Diligent Sockslave
This obedient sockslave is kneeling on the dirty floor of the train carriage and diligently studying his mistress’s blue and white, spotty socks whilst she listens to music on her headphones high above him.
Afterwards, when they get home, she and her husband (who is seated beside her on the train) will remove the sockslave’s helmet in order to examine the electronic patterns in his brain waves recorded by the device throughout the day, and if the slave’s menial mind is deemed to have deviated away from his mistress’s socks for even a nanosecond, he shall be sorely whipped! And rightly so, for a sockslave has no business thinking about anything other than his mistress’s socks on her feet.
