At any moment now, My guests will be arriving for My private party. Among My Lady friends attending, there will of course be some male partners and some slaves. My maid has not even finished washing the dishes yet, but there is something important I want to check up on before the guests arrive. As part of her maid duties for the evening, she will be required to suck cock on demand. Whether it be from one of My male guests or from one of the Mistresses wishing to empty her slave’s balls, My slut will be on her knees for most of the evening with her cocksucker throat open for cum disposal. I make My maid perform one last practice suck on My strap-on, as I verbally detail all of the cock pleasing duties she is to perform during the next few hours. With so many cocks to suck and so much cum to be swallowed, I want to be sure she’s up to the task. Oral endurance is a must and maximum dick draining will be her only focus while I supervise and enforce it all.
