Sultry brunette Gia DiMarco has an obsession with mocha-skinned beauty Skin Diamond's ass! While normally this would lead to all sorts of butt kissing for Skin, Gia's fixation leads to all sorts of hot lesbian BDSM.Bound with her plump, round ass ready for femdom violation, Gia goes wild zapping Skin's posterior with a zapper. Her yelps of surprise and pain to the electro BDSM are muffled by the gag in her mouth. Lovingly, Gia spits onto Skin's asshole but all of that is a prelude to electrosex with a hook penetrating Skin's butt. Finally, Gia works three plugs in Skin's ass, inducing orgasms more than it does discomfort.
