"I Love My Sister, We've Had Sex & Want To Marry Her

Dear readers,

I have a sister who i so much love.We stay together, we play together, we sleep together.

One day we kissed each other coincidentally and since then we have been having sex, but before then i was a virgin and she too was but we lost our virginity to each other.

And now she said she can't stop it and i wish like getting married to her and she wishes so too.
Yesterday she called me from school and told me that she want us to do it again that i should come over and i'm confused on what to do because if i impregnate her, it is an abomination.

If my parents find out i'm FINISHED, please what do i do to save myself, can i get married?.

Naawaaooohhh!!!!!!
