A special kind of mariage
I'm a 35 year old woman that's been in a happy marriage for 10 years. my husband is 42. and the reason our marriage is happy is because of a mutual, honest understanding and respect and inconditional love, no matter what the circumstances. and for me, there were very special circumstances, since my older brother and I have been romantically involved since we were very young.
we always loved each other in a way beyond normal siblings and while we knew society would never accept us, we always accepted our feelings towards each other. we were never conflicted about them and it came naturally to us, so he has been my "boyfriend" since I was 13. I was 15 and he was 17 when he took my virginity. I didn't have sex with any other man for almost a decade, even if we were used to dating other people briefly to "keep appearances". by it's very nature, our relationship had to be open to other people, but we didn't have sex or fall in love with anyone except each other for many, many years.
we lost our parents shortly after he turned 18, so he was allowed to become my guardian until i became an adult. we essentially lived like a married couple from then on. no one knew, we had few friends, no other family, and inherited enough means to get us both through at least high school.
until i met the man that would become my husband. it was supposed to be another decoy partner, but I fell for him and he fell for me. it's a very long story of how I came to tell him about my love life, but surprisingly he was very accepting ("love is love", he says, and I agree). my brother had a much harder time accepting it, but he eventually came to terms with the fact that i could love them both. the three of us have had a polyamorous relationship since then. two years later, i was married... and my brother came along to live with us.
the three of us share a place. to keep appearances in front of guests, my brother has his own room, but the truth of things is i sometimes sleep with my husband, sometimes with my brother, or sometimes both at the same time. it's very fulfilling sexually, and also spiritually to be able to have an open, accepting and loving relationship with both. and have kids, on top of that.
our firstborn was a perfectly healthy girl... my brother's child. right now i'm pregnant with a boy, my husband's son. for obvious reasons they're both registered as my husband's children, but the three of us will raise both kids together. we haven't decided if we'll ever reveal their true parentage to them (we're leaning towards not doing it), but only time will tell.
