Gentlemen, this is the perfect foreplay: no sex at all, just slapping, beating, hurting, pissing, spitting and maltreating your girls for 1 hour to your sole unrestrained enjoyment. You'll fuck like gods after that.
Turned upside down, ass fucked, balls slapped, humiliated, degraded, hurt. Yet the smile on the Goddess' face and the sound of her laughter makes it all worth it.
