My intro to cock

Why I am bisexual? I have an idea. All I know is I love everything a woman can do. Fucking pussy and ass, great blowjobs, I love it all. I love the look of a woman’s body. They can be fat or skinny, it doesn’t matter. I think they are so beautiful.
But I have this other stirring in me. I am not really turned on by guys, but I love dick. When I see pornos, I love the dick going in and out of mouths pussies and asses. It could be fucking a guy or girl. It is just hot to me. I fuck my wife almost daily, but I dream of cock pounding my ass and shooting in mouth. I must be a real cock slut because I often draem of both my ass and mouth being filled at the same time.
But how did I end up that way. I think it started when I was 10. My brother was 7 years older than me and I had caught him fucking gorls a couple of times. It was hot to see him humping these teen girls with his long teen dick.
One night I saw him sneak the next door girl in his room. I could hear them fucking in his room next door. When he sneaked her back to her house he told me to come in his room.
We started talking about what he was doing. I only had some vague ideas. He said it felt great and started talking about masterbation. He asked me if I wanted to see. I was excited and told him yes.
He pulled out his dick. It was a curious sight for a 10 year old. It was soft, but had good length and all that hair around his cock. He started stroking his cock up and down and explaining to me the finer points of jerking off. He cock grew in size and became really hard.
