Unless incest just happens to be your thing.

And remember folks if theres anything we've learnt from tv, film and media, its that one in a million chances happen 9 times out of 10.

One of the greatest pr0ns I ever saw was twin sisters. I know, I'm gonna burn in the lake of fire yadda yadda yadda...

This is actually not all that uncommon, the problem is the two siblings meeting in the first place, but if that actually does happen, its well documented that they will usually feel there is a strong bond between them (its probably related to Pheromones), but since they dont know they are siblings, that bond is often misinterpreted as "falling in love", and there you have it..

Infact i know a girl it allmost happened to, they went on several dates before they found out they had the same dad, luckily they never went all the way..

Pheromones were very important during ww2 to spot disguised intruders. Read this to learn more about that:
