I need to clean my new flip flops and I have my slave to do exactly that function for me. The problem is that I will be using your tongue for a long time, how can I solve this? I already know! With my spit! I can use your tongue for as long as I think it takes to clean the soles my new flip flops and then my feet's soles, as I can spit in your mouth whenever I think your tongue is getting dry. Man actually has several functions and an enslaved man even more function available.
