Nina was dreading this session. Her hands were tied up by her mistress Rubi because she was being stubborn and within no time, she was receiving back to back relentless butt drops that made her squeal. Rubi had so much energy and unleashed it all on her puny sub. Afterwards, she decided to rest her fat ass on her face while she humped Nina and stimulated her clit while squeezing her hard between her thick thighs that stifle someone easy. By the end of the session, she had learnt to be an obedient slave.
