There is a relatively simple yet incredibly hot move that can be done princess-on-slave (also super-hot with lezdom) where the princess puts her foot on the back of the slave's head and pushes it down on the cock/dildo which combines many different fantasies of forced bi, being helpless to the princess's feet/power, being a whore/slut. It allows the princess with minimal effort to completely control and humiliate the slave to their core.
 
Other quick ideas that I bet people would find hot: the princess pushes the shock-collar button with her toes/feet instead of her hands/thumb (again, the humiliation of the slightest flick of her foot controlling the slave is very erotic)... the cuck/slave's chastity is decided by the princess's boyfriend/alpha (super-hot when the princess is referred to as master" and the bf referred to as "sir")- the humiliation of another guy having the say over your chastity is ultimate humiliation and having to beg a man is so pathetic. Anyways, incredible content overall from BP and I am in the camp of meaner/crueler/bitchier and the bullying/repeatedly reminding your slaves of their worthlessness/inferiority/place beneath you being my favorites and especially lezdom too!
