My true lover
I'm a guy, 34, that has always lived jumping from one relationship to the next for a reason: I cheat on them all from the beginning. The explanation for it is that my older sister (37) and I have been in love since we were teens, and we're addicted to each other. No other person triggers such lust in us than we do in each other.
I couldn't explain why it happened, but we were very close since we were little, and our mother wasn't around much because of work, she raised us alone. So when puberty kicked in, giving in to our impulses to kiss and experiment came naturally. Eventually it was sex: I lost my virginity to her. We know it's wrong but we could never stop ourselves. On the contrary, the taboo around it made it more compelling. it was only until our 20s that we decided to date other people to keep appearances, but in reality we're only truly in love with each other.
Perhaps a lot of people suspect us, going unmarried for so long and me going to my sister's place "for lunch" so often (I'm the only man that consistenly walks in and out of that appartment and she's incredibly loud when she cums, and I'm guessing the neighbors are not that stupid). the only person that knows about us is one of our best friends, who openly accepts us and is even involved in our sex life every now and then (we sometimes have threesomes). It's a frustratingly secretive lifestyle, I can't tell the world who's the woman I love and find so sexy. But I wouldn't give it up for anything.
Why tell: it is working without a problem
