wow her great big tits love to suck them I want a granny like her

I'm 19 and a male who is a college freshman. Several weeks ago I got the shock of my life, I arrived home at 10 in the morning. My grandmother lives with us since her husband died about 3 years ago. I heard strange noises coming fro her bedroom so I went in to see if she was OK. I saw her on her hands and knees completely naked. A black guy was fucking her and those were the noises I heard. I closed the door and went to the living room. About 30 minutes later the guy left and Nana joined me. I promised I would not tell anyone what I saw. I asked why she was on hands and knees and she said that was the best position to be in when a guy is fucking your butt. I kept my promise not to tell, but I must tell someone before I go crazy.
