Gagged and restrained, the sub is at the mercy of their Master's whims. The room echoes with the symphony of leather meeting flesh, each strike drawing a gasp from the bound one. The Master, their voice a velvety growl, commands the sub to count, to thank them for each pang of pleasure. The sub, tears streaming down their face, obeys, their body writhing in a dance of pain and ecstasy. The Master, their cock straining against their leathers, decides to extend the session, ready to delve deeper into the sub's limits.
