A femdom expert teaches her new sub the art of ball-busting blowjobs. The minx tentatively licks his balls, earning a stern smack. She's soon enthusiastically slurping and choking on his cock, while he pinches and twists her nipples. He grabs her hair, driving his hips forward, making her gag and retch. She's rewarded with a slap across her cheek, leaving a red handprint. The lesson ends with her covered in spit and cum, gasping for air, but eager for more.
