Cum covered picture in the woods

Went running in the woods yesterday. Discovered a topless picture of Rosie Jones ripped out of a magazine on the ground at the edge of the path. It had what appeared to be cum on it where someone had used it to wank over! Got me instantly hard so there was only one thing I could do! I wanked over it too and added my cum to the picture!!!
Wish I had had my camera to record the event. Also wish I had run by when the original wanker was there, would have offered to join in and help out.
