A helpless cock, bound and gagged, awaits its fate at the hands of a merciless mistress. She teases it with her luscious body, rubbing her soaking pussy along its length, before impaling herself on it, her tight walls squeezing it deliciously. But this is no mere fucking; she's got devices, whips, and clamps, ready to torment his balls until they're purple and swollen. She laughs at his pitiful moans, her cunt clenching around his cock as she brings him to the brink of agony and ecstasy.
