I’m a guy who believes in being bold and all, but I also believe that there are one or two lines you simply don’t entertain the thought of crossing. Kissing your sister is one of them. Apparently, this rule doesn’t apply to Playboy twins, Kristina and Karissa Shannon. The 20-year old biological sisters were seen swapping spit at the Playboy mansion this weekend. If they’re doing this in front of cameras, just imagine what they’re doing in the privacy of Hef’s bedroom. I guess what I’m trying to say is that these skanky hoes need some serious therapy.
