I arrive back from the gym and My feet are very sweaty. I prefer to have My slave lick the sweat off rather than have a shower straight away as it is what his mouth is for. I not only gag him by putting My foot into his mouth fully without any gaps to clean every part of My feet but also want him to lick My sweaty feet very well without leaving any space on My feet – top of the feet, soles, in between the toes well.
