No- it is NOT referring to incest for heaven's sake! LOL
It's an expression used to describe when there's a lack of joy, pleasure or passion in doing something. (True enough if you were 'kissin' your sister"--blechhh!) If an experience was dull and unexciting, someone might say "yea, it was l like kissing your sister". And the expression can be used to describe almost anything that was dull, lifeless, boring that someone would not want to repeat doing.
