Sofia was in for a rude awakening. Being her first time under a fat BBW ass, she thought she could take it. Rubi sat on her and Sofia was immediately filled with regret. Being the petite weak sub she is, she could barely fight for her life. She was overpowered and overwhelmed by the giantess ass and struggled beneath it till she peed all over herself. She used up all her strength to fight for air that she gave up and K.O'd at the end.
