A eager sissy slave receives his first lesson in the art of serving big black cock. The dominant mistress ties him to a chair, spreading his legs wide. She teases his mouth with a monstrous, uncircumcised black cock, making him lick and suck the sensitive head. As he struggles to take more, she rewards him by pushing a thick, black dildo into his virgin ass, making him moan around the cock in his mouth. She laughs, 'You're gonna learn to love this, sissy.'
