I met this girl and somehow happened that we ended up having sex.
Next day when I left her apartment, a thought crossed my mind. ... She is my sister... No, not really. I know for sure I don't have one, just joking.

Buuut she was older than me, she was from the same city and had the same name as one of my female 1st cousins. I tried to remember how she looked back in 1998 when I last met her. But everything's blurry: brown hair, brown eyes, fair soft skin, older than me (but how older?), nothing else.

Even if she was my cousin, it crossed my mind when it was already too late, it was just a one night stand, we used protection. I wouldn't even feel disgusted, it just happened.

Now if i'd have a hunch she might be a long lost sister, BEFORE actually doing it, I would actually say it... talk and determine if we are indeed siblings. If we are, I'd laugh it off. I believe you should be pretty desperate and frustrated (sexually) to still wanna do it if you know she is your sister.
