A raw, intense BDSM training session unfolds as a bound trainee's limits are pushed to the extreme. Roughly gagged, they're made to endure a relentless threesome, their ass stretched and filled by master trainers' massive cocks. Hard fucking, flogging, and whipping ensure no inch of flesh goes untouched, as the trainee's body becomes a canvas of red welts and glistening juices. In this depraved ritual, submission knows no bounds.
