[Yumika Saeki takes on an ultra-hardcore deep throat challenge that surpasses her previous work!] A beautiful and kind mother accepts the deep throat training of a cruel teacher for her daughter. A sudden throat-throbbing deep throat! A top-down rape that simultaneously violates her throat and pussy! A blindfolded deep throat that deprives her of vision and instills fear, pain, and pleasure, and a 3P throat-throbbing fuck that makes her mouth and vagina loose! A large amount of vomit that makes her soaking wet and a resonant sobbing voice are proof of love, or are they the nature of a natural throat toilet... She can never go back to being a normal mother.
