Anne Curtis and Equally Hot Sister - Scandal or Not?

This was sent to us by an avid subscriber saying he got this from his group somewhere. At first I thought it was some lesb0 act. But when I read the description, that was the only time I realized that one of the girl was Anne Curtis. And the other one is her sister.

Was this made out of fun or what? Hope it was, coz its really disturbing if now.
