Wife, deep down, have you secretly desired this? Haruki Sato, the married woman with big tits, is transformed into a sex slave pet as her brother-in-law's thick, hot cock thrusts deep inside her, her breasts roughly squeezed while her pussy is savagely pounded. Surrendering completely to pleasure, she loses all sense of self, her body spiraling into uncontrollable depravity. Under restraint and domination, she becomes nothing more than a cumdump, craving relentless cunnilingus and brutal fucking. From Cherish label by DOC, in the series My Brother’s Wife Became My Sex Slave Pet.
