Tied up and tickled on her soft soles

Ivet is tied up and weak and you with the help of Charlie are tickling her soles. Ivet is not ticklish at first, she's able to stand it but over time she grows weaker and weaker until she can't take it anymore. Her soles are just inviting you to tickle them. Don't be shy to tickle her as much as you can. After all she agreed to be tied up on the bed and tickled. But her feet look also so sexy! Her soles are very soft and just perfect and you're allowed even to worship her feet if you want. Tickle and worship. That's the deal. Are you in?
