now? you wonder. Just the thought of Sarah Halperin fingering herself makes you hard; what would it be like to actually fuck the nymph?!
