In this extreme BDSM session, a submissive is bound and gagged, ready to serve their master's every desire. The master, a sadist with a penchant for the rough and extreme, takes control, their hard cock slipping into the sub's mouth, fucking it with increasing force. The sub's eyes water as they're pushed to their limits, their body squirming in its bonds, trying to escape the relentless onslaught of their master's cock in their throat. The master, enjoying the sub's struggle, continues to dominate, their voice a low growl of satisfaction as they use the sub's mouth for their pleasure.
