In one picture, a boy who looked a lot like me was on his knees, and a burly man who was bulkier than dad was behind him, his cock angled toward the boy’s hole. I was jerking it, as I scrolled through images, read some of the stories. I had a search window open and was typing in “dad son fucking”. The next thing I knew, I was clicking at my computer instead. I tugged on my limp dick instead, thinking about what I’d done with my dad and how badly I wanted to get that back. I went to my desk, still with no pants on. I had more calculus homework, enough to last all evening. I lay there with my pants off still, wondering what to do. My dick was already soft as the door slammed shut.
