Has anyone ever had sex fantasies about their sister?

Is it normal to have fantasies about your own sister? I have seen my sister naked a few times and have secretly watched her masturbate I have only watched her but it is fun to see her, I think she knew I was watching and really put on a show, is it ok to watch her if it doesn't go further? Any girls have fantasies about their brothers?

  • You know. Long story short I figured out a way to eavesdrop on my neighbors phone calls when I was in high school. They had a son about my age and his conversations with friends were classic. One night he had a conversation about how hot he thought his sister was and how he'd totally get with her if they weren't related. He always struck me as being a little weird and this further supported that idea. He was a 15 year old boy though. I find your behavior kind of sickening and a little disturbing.

    However... I did some googling and found the following on Wikipedia under the topic of incest, "Consensual incest between similar-age brothers and sisters is not uncommon, according to a study by Floyd Martinson, who found that 10-15% of college students had childhood sexual experiences with a brother or sister.[10] However, only 5-10% of those included intercourse, and therefore most probably represent a form of child sexuality based on experimentation, rather than incestuous desires."

    At your age it clearly isn't experimentation or curiosity...

  • It sounds like the sort of stuff you do when you are teenagers. I caught my brother masturbating a couple of times when we were younger. He saw me naked a few times in my teens but I thought nothing of it cause he is my brother, it was no big deal. He might have fantasized about me, but maybe not. If he did I think it would be cause of all the hormones happening at the time and I was a girl. If you live in the same house some times you catch people in compromising positions.

    The worrying thing is your age is between 36 and 45, so to be watching and fantasizing about your sister now is probably not just out-of-control hormones. Maybe you should let her know you saw her and if she leaves the door open or closed in the future is between you guys.

    • Couldn't have answered it better myself (and I'm not going to bother). Now all I need to do is figure out how I got here after a 'chain of question answering' that started with "what did you get for Christmas.

    • my sister is hot i would love for her to blow me

    • @jacskittles Same here!!

  • FIRST THINGS FIRST That is wrong and you should stop watching your sister materbate because that is sick and maybe consider going to therapy I have five brothers and I have NEVER EVER IN MY LIFE have had fantasies about my brothers ....they're family and you shouldn't even be thinking about her in that way it's NASTY

    • When I was a teenager experiencing the flood of hormones during adolescence for the first time, I also had these same fantasies about my sister. Never acted on it. Regardless, these fantasies were there nonetheless, despite my will to attempt to drive them from my mind. I recall a TV show with Dr. Drew that covered this particular topic and Dr. Drew stated it's actually normal for siblings to fantasize about one another at some point in their lives. And speaking from my own firsthand experience, the people who have these sibling fantasies don't need more people condemning them anymore than they are already internally beating themselves up over it. I'm sure that the writer of the original post is experiencing the same emotions all incest fantasy hosts have– guilt, shame, perverse, disgust, etc. They don't want to have these bizarre fantasies about their siblings, thus they feel worthless and disgusting as a person as a result of having these disturbing fantasies.

  • Hmmmmmm,........

    I am sure that siblings are not unaware of the attractiveness of each other, and I am sure that there is experimenting to some degree that is typically limited to the younger years though.

    While there may be a perfectly healthy psychological explanation for this, truly the first reaction is, ewwww. While I am not saying that anything is wrong with you, I might suggest a healthy discussion with a qualified psychologist,.. this might be nothing, or it might be a symptom of some other issue (child trauma, relationship issues, etc).

    Something about this makes me feel like this is a symptom of something else, and I truly think you could benefit from talking to someone.

    Best of luck.

  • guys (and women sometimes) will have dreams about the closest opposite sex person they have to them, yes that means I had a dream about my mother. does this mean anything? no, just means I have urges, that I'm controlling consciously, but subconsciously, the desire for sex, leads me to want the nearest female, and since it was at one point my mother than yeah

    i think its normal for you to have this, as long as nothing else is going on... try getting some female friends, or better...a girlfriend

    and sorry if this was a little graphic for any readers here

    • CREEP. It’s your type that made me wish we could easily get peoples identities off the internet.

  • I have to say that I find this story disturbing... this is totally NOT normal... if you are looking for some fun or sexual distraction go and watch porn but don't go and check out your sister... that's totally sick!!!

    And your other question, I have never had any sexual fantasies about my brothers or cousins....

