Sadist kadın doktor tarafından kölenin anal genişleme tedavisi

When the slave catches a cold and is resting in the infirmary, a female doctor comes in and says, "I'll treat you, hehehe," and makes a hole in the slave's underwear, laughing and saying, "Oh! Your anus is completely visible! How embarrassing, hahaha." The doctor inserts her finger into the slave's anus to expand it, then inserts an electric dildo and plays with it by vibrating it. The doctor inserts a dildo that is thicker than the electric dildo, and then an even thicker dildo, one after another, into the slave's anus and stirs it around, expanding it. The doctor puts on a strap-on and has the slave suck her dick, then pushes it deep down her throat, laughing at the slave's suffering. When the doctor's dick is wet enough, she inserts it into the slave's anus and starts fucking him. The slave is in suffering, but the doctor becomes excited seeing this and continues to fuck the slave's anal and expand it.
