In a dimly lit Swiss dungeon, Cello and SexyLi20, two 20-year-old German maids, are subjected to rigorous sexual training. With their hands bound behind their backs, they're forced to deepthroat each other's wet pussies and hard cocks. The master watches, his own thick member throbbing with anticipation. He takes turns fucking their tight holes, making them swallow his load. The room fills with the scent of sex and the sound of their moans, muffled by their gags, as they're pushed to the brink of orgasm, only to be denied release.
