In case you don't know who Skylar is .. she is Cathy's step sister. Apart from that she is also the closest example I know to a true nymphomaniac. I saw that because Skylar is obsessed with sex and orgasms. At times (lots of times) it's like she just can't get enough. Check out this video of Skylar getting off with a vibrator when we had a threesome with her last year. She used that vibrator for over an hour before I stopped her and fucked her some more.
