Mistress Linda, it's always wonderful to hear from you. In my humble opinion your sissy shouldn't have a say in what it will or will not do. If you want your friends to receive pleasure from your sissy then it should be done. Sissies serve, they don't get to control who and how they serve. Perhaps your sissy needs to reconsider its position in your household. Your sissy should want to do this because it makes you proud and happy.
