He is 18, you are 14. If you fuck he can go to prison. Also in many places incest is a crime and he can go to prison for that as well. That said, there are only two ways he can go to prison, either someobody catches you two together or you tell somebody. You would be surprised how likely it is that your most trusted best friend will rat out your brother if you tell them. So in other words don't even think about doing this unless you are absolutely certain you willl never tell anyone and can do this descretely. That said, just be as sexy as you can around him, tell him you want him and make yourself available. Sex at your age is awkward as it is, and incest is especially so but if you truly want it go for it. Just don't let yourself get pregnant until you are the legal age in your area.

Incest is by definition, awkward. Even if it wasn't awkward for you and felt entirely natural as some incest practitioners insist, it would still be awkward elsewhere, say revealed to other family members or in greater society. Personally, I don't think it is at all unusual to feel attraction or a sexual response to certain family members, even if they piss you off otherwise most of the time. I don't think it is "wrong." It is what it is. As a growing teenager, I couldn't get within one foot of my unbelievably sexy mother without getting an automatic hard-on. It was embarrassing. And, yes, I argued with her all the time. She drove me nuts. I should warn you that if you go down this path, many have reported a kind of intense sexual bonding that can follow you through life. The sex can be very hot. Then again, others have a little fling and then it ends mutually at a certain point and life goes on. So, who knows? Now, your brother is not entirely innocent here letting you see him nude and saying sexual things to you as you come into your own sexuality. Strictly speaking, this is a form of sexual abuse in itself. That you are responsive in any way does not change that fact as your response can be seen as simply a natural part of your own blossoming sexuality, which he may want to exploit for his own pleasure or sense of power. I think you are being manipulated if I know horny teenagers (having been one myself), but then maybe you don't care. You should at least be aware of the possibility. There's also a power imbalance as he is significantly older and more experienced. He seems to be a bit of a jerk (but then so many guy-guys are). Having sex with him would no doubt change your relationship. Hard to say whether it would be for the better. Best of luck.

Not a good idea to get sexually involved with your brother, life time regret if you do this. You can masturbate and please yourself but leave the brother out.

You must not say sexual talk with your brother in such a manner.
