Cat has got a real foot fetish and loves having her toes sucked on and played with. She always keeps her feet manacured and soft. Taking every oppurtunity to show her feet off in sandles or flip flops she loves having her toes played with. The the best form of foreplay for her nothing else even comes close to get her turned on. Starting with a gental foot rub that gets harder and rougher as it goes on. Eventaully having her partner lick and suck on each individual toe by the time she has all ten toes licked she is more then ready to do her own share of licking. As long as her man has clean feet she also loves playing with his and putting his big toe in her mouth pretending that she is sucking on his dick. Teasing him as many girls do by sucking on a mans finger she gets the same effect by sucking on his toes. Its even said that she has has orgasims simply by having a man take his sweet time sucking and pulling on each of her toes.
