Found vids of my straight brother fucking women in my guest room

My brother was staying with me for a couple months, and one day when he was out, I heard his TV on. I went into his room and a video was playing. Its was him and some woman. There were 14 vids, and I watched all of them and jerked off to my brother. Im going to leave a vid of me humming on his bed watching him use his big uncut cock, like a replica of mine.
