I felt guilty for days after that. I could hardly look Sam or my brother in the eyes. She was his girlfriend, for Christs sake! I shouldnt think about...shit like that. And yet, a few days later when I accidentally opened Ryans door after hed told me to wait, my cock hardened instantly when I heard Sam squeal and rush to cover herself up.
