Initiation of a submissive sex slave in the hidden underground room

In the dimly lit, secret cellar, a trembling girl is bound and gagged, awaiting her master\'s arrival. This isn\'t just sex; it\'s domination, submission, and training for a life of servitude. The master, a dominant with a penchant for bondage, initiates his new sex slave into their twisted world. The intensity builds as he thrusts his massive member into her tight, terrified mouth.
