Femdom FFM Facesitting Tease

Surprise for my locked sub: My sexy girlfriend shows up… inflatable collar strapped on and pumped tight around his neck… then she takes her seat – perfect ass grinding on his face, deep and slow, while we make out passionately right above him, tongues deep, moans mixing, giggling… his cage throbs in vain, light touches edge him mercilessly… pure FFM tease, hot kissing in his face and cruel denial – how long before he loses it completely?
