Greg Foster was one of my favorite models. I've always been a sucker for guys in their twenties with prematurely gray hair. But there was also something so innocently sexy about Greg, looking so submissive and vulnerabile when I answered his knock on the door, that I fell in love with him at once as he stood in the doorway and only regretted he was someone else's slave. Fortunately for me, his Master was a generous man, and I had many opportunities to get together with Greg and tie him up and get to know him better. We became good friends.
I've shown one or two photos of Greg in a sleepsack before. Here's the whole series from that photo set.
