Naughty Doctor

A man just went to an eye doctor and everything looks normal. She starts with checking his eye sight and concludes the problem isn't bad eyesight. Turns out he doesn't know the letters. She quickly switches to a dominatrix and begins to punish him. She gets angered when he pronounces letter B instead of A. To help him out, she comes up with a sexy trick that made him remember letter A. If he gets it right, she promises to ride him as he takes the test. Sounds like a nice reward, right? He most definitely gets it correctly and makes her cream all at once.
