May was just a junior in high school (she had been held back a year, and was 18 then) when she first learned that she had an exhibitionist streak. She was in her school's physics 3 class, which was all seniors (and her). She had never liked the teacher, Mr. Manor, who was a little unstable, but she had never voiced this until that day. However, unfortunately for her, he caught her passing a note to her friend in class, which was quite insulting to the teacher. He got a hold of it, and, after reading it, said "Maaay! Get up here! Kids these days, no respect..."
Once she had reached him, he barked, "Well I know how to teach respect..."
He grabbed her and pulled her over his knee, in front of the whole class. Reaching down, he pulled her skirt above her waist, exposing her panties to the class,. As he yanked her panties down, she cried, "Please! Don't!"
He spanked her hard on the ass. It stung tremendously, although the humiliation of being spanked in front of her whole case stung even more. He spanked her butt again. Her large boobs jiggled madly, and her buns had turned pink. By the third smack, both her face and ass were scarlet. She stopped protesting soon, stoically taking it, silently crying. After about ten spanks, he let her return to her seat. All her classmates were giggling as she hunched in her chair and tried to avoid their gazes.
Horrible as this experience was, whenever May thought about it, she grew horny. She eventually ended up masturbating to this memory, at the way her body felt. It was then that she realized she had to do it again.
A month later, the opportunity presented itself. She was at the school doctor's office, which had one room off of a waiting area. The male doctor had been there for a few years, after dropping out of med school. She had gone in for a headache, and, when he began to close the door of the exam room, said, "It's pretty hot in here. Could we leave that open? It provides a nice cross breeze with the window."
He obligingly left it open. They got through the obligatory smalltalk, and he began questioning her about her headache. Eventually, she just took an ibuprofen and that was that. However, May asked, "I was wondering if you could show me how to do a breast exam... I read that periodic checks are important to finding breast cancer early."
The doctor, blushing slightly, replied, "You simply rub your breasts for a while... Try to feel for any unusual bumps or things inside..."
