I started to turn away, then stopped, turned, and said, “Hey, Toby... watcha watching?”Toby turned his head toward me and dropped his hand from hi...s cock. He was sitting in my office chair with his pajama bottoms partway down his butt. His cock, poking up from his lap, remained hard. While he tried and failed to stammer an answer, I walked over and stood behind him. On the screen was my Lushstories page, a picture from the photo album... with my own naked image staring right back at me. And in. " It doesn't matter.
