Incest Jokes

My wife just said, "It's your turn next, what do you want for Father's Day?"

One morning my hot 15 year-old sister came into my room crying. Dad had finally told her that her real parents were unknown - she was adopted.

I was a good big brother. I put a comforting arm around her, and told her that it doesn't matter, that we'll always love her, and that I thought she was the most wonderful sister in the world. Then, I dunno how it happened, but we kissed, and soon things got really passionate - clothes came off, and... we had the most amazing sex.

Sadly, it didn't last. After I came, I found out the condom had split. She started crying again, and I got the shakes. We went downstairs, hand in hand, to break the news to dad that his adopted daughter was probably pregnant.

I have never been less amused by the words "April Fools".

Little Johnny smiles, "It's not so fucking funny when it's YOUR mum, is it?"
