I just recently found this forum and I like it very much. Now I would like to contribute.
The story to the pictures is that my father is a dentist and he has got a lot of female medical secretaries. Some of them are quite cute. Sometimes by night or when its closed I take the keys, go to the room they get dressed in and cum in their working-shoes (Birkenstocks and similars), which they leave there. The next times I enjoy watching them while they wear them...
I took some cum from the previous shoe with my finger and rubbed it into the next one...
The next ones were taken a few weeks later and in the first shoe you can see my dried cum which I rubbed in there with my finger. Wonder if they ever noticed something...
Hope you like them. Fell free to comment.
