2 years of sweating on 6+ hour shifts.. Sweaty embodied within these soles to the point they are discolored. Just the way your freak foot lover ass likes it. Come sniff, kiss, and suck the sole clean like Goddess wants. It's an honor for you to be able to see the work put into these shoes making other loser subs happy. Take pride in your kink and deep further into this subspace with me.
