Teacher Confession #4

Kevin, 17, is the mentally challenged black boy that is in a special needs program new at the school this year. Teachers are asked to help with the program by selecting one of the few that there are  and to have them do various assignments around the room like cleaning up and doing light inventory. It didn't take long to figure out the black boy was a keeper. Communication was poor and he was bused in from an urban housing program from the city with other special need students and the staff that looked after him were poorly trained, preoccupied, and uninterested in the students and just cashing in a paycheck. Sad, I know, and even sadder that I take advantage of the situation but the dark boy has an incredible fat chocolate dick. One that I can nurse on for hours considering the shuttle that picks him up is often very late.
I've recently started lubing him up, laying him on the floor and sitting down on his cock, riding it hard. He seems to enjoy it and laughs a lot until he starts cumming, then his eyes get real big and he gets excited but I always manage to keep him in place until I cum and he fills every drop of thick cream up my gut.
