JO with Uncle

When I was 19, i went to spend the summer with my uncle at his country house. Being a professor of medicine, he had many books that dealt with anatomy, diseases, etc. After sepnding a couple of days there, i felt some sharp pains in my abdomen, and afterwards went to my uncle for some medical advice. As i entered his library, i saw him reading one of his medical books, but in reality, it was a hustler inside. He was sitting there with his pants pulled down, a black tight jockstrp on, a finger in his ass and another hand jacking his 8"uncut cock. When he saw me standing by, it was no suprise since I was used to seeing (and hearing) his female students when they came into his apartment in the city. Boy would they have fun. Sometimes he would even set me up with some of his hot students. Anyhow, there was my 6'2", brown hair brown eyed, unclye jacking his cock. However, this time I asked him if it was OK if i could join. i haden't jacked or fucked for a couple of days and needed someting hot to turn me on. Luckily i had him and his collection of porn to help me out. As i sat with my legs spread on his desk and my rock hard cock between my legs, i felt a sudden buildup in my groin. In a matter of seconds i cummed allover his desk, books, and him. That's what was cauing my pains! All of a sudden i felt him erup all over me as we sat there laughing. He said "next time lets have a double date!"
