I fantasize about my brother-in-law
My sister and brother -in-law have been together for 9 years. About 4 years after they had met, we all went on vacation. Now before I continue, I just want to say that I'm a guy and if you're homophobic you should probably stop reading. Well, on that vacation we were house-sitting for family of ours and they had a pool. One night it was just him and me in the pool and even though the water was pretty cold, I was so turned on by him, and I didn't want to get out the pool in that state. The next day we were all outside relaxing by the pool. Eventually my sister, brother-in-law and I decided to go inside and dry up because we were in the mood for some movies. My brother-in-law went into the room he was sleeping in, to change, and my sister dared me to knock and the door while he was changing and then I should ask if I could change in there. He didn't laugh about it. He didn't even pause to think how to reply. He just said, "Yes, you can." And judging by the tone of his voice, he wasn't freaked out about it. I so wish I did go in there but I didn't because I was just dared to ask about it and I could just change in the room I was staying in.
I don't fantasize about him daily and it's not something that takes over my life but some days I can't help it. My sister and brother-in-law stay with me and when it's just me and my brother-in-law at home, I can't help but picture him naked when he takes a shower. Sometimes I feel soooo tempted to peek through the keyhole to see what he's packing but I wouldn't actually do it because I wouldn't want that done to me and I respect everyone's privacy. And then sometimes I wish I had a reason to go in the bathroom to "get something" while he is taking a shower. But I don't have the courage to do that and I wouldn't feel good about lying. He swims for exercise but we don't have a pool at home. Anyway, I have seen him in his black speedo before but I didn't get a good look because I'm paranoid about being caught looking.
I remember a day where he wanted to show us a bruise that he had from falling and he just wanted to pull his pants down a little on the side so that he didn't flash anything. But he tugged a little too hard and I got a quick glimpse of his bush. It was so close and it was so hot! He quickly pulled his pants back up and I could see him blushing a little.
I don't give a damn about how big or small he is. I just want to see it because it will be hot either way. Even though penises are very similar, at the same time no two penises look exactly alike. The mystery is such a huge turn on for me and even if I see it, I'm sure I would want to see it again and again.
The impression I get from him is that if I were to see him naked, he wouldn't mind. But I would never invade his privacy and I'm obviously not about to ask him if I can see his ****. I would not only feel bad about invading his privacy, I would also not want to do that to my sister. They are both special to me and I don't want to jeopardize that.
What can I do about this? Ideally, I would like to stop thinking about him in a lustful way completely. But I can't help thinking of what he might look like naked.
