The old man seduces his young student

There is a young woman, a very bright one in my class. It is so good that I decided to hire her as my assistant. It helps me to prepare lessons, and assess the examinations. This made me spend a lot of time with her, and as a result I started to develop sexual desires for her. It was always more difficult for me to control my impulses, until one afternoon I made more and I kissed her. Fortunately, I refused. So, I continued to put my hand in her vagina. It is de-energized. I have removed the clothes and I did oral sex, and her wet vagina was a pleasure in my mouth. Gave me a blowjob and then I fucked her on the couch.
