In the dimly lit dungeon, Mistress Adelina Noir oversees her slave P's anal training. She commands him to strip, revealing his chastity cage. His cock twitches, hungry for release, but his Mistress has other plans. She presents a hefty, glistening anal plug, her eyes gleaming with anticipation. P's asshole clenches, but at the sight of Mistress Adelina's dominance, he relaxes, allowing the toy to slide in. She fucks him with it, his moans filling the room. Next, she introduces a larger dildo, stretching P's asshole to its limits, preparing him for the ultimate taboo.
