My little sister Nyx had has her friend CJ over this weekend. CJ is an instigator and a trouble maker. They called me in and they're in their panties, talking to me about how my little sister is shy around boys. CJ says "there's no need to be shy, watch..." then takes out her tits. My sister follows suit and it got really fucking weird. I've never seen my sister naked like that before. I feel bad saying it, but I really liked it. CJ is smoking hot too. Then they start flashing me their assholes and pussies...
