My Wife's Exam

I'm not sure how to classify this story. But recently my wife had to see a doctor about an irregular pap test. She is fine.

One of the exams she had was, by her description, a 35 something doctor and a younger student (also a woman). She was up on the table, and spread wide open by the speculum. The doctor (a woman) and the student were looking up her vagina. They of course started the insertion by holding open her lips (mostly shaved). They decide that there is nothing wrong with my wife and then the student says that she is just going to insert a tampon for her.

After the exam is over, my wife goes home and says the thought of being so exposed to two strangers (and women) made her so horny she had to masturbate for an hour or two. My wife is not bi or gay.

I'm not sure what makes me so hot about it, is it the fact she was being held open for all to view by these women, or the thought of one woman inserting a tampon into her or was it my wife masturbating at home afterwards.
