The mistress orders her slave to get on all fours on the bed, then blindfolds him, puts a ball gag in his mouth, and clamps his nipples. After spanking him repeatedly and reddening his buttocks, she penetrates his ass with a plug. Although the plug struggles to enter, she insists and then orders him to stick it all the way in. With the plug completely inside his ass, the mistress orders the slave to lie on the bed and stand with his legs wide open, then masturbates him until he cums into a small glass container. Finally, she pours all the cum from the container into the slave's mouth and makes him swallow it all.
