The rhythm of the concert still echoes in her mind as she kicks off her heels, revealing her black Converse. She's got a different beat in mind now - the beat of a heart racing with desire. She straddles her partner, her sneakers pressing down on his cock, feeling the heat and hardness. The cock-crush begins, her feet sliding up and down, twisting and turning, as she grinds her soles into his sensitive flesh. The cockbox is tight, the pressure intense, but the pleasure is undeniable. With a final stomp, she feels the cock spasm, releasing a torrent of cum that coats her sneakers.
