I have him bound on the bed with his mouth firmly taped shut and blindfolded. He then spends the next 13 minutes with his face buried deep in my moist gym socks while I watch some Netflix. It's so relaxing and satisfying I almost fall resting several times! After a while the thought of my bare soles becomes too much for him and he's able to move his hands enough to peel off my socks and wedge his nose firmly between my toes.
