She dropped to her knees the second he walked through the door. His work boots were caked with dust and his feet had been trapped in those thick black socks all day. The smell hit her first, that heavy, musky scent of sweat and man that made her cunt clench. She pressed her face straight against the top of his left boot.
"Take them off," she said, voice already hoarse.

"I want your socks."
He smirked, kicked the boots aside, and shoved his socked feet toward her. The fabric was damp, warm, and yellowed at the toes from hours of wear. She buried her nose right in the arch of his right foot and inhaled hard. The sharp, ripe smell flooded her lungs. Her tongue came out without thinking, dragging a long, wet stripe up the sole from heel to ball.
"Fuck, that's it," he growled. "Sniff those nasty socks like the filthy girl you are."
She moaned into the fabric and rubbed her cheek against it, smearing her own spit. Her hands went straight to his belt. She yanked his jeans down, freed his cock, and wrapped her fingers around the thick shaft while she kept licking. The sock tasted salty and bitter. She sucked the toe fabric into her mouth, chewing gently, then moved to the other foot. Both socks were soaked now from her mouth and his sweat.
He grabbed her hair and pulled her up just enough to slap his cock against her cheek. "You want these socks on my feet while I fuck you?"
"Yes," she panted. "Leave them on. Don't take them off."
She stripped fast, climbed onto the bed on all fours, and pushed her ass back. He stepped up behind her still wearing the filthy socks. His socked foot pressed down between her shoulder blades, pinning her chest to the mattress. The damp fabric felt hot against her skin. He rubbed the sole along her spine, leaving a trail of sweat and spit.
Then he shoved his cock into her pussy in one rough thrust. She cried out, clenching around him. While he fucked her hard, he lifted one socked foot and pressed the sole against her face. She licked it frantically, tongue sliding over the wet cotton, sucking the fabric between her lips as his balls slapped her clit.
"Smell it while I pound you," he ordered. "Tell me how bad those socks stink."
"They reek," she gasped between licks. "They smell like your sweat and feet and I fucking love it. Don't stop."
He pulled out, flipped her onto her back, and straddled her chest. His socked feet planted on either side of her head. She grabbed his cock and stroked it while she lifted her head to suck on the toes of his left sock again. The fabric was stretched tight over his toes; she could feel the shape of each one against her tongue. He jerked his cock faster, aiming at her open mouth.
"Keep worshipping those socks," he said. "I'm gonna cover your face."
She sucked harder, moaning around the dirty fabric as he came. Thick ropes of cum splattered across her lips, her tongue, and the sock she was licking. Some of it soaked into the cotton. She swallowed what she could and kept licking the mess off his sock, cleaning every drop with long, greedy strokes.
He didn't let her stop. He moved down, shoved her legs apart, and pushed back inside her. One socked foot stayed near her face so she could keep sniffing and licking while he fucked her. Her orgasm hit fast and messy, her pussy squeezing his cock as she moaned into the damp sole pressed against her mouth.
After he came again, deep inside her, he pulled out and wiped his cock on her thigh. She stayed on her back, breathing hard, still nuzzling his socked foot like she couldn't get enough.
"Tomorrow after the gym," she said, voice raw. "I want the really sweaty ones."
He pressed his foot harder against her face, grinding the wet fabric over her nose and mouth.
"You'll get them," he said. "And you'll lick every inch while I fuck your throat."
She closed her eyes and took another deep breath of his socks, already aching for the next time.
