I think I developed an unnatural and weird habit: I like to sneak in my brother's bedroom and to suck his cock while he's dreaming and then I would sneak back into my room without him knowing or noticing anything unusual. I did this several times and he didn't wake up, so I started to do it more often! I have this fantasy of brother-sister love, I think it's because I read about this in a book by Vladimir Nabokov (it's called "Ada or Ardor") and I became more and more interested about taboo subjects until I finally decided to try it! I am in love with my brother, but I have no idea if he feels the same about me. He loves me, obviously, but as a sister, ignoring my sexy body and voluptuous tits. I knew he would never get involved with his own sister, even for an innocent blow-job, so I chose to act during the night. He usually goes to bed naked in the summer and almost always has a boner, probably his own fantasies translated into wet dreams. He doesn't have a girlfriend so I feel pity for him, he has such a big cock and he has to please himself, because there's no one to do it for him. I also knew that if he ever wakes up, it would be a little weird, but he would already enjoy it so much that he would let me finish my job. This night, it happened. He woke up while I was putting his cock inside my mouth. He suspected that I'm doing strange things so he put a camera on a tripod to film what happens during the night. I saw the camera, but didn't think much of it, I was horny and I wanted to feel his cock back into my mouth. I was rushing, so I think that's what woke him up. He was outraged, astonished and a little nervous. I manipulated him without letting him see I'm manipulating him, in fact: I told him frankly and "sincerely" that I will stop any moment if he doesn't like it. Of course, it went exactly as planned: he didn't ask me to stop. I believe that the DeepThroat part weighted heavily in my favor: such a big cock doesn't get DeepThroated too often! I used all my skills to make him feel heavenly, I wanted him to notice I'm not just his sister, an asexual identity, but a horny submissive woman that will do everything to please him. I've given head before, but this time it was very special to me, because it's about my own brother. He continued filming all of it, I asked him not to post it online but keep it for himself, as masturbation material. I think he'll have material enough for a whole year. He filmed me POV a lot, but also from the side/profile and I noticed he did some close ups during the most intense moments. Hearing my brother moaning and pushing his cock deeper into my mouth made me feel so happy! In the end I played with his orgasm like a cat with a mouse, edging him until he was very near cumming, then stop for a few seconds and doing it again and again. I edged him so hard that I was able to make him cum only by tickling his tip with my tongue while looking him in the eye! His cum sploshed everywhere like the 4'th of July fireworks on the sky
