She shoves her stocking covered feet in his face making him smell and lick the scent of her sweaty nylons worn all day. When he fails to lick them fast enough she grabs his leash and foot fucks his mouth into submission.
Not satisfied yet, Mistress Hannah shoves her feet deep down his throat gagging him until his lesson is learned that worshipping her feet is a privilege not a right.
She enjoys his warm tongue sucking on her clit making her pussy moist and excited. The slave gets visibly excited from pleasing his Mistress, his cock swells with making his erect.
She edges just the head of his cock bringing him to the brink of insanity but never actually allowing him to cum. Slave's are so much more submissive and obedient when kept horny and on edge for their Mistress.
