My wifes nephew was staying with us for awhile. I didn't care for him much, he didn't work and just spent all day on the computer.
I came home one day and found the lawn not mowed like he was supposed to do. I went to his room to tell him and found the door slightly ajar. I looked in and found him on the bed stroking himself and looking at a nude picture of my wife that he apparantly took from our room. I was intriqued.
I couldn't take my eyes off of him as he stroked his suprisingly large shaft to a picture of his aunt. His cock was surrounded by a huge bush of brownish blonde hair. I found myself rubbing myself through my pants. After a while he came hard. I went to my room and jerked off to a huge climax and think about it often.
