Ever since we were 15, my step brother and I have been having sex with each other. Our parents started dating each other just after my brother and I had sex for the first time.

At the time we were just friends having sex. Then our parents started dating and we tried to play cool and not have sex anymore but we were teenagers and couldn't help ourselves.

Then our parents got married amd that made things more complicated even though I gave my step brother a bj at their wedding. Then later at the reception we found a quiet closet and lifted my dress up as I bent over a janitors sink.

Ever since then we have become all but lovers. We spend a lot of time together, we cuddle, we make out, have oral sex, have regular sex almost daily. Half the time I sleep with him in his bed and sneak back through our connected bathroom to my room before our parents wake up in the morning. Sometimes we shower together also. The only thing keeping us from being boyfriend and girlfriend is our parents marriage.

It is technically not i****t so we don't care about any gross factor and we have been having sex with each other since before our parents knew each other.

Recently my brother and I started looking at possible apartments for us. That way we could be together the way we want to without anyone catching us.
