A sweat-soaked footjob, the sub's toes curl in ecstasy as their mistress grinds her heels into their crotch, the rough texture of the socks adding a delicious friction. She pays special attention to the sensitive spots, the arch, the ball of the foot, making the sub gasp and moan, their cock throbbing with need. The room is filled with the sound of wet, sucking noises as she brings them closer and closer to the edge, only to pull back, teasing them mercilessly.