  • I agree with April on everything yes there are studies and people have done that but um I'm sorry but I find that disturbing as hell...damn go watch porn or something

  • While you can't help your attraction to your sister ,what you are doing is morally wrong. You shouldn't be invading her privacy and watching her do things like that. What do you think your sister would do if she found out about this? Why don't you focus your energy towards women other than you sister who have similar qualities that you like in her? Really, you can't continue this type of behavior, it is incest and just wrong on so many levels.

    • Homosexuality is morally wrong too yet that doesn't stop 80% of women from having and engaging in those fantasies

  • I don't think that's right...one day you might end up taking your fantasies too far and might rape her on mistake.so stop what your doing cause you could hurt yourself and others.

    • Yea, because fantasy = Rape. Lol. Lemme guess, you are a firm believer and reader of the bible-myth and you're a republican?

    • @PlasticPromises lol that is great

  • I don't even know what to say to this! You and your sister must have a weird relationship but if you are both ok with it that go right ahead and get your jollies while you can but I'm going to have to say that it is sick!

  • U better stop watching her,even if it's fun.cuz it is ok.there are these stories about sisters and brothers in royal family getting married and having sexual fantasies which I have read but they blong to 700 years ago!it's now 2008,and in 2008 i's not ok.stop watching,try sth els instead.like watching Ur Gf or porn.NOT Ur sister.

  • I'm up for anything but incest, it's so sick. You and your sister obviously have something screwed up going on, but if you're both fine with it, go perve on your sister.

    • is it really? It's funny you would say that. do you know what horrible things exist out there? of course you do, 'your up for anything' right? you've done it all then? you've had sex with cuts and scrapes plants and death. you've stabbed and been stabbed been bound by tape? strangled and mangled, crippled and secreted? have you hallucinated from a lack of air, caused by being crushed by a beast? is there a body in your bed giddy thoughts of blood in your head? you need to watch what you say lady. what you think is sad or bad, can easily be trumped. people being raised togeher and eventually having relations isn't a bad thing, compared or not. it may seem weird to you, and it seems weird to me, but just because something seems strange doesn't mean its evil or wrong. consent is key. if it's consensual, truly, then a whole plethora of weirdness should become ok. It won't be accepted as such, but it TRULY IS ok. now get your head out of your ass, your making a fool of yourself.

  • Three letter for you WTF! Do you know how sick that is dude. Like honestly. That is sooo unbelievably wrong. I can't believe you even have the balls to post that question on here. Lol. Good thing you asked anonymously. Lol. Geez. SEEK HELP!

  • no. I really feel uncomfortable answering this because my brother molested me when I was younger. I couldn't do anything about it and iwas scared to tell my mom or dad because they would think that I liked what he was doing to me. I hated him and I used to beat him up and cry every night over it.

    • Thats f***ed up. I'm sorry.

    • i feel sry wht happened with u

  • When I was about 13 I did! ... But, I didn't know it was my sister. It was a sleep-over, it was semi-dark in the room, people were asleep, and I saw a figure laying on the bed that looked good. I just assumed that it was my sister's friend, but it turned out to be my sister, and I felt stupid.

    • Creep

  • NOT normal.

    • I agree; this is not normal behavior. Very perverted!

    • @lovebird01 So is anal sex. And sex for pleasure. Mammals were made to mate and procreate and NOT be monogamous for a reason. To make babies. Period. You realize you can thank pretty much ALL of mankind on incest? How do you think people became a civilization after Adam-myth and Eve-myth were created by the God-Myth? Do you think that they just appeared out of the ground from cabbages? Maybe storks brought it all in. LOL. Nope, Adam and Eve had babies with their children who had babies with their children and so forth. The large majority of former and current aristocracy of most countries are heavily polluted with incest.

  • Dude, you're such a creep. That's definitely not normal. e. e

  • There's nothing wrong with fantasizing, though I haven't personally had this one. If she's masturbating in private and hasn't expressed a desire to be watched, you should respect her privacy.

    • Yes it is, y’all are gross. And y’all know it.

  • that's definitely creepy af

  • I have current sexual fantasies about my sister. I'm 28 and she's 26. I think she's very attractive and I have thought about telling her. I decided to keep it to myself because it's a fun fantasy.

    • She probably knows, and that’s the reason she doesn’t like to be around you now. Creep.

  • No its not normal. Its sick as fuck, and being the age you state you are.

  • Weirdo porn is role play not for u to wanna get ur sister

  • That's hot

  • Dude your f***ed

  • Yes. I've had fantasies about f***ing my sister. I probably wouldn't do it in real life, but to be perfectly honest - she's got a great body and it's such a tease. I'm secretly sexually attracted to her.
